Overview This chapter provides the following general information about the 3708: • Overview • Physical description • Operating modes • Network configurations • Monitoring and controlling the 3708 • Summary of advantages. The 3708 provides a physical and logical interface for connecting ASCII end-user devices! to an SNA network. It has 10 communication ports that can be defined for various network configurations and operating modes. The network can contain ASCII hosts, which include personal computers, as well as SNA hosts. Physical Description The 3708, which is shown in Figure I-Ion page 1-2, is small, lightweight, and portable. It consists of two modular, customer-replaceable hardware components: a base and a cartridge. The back panel of the base contains 10 numbered ports for connecting hosts and ASCII end-user devices. The 3708 measures 400 mm by 355 mm by 105 mm (15.8 in. by 14.0 in. by 4.1 in.), weighs approximately 5.6 kg (12.3Ib), and can be placed on a shelf in a standard 19-inch rack. 1 ASCII end-user devices use asynchronous start~stop data transmission and include displays, printers, keyboard printers, keyboard displays with attached printers, plotters, personal computers, and devices that use ANSI X3.64. Chapter 1. The 3708 and Its Advantages 1-1

Operating Modes Cartridge Light '-----Base Power On/Off Light Not Ready Light The 3708 provides three modes of operation, which it can perform simultaneously, for different network configurations: • 3270 applications running on an SNA host. The 3708 provides protocol conversion mode for communication between an ASCII end-user device and 3270 applications running on an SNA host. This mode changes a start-stop data stream from an ASCII device into a 3270 data stream and provides 3274 Control Unit functions, including 3270 full-screen support. • Line-by-line applications running on an SNA host. The 3708 provides protocol enveloping mode for communication between an ASCII end-user device and line oriented applications running on an SNA host. In this mode, the 3708 surrounds the data stream from an ASCII device with SNA headers. Devices that normally communicate with host applications through the start-stop support of the Network Terminal Option (NTO) can communicate through the 3708. NTO start-stop support is not required for 3708 operations and can be eliminated from the communication controller. • Applications running on an ASCII host. The 3708 provides ASCII pass-through mode for communication between an ASCII display and applications running on an ASCII host. This mode passes a start-stop data stream between an ASCII display and an ASCII host without changing the data stream in any way. Network Configurations The 3708 provides 10 communication ports that can be defined for various configurations of SNA hosts, ASCII hosts, and AscII end-user devices. The host may be directly attached or may be remotely attached over nonswitched (leased) lines. ASCII devices may be directly attached or may be. remotely attached over switched or nonswitched lines. Line speeds of up to 19200 bps can be used. 1-2 3708 Planning and Installation

connect to separate hosts, or both can connect to the same host. SNA Host* 3708 ASCII Devices ASCII Devices Figure 1-2. Two Kinds of SNA Host Connections * For a list of SNA hosts that the 3708 supports, refer to "SNA Hosts" on page 3-1. As many as nine ports can be defined for ASCII hosts. Each of these ports can connect to separate hosts, or multiple ports can connect to the same host, depending on the host. Figure 1-3 on page 1-4 shows a configuration with one SNA host and one ASCII host. Chapter 1. The 3708 and Its Advantages 1-3

* For a list of SNA hosts that the 3708 supports, refer to "SNA Hosts" on page 3-1. When a 3708 port is connected to an SNA host, multiple end-user devices can communicate at the same time over that one line. When a 3708 port is connected to an ASCII host, only one end-user device at a time can communicate over that line. However, multiple devices can communicate at the same time with an ASCII host if each device has a separate line to the host. Control Terminal A control terminal can be used for monitoring and controlling the 3708. Any display that operates in protocol conversion mode can be the control terminal if it is logged on to the 3708 in control terminal mode. The 3708 allows only one display at a time to be logged on in control terminal mode. The control terminal can be either directly or remotely connected to the 3708. The control terminal is also used to define the configuration of the 3708. An IBM-supplied configuration allows many types of displays to be used as a control terminal for defining the initial configuration of the 3708. The 3708 provides default keyboard mappings for these terminals. (Refer to "ASCII End-User Devices" on page 3-2 for a list of the default terminals.) You must have one of these terminals to define the initial configuration for the 3708. After initial configuration, other types of displays can be defined for use as a control terminal. "Step 3. Logging onto the Control Terminal" on page 12-5 contains step-by-step procedures for logging on to the control terminal. 1-4 3708 Planning and Installation

• Define or change: Host ports and host access Device ports Control terminal access Control terminal password Port passwords Translate table Keyboard mappings Printer access World Trade language to be used for 3708 logon Suppression of 3708 logon screens. • Display information, such as: Configuration data Response time statistics Alert log and other error information. • Monitor the 3708 by checking: - Port status - Data transmitted on lines connected to the 3708. Note: If a printer is connected to the 3708, the control terminal screens showing configuration information can be printed as a local copy operation. Summary of Advantages The 3708 provides the following advantages: • It reduces communication costs by reducing the number of telecommunications lines needed, by reducing the number of communication controller ports needed, and by allowing a display with a connected printer to share a single communication downstream line. • It supports personal computer file transfer through the IBM PC/HOST File Transfer and Terminal Emulator Program (FTTERM). • It allows you to manage the configuration and microcode fixes of the 3708s in a network from a central control point. This management capability is provided by 3708 Feature 3525 (pluggable Cartridge with Central Site Configuration) and its associated PC aid. • It supports network management by sending alert messages to NetView or to the Network Problem Determination Application (NPDA) and response time statistics to NetView or to the Network Logical Data Manager (NLDM) for displays that are connected for protocol conversion, and by notifying an SNA host of changes in the power status of attached ASCII end-user devices. • It supports multiple modes of operation. Protocol conversion, protocol enveloping, and ASCII pass-through modes can be supported simultaneously. • It eliminates the need for NTO start-stop support in the communication controller by providing protocol enveloping for ASCII end-user devices that are compatible with TWX 33/35. Chapter 1. The 3708 and Its Advantages 1-5

protocol conversion mode. The 3708 provides ASCII~to-3270 keyboard mappings for many displays and allows additional keyboard mappings to be defined at the control tenriinal. • It supports IBM 3270 Models 2,3,4, and 5 emulation when operating in protocol conversion mode. • It allows the sharing of printers. The printer can be defined to allow output from the host, local screen copies from one or more ASCII displays operating in protocol conversion mode, or both host output and local screen copies. It also supports printers that are connected to displays (MLU). • It reduces terminal costs by allowing inexpensive ASCII end-user devices to be used in an SNA network. • It provides flexibility by allowing a single ASCII device to be connected to either an SNAhost or an ASCII host (which may be a personal computer) and by allowing access to ASCII and 3270 applications at an SNA host. • It helps in migrating to SNA by allowing end users to access 3270 application programs through ASCII devices. • It provides security for data and applications by allowing an optional password for each port, by allowing host and printer access to be defined, and by ending a session whenever it detects an abnormal disconnection. • It provides an optional inactivity time-out that may be used to disconnect terminals, thus reducing security exposures and limiting dial charges on switched lines. • It connects to devices that use special characters or nonstandard codes by providing ASCII-to-EBCDIC translate tables. An additional translate table can be defined using the control terminal. • It allows the SN A host to dial out to devices in protocol enveloping mode. • It alliJws a display to dial out to an ASCII host in ASCII pass-through mode. • It supports transparent operations in protocol enveloping. Ports can be defined to allow transparent data flow to and from the host. This feature provides support for devices such as graphics displays, printers, and plotters. • It allows an operator to define the 3708 configuration and to monitor and control the 3708 by using an ASCII display as a control terminal. A password protects access to control terminal functions. When not used as a control terminal, the ASCII display is available as an end-user device. • It allows a port to be defined to allow protocol conversion, protocol enveloping, or both depending on the type of session requested by a host All ports can be defined to allow ASCII pass~through. • It allows a port to be defmed to automatically determine the parity and line speed (from 110 to 4800 bps and 9600 bps) for both switched and nonswitched lines. • It attaches to the IBM cabling system. 1-6 3708 Planning and Installation

restart at the control terminal. • It has a built-in, optional, extended diagnostic test program that is available with port external wrap testing. • It provides a one-year warranty and is supported by IBM service. Chapter 1. The 3708 and Its Advantages 1-7

This chapter describes the functions that the 3708 provides in protocol conversion, protocol enveloping, and ASCII pass-through modes. Protocol Conversion Display Support In protocol conversion mode, the 3708 provides all the functions in IBM 3274 Configurati

entering non-nuinetic data when the application expects numeric data.. The 3708 allows the end-user to override this function by typing: Any upper case character or symbol into the numeric field. A blank into the first position in the numeric field. While the blank occupies the first position in the field, the user can type any character into the numeric field. • It provides type-ahead key queuing, that allows the user to enter new keystroke sequences on the keyboard while a preceding keyboard sequence is being processed. This function allows a user to request the next screen before the current screen is completely displayed. The user can turn type-ahead key queuing on and off. • It provides enhanced null/blank processing, that allows the user to use either the space bar or the cursor move keys to edit and separate fields. The 3708 allows trailing blanks or nulls to move off the end of a line when the user is inserting data in that line. When the data is sent to the host, the 3708 converts imbedded nulls to blanks. The user can turn eDhanced null/blank processing on and off. • It supports highlighting and color for certain classes of displays. Refer to IBM 3708 Network Conversion Unit Description for more information. Light-pen operations can be simulated using a Cursor Select key sequence. • It supports the following 3270 commands: Erase All Unprotected Erase/Write Erase/Write Alternate Read Buffer Read Modified Read Modified All Write. • It supports the following buffer formatting and control orders: Start Field Set Buffer Address Inset Cursor Program Tab Repeat to Address Erase Unprotected to Address. • It notifies the user when it detects a framing or parity error by updating the status line. To continue, the user must reset the display using the 3270 reset function. This function can be suppressed by configuring the nonstandard operating bit 5 to 1. Refer to "Non-Standard Operations" on page 14-3 for more information. • It allows the conttol terminal operator to display response-time statistics and error information, such as the alert log, at the control terminal. In addition, the response~time statistics and alerts can be displayed at the host using NetView or Network Logical Data Manager (NLDM) and the Network Problem Determination Application (NPDA). Full support for 3708 alerts is available only through NetView. 1-1 3708 Planning and Installation

In protocol conversion mode, an ASCII printer or keyboard printer looks like an IBM 3287 Printer, Model I or 2 to the SNA host. The ASCII printer or keyboard printer can be configured to operate in three ways: System mode. The host sends print data to the printer, which is either an LU type I or an LU type 3. The output format for an LU type I printer is controlled by SNA character string (SCS) characters. For an LU type 3 printer, the output can be formatted or unformatted. Unformatted output is controlled by 3270 data stream compatibility (DSC) print orders. Local mode. A copy of the screen of a display that is operating in protocol conversion mode is printed at the printer. The host can start a local copy by sending a command, or the user of the display can select it with a print key sequence. When a printer port is configured for local mode, it cannot be used for LU type I or LU type 3 print operations. Shared mode. The printer is available for both system mode and local mode operation. A local copy can be performed whenever the printer is not being used for an LU type I or LU type 3 print operation. Keyboard printers operating in protocol conversion mode are supported as output devices and must be defined as printers. Up to 256 characters (8-bit data with no parity) can be used with an output device operating in L U type I SCS transparency mode. The 3708 supports the following input from a keyboard printer that is directly connected to the 3708: • Hold Print/Enable Print • Cancel Print (LU type I SCS only) • PAl and PA2 (LU type I SCS only). Multiple Logical Unit Support A printer connected to an auxiliary port on a display that supports remote access to its auxiliary port can be defined as a second LU on the 3708 port to which the display is connected. The printer can then be used in system mode, local mode, or shared mode. This support is referred to as multiple logical unit (MLU) support and operates only in protocol conversion mode. If a printer is connected to an auxiliary port on a display and is not defined to the 3708, the printer can be used only for screen copy operations that are initiated by the user. The user enters a predefined key sequence that the 3708 echoes back to the display. Input from devices that are connected to the auxiliary port of a display is not explicitly supported; any such input is assumed to be for the display. Chapter 2. Operating Mode Functions 2-3

type 1 with a Network Terminal Option (NTO) appearance. The 3708 does not provide any device-specific support other than that provided by NTO for devices that are compatible with TWX 33/35. The application program must provide any device-specific support. The 3708 supports the following functions in protocol enveloping mode: • It mayor may not modify the ASCII data, depending on how the port is configured. The data can be modified by using a translate table, delay characters, substitution characters, and other options that are defined during configuration. If the data is translated from ASCII to EBCDIC, the 3708 can use one of two standard translate tables or a user-defined translate table. • It can provide a delay after a Carriage Return, Vertical Tab, Form Feed, or Horizontal Tab. • It can use either a default substitution character or a user-defined substitution character when it detects a data error. When it detects a parity error in a character, the 3708 can replace the character with the Parity Error Substitution character configured in the 3708. When it detects a framing error, the 3708 always replaces the framing error with the Parity Error Substitution character. • It can use up to five different turnaround characters, which are defined during configuration, to control communication. When the 3708 receives a line turnaround character from an end-user device, the 3708 sends data from the device to the host. Because the 3708 does not control the keyboard in protocol enveloping, users must know when they can and cannot enter data. A character string that tells the user when to enter data can be defined for each port. To define the character string, see "Send Read Prompt" on page 13-40. In addition, a port can be configured to enable the 3708 to echo characters that are entered at the keyboard. • It can provide for transparent data flow. The 3708 can support 256-character sets and output-only devices, such as printers and plotters. • It can allow the host to dial out to devices. For more information, refer to IBM 3708 Network Conversion Unit Description. ASCII Pass-Through In ASCII pass-through mode, the 3708 serves as a wire connection between an ASCII end-user device and an ASCII host. The host and the end-user device are responsible for data and protocol error checking. N~te: A programmable modem can be installed on a port configured as an ASCII host. The 3708 allows the user to dial out through the programmable modem in ASCII pass-through mode and gain access to an ASCII host, printer, or other device. 2-4 3708 Planning and Installation

SNA Hosts This chapter describes the connections between the 3708 and the hosts and between the 3708 and the ASCII end-user devices. The 3708 can be connected to as many as two SNA hosts using either point-to-point or multipoint links. It is defined as a separate physical unit (PU) to each SNA host link. In addition, the connection to the host can be direct, or it can be remote using a nonswitched (leased) line. Line speeds as high as 19200 bps can be used. SNA host connections use the EIA 232C interface. The 3708 uses the SDLC protocol to communicate with an SNA host, and it uses half duplex data transmission on either full duplex or half duplex communication facilities. If a particular end-user device will always be used with one specific SNA host, the 3708 port to which the device is connected can be defined to suppress the 3708 logon and/or host-selection screens. Because the service priority of the 3708 is in descending order, ports 10 and 9 are recommended for SNA host connections. Connect the first SNA host to port 10 and the second SNA host to port 9. The 3708 can be connected to an SNA host through any of the following: • IBM 3720 Communications Controller • IBM 37x5 Communications Controller • IBM 3710 Network Controller • IBM 43xx with an Integrated Communication Adapter • IBM 4701 Model 003 Finance Communication Controller (using Alternate Line Attachment adapter, SNA Primary to attach to the 4700) • IBM 4702 Branch Automation Processor (using the Alternate Line Attachment adapter, SNA Primary to attach to the 4700) • IBM 8100 System Data Link or Direct Attach • IBM System/36 Communications Attachment (using the 3274 Remote Attach Support) • IBM System/38 Communications Attachment (using the 3274 Remote Attach Support). Chapter 3. Host and ASCII Device Interfaces 3-1

• NetViewfully supports the 3708 alerts and response time monitor (RTM) data. NetView contains both Network Problem Determination Application (NPDA) and Network Logical Data Manager (NLDM). • Network Problem Determination Application (NPDA), Version 3 or later, supports only the specific and general cause codes of 3708 alerts. • Network Logical Data Manager (NLDM), Release 2 or later, supports response time statistics. The 3708 can be connected to multiple ASCII hosts using point-to-point links. The connection can be direct, or it can be remote using a nonswitched (leased) line. ASCII host connections use the EIA 232C interface. Line speeds as high as 19200 bps can be used. The speed used by the host.and the. speed used by the end-user device should be the same. Full duplex transmission must be used. ASCII End-User Devices The 3708 can be connected to ASCII end-user devices using either a direct or remote connection. End-user device connections use the EIA 232C interface or, for distances over 15 meters (50 feet), the EIA 422A interface. A remote connection can use either switched or nonswitched lines. Line speeds can be as high as. 19200 bps. Protocol Conversion Mode For protocol conversion mode, the 3708 supports various displays, printers, and keyboard printers. 3-2 3708 Planning and Installation

Plan for the parts that need to be ordered. See Chapter 11, "Ordering the 3708" for more information. 9. When the site and configuration planning is complete, follow the procedures in Chapter 12, "Installation Procedures" to install the 3708 and to enter the configuration parameters. Chapter 4. Planning Checklist 4-1

Use the following procedures to plan the 3708 configuration: • Complete the Network Planning Form on page 4-4 to help visualize the physical connections to the 3708. • Complete the Port Definition Form on page 4-5 to help organize and plan the network connections for the terminals, hosts,and printers. "Protocol Conversion Mode" on page 3-2 lists the terminals that the 3708 supports. • After you have defined the types of devices (hosts, terminals, printers) that are connected to each port, plan the configuration parameters for each device. Follow the procedures in Chapter 13, "Configuration Procedures" to configure each port. Chapter 12 provides the following information about the parameters for each type of device: The screens that are displayed on the control terminal for each type of device The options that you can enter for each field on the screens. Before starting the configuration, you need the following information: Host configuration. Prepare the host system generation. Refer to IBM 3708 Network Conversion Unit Description for more information. Downstream devices. Gather information about XONjXOFF, line speed, parity, interface type (EIA 232C or EIA 422A), and line type (switched or leased) for the devices that you are connecting to the 3708. Refer to the user manuals for the devices for more information. For a list of device manuals, see Appendix K, "Manuals for Default Protocol Conversion Displays." Use the Device Information Form on page 4-3 to collect the information for each device. Communications network environment. When attaching devices to the 3708 through modems, telephone lines, and public access networks, you should be aware of certain parameters associated with the connection facilities that can affect the 3708 operation, such as XONjXOFF, parity, stop bits, and communication speed. 4-2 3708 Phullling and Installation

terminal, use the configuration forms in Appendix C, "3708 Configuration Forms" to indicate the correct option for each configuration parameter.

You can order a 1.5-meter (6-foot) power cord in addition to the cord that is shipped with the 3708. 2. High voltages are not available in the USA and Canada. Make sure that your site has the electrical power to match the order. Branch Circuits and Grounding A dedicated branch circuit of 15 amperes is recommended for the 3708. For safety and proper machine operation, each branch circuit must be grounded to a dedicated equipment ground, not to a neutral ground. The branch circuit must have an insulated grounding conductor that is equal to the size of the phase conductor and is tied to a common ground point at the distribution panel. A single insulated and isolated grounding wire should run from the distribution panel ground point to the service ground or to a suitable building ground. Conduit must not be used as the only means of grounding. 5-2 3708 Planning and Installation

Electrical grounding of the 3708 is essential for safety and proper machine operation, so be sure the power receptacle is properly grounded. If you have any questions about the grounding of the receptacle, contact an electrician. Since the 3708 is small and lightweight, one person can move it safely during installation or relocation. If the 3708 cables are not installed under a raised floor, be sure the cables are arranged so there is adequate space for people to move around the 3708 safely. The 3708 cables, particularly those for a direct connection using the EIA 422A interface, are not protected against lightning. They must not be placed outdoors. To ensure the physical security of the 3708, do the following: • Allow only authorized persons to press switches on the 3708 and to use the control terminal. • Use unique passwords for port access and control terminal functions rather than the default passwords. • Exclude control terminal access to public ports. Chapter 5. Planning for Installation 5-5

This chapter describes the 3708 maintenance service offerings, tells who to call for installation technical assistance, outlines how to get remote assistance for problems not solved by problem handling-procedures, and gives the location of the repair identification number. The 3708 problem determination and service procedures provide the following: • Comprehensive internal diagnostics • Only two replaceable elements, which are a base and a plug-in cartridge • Communication network management support by providing alerts and by collecting performance statistics • Control terminal support for configuration, monitoring, and problem determination for either local or remote connection • Remote assistance for diagnosing machine problems and for applying microcode fixes through a modem and phone line access that you provide. These features reduce the cost of maintenance and the problem resolution time. Reviewing the Service and Warranty Options Service Options Warranty Options This section describes various service and warranty options that are available for the 3708. The IBM Maintenance Agreement provides maintenance service options. The following service options are available: Service Option Description Customer on-site exchange IBM arranges for the delivery of an exchange unit to your location and for pick up of the failing unit. IBM on-site exchange An IBM representative comes to your location and exchanges a functioning unit for the failing unit. If you purchase the IBM on-site exchange option, you can also purchase optional periods of maintenance service, which extend the hours in which service is available. The warranty period is for 1 year and is serviced under the customer on-site exchange service option. However, you can select the IBM on-site exchange service option during the warranty period for an additional charge. Contact the local IBM branch office for more information on warranties and maintenance agreements. Chapter 6. Planning for Service 6-1

The 3708 is designed for remote access by both you and IBM service representatives. For example, the network personnel using a control terminal from a remote location can access 3708 alert data and review error logs to perform problem determination. You can also use the control terminal to monitor data and signaling lines on the 3708's downstream ASCII ports. Remote assistance is part of the 3708 maintenance service offerings. It allows an IBM service representative to dial out to a 3708, to run extensive diagnostic tests, and to apply microcode fixes if necessary. Remote assistance can minimize outages that would otherwise require the unnecessary iep1acement of the base or cartridge and can minimize the delay in waiting to receive a new cartridge with updated microcode. To receive remote assistance, you must provide a modem and phone line access for the IBM service representative. Installation Technical Assistance Contact the marketing representative where the 3708 was purchased if you have technical questions about any of the following: • Ordering information for the 3708 base, cartridge, and cables • Installation • Configuration • System integration • Application/host programming considerations. Replacement Elements and Remote Problem Assistance Before calling for service, use the problem-determination procedures in IBM 3708 Network Conversion Unit Problem Determination to isolate the problem to a failing unit if possible. After completing problem determination, contact IBM for service as described in "Calling for Service" on page 6-3. To be eligible for this assistance, the 3708 must be either under warranty or covered by an active IBM service agreement. 6-2 3708 Planning and Installation

Use the following telephone number to receive replacement units, existing microcode fixes (MCFs), or problem assistance: • In the continental United States or Puerto Rico, call the following number: 1 800 428-2569 (toll free) • In other countries, call the appropriate support group. Note: The telephone numbers are subject to change. If the number has changed, call the IBM marketing representative or the local IBM branch office. Calling the 800 Number When you call the 800 number, an IBM customer service coordinator briefly discusses your situation and asks for the type of machine, the machine serial number, the repair identification (RID) number (see page 6-5), the name of your company, and a phone number where you can be reached. The customer service coordinator also performs an entitlement check to determine the type of contract or warranty agreement in effect. The IBM customer service coordinator is not the IBM service representative for the 3708. If you wish to obtain existing microcode fixes (MCFs) for your level of microcode, the customer service coordinator will forward your request to the IBM service representative, who will make arrangements with you for the installation of the MCFs. If you have a problem and have successfully completed the problem determination procedures and isolated the problem to a unit, you are given instructions on how to receive a replacement unit. If you are unable to complete the problem determination procedures or if the procedures indicate a microcode problem, further assistance in problem determination will be provided. The information about the problem will be forwarded to a 3708 specialist who will call you back. The service representative will call you and either provide a solution for the problem or work with you to solve the problem. Chapter 6. Planning for Service 6-3

IBM can help through remote assistance if you are unable to resolve a 3708 problem using the procedures in IBM 3708 Network Conversion Problem Determination and if one of the following is true: (1) the 3708 is still under the I-year warranty, or (2) you have purchased IBM maintenance service. Remote assistance can include consultation with an IBM service representative for problem diagnosis by IBM through a remote connection (through a modem and phone line access that you provide). The network management personnel can also use the modem for configuration and problem management of devices that are connected to the 3708. Hardware and Configuration Requirements Traces and Logs For remote assistance, you must provide telephone facilities for a 1200 bps switched, auto-answer connection. This includes a modem with the following characteristics: • For the USA only, use a direct-connect, Bell 2I2A-compatible modem with operating speeds up to 1200 bps in full duplex mode when connected to the direct distance dial network. The modem must operate over a 2-wire switched line. For countries other than the USA, use a V.22-compatible modem. • EIA 232C compatible interface. Any downstream port used for remote assistance must be configured identically to port 3 as described in Appendix A, "IBM-Supplied Configuration." If this is not compatible with the normal mode of operation, reconfigure a port for that mode before receiving remote assistance by temporarily reinstating the IBM -supplied configuration. (Refer to IBM 3708 Network Conversion Unit Problem Determination for more information.) When not in use for remote assistance, the port is available for connection to an end-user device. The 3708 can be configured to deny access to the host from a port that is assigned to remote service. Microcode Fixes (MCFs), patches, and diagnostic traps are applied and stored in the base unit hardware (EEPROM). They are not stored in the cartridge. If you replace your base unit, you must have any MCFs, patches, or traps applied to the new base unit. As part of the problem determination process, the IBM representative often requires you to provide certain additional materials. The most frequently requested are an NCP Line Trace, a VT AM Buffer Trace, or a PT2 Trace of both upstream link and the failing downstream line. Please be prepared to obtain and provide these traces when requested. Also, you may be requested to obtain and provide copies of the 3708 Error Log and 3708 Alert Log at the time of failure. Making this information available can greatly enhance problem determination and speed the resolution of your problem. 6-4 3708 Planning and Installation

The repair identification (RID) number enables the IBM customer service coordinator to perform an entitlement check to determine the warranty or service option that is in effect. Locate the machine type and repair identification (RID) number of the failing unit. The RID number is in the following locations: • Just above the power cord on the back of the base • On the cartridge. Apply the RID label that is shipped with the 3708 to the cartridge when the 3708 first arrives. • In the vital product data storage area on the logic board of the 3708 base. The RID number is displayed on the 3708 logon screens when logging on to the 3708. Generally, the RID number located on the cartridge and the base is the same as the RID number displayed on the 3708 logon screens. If they are not (they will differ if you have exchanged the base element), use the control terminal to enter the RID number located on the base (and cartridge) into the 3708's vital product area (EEPROM). EEPROM is a nonvolatile logic circuit in the 3708 that retains information regardless of whether the 3708 power is on or off. Maintaining the same RID number on the base, the cartridge, and within the 3708's vital product area ensures smoother and faster service if you need to exchange 3708 elements or need remote service for microcode. Chapter 6. Planning for Service 6-5

This chapter describes the 3708 microcode update procedure. It includes how to register for microcode update notification, what to expect in the notification, how to order microcode updates, and what to do with outdated microcode. Note: The cartridge holds all of the 3708's operational microcode. This code cannot be downloaded from a host. Microcode fixes (MCFs) and patches are stored in the base unit and can be downloaded from the host. Refer to Chapter 8, "Planning for Central Site Configuration" for more information. How to Register What to Expect How to Order To register for microcode update notification, you MUST fill out the registration form that comes with the 3708 and send it to the address indicated on the form. You must fill out and send in this registration form to be notified of any microcode updates. After you send in your registration form, IBM 3708 Microcode Support personnel will notify you with Engineering Change (EC) Memos as new engineering changes for microcode become available. The memo gives you the new EC number for the microcode and a list of the improvements and corrections contained in the update. Even if you have not encountered any problems, it is recommended that you install the updated microcode level to prevent possible future problems that may occur because of any changes in your operating environment. To order microcode updates without charge do one of the following: 1. Fill out the IBM 3708 Enhanced-Cartridge Ordering Form that is attached to the notification memo and send this form to the address indicated on the back of the ordering form. No postage is necessary. 2. Call the 800 number shown below, and be ready to give your RID number, customer number, address, and your name or the name of a person to contact. If you reach a recording when you call, please leave a message on the recorder and someone will return your call as soon as possible. If you have questions about receiving replacement cartridges: • In the continental United States or Puerto Rico, call the following number: 1 800 247-7118 (ton free) • In other countries, call the appropriate support group. Chapter 7. Planning for Microcode Updates 7-1

The new microcode will be accompanied by a copy of 3708 Enhanced Cartridge Receive/Exchange/Re~urn Instructions. The instructions tell you how to do the , following: 1. Install the new 3708 microcode 2. Return the old cartridge by: a. Packing the old cartridge in the shipping carton used to send you the new microcode. Please be sure the RID number is identified on all cartridges being returned. b. Attaching the prepaid mailing label enclosed in the carton c. Mailing the old cartridge within 5 working-days of receiving the new microcode. To receive future releases of updated microcode, you must return outdated cartridges to ffiM. 7-2 3708 Planning and Installation

This chapter provides planning information about IBM 3708 Feature 3525 (pluggable Cartridge with Central Site Configuration), Feature 3525 consists of a plug-in cartridge and a set of diskettes. Together, the cartridge and the diskettes allow you to manage and distribute configuration updates and microcode fixes to 3708s in a network from a central location. This feature eliminates the task of entering repeatedly the same configuration or MCF /Patch data into all 3708s in a network. IBM 3708 Pluggable Cartridge with Central Site Configuration IBM 3708 Central Site Configuration (CSC) uses the IBM PC to support configuration and Microcode Fix (MCF) management for the IBM 3708 Network Conversion Unit. For central site configuration, you must install the 3708 Feature 3525 plug-in cartridge. Central site configuration provides the following advantages: • A single data base of configuration information for all of the IBM 3708s in an installation • Menu-driven, user-friendly facilities for the creation, replication, and modification of IBM 3708 configuration information including these features: Port definition for host links and downstream terminals User-defined terminal definitions User-defined translate table definition. • A check of configuration information as it is entered and a warning to the user if potential errors exist • Configuration summary screens, including a quick reference port summary, a detailed port summary, a host configuration summary, and printer configuration summary • A method to retrieve existing configuration information from an IBM 3708 through a downstream port • A method to load configuration information through a downstream port or the SNA host link with NetView or NCCF V2R2 • A method to retrieve a microcode patch area from a 3708 that has been upgraded by IBM and the ability to distribute the microcode patch area to other 3708s in the network • Item-specific help screens and an online user's guide. Chapter 8. Planning for Central Site Configuration 8-1

• A 3708 with Feature 3525 (pluggable Cartridge with Central Site Configuration) Note: Central site configuration is available with 3708 Feature 3525 only. • An IBM PC with: - A 5.25-inch diskette drive A fixed disk An IBM Color/Graphics or Monochrome adapter attached to an 80-column display A minimum of 512K bytes of storage (640K bytes of storage are required if the PC is to run in control terminal mode). You can use an IBM Personal System/2. To run CSC on the Personal System/2, you must first convert the 5.25-inch diskettes shipped with the CSC Cartridge to the 3.5-inch format. If you plan to perform central site configuration through one of the 3708's downstream ports, you will need: • An asynchronous communications adapter operating in primary mode • A normal voice-grade, switched communications line (for switched connections only) • Modems (for switched connections only). A manual-dial Bell 212A-compatible or auto-dial modem that supports the . Attention Command Set and result codes, such as an IBM PC 2400 bps or IBM 58422400 bps Modem is required for switched connections. Modem eliminators, null modems, or 3708 DTE cables may also be used to attach the IBM PC to the 3708. For a description of modem connections as well as modem eliminator, null modem, and 3708 DTE cabling configurations, refer to, "ASCII Hosts and End-User Devices to a 3708" on page 10-8. Software Requirements The following software is required for central site configuration: • IBl\l PC DOS Version 2.0 or later • eZ-VU II Runtime Facility Version 2 (6317025). 8-2 3708 Planning and Installation

The following features are enhanced by the 3708 central site configuration feature and other network software options. Configuration Downloads from an SNA Host The IBM 3708 central site configuration aid can prepare configuration information in the form of NetView CLISTs for downloading through the SNA host link to the IBM 3708. NetView and NCCF Version 2 Release 2 support this method of transfer. The file transfer software support that sends the CLIST from the IBM PC to the SNA host must be provided by the end-user. For example, the IBM PC/HOST File Transfer and Terminal Emulator Program, FTTERM, (6476052) can be installed in the IBM PC to upload CLIST files to the SNA host. New 3708s with the CSC feature have port 10 defined as an active host port with the following characteristics: Option Station Address NRZI Data Encoding Permanent Request to Send Line Speed Line Type Field Length (2) (1) (1) (2) (1) Port 10 X'08' 1 (Yes) o (No -- Use Controlled Request to Send) 00 (External Clocking) L (Leased) This configuration allows new 3708s to be configured remotely from the host site. For multipoint lines, no other devices on the line can have SDLC Station Address of X '08'. If two or more 3708s are to be installed on a single line, each 3708 needs to be configured from the host one at a time. The SDLC Station Address X' 08 ' should be reserved as a utility address because 3708 hardware or software errors and user interaction can temporarily or permanently re-instate the IBM-supplied configuration. If the host line parameters are not compatible with the user's environment, new 3708s can be configured for host line characteristics at a main site, shipped to remote locations, and configured over the SDLC links. Control Terminal Emulation The 3708 control terminal diagnostic routines can be accessed through the use of the IBM PC and the central site configuration aid running in control terminal mode. In this mode, the IBM PC can retrieve the alerts and error logs. IBM software products that can support this feature are FTTERM, and the IBM 3101 Emulator Program (6024042). Notes: 1. If you plan to use your PC as a control terminal for the 3708 and you want CSC to log you on as a control terminal automatically, you must have the FTTERM or the IBM 3101 Emulation program installed. The emulation program must reside in the same directory on your fixed disk as the central site configuration program. 2. The IBM PC must have 640K bytes of memory to support this function. Chapter 8. Planning for Central Site Configuration 8-3

If central site configuration is perfonned through one of the 3708's downstream ports or the IBM PC is to run in control terminal mode, at least one downstream 3708 port must be dermed for the following parameters: • Port Excluded = N • Logon Screens Excluded = N • Terminal Type Screen (C2) = y • Host Selection Screen (C3) = Y • Control Terminal Access = Y • Password Retry Limit = 3 or greater • Transmit XONjXOFF = 1 • Line speed = 1,2,4,5,6,8, 10, 12, or 19 (110, 150, 300, 600, 1200,2400,4800, 9600 bps, or Autobaud) • Device Class = 1 (Keyboard Display) • Operating Mode = 1 or 2 (protocol Conversion or Dynamic) • Interface Type = 0 (EIA 232C) • Parity = 2, 3, or 6 (Odd, Even, or Autoparity) • Receive Queue Size = M or L • Bits/Character = 7 • Auto On-Hook = 1 (for switched lines) • Send Answertone = 0 (for switched lines) • Full Duplex Line = 1 • Echoplex = 1 • Pennanent Request to Send = 1. Note: Ports 3 and 7 in the IBM-supplied configuration for the 3708 are compatible with central site configuration. Refer to Chapter 13, "Configuration Procedures" for a complete description of these and other 3708 configuration parameters. 8-4 3708 Planning and Installation

If modems are used, the modem at the PC and the modem at the 3708 must be configured as follows: • Modems detect a change in Data Terminal Ready (DTR) signal and go on hook when DTR drops. • Data Set Ready (DSR) is raised only when a connection is established (not applicable for internal modems). • Carrier Detect shows whether or not Carrier is on. • Modems use the Attention Command Set and send the modem responses in words (verbose mode) and not in number codes (terse mode). • PC modem does not answer incoming calls. • The 3708 modem does answer incoming calls. • Modems do not echo characters. • Modems do not take over flow control (that is, the modem does not strip out XONjXOFF characters from the IBM PC or the IBM 3708). Technical Assistance See your IBM representative for assistance with problems related to the central site configuration aid. Ordering Information The Pluggable Cartridge with Central Site Configuration can be ordered with an IBM 3708 Network Conversion Unit. Spare Pluggable Cartridges with Central Site Configuration can be ordered by part number. A set of S.2S-inch, double-sided, double-density diskettes containing the central site configuration aid is included with each Pluggable Cartridge with Central Site Configuration feature. Chapter 8.

IBM PC/HOST File Transfer and Terminal Emulator Program This section describes the function of the IBM PC/HOST File Transfer and Terminal Emulator Program (FTTERM). It also describes the benefits of using FTTERM and lists the environments under which it works. Benefits and Functions FTTERM is a licensed program that supports IBM PCs communicating with an IBM SNA host through a 3708. The program gives the user of an IBM PC full-screen 3270 terminal emulation and file transfer capability when operating in protocol conversion mode with the 3708. The connection between the IBM PC and the 3708 is through the IBM PC's asynchronous communication adapter. An IBM PC running FTTERM can also emulate an IBM 3101 terminal and connect to the 3708 in protocol enveloping mode. This connection provides access to asynchronous applications at the IBM SNA host that formerly interfaced to the Network Terminal Option (NTO) licensed program in the 37x5. The IBM PC can also operate through the 3708 to an ASCII/asynchronous host connected to another port on the 3708. In addition, FTTERM can access network services independent of the 3708. The features of the PC/HOST File Transfer and Terminal Emulator program are summarized as follows: • Provides IBM PC file transfer capability both to and from the IBM host 3270 personal computer file-transfer programs while operating in protocol conversion mode with the 3708. See "Required Host Programs" on page 9-2 for the program product numbers. • Provides full-screen 3270 emulation, status line support, and four color or highlighting while operating in protocol conversion mode through a 3708. • Supports the 3708 feature that allows a printer and a display to share a single port in protocol conversion mode. • Provides 3101 emulation (character mode only) to: Asynchronous applications at an IBM host in protocol enveloping mode An ASCII/asynchronous host connected to another port on the 3708 - Online information services, such as the IBM Information Network.

If the modem eliminator redrives the signal, then each cable segment must not exceed 15 meters (50 feet). Otherwise, the combined cable length must not exceed 15 meters (50 feet). 5. Clocking is required, and may be provided by one of three different methods: Clocking from the 3708 The 3708 can provide clocking for all line speeds that the 3708 supports. If this method is chosen, then the modem eliminator or null modem must not provide clocking. Configure the 3708 SNA host definition option Line Speed for the desired speed, and configure the host for external clocking. Clocking from the host Some hosts can provide clocking for some line speeds that the 3708 supports. If this method is chosen, then the modem eliminator or null modem must not provide clocking. Configure the host for the desired clocking speed, and configure the 3708 SNA host definition option Line Speed for external clocking (option 00). Clocking from the modem eliminator or null modem Some modem eliminators or null modems can provide clocking for some line speeds that the 3708 supports. If this method is chosen, then set the modem eliminator or null modem for the desired speed, configure the host for external clocking, and configure the 3708 SNA host definition option Line Speed for external clocking (option 00). 6.

. An incorrectly wired cable or incorrectly operating eqUipment (modem, modem eliminator, host, or end-user device) that is connected directly to a 3708 port can prevent the 3708 from operating. This problem occurs if the cable or equipment applies a signal to one of the following port connector pins: 2,4, 12, 14, 18, 20, 21, 23, or 24. Example 1: ROLM DTI users must ensure that the DTI is configured correctly and that the DTI switch SI-1 is set to OPEN (No). Otherwise, the DTI applies a signal to pin 20 of the 3708, which may prevent the 3708 from turning on. Recommended switch setting for the ROLM DTI are as follows: Switch #1 (SI): Forced DTR On Carrier Detect and CTS Display Audible Signal Enabled Terminal/Computer" Option Originate Answer/Answer Off Hook Control Switch Slide Switch (S3): Modem/Terminal Option OPEN (No) Either OPEN or CLOSED Either OPEN or CLOSED OPEN (TERMINAL) CLOSED (ANSWER) OPEN TERMINAL Example 2: IBM 5841 users must set configuration switch 8 (Data Set Ready option) to OFF. Setting this switch to ON causes the modem to hold Data Set Ready high (active) at all times. If the 3708 port is switched, and Data Set Ready is active all the time, the 3708 does not enable the port. To avoid signals on pins 2, 4, 12, 14, 18, 20, 21, 23, or 24, it is recommended that 25-pin conductor cables not be used. Example 3: Some synchronous modems and modem sharing devices do not hold the TXD line at a MARK level after RTS is dropped. This prevents devices on the same multi-drop line from communicating with the host. The problem occurs when the line is configured for NRZI data encoding. The problem can be prevented by doing one of the following: • Configure the modem/modem sharing device to hold the TXD line at a MARK level when RTS is dropped • Configure the line for NRZ data encoding. 10-12 3708 Planning and Install/ltion

Port 3 is configured for auto baud/auto parity. b. Make sure that the modem settings match the device settings. c. See Chapter 10, "Planning for Cables" for information about the type of cables to use to connect the control terminal. See Appendix I, "Terminal Switch Settings" for the required switch settings for the terminal. You can use other ports besides ports 3 and 7 for the control terminal connection. See Appendix A, "IBM-Supplied Configuration" for the initial port definitions. After configuring the 3708, you can reconfigure all 3708 ports including ports 3 and 7 to connect to any supported device. Note: Make sure that the terminal values for XON/XOFF pacing and line turnaround character agree with the IBM-supplied configuration. 3. Turn on the 3708. 4. Turn on the control terminal. 5. If you are using a modem, establish the connection to the 3708. 12-4 3708 Planning and Installation

1. If the control terminal is remotely connected to port 3, press the carriage return key to start the logon screens. If the control terminal is directly connected to port 7, the logon screens should start when the terminal is turned on. If the logon screens do not start, press the carriage return key. Notes: a. At any time during logon and before the first control terminal screen (MlOO.O) is displayed, you can disconnect the control terminal from the 3708 by typing #### and pressing the carriage return key. b. The 3708 EC number, RID number, and part number may differ from the following examples depending on your microcode level, particular machine, and port. c. During logon, the control terminal operates in protocol enveloping (line-by-line) mode. In this mode, use the period key, carriage return key, or a defined line turnaround character as the ENTER key. You also can use the backspace function if you want to correct typing errors. Other cursor-positioning keys are not operational for logon. The 3708 displays a port password screen as follows: ======IBM 3708===EC A58809======RID 3708-001 88-0000076========PORT 07====== Cl: Type port password To disconnect from the 3708, type n####.n ===> Chapter 12.
