TM 1 3821-A2-GZ40-10 November 1996 COMSPHERE 3821Plus 6-Port DTE Interface Assembly (Feature 3821-F1-002) Installation Instructions Document Number 3821-A2-GZ40-10 November 1996 6-Port DTE Interface Assembly Installation The following instructions are intended for use in conjunction with the COMSPHERE 3821Plus Modem User’s Guide (3821-A2-GB20). Please read the Important Safety Instructions in that document before proceeding with the installation. Install the NIM The DTE interface assembly covers the network interface module (NIM), so the NIM must be installed first. The 3821Plus modem requires one of the following NIMs: • Part number 3000-F1-027 (3821Plus NIM with Make Busy and Service Line Features), or • Part number 3000-F1-028 (3821Plus NIM without Make Busy and Service Line Features) Install the NIM and connect its cables according to the instructions in the user’s guide. Communications adapters designed or configured for a 4-wire leased line, Digital Data Service, or programmable PSTN interface cannot be used with a 3821Plus NIM, and should not be installed in the same side of the carrier. Loosely Attach the DTE Interface Assembly The 6-port DTE interface assembly can be mounted over any two adjacent slots on the left or the right side of the carrier. If you are installing only one NIM for 3821Plus modems, the DTE interface assembly must be mounted on the same side of the carrier as the NIM. 1. Feed the tabs at the bottom of the DTE interface assembly into the slots in the carrier. See the illustration below. 2. Insert the screws provided. After tightening them, loosen them one turn. You will tighten them in a later step. 496-14876 3000 SERIES CARRIER SLOTS TABS DTE INTERFACE ASSEMBLY A A B B C C
