61245023L1-5B Section 61245023L1-5B, Issue 2 1 1. GENERAL Functional Overview The ADTRAN T1 Nx64 HTU-R is a network terminating unit which uses High-bit-rate Digital Subscriber Line (HDSL) technology to transport T1 data over copper loops. Each loop operates over a single pair of copper wire and carries half of the total bandwidth along with a small amount of overhead for maintenance and performance monitoring functions. Figure 1 is an illustration of the T1 Nx64 HTU-R. The T1 Nx64 HTU-R is a standalone unit which contains an integrated Data Service Unit (DSU). This eliminates the need for a separate DSU. The T1 Nx64 HTU-R provides Nx56 kbps or Nx64 kbps data transmission capability. Possible data rates range from 64 kbps to 1.536 Mbps and 56 kbps to 1.344 Mbps.
