1. GENERAL

This practice provides installation and maintenance procedures for the ADTRAN D4 U-BR1TE V w/PWR and DDS Loopbacks, P/N 1104020L4. Figure 1 is an illustration of the U-BR1TE V.

ISDN/DDS

The U-BR1TE employs features for both ISDN and DDS transport. ISDN comprises the major functionality and is described in this section. A description of DDS functionality is located in Section 3.

Revision History

Functional Description

The U-BR1TE V is a line card that plugs into a single channel slot of an AT&T D4/SLC®-96 channel bank. It provides an ISDN U-interface and allows the transport of Basic Rate 2B+D information over T1 carriers and twisted pair wiring. The U-BR1TE V combines the functionality of a standard U-BR1TE V and a U-Repeater Powering Module which will simplify the installation of the U-Repeater. Span powering also allows deployment of 2-wire DDS when an IDSL OCU-R is used to terminate the ISDN local loop. This eliminates the need to provide AC power at the customer premises.

The U-BR1TE V is used at both the Central Office Terminal and Remote Terminal locations. Clear channel capability (B8ZS) is not required of the T1 facility if zero byte substitution is enabled. The U-BR1TE V plugs into a single channel slot of the D4 bank, but can require three time slots when transporting 2B+D information. Block error rate performance over the T1 facility is monitored and is available to the network.
