1. GENERAL

This practice provides installation and maintenance information for the ADTRAN SLC-5 U-BR1TE III w/ PWR and DDS Loopbacks (U-BR1TE III). Figure 1 is an illustration of the unit. The 1102040L4 is a direct replacement and fully compatible with the previous ADTRAN SLC-5 U-BR1TEs, including the 1100040L1, 1100040L3, 1102040L2, and the 1102040L1.

ISDN/DDS

The U-BR1TE III 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.

Functional Description

The U-BR1TE III is a channel unit for use in the AT&T® SLC Series 5 and Series 2000 Digital Loop Carrier Systems. The SLC-5 U-BR1TE III w/PWR and DDS Loopbacks combines the functionality of a standard SLC-5 U-BR1TE III and a U-Repeater Powering Module which will simplify the installation of the U-Repeater when deployed from a Digital Loop Carrier (DLC) facility. 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 III can be used in SLC-5 Central Office Terminal (COT) deployed as Feature Package

C(FPC), and SLC-5 Remote Terminals (RT) deployed as Feature Package C without Autocut (FPC/AC) and Feature Package B. The U-BR1TE III will also operate in SLC-2000 COTs and RTs when deployed as SLC Mode 1. Clear Channel capability (B8ZS) is not required of the T1 facility if zero byte substitution (ZBS) is enabled on the U-BR1TE III. The U-BR1TE III plugs into a single physical slot of

the channel bank. Three time slots are required for
