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.

Revision History

This document has been revised to correct switch
SW1-5 function described in Table 2.

Installation and Maintenance

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
