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
