ADTRAN D4 U-BR1TE V - Manual

1 Section 61104020L4-5, Issue 3 61104020L4-5C
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
Issue 3 of this document includes 2B leased mode
operation and revises the CLEI code.

ISDN 2B1Q Interface
Installation and Maintenance
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.
