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
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.
