1. GENERAL
This practice provides installation and maintenance
information for the ADTRAN U-BR1TE III w/PWR. Figure
1 is an illustration of the U-BR1TE III w/PWR.
The U-BR1TE III w/PWR is a line card for use in a WECO
compatible D4 and an AT&T SLC-96 channel bank. The
U-BR1TE III w/PWR incorporates the functionality of a
standard U-BR1TE III and the ADTRAN U-Repeater
Powering Module which will simplify the installation of
ADTRAN U-Repeaters when deployed from a Digital
Loop Carrier (DLC) facility.
The U-BR1TE III w/PWR allows transport of Basic Rate
ISDN over T1 carrier facilities and provides an ISDN
2B1Q U-interface that will supply span power for one of
two modes of operation. In one mode of operation, the
U-BR1TE III w/PWR supplies a constant 43 mA to span
power an ADTRAN ISDN U-Repeater II or U-Repeater
III. The other mode of operation allows the U-BR1TE III
w/PWR to provide a constant -120 VDC to span power
an ADTRAN I-NIU.

automatically determines the appropriate mode of
operation, without requiring an option selection.
While the span powering mode is intended to be used in
an Adjacent-to-Customer location, such as a remote
central office or remote terminal, the U-BR1TE III w/
PWR may also be configured for Adjacent-to-Switch
(COT) and Tandem Office applications. Clear channel
capability (B8ZS) is not required of the T1 facility if zero
byte substitution is enabled. The U-BR1TE III w/PWR
plugs into a single slot of the D4 and the SLC-96 channel
bank, and typically requires three time slots for transport
of 2B+D information. Block error rate performance over
the T1 facility is monitored and is available to the
network. The U-BR1TE III w/PWR provides for up to
eight hours of performance history for both the T1 carrier
and the U-interfaces.
Revision History
This is the first issue of this practice. Revisions to
subsequent practices will be summarized in this
paragraph.
