ADTRAN TR-NWT-000829 User Manual
The ADTRAN SLC-5 U-BR1TE is an ISDN range extension product for
delivering Basic Rate ISDN to remote locations across SLC Series 5 Digital
Loop Carrier (DLC) systems. In addition, the U-BR1TE will operate in SLC
Series 2000 DLC configured for SLC Mode 1 operation. The SLC-5 U-BR1TE
provides a standard U-interface that operates at 160 kbps full-duplex over
a single twisted pair. The U-interface converts to a three DS0 format,
allowing transportation of 2B+D data as well as end-to-end maintenance,
performance, and test information. The ADTRAN SLC-5 U-BR1TE operates in
both Central Office Terminals (COT) and the Remote Terminals (RT); conforms to applicable standards and requirements; and performs all Layer 1
maintenance and performance monitoring functions per TR-NWT-00397
and TR-NWT-000829. The SLC-5 U-BR1TE provides a distinctive metallic
DC test signature for identifying the LT or NT operating mode and is compatible with the Metallic Loop Test (MLT).
The SLC-5 U-BR1TE occupies one physical slot in a SLC-5 channel bank.
To deliver 2B+D service, the SLC-5 U-BR1TE uses the DS0 time slots
associated with the occupied physical slot and the required remaining
time slots of the adjacent physical slot. SLC-T U-BR1TE provides a NULL
function which allows an older SLC-5 channel bank to provide 2B+D ISDN
without upgrading the common equipment. The SLC-5 U-BR1TE meets the
1s density requirements of the T1 carrier system through zero byte substitution and associated flags in the D channel DS0 time slot as specified in
TR-NWT-000397.
Maintenance, testing, and status information is displayed on the front
panel. An RJ-45 jack provides DS0 access to B1 and B2 for testing with
standard digital test sets. The rotary Address Select Knob along with a DS0
test set allows for local B1 or B2 loopback test access of up to six ISDN network addresses and the NT1 in the network-to-customer direction. The CR
and LP indicators provide instantaneous synchronization and loopback
status for the T1 carrier facility (CR) and the U-interface (LP) and the status
of the Layer 1 activation is provided with ACT indicator. The ADTRAN
SLC-5 responds to network initiated mp-eoc commands including B1, B2,
and 2B+D loopbacks.
