General Description
The BR 1/10 U-BR1TE is a line card that plugs into a single
channel slot of an ADTRAN BR1/10, and provides the
interface between the Digital Subscriber Line (DSL) to the
customer's location and the T1 carrier facility.
The BR1/10 and BR 1/10 U-BR1TE have been designed
to provide a maximum concentration for 2B+D Basic Rate
ISDN (BRI). The BR1/10 and BR 1/10 U-BR1TE are used
in both central office terminal (COT) and a remote terminal
(RT) applications. The BR1/10 Channel Bank will
interoperate with other channel bank systems that are
WECO D4 compatible, such as SLC-96 and SLC-5
®
systems.
The BR1/10 and BR 1/10 U-BR1TE operate in the TR-
NWT-000397 3-DS0 mode allowing up to eight individual
BR1TE cards for each T1 carrier facility. In the 8 DSL mode
the BR1/10 is compatible with channel bank systems
equipped with TR-NWT-000397 compliant ISDN channel
unit, such as the ADTRAN D4 U-BR1TE II, and the
ADTRAN SLC-5 U-BR1TE.
