APPLICATIONS
The ADTRAN U-BR1TE is suitable for use in both
Central Office and customer premises environments. The
use of a single wire pair for full-duplex operations greatly
simplifies the administration of cable plant. The capability
of the U-interface to serve mixed wire gauges, and nominal
distances up to 18,000 ft. make it the universal choice for
ISDN deployment.
The ADTRAN U-BR1TE is ideally suited when the
need arises to extend ISDN service beyond the normal
ISDN BR1/8 Bank (BR1/8)
The ADTRAN BR1/8 BR1TE bank provides an alternative
means of housing the ADTRAN U-BR1TE or T-BR1TE and
provides network termination for a T1 line. The BR1/8 contains
eight channel slots to accommodate up to eight U-BR1TEs or
T-BR1TEs. Each channel slot contains three DS0 timeslots
allowing all of the channel slots to be used when delivering
ISDN Basic Rate (2B+D) Service. The BR1/8 is an economical
means to offer ISDN Basic Rate via T carrier. Mounting slots
are provided for eight common equipment cards: a PAU, PCU,
OIU-2, RU, LIU, ACU, TU, and CAU. It is available in 23-inch
mounting.
servicing range. The ability to provide ISDN services
is only limited by the range of available T carrier lines.
In instances where the 2B1Q U-interface card is
not available in the digital switch, it is possible to use
ADTRAN T-BR1TEs and U-BR1TEs in a mixed
application. This application allows the 2B1Q T1.601-
1992 U-interface to be delivered from a digital switch
which does not yet support it.
