Legacy ISDN deployments were intended to
deliver 144 kbps over a single pair. The
ADTRAN
TM
Total Access
®
DSLAM Octal IDSL
module provides data interfaces between the
eight U-interface ISDN line circuits and the
Total Access DSLAM backplane which
connects to the CSM or TSI switch module.
The card occupies a single access slot in the
shelf. This card may be plugged into any one
of the 28 general purpose, line card slot posi-
tions of the Total Access DSLAM. The card is
designed to work with the DS3 CSM, 128-port
CSM, OC-3c CSM, and the DS3 TSI switch
module.
The Octal IDSL module supports both
FRF.5 and FRF.8 frame interworking stan-
dards. The data rate on each line interface
may be 64 kbps, 128 kbps or 144 kbps. The
data rate is software configurable through
either the craft menus, SNMP, or TL1 manage-
ment interfaces.
The U-interface pairs are accessed at the
eight 64-pin Champ connectors on the
backplane. Each circuit carries 144 kbps serial
data over the subscriber loops, up to a
maximum distance of 18,000 feet, over a
26 AWG copper pair. This service can be deliv-
ered over standard repeatered U-interface
circuits.
