ADTRAN Network Card DSLAM Octal IDSL User Manual

Octal IDSL  
Total Access DSLAM Octal IDSL Module  
Product Features  
Legacy ISDN deployments were intended to  
deliver 144 kbps over a single pair. The  
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.  
Eight ANSI T1-601.1992  
compliant ISDN U-interface  
circuits running from 64 to  
144 kbps data rate

ADTRAN 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.  
Maximum of eight DLCIs per  
IDSL loop  
64 kbps, 128 kbps and 144 kbps  
data rates  
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.  
Loopback support at the  
U-transceivers and ATM  
interface for fault isolation  
Performance monitoring  
support (FEBE and NEBE) at  
each interface point (8)  
Test packets sent toward line  
for diagnostics  
Craft and SNMP management  
interfaces  
Software download capability  
for application code and FPGA  
configuration data  
Industry-leading 10-year  
warranty
