OC-3c/STM 1
Total Access 3000 DSLAM OC-3c/STM 1 Cell Switch Module for ATM
The ADTRAN OC-3c/STM 1 Cell Switch
Module installs into a single CSM slot in the
Total Access DSLAM chassis and interfaces
to the network via SC connectors that
attach to the circuit board through the
faceplate. A dual configuration is optional
for redundant capability, with the system
being fully functional with only a single
MUX installed.
Standard traffic types such as UBR, CBR,
rt-VBR, and nrt-VBR, are supported for data
and Voice over DSL (VoDSL) services. The
CSM employs traffic prioritizing and policing
on a per VC (Virtual Circuit) basis to ensure
proper delivery of customer data.
Efficient data delivery is maximized
through early packet discard and partial
packet discard. Substantial buffers are also
utilized to optimize data throughput.
The Total Access OC-3c/STM 1 CSM
supports both local and remote management.
Operation, Administration, Maintenance,
and Provisioning (OAM&P) tasks can be
performed through the OS interface on the
SCU. Remote management via Telnet, Total
Access Element Management System (EMS),
TL1, and SNMP is supported through the
SCU. Reporting and managing of the QoS is
also supported. The OC-3c//STM 1 CSM also
exercises synchronized Performance
Monitoring (PM) and provisioning between
active and standby units.
