iMarc DSL CSU/DSU Overview
The iMarc
™
DSL (Digital Subscriber Line) CSU/DSU is a component in the iMarc
system. This system allows you to perform end-to-end service level management
across a hybrid DSL/Frame Relay network. Service providers can isolate and correct
problems remotely from their NOC (Network Operations Center).
The CSU/DSU has an IDSL interface and is a manageable frame relay-aware endpoint.
The following diagram shows a typical use of the iMarc DSL CSU/DSU in a network.
The iMarc DSL CSU/DSU is available in two feature sets:
Diagnostic Feature Set provides basic frame relay and diagnostic capability.
Advanced SLM (Service Level Management) Feature Set provides basic features,
plus service level management and reporting capability.
