Multi-service access node
A Multi-Service Access Node (MSAN) is a device typically installed in a telephone exchange that connects the customer's telephone lines to the core network to provide telephone, ISDN, and broadband such as DSL on a single platform.
Before using MSANs, telecom providers typically had a variety of separate devices, including DSLAMs , to provide the various types of services to customers. The integration of all services on a single node, which normally handles all data streams via IP or Asynchronous Transfer Mode (ATM) to a central network element , can be more cost-effective and potentially offer customers new services faster than before.
A typical outdoor MSAN housing consists of narrowband ( POTS ) and broadband ( xDSL ) connections, batteries with rectifiers, an optical transmission unit and a copper line distributor.
