Compatibility
The supplied product information identifies this CSU family for use with Avaya DS1 circuit packs and with Definity, MultiVantage, and Communication Manager servers that support compatible TN circuit packs. The original information specifically identifies the following circuit packs in connection with the 120A2 revision:
- TN464E through TN464HP
- TN2464CP and earlier
- TN767D or TN767E
- TN2313 or TN2313AP
Because the supplied compatibility list specifically names the 120A2 rather than the 120A3, the installed DS1 circuit pack and system configuration should be verified before purchasing the 120A3 as a replacement. The supplied documentation below can also be referenced for additional installation and operating information.
The Avaya 120A3 CSU Module is a useful service component for organizations maintaining compatible Avaya telecommunications equipment. Its compact design and integrated CSU functionality can help preserve an existing DS1 installation while avoiding the additional space and cabling associated with a separate external CSU.
