Avaya 120A5 CSU Module Channel Service Unit is a refurbished compact CSU module designed for use with compatible Avaya DS1 circuit packs. When used in combination with a supported DS1 circuit pack, the 120A CSU family provides essential functions normally associated with an external Channel Service Unit while allowing the CSU hardware to be incorporated into the communications system.
The compact design provides an alternative to installing a separate external CSU. The module is designed for straightforward installation and does not require DS1 cabling or option switch settings. This makes the 120A CSU family useful for organizations maintaining compatible Avaya Definity, MultiVantage, and Communication Manager equipment.
