Videx 275-2W PAXB Interface unit Intercom to analogue telephone switchboard connector

PABX interface unit: The 275 allows the intercom to be connected to an existing PABX analogue telephone switchboard. By integrating with the phone system, those using the intercom to request access can be answered on existing telephones throughout the building. Most PABX telephone systems have the ability to transfer calls to another phone, to transfer calls to different departments or even to call groups of phones together. Calls from the Videx door entry intercom can be placed on hold and transferred to another extension to be dealt with - just like any normal incoming telephone call.
