The Avaya 6424D+M telephone is a multiappearance digital telephone with 24 call
appearances and feature buttons.
The Avaya 6424D+M has a modular plug. This plug allows you to install a 100-A tip/ring module
to the desktop stand on the telephone for increased set functionality. The tip/ring module
provides a connection to adjuncts such as answering machines, fax machines, modems, analog
speakerphones, and Telecommunications Device for the Deaf (TDD) machines.
