Item Information
The Analog Station Interface (ASI) provides standard 2500 type DTMF service at any extension port. Use the ASI when the sytem requires a limited number of anlog interfaces without reducing the number of outside lines. The ASI lets you easily connect auxiliary equipment such as Integrated Voice Messaging.
ASIs require DTMF detection (i.e., receivers) for outgoing calls. ASI P/N 89749 has its own DTMF receiver.
