The ATA is capable of receiving dial pulse or DTMF address signaling from
the analog equipment.
The ATA uses the 2nd channel of the TCM loop to add an analog port to the
digital terminal. It has an RJ11 type jack accessible from the back of the
telset.
The analog interface of the ATA is a 2-wire source, providing A and B leads
(tip and ring) across which analog equipment (modem/fax) is connected. The
loop length is >100 feet. The analog interface of the ATA is compatible with
the port types listed in Table 65.
Refer to Analog Terminal Adapter Quick Reference Card for detailed
information on this feature.
Follow the steps in Procedure 67 on page 377 to add the Analog Terminal
Adapter (ATA) to the telephone and to connect it to a FAX or modem. The
ATA is supported on Meridian Digital Telephones only.
