Hardware Description and Reference for Avaya ... - Avaya Support

● Up to four simultaneously-ringing ports
● Type 1 caller ID and Type 2 caller ID
● Ring voltage generation for a variety of international frequencies and cadences
A hard-wired ground wire is added for each IROB-to-earth ground
External interfaces on the CO trunk side
Caller ID
The following requirements apply to the external interfaces on the CO trunk side:
● The tip and ring default input impedance is 600 ohms. The default impedance can be
configured to accommodate other tip and ring impedances. One such impedance is the
900 ohms that is used in Brazil. Another is the complex impedance that is used in the
European Union.
● A hard-wired ground wire is added for each IROB-to-earth ground.
● The MM714 supports DTMF, MF, and pulsing.
● The MM714 supports R2MFC address signaling.
● Acceptable loop range for the CO trunk is 18 to 60 mA
● The MM714 supports direct inward and outward dialing (DIOD) for Japan.
The MM714 Analog Media Module supports up to four incoming caller ID (ICLID) on analog CO
loop-start trunks for all supported countries that require this feature. The MM714 supports Type
1 caller ID (CID) devices, and firmware signaling requirements are implemented on a per-port
basis. The firmware supports these formats:
● Single Data Message Format (SDMF)
● Multiple Data Message Format (MDMF)
● Caller ID generation on line ports
The MM714 accommodates on-hook transmission, which is necessary to receive caller ID
signals.
A call can still be terminated on a trunk that is administered for ICLID. The call is terminated
even if there is no ICLID information or error in transmission of ICLID information. Japan is an
exception.
