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.
