is adequate for most applications. The extended setting should be used only in applications where the
N

PRM -
Enabling performance report messages (PRM) allows the IQ 710 to send messages
across the facility data link (FDL) per ANSI T1.403. The terminating device at the telco may use this
information for management of the T1 loop.The IQ 710 supports PRM messages per AT&T Pub
54016 which is a poll/response type protocol. Because of this poll/response nature, the transmit PRM
option does not disable the IQ 710 from processing or responding to 54016-type messages.
