Rx PRM
The NetLink-T1™ transmits ANSI performance report messages
once a second when the framing mode is ESF. When the ESF Data
Link is set to ANSI T1.403, the unit recognizes PRMs with addresses
of 38h or 3Ah. The address 3Ah indicates the PRM is coming from a
Carrier, whereas the address 38h indicates the PRM is coming from a
Customer. When the ESF Data Link is set to AT&T TR54016, the unit
recognizes Carrier-originated PRMs, which have an address of 3Ah.
Rx PRM: 00010000000300023289
