PRI-CDR/SEC-CDR
The CDR feature records detailed call information about every incoming and
outgoing call on specified trunk groups and sends this information to a CDR
output device. The two physical links can be administered for connecting external
CDR output devices to the system. They are identified as the primary CDR
(PRI-CDR) link and the secondary CDR (SEC-CDR) link. The CDR device
connects to the system via a data module (PDM, MPDM, DTDM) connected to a
port on a TN754 Digital Line circuit pack that is administered as a data extension.
A CDR device can also be connected through an ADU to a port on TN726B. The
CDR link to the processor is via a system port. A system port is comprised of a
port on the TN726B Data Line circuit pack and a port on the TN553 Packet Data
circuit pack connected to each other in a null-modem fashion. See
(Packet Data Line Port)'' on page 8-868

CDR Link Maintenance provides a strategy for maintaining the link between the
system and an external CDR output device. The strategy includes a set of tests
for periodic diagnosis, detection of errors during normal operation, actions for
troubleshooting, and raising alarms for serious problems. CDR Link Maintenance
uses a try-and-wait mechanism for maintaining the CDR link. If the CDR link is
torn down due to an error, CDR Link Maintenance tries to bring the CDR link up. If
the Link Setup fails, CDR Link Maintenance will wait for 30 seconds before the
next retry. If the number of retries reaches a threshold (two), a Minor alarm is
raised for service attention.
