PRI-CDR/SEC-CDR (Call Detail
Recording Link)
The CDR feature records detailed call information on all incoming and outgoing
calls 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. Refer to the PDATA-PT section
for information on the system port connectivity. External CDR output devices
include:
■ 94A Local Storage Unit (LSU)
■ TELESEER CDR Unit
■ Call Accounting System (CAS)
■ Call Detail Recording Unit (CDRU)
■ Printer
■ Host computer
■ Personal computer (PC)
■ Customer-provided equipment
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.
