PRI-CDR/SEC-CDR (PRI-CDR Link)
The CDR feature records detailed call information on all incoming and outgoing
calls on specified trunk groups and sends this information to an 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 link can be administered
to a data extension or the EIA port on the TN798 Processor circuit pack that
provides a standard EIA-232C interface. The external CDR output devices are:
■ 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
Refer to
DEFINITY Enterprise Communications Server Administrator’s Guide
for
details of the CDR feature.
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 intends to bring the CDR link
up. If the Link Setup trial fails, CDR Link Maintenance waits 30 seconds before
the next retry. If the number of retries reaches the value of a threshold (two), a
Minor alarm is raised for service attention.
The following physical configurations are supported for the CDR link:
■ From the EIA port of Processor circuit pack to an CDR output device
through the standard EIA-232C interface.
■ From a data channel on the TN798 Processor circuit pack to a data
extension where the CDR output device connects via the standard EIA
232C interface.
