PRI-CDR/SEC-CDR (PRI-CDR Link)
The CDR feature records detailed call inf ormation on all incoming and outgoing
calls on specified trunk groups and send s this information to an CDR output
device. The two physical link s can be administered for connecting extern al CDR
output devices to the system. They are id entified as the primary CDR (PRI-CDR)
link and the secondar y CDR (SEC-CDR) link. The CDR link can be administered
to a data extension or the EIA port on the TN798 Processor circ uit pack that
provides a standard EIA-232C interface. The external CDR output devices are:
■94A Local Storage Unit (LSU)
■TELESEER CDR Un i t
■Call Accounting System (CAS)
■Call Detail Recording Unit (CDRU)
■Printe r
■Host computer
■Personal computer (PC)
■Customer-provided eq uipment

DEFINITY Enterprise Communications Server Administrato r’s Guide

for
details of the CDR feature.
CDR Link Maintenance provides a strateg y for maintaining the link between the
system and an external CDR output devic e. The strategy includes a set of tes ts
for periodic d iagnosis, detection of er rors during normal operatio n, actions for
troubleshooting, and raising alarms for serious problems. CDR Link Maintenanc e
uses a try-and-wait mechanism for mai ntaining the CDR link. If the CDR link is
torn down due to an error, CDR Link Maintenance in tends to bring the CDR link
up. If the Link Setup trial fails, CDR Link Maintenance waits 3 0 seconds before
the next retry. If the number of retries reaches the value of a threshold (two), a
Minor alarm is raised for service attenti on.
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 interfac e.
■From a data channel on the TN798 Processor circuit p ack to a data
extension where the CDR output device co nnects via the standard EIA
232C interface.
