•
On-demand access using the craft port, inband or Facility Data Link
(FDL) access to stored DS1 PM data including:
–
Current status
–
Sectionalized events
–
Blockage indicator (a quality-of-service summary statistic)
–
ANSI 15-minute and 24-hour statistics
•
On-demand access to stored HDSL PM data
•
AIS-CI insertion toward the network upon detection of incoming LOS or
AIS at the network interface
•
RAI-CI insertion toward the network upon receiving RAI from the CPE,
if the signal from the network is not impaired
•
Loopback toward the network with AIS insertion to the CPE equipment
•
Adaptive frame format conversion if enabled in:
–
SF to ANSI T1.403 ESF
–
Non-standard to standard ANSI T1.403 ESF (for example, addition
of remote units)
–
AT&T PUB 54016 to ANSI T1.403 ESF (for example, addition of
remote units without interference with the 54016 poll response)
•
Nonintrusive access to real-time performance monitoring data
(CPE-provided SF or ESF signal)
Network Elements (NEs), such as the ADA T3AS test and performance
monitoring system, can be used to collect the performance monitoring data to
allow full-time surveillance of the DS1 signal. By installing T3AS at a
network boundary (for example, Interexchange Carrier [IEC] Point of
Presence (POP), and a remote unit at the NI), the Local Exchange Carrier
(LEC) can monitor the performance of its portion of the network, and rapidly
sectionalize circuit problems. By sectionalizing problems in its network the
LEC can know what trouble exists and who is responsible without external
involvement.
