Alternate T1
Backup
The QPRI system provides an alternate T1 route for digital data
traffic when the regular T1 line is unavailable.
Crosspoint
Switch
The QPRI system provides flexibility for designing data paths to
and from multiple AS2000 T1 modules across the backplane.
Incoming and outgoing channels can be set up to send data traffic.
Drop, Insert, and
Bypass Mode
The QPRI supports drop, insert, and bypass functionality via its
crosspoint switch. Further, the drop, insert, and bypass
configuration helps reduce the number of network (T1) links
among different sites.
Alarm
Management
QPRI alarms are reported to the NCM. These alarms are viewed
using the NCM Craft interface, Telnet, SNMP, or Node Manager.
