Verilink DPRI 2922
Features
The DPRI 2922 system has the following features:
T1 Digital
Transmission
Facilities
The DPRI system carries data traffic onto a T1 transmission facility.
Each port provides T1 transport bandwidth of n
× 56 kbit/s or
n × 64 kbit/s trunks.
Advanced
Automatic
Protection
Switching
The DPRI system provides Advanced Automatic Protection
Switching (AAPS) to an alternate T1 line using two hardware
options:
• DPRI with the CIM 29010, dual V.35 serial data ports
• DPRI with the CIM 29011, dual RS-449/EIA-530 serial data
ports
Dial Backup The DPRI system provides an alternate ISDN route for digital data
traffic when the regular T1 line is unavailable.
Alternate T1
Backup
The DPRI system provides an alternate T1 route for digital data
traffic when the regular T1 line is unavailable.
Crosspoint
Switch
The DPRI 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 DPRI 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
DPRI alarms are reported to the NCM. These alarms are viewed
using the NCM Craft interface, Telnet, SNMP, or Node Manager.
Advanced
Programmable
Architecture
All DPRI system hardware and software components can be
independently upgraded with product options and firmware
upgrades. Additional modules can be added within a node to
increase network channel capacity. CIMs and other modular
components can be added, upgraded, or replaced independently.
