Description: Monitors active WAN call sessions, statistics, and connection parameters on Ascend access equipment.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is ASCEND-CALL-MIB?

ASCEND-CALL-MIB is a proprietary Ascend MIB for WAN/dial access equipment that monitors active call sessions and their statistics. It exposes per-call data such as connection parameters, negotiated speed, duration, and status, alongside aggregate call statistics for the chassis. Its monitoring role is essentially a live software/session-status view, comparable to tracking process or job status on a server: operators see how many calls are currently active, how they were established, and can detect abnormal call drops, failures, or capacity exhaustion in near real time. It depends on the underlying physical/line interface MIBs (such as the T3 or DS3 ATM network MIBs in this same family) for the trunk or channel each call is carried on. It was deployed on Ascend dial-up, ISDN, and WAN access concentrators at ISPs, used both for capacity planning and for troubleshooting connection failures. Engineers can download the ASCEND-CALL-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-CALL-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Ascend WAN/dial access concentrators (e.g., MAX, Pipeline, TNT series)

Monitoring Examples

An operator polls the active call session table for per-call connect time, port/channel, and negotiated line speed, then totals concurrent sessions against the chassis's available channel capacity. A sudden rise in call-termination or connection-error counters relative to successful connects points to a WAN trunk, modem bank, or channel problem rather than a client-side issue. Per-call statistics also make it possible to identify one specific line or channel that repeatedly drops calls.

What Can Be Monitored

active call session count
call connection parameters (speed, duration)
call statistics and error counters
port/channel usage per call
call termination reasons
