Category: Network Interfaces, Vendor: ACC/Ericsson

Description: Manages ISDN interface configuration on ACC/Ericsson access routers, including switch type, TEI management, and SPID provisioning for BRI/PRI circuits.

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 ACC-ISDN?

ACC-ISDN is a legacy ACC (Advanced Computer Communications) proprietary MIB reporting ISDN digital-subscriber-loop interface configuration and HDLC/LAPD statistics on ACC bridge/router terminals. Its subscription table records switch type, channel mode, admin status, diagnostic level, and manual TEI (Terminal Endpoint Identifier), while a statistics table reports HDLC inbound/outbound packet/octet/error/discard counts and LAPD unsolicited responses, peer SABME count, N200 errors, sequence errors, received FRMRs, control errors, and info errors. As a configuration/performance MIB it lets an administrator diagnose ISDN Layer 2 (LAPD) instability via error-frame counts. It is deployed on legacy ACC ISDN bridge/router terminals. Engineers can download the ACC-ISDN file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ACC-ISDN. 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

  • Legacy ACC ISDN bridge/router terminals

Monitoring Examples

An administrator checks accIsdnStatLapdN200Errors to diagnose a flapping ISDN D-channel connection on a legacy ACC bridge/router terminal.

What Can Be Monitored
