PSTN Gateway DS1 Active DS0 Channels (Nb)

Type

SNMP (collection)

Description

Number of active DS0 channels that are active for a specific serial E1/T1 interface.

Because there is no specific OID for this measurement in the MIB, this metric assumes the following:

•1 Call = 1 DS0 Channel = 64 kbps

•Throughput (in or out) / 64000 = Active Channels

Syntax

Dim I1 AS Integer Default * NAME If;

V1=OIDVAL( 8 * delta(ifOutOctets.%I1) );

V2=OIDVAL(delta(sysUpTime.0)/100);

V3=OIDVAL((%V1/%V2)/64000);

V4=OIDVAL(int(%V3));

V5=OIDVAL(distrib(ifType.%I1, "==18:1,default:0"));

%V4*%V5

Generic Database Alias

None.
