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.
