Station Message Detail Recording (SMDR)
Strata Net generates call records for incoming or outgoing calls from the nodes in which they originated or
terminated. For example, if a station user in node 3 makes an outside call that is routed through transit
node 2 to gateway node 1 for connection to the public network, nodes 1 and 3 generate SMDR records;
node 2 does not.
The record in node #3 will include the Network DN of the calling station, the dialed digits and the OLG
number and Channel Group number used to access node #2. The record in node #1 will include the ILG
number and Channel Group number of the Strata Net trunk on which the call was received and the PSTN
trunk to which it was connected. The record format and conditions are the same as for a single node
system using the new format adopted for Strata CIX.
Station-to-station calls across Strata Net are considered internal calls and do not generate SMDR records
in any nodes. Abandoned Call SMDR records are only generated for incoming calls over local trunks.
Unforced account codes are generated from the node in which they originated. Forced account codes are
included in the records of the node that required them. Similarly, the node which provides DISA services is
responsible for checking the DISA Security code and for generating the SMDR record. The remote node
and the transit node will not generate the SMDR record.
Plowable buffers are usually attached to each network node and polled by a central call accounting
system. If the buffer is not available, the Strata CIX will buffer records as shown in the table below.
Equipment numbers, time stamps and call type designations assist the call accounting system in
associating records for the same call from different nodes.
