Station Message Detail Recording (SMDR)
General Description
This feature provides a "call record" for all outgoing station to trunk calls and incoming trunk to station
calls. When the system is equipped with this feature, an RS232C output port is provided, permitting direct
interface with a customer-owned computer system. All output is in the ASCII format, and includes the
following:
•
calling station number
•
dialed number (24 digits maximum)
•
route number
•
start of call time
•
disconnect time
•
year, month and date
•
condition (Attendant handled, transfer, etc.)
•
ACCOUNT CODE [A-18]
•
AUTHORIZATION CODE [A-28] (8 digits maximum)
•
FORCED ACCOUNT CODE [F-7]
Operating Procedure
No manual operation is required. Call record outputs are produced automatically.
Service Conditions
1.
SMDR information facilitates analysis of trunk traffic and can be readily applied for cost allocation
or billing purposes.
2.
SMDR may be programmed to record either all outgoing calls or only toll calls, depending upon
user requirements.
3.
Both incomplete and abandoned calls will be discarded by the SMDR.
4.
When ROUTE ADVANCE [R-6] or LEAST COST ROUTING (LCR) - 3/6-DIGIT [L-5] is provided
with the system, SMDR will record the route number selected.
5.
The maximum number of digits dialed cannot exceed 24.
6.
When customer-owned computer equipment is connected via RS232C interface, SMDR
information will be transmitted directly to the computer as each call record is completed.
7.
If the outgoing call is directed to a trunk that cannot give answer supervision from the Central
Office, the start of call time is 18 seconds after the last digit is dialed. This timer value is set on
the System Data.
8.
If the distance between the system and the processing computer exceeds 50 feet (15 meters),
an asynchronous-type modem should be used.
