STATION MESSAGE DETAIL RECORDING (SMDR)
GENERAL DESCRIPTION
This feature provides a call record for outgoing station-to-trunk calls and incoming Trunk-to-Station
calls (including Data Call). This facilitates cost control by identifying trunk use and misuse by individual
stations. STATION MESSAGE DETAIL RECORDING (SMDR) enables call billing to customers and cli-
ents, and provides a means for checking local telephone bills.
STATION AP PLICATION
All stations
OPERATING PROCEDURE
No manual operation is required.
SERVICE CONDITIONS
1. SMDR can be programmed to record all outgoing calls or toll calls only, depending on the customers’
requirements.
2. An RS-232C compatible printer with an RS-232C reverse connection cable and/or a call accounting
unit must be locally provided. For outgoing calls, up to 26 digits can be recorded.
3. When customer provided computer equipment is connected using the RS-232C interface, SMDR
information will be transmitted directly to the equipment as each call record is completed.
4. One RS-232C interface port is provided. The following specifications apply to this port:
• Synchronization - Asynchronous
• Data Speed - 9600 bps (maximum)
• Code - ASCII 7/8-bit + parity bit
If the distance between the system and the processing computer exceeds 15 meters, an asynchronous
modem should be used.
5. If the outgoing call is directed to a trunk which does not supply answer supervision, SMDR will start
recording the call approximately 10 seconds after the last digit has been dialled.
6. Supervision of the status of the external RS-232C terminal is not supplied.
7. There are two kinds of SMDR feature as follows:
a. Built-in SMDR
• MP without expansion memory (standard) :up to 64 trunks
up to 256 calls
• MP with expansion memory (optional) :up to 256 trunks
up to 1,280 calls
