Service Conditions

SMDR can be programmed to record all outgoing calls or toll calls only, depending on the customers' requirements.

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.

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 dialed.

Supervision of the status of the external RS-232C terminal is not supplied.

There are two kinds of SMDR features as follows:

a. Built-in SMDR

The MP card has two RS-232C ports for SMDR. This card provides memory for a maximum of 1024 calls, and provides a record of a maximum of 255 trunk calls simultaneously for a maximum of 6-digit extension number.

Note: In case of built-in SMDR, if the station number is a 7- or 8- digit number, the upper one or two digits are sent as Calling office Number and the last six digits are sent as Calling Number in the call record format.
