Important

Example: The customer has a D2 card and uses M1 with the following default settings:

+FCLASS=0, B99, +CRC=0

When he receives a call (MTC), "RING" is displayed on his PC. The call can now be ac- cepted by means of "ATA". The DSA in the M1 accepts the call as a data call proper ir- respective of whether it is a data or fax call. The reason for this is that B99 causes the incoming service identifier to be ignored. With fax calls, this causes problems of many kinds because the user does not know which service is being used.

The command "AT+CRC=1" allows the M1 to also indicate the service identifier for in- coming calls so that the user what service is being used.

To ensure that all units involved in the call accept the call in the proper manner, the user should select the correct service using AT+FCLASS before accepting the call.
