Data Spec

This field is used to determine how the contents of the signaling messages are built.

•Std = Use the signaling formats defined in the applicable industry standard to build the forward control channel and forward voice channel signaling messages. Use the contents of the applicable fields on the CALL CONTROL screen and the CALL CONFIGURE screen to obtain information necessary to build the messages. Whenever a signaling message is used, update the contents of all fields in that message on the CALL BIT screen.

•Bits = Use the bit patterns as set on the CALL BIT screen to build all forward control channel and forward voice channel signaling messages. For any call processing function (that is, setting the message stream on the active control channel, registering the mobile station, paging the mobile station, handing off the mobile station or releasing the mobile station) the user is responsible for setting the contents of all signaling messages used in that function. The Call Processing Subsystem host firmware uses the messaging protocol as defined in the applicable industry standard.

NOTE:The contents of the applicable fields on the CALL CONTROL screen and the CALL CONFIGURE screen are not updated to reflect any changes made while in the Bits mode. There is no coupling between the Bits mode and the Test Set. For example: if a mobile station was actively connected to the Test Set on a voice channel and the user changed the CHAN field on the forward voice channel mobile station control message (FVC V Mes) and sent that message to the mobile station, the mobile station would change its voice channel assignment. However, the Test Set will stay on the voice channel assignment specified in the Chan:field on the CALL CONTROL screen. This situation will result in a dropped call. The Bits mode should not be used to change any parameter that can be set on any other Call Processing Subsystem screen.

The :DSPecifier command is used to control this field.

The query form of the command (that is, :DSPecifier?) can be used to determine which method is currently being used to build the contents of the signaling messages.

See "Reading the CALL BIT Screen Message Fields" on page 91 for information on

how to read the contents of the individual messages.
