CALL BIT Screen
[] Active
When lit, the Active annunciator indicates that the control channel of the Test
Set is turned on. If this annunciator is lit the base station is transmitting system
parameter overhead messages on the assigned control channel. If the annunciator
is not lit the base station is not active (note that the Test Set may still be outputting
a modulated RF carrier but the Test Set’s firmware is not active and no
communication can occur between a mobile station and the Test Set).
[] Connect
When lit, the Connect annunciator indicates that the mobile station is connected
to the Test Set on a voice channel.
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 uses the messaging
protocol as defined in the applicable industry standard.
