CALL CONTROL Screen After a Successful Origination
The TIA/EIA-136 specification indicates that on any single RF channel, the
DVCC for all slots must be the same. For example, if your DCCH is assigned to
channel 42, and you assign the mobile to a DTC of 42, then the DVCC for both
the DCCH and the DTC must be the same.
Additionally, the specification requires that the DTC, if assigned on the same
channel, be assigned to a different slot than the DCCH. The Test Set always
assigns the DCCH to slots 1 and 4. If you assign your DTC to the same channel
number, and assign the DTC to slot 1 or 4, the Test Set will remain in the Access
state when you attempt to originate or handoff.
Select
again to return the Test Set to the Active state. You must then

change settings of the DVCC, slot, or channel numbers in order to prevent this
from re-occurring.
What you should do:
•
Don't use the same RF channel number for both DCCH and DTC.
•
If you need to use the same RF channel number for both, then verify that the
