HAND-BACK MOBILE POWER LEVEL DTC – (Thresholds and Power Control
Menu)
Default: 2, Range: 0-16
This setting is the DMAC attenuation code that will be used for calls that are handed
back to the donor. This should be set to the same as is being used for the donor cell.
Level 2 represents a maximum size cell, assuming a predominance of subscriber units.
DELAY BETWEEN HANDIN ATTEMPTS – DTC – (Thresholds and Power
Control Menu)
Default: 5, Range: 0 to 250 seconds
This setting establishes the minimum time waited after a hand-in attempt is made
before another will be attempted. The EAC uses the MAHO RSSI reported by the
portable and the RSSI that it is measuring from the subscriber to calculate if the
subscriber should be better served by the EAC. If so, the EAC will do a hand-in
attempt. However, not all hand-in attempts are successful. Sometimes, the EAC
transmits the handoff message to a subscriber, but the subscriber unit does not respond.
This may be because of errors, but most often, it is because the signal level from the
donor is still on the order of the signal level from the EAC. This causes no problem; the
call continues on the donor. In fact, this represents the desired outcome, since the EAC
DTC resources will be left free to handle calls that only it can cover. This time delay
parameter sets a limit on how often the EAC will attempt to hand-in a call that is
operating on the donor.
6.9 SCS command support for DTC operation
The SCS (Show Call Status) command has been changed to show per slot activity for
TDMA channels. The possible reasons for DTC call starts are the same as with analog
- mobile originate, mobile answer or RSSI > Threshold. New reasons are added to
indicate why calls end on DTC channels. Note that for each of the reasons, there is
associated DCS call statistic maintained. The possible DTC call end reasons reported
are as follows.
MOBILE RELEASE DETECTED – This indicates that a mobile initiated release was
detected.
DONOR RELEASE DETECTED – This indicates that a land side initiated release was
detected. Note that calls that end due to this reason and to MOBILE RELEASE
DETECTED are summed together into a single RELEASE DETECTED statistic.
