Set to 200 ms more than MDC
‘System Pretime’ programmed in
PSU.
If set to 390 ms or less, the VR will
wait for MDC signaling to be
decoded before proceeding. If
MDC is decoded VR will proceed
accordingly (initiate call,
emergency handling, etc.).
If set to 400 ms or more, the VR
ignores PSU emergency retries for
the duration of the timer to allow
proper processing of a decoded
MDC1200 emergency to the
system and sending of emergency
Ack to the PSU.
If the PSU MDC ‘System
Pretime’ is set to 50ms,
this field should be
programmed as 250ms.
If the PSU MDC ‘System
Pretime’ is set to 700 to
800ms, this field should be
programmed as 1000ms.
MSU Mode
Steering
Hang Time
When programmed to 0, the MSU
stays on the steered mode after the
PSU inbound call is over.
If programmed to >0, the VR forces
the MSU to return to the original
MSU mode when the PSU inbound
call ends and the programmed
timer expires.
Applicable when Steering
is Enabled.
Refer to Functional
Description ‘Mobile Mode
Steering via PL/DPL’
section for further details.
