Talk-Group Rewrite was conceived as a way of making talk-groups behave more
|
|
like the reflector system and of attempting to solve the problem of "slot
|
|
contention",where the user may be locked out of a slot by traffic on a
|
|
talk-group they know nothing about, without knowing why. This is frustrating to
|
|
users, both those new to DMR and seasoned DMR users.
|
|
|
|
TG Rewrite, when enabled for a slot, rewrites the DST ID of incoming talkgroup
|
|
traffic to TG9, alowing audio to be heard by any user monitoring TG9 on that
|
|
slot. If the user then replies on TG9, as long as they key-up during the
|
|
CallHang period, the DST ID (TG) is again rewritten on the outbound traffic,
|
|
which transparently maps back to the originating talkgroup.
|
|
|
|
To use a User Activated talk-group, briefly key-up on that talk-group to
|
|
activate it, then switch back to TG9 and talk as normal. If the CallHang period
|
|
expires, you may need to activate the talk-group again by keying up on that
|
|
talkgroup briefly, as before.
|
|
|
|
It is useful to set the CallHang parameter to a generous amount. I am currently
|
|
using seven seconds.
|
|
|
|
|
|
Two boolean configuration options control the TG Rewrite feature:
|
|
|
|
TGRewriteSlot1=[0|1]
|
|
TGRewriteSlot2=[0|1]
|
|
|
|
ACL's are applied before the rewrite, so still apply to rewritten traffic on
|
|
original (non-rewritten) talk-group.
