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. Rewrite is also
enabled if an outbound call is made to a talkgroup and then TG9 is activated
during the CallHang period.
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. Alternatively, you can wait for inbound audio to
re-activate the rewrite, then respond during the CallHang period.
Note, proper ettiquette dictates that the user confirms the repeater is free
before activiating this feature. It is best to ensure the slot is keyed from
"cold" when activating a talkgroup for rewrite. Although not strictly
neccesary, it may be advantageous to also disconnect the repeater from the
reflector system first, if using slot 2.
Talk-group rewrite was originally intended to work with User-Activated talk
groups, although it will function with permanent talk-groups too.
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.
