– reduced audio delay for a console PTT
– consoles may pre-empt Causeway patches and Causeway
simulselects
– patch/simulselect update time is minimized when a trunked
radio roams/logs into a new trunked site
– eliminates the single-point-of-failure (MOM Controller Board)
experienced with "soft" patches and simulselects
– frees-up patch/simulselects at consoles which were previously
used for "soft" patch/simulselect of these GIDs and
conventional channels
All Causeway patches and Causeway simulselects are configured from
the
Conventional Channel Configuration dialog box, Figure 35.
Each channel is configurable for either Causeway patch operation,
Causeway simulselect operation or no Causeway operation. If either
Causeway operation is selected, the GID number to patch/simulselect to
must also be entered.
Disabling (undoing) a Causeway patch or a Causeway simulselect after
it has been programmed can only be accomplished from the
Conventional Channel Configuration dialog box, not a console. To
disable Causeway patch or Causeway simulselect operation, enter the
Conventional Channel Configuration dialog box, select the
appropriate conventional channel, select "None" in the Causeway
group, and send the new configuration. Saving the new configuration is
done automatically on a send.
Causeway Patch Operation
Causeway patch operation is summarized as follows:
– A conventional site-originated call on a Causeway-patched
conventional channel is routed to consoles and trunked sites
via the trunked Group ID (GID) assigned to the Causeway
patch.
– A trunked site-originated group call is routed to consoles and
the Causeway-patched conventional channel via the trunked
Group ID (GID) assigned to the Causeway patch.
– A console-originated group call is routed to trunked sites and
the Causeway-patched conventional channel via the trunked
Group ID (GID) assigned to the Causeway patch.
