CPM -- Data / Bridge Talkgroup Setup
Now a legacy page

Once you have your c-Bridge peer on the Bridge CPM you will need to take a few steps to put the data and the voice onto your other managers.  Remember, no repeaters go onto a CPM.

There are 6 key pieces of information that you as a c-Bridge admin need from the upstream c-Bridge:

  • c-Bridge IP   (provided by Email to interested c-Bridge Admins)

  • CPM's UDP port   (provided by Email to interested c-Bridge Admins)

  • Authorization key   (provided by Email to interested c-Bridge Admins)

  • Data is on timeslot 1   (List of other CPMs)

  • Bridge TG on timeslot 2 and it uses TG ID 3100   (List of other CPMs)

Timeslot 1 and 2 can be reversed at your end.  You can change Data to timeslot 2 and the Bridge talkgroup to timeslot 1 if you wish if it fits in better with your talkgroup layout.


First, lets get the Bridge TG voice working. 

  • Using manager 47 as an example (DCI uses managers 50 and down for CPM's), Data is on Link ID 93 (manager 47, TS1) and the Bridge talkgroup is on Link ID 94 (manager 47, TS 2).

  • Go into Bridge Groups (Configuration/Audio Connections/Group Calling) and create an entry that looks like the this example below.  Change the site name to match your Control Center name.

Bridge Group
?
Site Name
?
Link
ID
?
Alert
on
Absent
?
Group ID
?
  • Go into your Super Groups for the Bridge TG if you already have a CC and idle your CC by turning it off but don't delete it yet.  This needed so you don't create a loop between the 2 c-Bridges.

  • If you have never carried the bridge TG, then you need to create a Super Group to manage this talkgroup. (This can be done with Bridge Group bindings only if you prefer)

  • Add the new Bridge Group above (example:  Bridge 94 CPM) into your Bridge Super Group.

  • If your Bridge Talkgroup Super Group is new then you need to bind your other managers into this Super Group if you wish to enable this Talkgroup.

  • You will now have TG 3100 going out on your Manager on timeslot 2.  If you wish to carry the Bridge on Timeslot 1, then substitute 93 for the 94 shown above to swap timeslots.


Second, lets get Data linked up.

  • Go into Bridge Groups (Configuration/Audio Connections/) and create an entry that looks like the this example below.  Change the site name to match your Control Center name.

Destination Name
?
Site Name
?
Link ID
?
Private Voice
?
Data
?
  • PVD means Private Voice / Data and it is on timeslot 1.  Leave both Private Voice and Data Checkmark enabled for now.  You can uncheck Private Voice here if you do not wish to supply Private Voice ANY manager on your c-Bridge but wait for now.

  • In the example below you see that binding 93 matches the editor sample above.  91 shows that Private Voice is disabled while 29 and 31 are enabled for Private Voice.  29, 31 and 91 are the better place to enable or disable Private Voice rather than at the CPM 93 if you wish to provide PV to some managers but not others.

Private Voice, Private+Group Data PVD TS1 T6-DCI 29 Pvt Voice Data
Private Voice, Private+Group Data PVD TS1 T6-DCI 31 Pvt Voice Data
Private Voice, Private+Group Data PVD TS1 T6-DCI 91   Data
Private Voice, Private+Group Data PVD TS1 T6-DCI 93 Pvt Voice Data
  • Data does not have Super Groups capabilities but you can create other Destination Names for Data to handle internally if you do not wish to have outside data mixed with your internal data.

  • Data may also be bound to both timeslots of any or all of your managers if you wish to have slot neutrality.  This is currently experimental as we have not yet done that across c-Bridges.  We also have not tested fully for adverse loading nor how active voice may adversely affect the opposite slot when bound to both timeslots.


Additional thoughts

  • Never bind any other talkgroups (only Bridge onto TS 2) to either timeslot of this CPM.

  • Once your CPM connected Bridge talkgroup is up and working satisfactorily, you may delete your Conference Connection if you have one idling.  You may wish to let it idle as it can be a diagnostic tool between c-Bridges if needed.  DCI will leave our CC to you in place...at least until we run out of CC's (100 max) unless you tell us you have deleted it at your end.  We would then delete ours.

  • If you wish to test data, we have some 7/24 radios that you can use.  Radio Checks are handy for end to end testing.  Participating Test Radios

  • We will be testing more and provide update in the Forum dealing with CPM's.

  • Hopefully the main USA talkgroups will get this CPM treatment once the Bridge CPM gets more c-Bridges peering in and we all get some time onboard to insure that it works well.

  • Your feedback is welcome in the forum so that everyone can benefit from your ideas.
