Interop Connections

What are Interop Connections?

Interop Connection is a special type of user, which facilitates communication between Land Mobile Radio (LMR) and Broadband Direct Connect (DIRECT CONNECT) networks. These users are restrictive and corporate admin cannot assign any contacts to these users. Because of this limitation, the assign contacts and assign user sets buttons are disabled. In addition, these users can be members of only one TalkGroup. The addition of Interop users to more than one TalkGroup is not allowed.

There are the following types of Interop Connection users:

  • LMR User: These connections are used for one-to-one communication during P25 interoperability.
  • LMR TalkGroup: Provides link between Broadband DIRECT CONNECT TalkGroup and LMR TalkGroup during an Interop call.

You can assign LMR User as a contact to a Broadband DIRECT CONNECT user for one-to-one communication. The LMR User name assigned by you is the talker identity during those calls. You cannot add LMR User to a Broadband DIRECT CONNECT TalkGroup.

You can link LMR TalkGroup to only one Broadband DIRECT CONNECT TalkGroup. The talker identity during the Group Connect uses the LMR TalkGroup name that you assign. To communicate on an Interop call, a Broadband DIRECT CONNECT user must have Interop User MRC feature provisioned from the Billing Interface. There is a special icon display for the DIRECT CONNECT user when the feature is provisioned. You can add a user without Interop User MRC feature in a linked Broadband DIRECT CONNECT Group, however, the Interop call is not connected to a DIRECT CONNECT user unless Interop User MRC feature is provisioned for the user.

Create an Interop TalkGroup

  1. Select TalkGroups, then choose Create TalkGroup.
  2. Choose Standard as the TalkGroup Type.
  3. Enter the name of the TalkGroup and select an avatar.
  4. Choose Assign Members and assign members. The TalkGroup automatically changes to Interop when at least one Interop is added.
  5. Select Create, then select OK.
