Frequently Asked Questions

Q: Can I use a simplex MMDVM hotspot on the network?

A: No, all hotspots must be Duplex models in order to be compatible.

Q: Can I use the network without a hotspot?

A: Yes, we support access via Wave5000 in case a radio is inaccessible. For the best experience, we encourage users to communicate with a P25 radio connected to a hotspot or wider site; however, we are expanding our non-RF options to access over IP.

Q: Can I share my ID's with friends?
A:  Users may temporarily share radios containing their assigned IDs with friends, co-workers, and family for use on their own talkgroups. However, the actual sharing of IDs to be provisioned unto radios which are not the sole property of the registering subscriber is prohibited. Each radio shall have (1) uniquely assigned Radio ID issued by Network Operations & Tek Support.

Q: Can encryption be used?

A: Encryption is permitted, and actively in use. Many of our public talkgroups allow encryption use with a specific key; however, there are regional and use-case restrictions which may prevent encryption on one or more talkgroups. Please see the system talkgroups list for more information regarding encryption application throughout the network.

Q: Is P25 Phase II supported?

A: No. Phase II or P25 TDMA operation is unsupported on hotspot sites due to hardware limitations. Phase II is operational on select wide-area sites.

Q: Is Link Layer Authentication or Radio Authentication in use?

A: LLA/RA is currently enabled on the system on both DVM and Astro systems. For DVM it is site by site and needs to be enabled by the site owner. On the Astro system in use for  select Wide Area sites LLA is enabled on a Radio ID by Radio ID basis.

Q: Is TMS supported?
A: Motorola Text Messaging Service is supported over conventional mode only via a Unit-to-Unit (U2U) configuration. This may change as we continue to add more features.

Q: Is *insert Motorola proprietary feature here* supported on DVM sites?
A: No proprietary features from ANY manufacturers are supported. CTRS operates on a Common-Air Interface so that vendor exclusions are eliminated, therefore permitting greater entry opportunity for a user's'choice of radio manufacturer.

Q: Is *insert Motorola proprietary feature here* supported on Wide Area sites?
A: Yes. *Most* Motorola Proprietary features and *some* EF Johnson data features are supported on select wide area sites.

Q: Can I use a Quantar or GTR with the system?
A: Yes Quantar, STR3000, GTR, and DBR M series sites are supported on the system in Full Phase 1 and/or Phase 2 operation with data support.
