Radio Gateway

[k0pwo]

Hello to the group.

I am posting my question here hoping that someone in the group might be able to point me in a good direction.

I am with an IMT Type 3 group and we are looking for a Radio Gateway Solution. Our goal is to be able to cross connect a couple of different radio systems together using portables or mobile radios. Primarily it will be to connect a conventional DMR or analog channel to a P25 talkgroup. The system does not need to be elaborate. We have look at the Base Camp Connect system which heading in the right direction, but still out of our budget. I am quite aware that most of these systems are costly.

This is why I am coming to the group to possibly give me some additional thoughts or suggestions of what is out there.

Any assistance would be appreciated.

Thank you...

David

ACU-1000

ACU-1000 | JPS Interoperability Solutions | Leaders in RoIP

The ACU-1000 is an industry-defining communications gateway that connects disparate radio systems, SIP telephony, and RoIP devices.

The gold standard.

+1. Or ACU-T. If you deploy it with a computer you can use premade config files so you are ready to go for the various modes, such as adding the delay to wait for PTT grant on trunking systems.

Low budget and interoperability, not a good combination. And IMT should have funding to do this right.

All I can say is stay away from the ham radio stuff.
+1 on ACU. JPS stands behind their stuff and will look after you. It'll cost more, but it'll be worth every penny. Also, make sure all the radios are well separated so you do get desense and things locking up. You don't want to be the guy the COM-T or COM-L finds is screwing up their radio system.

Thank you all for your responses. Rest assured this isn't a "ham radio" build at all. I wasn't aware of the ACU-T option. We are looking at that now as well.

Thank you again...

If your team is part of the state, they should have resources/technical help to assist. In fact, I'd be really surprised if they didn't already have a bunch of ACU's kicking around. I know we have them all over the place in California.

We have the ACU-M. Its basic and was reasonably priced. I liked it because all settings can be done in the box vs having a PC.

As others have said, ACU-1000, ACU-M and other related products would work. Also, if that P25 system already uses GGM800 Conventional Channel Gate Way (CCGW) device, virtually any IP interface could be used, such as Zetron IP 6301/6302 (single or dual link), M4x IP interfaces, even old Telex IP-223/224 interfaces, allowing a DMR donor radio to connect local DMR users audio into a P25 system. Look for a vendor that is used to setting up Radio Over Internet Protocol (RoIP) links, and supporting IP interface devices.

Connecting DMR with P25 is becoming a lot more common with IP interface devices into P25 infrastructure. Once the audio is IP, all of the Base Camp systems on their website look like they could do this on a basic level.

Look at ICRI as well.

We have a fleet of ICRI's and while the ACU is an excellent product, nothing can beat the ICRI for quick deployment and "so easy a caveman could do it" connection/setup. No classes needed and I've trained dispatchers to set them up. No PC setup, software or complex configurations either. They ain't cheap but support from C-AT is superb and they are QUALITY built. I have had one deployed for a YEAR supporting COVID-19 response and just de-mob'ed her yesterday and put it back in my truck for the next crisis! (if you want to discuss offline, PM me for my contact and I'll be glad to discuss or give you a facetime demo of how quick an ICRI can be setup and deployed)

 

[Mr_Boh]

ICRIs are fine, and they are quick, but given the choice I would pick an ACU 100 times over (and it's something people will disagree with me on and I get it). Yes, C-AT support is good, but to the point of "so esay a caveman can do it" I have seen it get folks into trouble. Slightly different set of considerations than an ACU. Have also had audio quality issues/interference issues here and there - C-AT quick to address, but still frustrating.

Reference computer setup - it certaintly is preferred for ACU, but you can configure even the ACU-T with the dialpad. It's easy to throw a field guide for config with it. The ACU-M is certainly more user-friendly. But yeah, the ICRI needs none of that - plug in your radios, select a net if you have that verison, and you are off to the races. The cord reels are also a really nice feature of theirs with the little portable radio velcro.

JPS has a new series of RoIP gateways that are two port and use distributed IP backhaul. Sort of like the Telex IP223/224 series, but with clearly an expanded set of capabilities. I am curious what others think about this product.

I know some that are using it and are quite happy with it.

Big part of it is that JPS supports the users pretty well.

We used to use the NXU-2A when our system was TDM-based, then the ARA-1 when we went to SIP. We connect our 200 or so radios to our PBX via SIP. JPS let us demo their new RSP-Z2 and it simply wouldn't make the SIP connection to our PBX.

We're currently in love with the the Cubic/Vocality RoIP device. https://www.vocality.com/vocality-roip It works on just about any radio without finicky audio adjusting. It's tolerant of sub-par networks. Heck, you can even get a model with a built-in LTE modem.

The ACU-M is very simple also. All our SAR team was trained on it. No PC required, hook up radio push button and done.
