Cisco IPICS AND Motorola MTR 3000

[Boris Alban Cedric NZIMBOU KIMBEMBE]

Hi everybody ,

I have a Cisco IPICS  and I want to communicate with My radio station.

My Radio Controller is Motorola MTR 3000. I have My LMR RMS Router Configure and integarte int My Cisco IPICS.

Actually my issue its that i don't know how to configure Motorola MTR 3000  E&m Port .

Did  Some already configure Cisco IPICS with Motorola MTR 3000? 

your annwser will be helpfull

Hi Boris,

did you check SRND guide please ? There is chapter about LMR gateway interfacing and configuration.

http://www.cisco.com/c/en/us/td/docs/interoperability_systems/c_ipics/471/design/guide/sr471/sr471lmr.html

Basically, you have to find MIC, SPEAKER, PTT outputs/inputs on your radio, if you want to communicate through analog E&M card.

Hi Radim , 

Thanks for you answer and sorry cause i am replying late .

Actually de issue is that i can not see the E&m Port on the Motorolla MTR3000 .

I have a MIC card on the front of the MTR3000 could i use that as E&m Port ? 

Thx

Hi Boris,

I'm afraid MTR3000 doesn't have E&M port. I don't know radio's with E&M ports - it doesn't mean any such radios doesn't exists :-)

I found MTR3000 service manual for you. There are described front/back panel connectors. 

http://www.dhcom.fr/notices/Notice_EN_%20MTR3000_Install_and_User_Manual_DHCOM.pdf

You can't simply put straight RJ cable between E&M VIC port and MIC port on the MTR. 

Fortunately it looks that  guys in Motorola prepared necessary input/outputs on J7 connector.

Look at page 2-21. You can find there TX/RX audio pins, PTT pins.

I think you should look some radio guy nearby you, he can help you with E&M to MTR cable creation. Or, try to contact networkedradio as sadiqyusuf  wrote - in case you're not familiar with cable creation.

Just one note, maybe it will be helpful too. I attached simple schematics of the cable what I'm using to connect to analog radios (VHF/UHF).

first you need to get an interface cable from this site: http://networkedradio.com/ then the configuration, you can find a step by step from the SRND guide doc.

i have a GM-300 radio with the interface cable to the E&M port, i've done the config step by step but still can't establish a call between the IP-phones and the radio.  

[Radim Mutina]

Hi sadiqyusuf,

Did you try following test - dial into SIP phone integrated into IDC, then create Patch with Radio Channel or VTG (with your GM-300 radio) ? Or you were using IPICS phone service ?

Could you please describe what kind of tests did you do ? 

Radim

[sadiqyusuf]

yes i have two 7975 phone on a CUCM, integrated with the IPICS server, i have a cable connecting  the GM300 radio to the E&M port on my RMS. 

i can push a call from the DC to the IPphones but when i patch the radio channel, no signal.

[Radim Mutina]

Could you please describe more in detail what you mean with "no signal" ? In which direction ?

If you do PTT on IDC, could you speak to radio ? Did you hear signal from radio on IDC  ?

Things to verify:

1. LMR gateway config

2. cable between radio and gateway

3. multicast routing 

Could you please post your LMR gateway config here ?

I'm also adding some useful commands to check E&M/radio connection.

LMR_gateway#test voice port 0/2/0 inject-tone network 1000 

LMR_gateway#test voice port 0/2/0 inject-tone network disable

- this will verify if your LMR gateway is sending multicast in case there is an audio-in signal at E&M

LMR_gateway#test voice port 0/2/0 inject-tone local  1000    

LMR_gateway#test voice port 0/2/0 relay e-lead on        ! E-lead is connected to PTT, so we do PTT ON

LMR_gateway#test voice port 0/2/0 relay e-lead disable  ! PTT OFF

LMR_gateway#test voice port 0/2/0 inject-tone local disable

You can use also debug vpm all to check LMR signaling at E&M.

i can send voice signal from the IDC to the phones, but i can't reach radio. i will try the commands......find attached the config on my RMS.

[Radim Mutina]

After quick look at your config, I can't see ip pim sparse-dense-mode commands in Vif1 and Gi0/0 interfaces. 

[sadiqyusuf]

Hello Radim,

thanks for your observation, i have added the ip pim sparse-dense-mode commands in Vif1 and Gi0/0 interfaces. i also want to know before i test with the added config.........where am i suppose to configure multicast? on my access switch or the RMS. thank you.

Are you using a donor radio to access the channel you are using?  what model radio?
