XTS-5000 pin out to CEB

Post by Sierra_5 »

I am trying to connect an XTS-5000 to the CEB using a Remote Speaker/MIC cable NMN6191. I want to control the PTT and Audio functions at the Gold Elite Console. I have the pinout guide for the handset but cannot find one for the CEB. Any assistance would be appreciated.

Don't mean to be a pain - but why on earth would you want to do this?

Also, i think what you would have to do is have a tone control card (what part number your using would probably help the centracom guru's)...

A Tone remote adapter.

Then, i'm sure you could redirect the audio, tx, etc. However, it would probably take some audio balancing to get it to sound right....

XTS-5000 to CEB

Post by Sierra_5 »

Temporary Solution to the following problem,

New M/A-COM fixed infrustructure.

Big Fleet of XTS/XTL-5000.

Old System has been using DES-XL and OFB for long time.

M/A-COM has no OFB encryption on console at this time, boses will not turn off encryption, running three XTL-5000 thru CEB to use trunked system, have no more Tone Remotes, have XTS-5000 however. Don't want to spend any additional money.

You will require some sort of tone remote interface box between your CEB & the XTS5000, so more money is needed.

The card you use in the CEB is called a BIM...Base Interface Module. It talks to the radio with either 2-wire or 4-wire tone control. Thus the need for the tone remote interface box.

There are a few different ways to interface to the BIM card. If you're lucky, there is an 8-port RJ-45 strip, usually located at the top of the card cage rack. This connects to the card cage backplane via two 25-pair connectors & breaks out each BIM card to pins 1 & 2 and 4 & 5 in the RJ-45 connectors. In this scenario, you simply wire the RJ-45 to the tone remote box RJ-11 & away you go.

If you don't have that RJ-45 strip, then you need to wire the 25-pair connector(s) on the backplane to one of those big ol' ugly telco punchblocks that can accomodate the 25-pair cable. This breaks out the BIM card to specific pairs on the punchblock, though I don't have that info right in front of me.

A BIM with an AUX I card could do E & M keying but he'd still need to build an interface to go from balanced to unbalanced audio for rx & tx. The tone remote adapter is still the easiest way with a tone keying BIM as others have mentioned.

The BIM is a transformer input, so you really don't need to convert the radio to balanced output .
