Have a question about this module. Is this the interface between the console and the radio? Still trying to understand what everything does for these systems to get a better understanding of them.

Thanks, Ryan

looks like a centracom 1 interface of some kind although I have not seen quite that configeration. It appears to be using spectra-tac shelves.
The way I see it (and this is a guess from spectra-tac days) is that there will be a DC loop lo the chassis and the chassis then generates the keyup tones for remote or even local stations.

This unit is really old as centracom II with the CEB appeared in 87.

This is a tone priority/control unit for SpectraTAC voting systems. It allows the console to have priority over the mobile units.

It also contains a command module and a tone keying module.

This appears to be an SP unit, as these modules are generally contained the same chassis as the Signal Quality modules.

I'd wager that the customer originally ordered this as an SP product, and that the associated racks with this stuff were filled to capacity with Signal Quality modules, and the rest of the cards were placed in a separate rack - this one.

It's also possible it's an old SpectraTAC system out of a trunking environment, I believe that trunking voting using SpectraTAC broke the console priority equipment out in separage card cages like this.

Could be just a voter from which someone glommed the SQMs. (Been known to happen when stuff is taken out of service.)

The label on the lowest unit, however, suggests that the system from which this came had multiple paralleled consoles or remotes, and the "extra" remotes were tied into the SpectraTac system via their own chassis (with own TKM and TPM). Reason for this might have been that SpectraTac's seem to be sensitive to overloading, so each separate remote line got its own independent input.
