One the Orion/7100 enclosures you setup SG functions to map the tones to assign System/Groups.

Yes, I'm aware of that. However, the mapping of the programmed talkgroup to a specific tone for the tone remote system is done on the 5 tone board which MAY be programmable but NOT via RPM or ProGrammer, and I was never asked to investigate the possibility of reprogramming that board.
(I just looked up the manual and the 5 tone board's tone selections are hard coded.) They are:
SF1 1950 Hz EIA for channel 1
SF2 1850 Hz EIA for channel 2
SF3 1350 Hz EIA for channel 7
SF4 1250 Hz EIA for channel 8
SF5 1050 Hz EIA for channel 10
The issue at hand is that the customer is using Telex C1212 consoles which control four or five separate radios via tone remote. One limitation of the C1212 is that while you can edit the tone to be used to control a given selected channel, this edit is global and is the same across all six channel circuits.
You simply can NOT program this kind of console so that it sends tones 1, 2, 3, 4, and 5 to the radio plugged into line 1, and have it send tones 1, 2, 7,8, and 10 to the radio plugged into line 2. All lines have to use the same tone arrangement.
The other half of the puzzle is that the Telex consoles run an Orion (consolette) on line 1, another on line 2, and lines 3, 4, and 5 are all connected to Motorola UHF radios. Which are all programmed for anywhere from 1 to 5 channels per radio and they all have to work as per the county's radio plan documents.
Those Motorola radios are programmed with their operating channels as channels 1 thru 5 in regular consecutive order.
The problem crops up if you attempt to access the third, fourth, or fifth channel in the UHF radios.
The Telex consoles are not able to send the correct set of tones to the UHF radios (tones 1, 2, 3, 4, and 5) if they are programmed to correctly access the 5 talkgroups in the Orion consoles, since the tone board in the Orion consoles is programmed for tones 1, 2, 7, 8, and 10.
There's a fundamental incompatibility here. Either the Telex console is programmed to operate the Orions properly, OR it's programmed to operate the UHF Motorolas properly. It can't do both.
Not unless the 5 tone board in the Orion consoles can be reprogrammed to utilize the industry standard EIA tones for the first 5 channels. Which I don't even know if it's possible.
Alternatively, the UHF radios could be programmed up with extra dummy channels with the correct channels being assigned to slots 1, 2, 7, 8, and 10. Which sounds easy but some of the radios in use are only basic 4 channel radios. So, swap radios. It gets annoying.
