Another thought, You don't have the "timing cable" hooked up in the third cab, do you?

It is ONLY required on the FIRST T-1 card(an old myth was that you needed to daisy chain them all together) in and out etc. to the EVCM card
</font>
Could THIS be the source of that 'old myth?'

Quote
<font face="Verdana, Arial" size="2">From IDS Manual Issue F (pg610-49)
a. If the T1 circuit is connected to a Central Office, connect the thin coax receive clock recovery cable (p/n 02027–1) between the SMB coax connector J2 on the T1 card and J6 on the EVCM. If more than one T1 card is to be installed, the receive clock recovery cables are chained between the cards and then to the EVCM. Connect J2 T1 clock out of the T1 card furthest from the EVCM to J1 T1 card clock in of the next T1 card, and so on until a connection is made to the EVCM. See Figure 45.</font>

I do have a clock recovery cable from the EVCM in Cab3 to that T1 card in Cab3 (which may be unecessary, as the manual does state to not do it in Cab2), but I am NOT spanning cabinets with a huge clock recovery cable loop.

Turns out that I was able to get my provider to change the line to GS+AF (from LS) and THIS time it seems to be working correctly. We're now testing on a "live" line rather than my test line, but it seems to be the road to solving this problem...

Problem solved... changing to Ground Start with answer supervision and enabling the feature "Cutoff on Disconnect" alleviated the issues.
