The phone line between the SX-50 console and the main control is disconnected or the console may need to be rebooted (unplug the phone line then reconnect it). If this doesn't solve it then contact your PBX system support person.
The coils on your PBX need tuned. These coils need to be on a regular maintenance schedule so that they are impedance-matched to the telephone company's equipment (their line cards). The incoming call causes the telco's line card to try to adjust its impedance to your PBX's out-of-tune coils, and you get access to outside lines for awhile, but the telco's line card tends to return to the impedance specs that it "knows" is correct, and when that happens, your PBX loses access to outside lines until you (or a customer) calls into the PBX from an outside line.
The 25-pair Amphenol connector is just something the industry uses because it's standard and easy. In a TDA system, the 8-port C.O. Trunk card uses the first 8 pairs, a 16-port the first 16 pairs, an 8-port Pana station card uses the first 24 pairs, 3 pairs per extension. The last pars don't have any hardware behind it and are connected to nothing.
The only phone system that I remember where all 25 pairs are used is a 1a2 10 button set and, maybe a Comdial system where the 25th pair is the common audible for station 17 :-)
You are using the wrong option for transfer -- the one you are using is a conference which requires the person transferring the call to stay on the line. You need the option which permits a blind transfer or announced transfer. This issue is specifically discussed in the manual.
