I have a MCD 5.0 pn an MXe with a LD T1 installed (not a PRI) every once in a while the the circuit is unavailable, each time i look and find that some of the channels are locked out. i busy and rts the channels locked out and all everything comes up. It seems to choose channels at random, there are no slips or errors on the circuit, i suspect that it is an issue with the provider, however the the telco says that there is no issue with the circuit, and with out any more specific info its a hard sell to them. I have 2 other PRI's that are working with out issue in the system and I have moved the circuit to a different Framer Module in the system that had a working PRI in it and had the same issue with the T1 circuit. i have looked through the software logs and found this entry shows up everytime a channel locks out:
trkhdlr_ logged invalid msg in locked_out PLID 15 1 3 20 Peripheral State: 001C, Data: 2A 0
any idea what that means?
