I have recently finished redoing a voice evac system with 5 BSS PS8810C and 38 CTs-600 amps with PIP cards located in 5 different locations. The network is a fiber optic gigabit ring with 3Com switchers. All BSS units have V3.101 firmware and the PIPLite´s are v2.07. I am getting a load of audio dropouts on the receiving end of bundle 1 from BSS unit address and bundle 3 from BSS unit address I have checked and rechecked all addressing, and bundling numbering, and the problem persists. I am beginning to think that the problem may not be my programming, but the BSS PS8810C´s. I am not seeing the BSS units going offline or freezing. The other 3 units do not give me these errors.

Below are a couple of lines of info taken from a screen shot of the TCP/IQ Utility program.

Any input as to why this is happening would be very much appreciated.
