The ONcorehub/CELLplex 4000 error-log is full of messages like 'Invalid Message Length'.The WAN (public network providing the VP-tunnel) uses the VCI=5 for its ownpurposes, and there is a conflict with the ONcore hub/CELLplex 4000 which alsouses VCI=5 (ATM-Forum Signalling VCI).Steps to Take:1. Ask your public network provider if they use the VCI=5. If necessary, put an ATMdevice between the WAN and the ONcore hub/CELLplex 4000 to do the translationof Signalling VCI to a value other than 5.7-42 ONcore ATM Switch/Control Module: Installation and User's Guide
