Why will the routers not route or connect over the WAN link?
You will need to determine if the router is behaving properly. Check the statistics screen for circuit statistics. If you have Transmit (Tx) or Receive (Rx) errors at less than a one percent rate, the link is probably good. DSU/CSU or Modem clock settings are a common problem. Our router by default is always looking for clock from the DCE which in turn should normally get clock from the telco. Framing problems are common on T1 type circuits. Our router does not care what the framing is, but of course if it is not set properly on the DSU/CSU, matching the T1 service, then bad frames will result. The event log, accessed by the main menu or by typing “log” at the NCL prompt, can give you an indication of the current connection state of the routers across the WAN.
