Dave,
      Thanks for the memo, it is useful to get feedback on how users see the
network.  It is, however, difficult to answer all the points as all the
documentation is no longer available after this period of time.  It is
important that users tell operations about problems while they are 
happening, not long after the event.

   I have done as much checking as is possible and have come to the
following conclusions:
   
   1) The Central Area CPSE had a harware fault that caused the problems
      on the 4th and 6th of February.  This machine has in fact been 
      reasonable reliable and that period can be seen as very exceptional.

   2) At least two of the faults described as 'XCALL Down' were in fact
      caused by the Vax being down, or not responding.  

   3) February was a very bad month from the Vax User's point of view and there
      were repeated problems until faulty h/w, both in the Vax & its network
      connection was isolated and removed.

   4) There is no trace at all in the logs for the entries described as
      'XCALL Break'.  This fault in particular we need to know about as soon
      as it happens.

While I realise that Mike is not really concerned with whether a fault is in
the Vax or in the network, I am confident that February was an exception.
