 The initial config of the switch is useless for our application, so the easiest thing is to delete it straight away. Unfortunately, unlike Cisco IOS there is no command line repeat, but the later firmware images have command completion and help at any point by typing a "?".

 Set the atm network prefix and switch number (Don't use my numbers, they have to match the existing atm numbering hierachy in use). Depending on your atm network mask (pglevel in FVC speak), your ilmi netprefix may be longer or shorter than this. The .05 at the end is the switch id.

 HDB3 is "High Density Bipolar 3zero substitution", an alternative to AMI etc. This has to match the line encoding being used by the circuit provider.
