Zone 1 has taken another step in the ongoing increase in technology. As of the February 14th nodelist, the Zone 1 ISDN flags have been changed to comply with FSC-0091. There will be a 1 month grace period during which either old or new flags will be valid, after which only the new flags will be used.

;S
;S U flags for ISDN nodes;
;S
;S Nodelist  Specification of minimal support required for this flag
;
;S Flag any additional support to be arranged via agreement between
users
;S ===================================================================
;S V110L   ITU-T V.110 19k2 async ('low').
;S V110H   ITU-T V.110 38k4 async ('high').
;S V120L   ITU-T V.120 56k async, layer 2 framesize 259, window 7,
                                  modulo 8.
;S V120H   ITU-T V.120 64k async, layer 2 framesize 259, window 7,
                                  modulo 8.
;S X75       ITU-T X.75 SLP (single link procedure) with 64kbit/s B
                                                    channel;
;S           layer 2 max.framesize 2048, window 2, non-ext.mode
                                         (modulo 8);
;S           layer 3 transparent (no packet layer).
;S ISDN      Other configurations. Use *only* if none of the above
             fits.
;S ===================================================================
;S NOTE: No flag implies another. Each capability MUST be specifically
         listed
;S If no modem connects are supported, the nodelist speed field should
be 300
;S
;S Conversion from old to new ISDN capability flags:
;S - Nodes in the USA currently use the 'ISDN' flag.
;S   Most will be able to change to V120H (64k lines).
;S   Also many to V120L,V120H (64k lines) with autodetecting
     equipment.
;S   Some to only V120L (still with 56k lines).
;S - Nodes in Europe currently use the ISDNA, ISDNB and ISDNC flags.
;S   A simple translation will do the trick here.
;S   ISDNA -> V110L
;S   ISDNB -> V110H
;S   ISDNC -> X75
;S
;S ===================================================================
