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