INIT = initialization string
The chart above is used for connecting to a terminal adapter or other
ISDN device, a remote server, online service, corporate LAN, or PC.
Note 1
If your ISDN service provides 56 Kbps rather than 64 Kbps
per B channel, you must add
%A4=1
to the above
initialization strings. The default setting of
%A4=1
configures the device for operation with lines that provide
64 Kbps per channel.
Note 2
The connection may use V.110, V.120, X.75, ML-PPP
(Multilink Point-to-Point Protocol) or PPP (Point-to-Point).
ML-PPP provides the highest speeds (128 or 112 Kbps) but
generally at a higher cost. PPP is less expensive but with a
slower speed of 64 or 56 Kbps. V.110 is used primarily for
connections to Japan and Europe, and V.120 is used to
connect to some BBSs, ISPs, and remote servers with ISDN
lines.
Note 3
The
%B
n
command forces the TA/V.34 or TA to higher
than usual port speeds, which are particularly recommended
for ML-PPP. Use
%B38
to force connection at 230.4 Kbps,
or
%B39
to force connection at 460.8 Kbps.
