Do not deactivate the LAPD session
This parameter ensures the unit will not deactivate the LAPD session when an X.25 PAD
session is terminated.
Enable D64S Mode
D64S mode is a mode in which ISDN B-channel(s) may be used without the need to use any
D channel protocol. It is sometimes referred to as “nailed up” ISDN. To enable this mode for
this LAPD instance, Tick the D64S mode parameter checkbox and ensure that the TEI
parameter is set to 255. This means that for any application that uses ISDN (e.g. PPP) then
it will use D64S mode.
First D64S B-channel
When using D64S mode there is no dialling protocol to negotiate which B-channel to use.
This must therefore be specified using this parameter. Check B1 radio button to select
channel B1 and Check B2 radio button to select channel B2 (if another channel is
requested from an application then it will use the other unused B channel).
