Enable D64S Mode
D64S mode is a mode for using ISDN B-channel(s) 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, enable the D64S mode parameter, and make sure the TEI parameter is set to 255.
This means that for any application that uses ISDN (such as. PPP) the application uses D64S
mode.
First D64S B-channel
When using D64S mode, there is no dialing protocol to negotiate which B-channel to use. This
must therefore be specified using this parameter. Check the B1 radio button to select channel
B1. Check the B2 radio button to select channel B2 (if another channel is requested from an
application then it will use the other unused B channel).
3. Click Apply.
