Selects the ISDN termination side.

[0] User side = ISDN User Termination Equipment (TE) side
(default)

[1] Network side = ISDN Network Termination (NT) side
Note: Select 'User side' when the PSTN or PBX side is configured
as 'Network side' and vice versa. If you don't know the device's
ISDN PRI termination side, choose 'User side'. If the D-channel
alarm is indicated, choose 'Network Side'.
Same as the description for parameter TerminationSide, but for a
specific trunk ID (where x denotes the Trunk ID and 0 is the first
Trunk).
Determines the ISDN B-Channel negotiation mode.

[0] Preferred.

[1] Exclusive (default).

[2] Any.
Notes:

This parameter is applicable only to ISDN protocols.

For some ISDN variants, when 'Any' (2) is selected, the SETUP
message excludes the Channel Identification IE.

The 'Any' (2) option is applicable only if the following conditions
are fulfilled:

The parameter TerminationSide is set to 0 ('User side').

The PSTN protocol type (ProtocolType) is configured as
Euro ISDN.
Indicates the NFAS group number (NFAS member) for the selected
trunk.
'x' identifies the Trunk ID.

0 = Non-NFAS trunk (default)

Trunks that belong to the same NFAS group have the same
number.
With ISDN Non-Facility Associated Signaling you can use single D-
channel to control multiple PRI interfaces.
