Introduction
The H320 configuration
xConfiguration H320 NetType
Defines the network type to use for H.320 calls.
Value space:
<BRI/PRI/External/G703>
BRI: Select BRI for the BRI network.
PRI: Select PRI for the PRI network.
External: Select External for the external network (Net/V.35).
G703: For test purpose only.
Example:
xConfiguration H320 NetType: BRI
xConfiguration H320 Bonding Timer
Relaxed bonding timer is used when B channels requires additional time before they can become
transparent.
<Normal/Relaxed>
Value space:
Normal: The default value is Normal.
Relaxed: Relaxed bonding timing should be used with applications where the B channels use
some additional time before they become transparent, like external encryption devices etc.
Example:
xConfiguration H320 Bonding Timer: Normal
xConfiguration H320 Bonding Rebonding
Rebonding is used to re-establish H.320 calls if corrupted data is received for a longer period (10 -
15 sec).
<On/Off>
Value space:
On: The default value is On.
Off: Some manufactures do not support this feature. By setting Rebonding to Off this functionality
will be disabled.
xConfiguration H320 Bonding Rebonding: On
Example:
xConfiguration H320 DefaultCall Restrict
A restricted call uses 56 kbps channels rather than the default unrestricted 64 kbps channels.
Some older networks (primarily in the USA) do not support 64 kbps channels and require the use
of restricted 56 kbps calls. By default, the system will dial an unrestricted call and downspeed to 56
kbps if necessary.
Value space:
<On/Off>
On: Set to On to force restricted (56 kbps) calls.
Off: Set to Off to disable restricted calls.
Example:
xConfiguration H320 DefaultCall Restrict: Off

network may still send your numbers to the far end.
Example:
xConfiguration ISDN SendNumber: On
Select if the channels in bonding calls should be connected in parallel or one by one.
<On/Off>
Value space:
On: When set to On, channels will be dialled and connected in parallel when setting up a bonding
call.
Off: When set to Off, channels will be dialled one by one, which may increase the dialling time.
xConfiguration ISDN ParallelDial: On
Example:
Select if HCL (Higher Level Capability) information should be included in the setup message (video
