Seizure Sequence for Outgoing Calls
The system will first try and seize the network interface that was entered last (right
at the end of the list). If for whatever reason this interface is not available, it will
then attempt to seize the second last interface, then the third last, etc. (see also
Fig. 2.32).
This is repeated for each outgoing call using the same principle.
This means the call charges tend to accumulate on the network interface entered
last.
S Interface as the Network Interface
An S interface set as "external" is also classified as a network interface and can
be assigned to a trunk group.
Note:
If an S interface is reconfigured within a trunk group (to ETSI or V2), it is
no longer a network interface and is removed from the trunk group.
B Channel Groups
The two user-information channels of a basic access and the 30 user information
channels of a primary rate access can be divided into 2 and 4 B channel groups
("B channel list" setting
not all the B channels of the primary rate access are available. B channel groups
can be separately allocated to a trunk group, for example the primary rate access
on network interface 3.17 can be entered as follows:
• "3.17": All four B-channel groups are allocated to the trunk group.
• "3.17/2": Only B-channel group 2 is allocated to the trunk group.
Initialization value: All B channels are in B-channel group 1.

Dividing up B channel groups is not supported by all network providers.
