B Channel Allocation 
 
Implementing features, see also Manager E B Channel Allocation

Definition  
This feature allows you to allocate outgoing connection B channels on an S2M link to different trunk groups.
For outgoing calls, only B channels that also correspond to the trunk group are selected (by the code-selected trunk group, overflow trunk group, or LCR-selected trunk group). If there is no free B channel available for this trunk group, the system rejects the connection request and reacts in the way it has been configured.
Incoming calls are always accepted if a B channel in the corresponding S2M line is available, regardless of the trunk group. This is usually the B channel offered by the partner. If the remote system or the public network does not support B channel allocation, there is no guarantee that the call will be correctly assigned to the right trunk group.
HiPath 3000/5000 Manager E allocates an S2M link to the trunk groups; a route can be assigned to each line (B channel).

IP networking  
B channel allocation is not useful in IP networking because it is not possible at this time to assign incoming calls to the correct trunk group.
