You can configure the system to allocate B-channels for dialout from lowest or highest numbered B-channel (ascending or descending order). By configuring this feature, you reduce chances of “glare” on PRI lines carrying a mix of incoming and outgoing calls.
To configure the B-channel allocation, include the idsn-options and bchannel-allocation statements at the [edit interfaces ct1-pim/0/port | ce1-pim/0/port] hierarchy level.
- [edit interfaces]
- (ct1-pim/0/port | ce1-pim/0/port) {
-
isdn-options {
- (bchannel-allocation (ascending | descending);
- }
