Note:
When supporting DCS, Member Number Assignments must be the same
Note:
between nodes (Member #1 must be Member #1 at the far-end trunk group).
Port
When using ISDN-BRI interfaces, B-channel 1 is the port number while B channel 2 is the port
number plus 16. For example, if B channel 1's port number is 01A1002, then B channel 2's port
number is 01A1018.
When using ISDN-PRI interfaces, the port number will be the one allied with the B-channel. For
example, if the DS1 is located in 01A10, then B channel 1 will be 01A1001, B channel 2 will be
01A1002 and so forth.
Sig Grp
This field appears when the Group Type field is isdn-pri. Enter the signaling group of this trunk
group member. Valid entries are from 1 to 650, and must be configured for IP group members. If
you administer a port that resides on a DS1 board and that DS1 board belongs to one and only
one signaling group, you can leave the Signaling Group column blank. Then, when you submit
the screen, the appropriate default signaling group number is inserted by Communication
Manager. If a DS1 board is assigned to more than one signaling group, then you must enter a
signaling group number. You must enter a signaling group if the port is entered as IP. A trunk
group can contain members from different signaling groups.
