Screen Reference
Sig Grp
Thsi 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 may contain members from different signaling groups.
