Description of Assigning Items
Up to 36 routing patterns can be programmed in this table.
This table is referenced by the system to identify the trunk route, when an extension user made a tie call
by dialing the feature number for "TIE Trunk Access" or "Other PBX Extension number".
A routing pattern appropriate for each call is decided by the first three digits (except tie trunk access code)
of the dialed number.
