Explanation:
PBX-1 makes a call.
Extension 1001 of PBX-1 dials the TIE Line Access number "7", the PBX code "903", and an extension
number "1001".
1.
The TIE Line Access number was dialed, therefore PBX-1 checks its TIE Line Routing and
Modification Table. Finds leading number "903". 1st priority CO line group is "2".
2.
No lines are available in this CO line group. The PBX checks for an available line in the 2nd priority
CO line group (CO line group 1), and finds an available line. No modification is programmed.
3.
PBX-1 removes the TIE Line Access number and sends the remaining digits down the TIE line via
CO line group 1. The number is now "903-1001".
PBX-2 receives the call.
1.
PBX-2 checks its Incoming Number Modification Table (not shown here). No modification is
programmed. The number is still "903-1001".
2.
PBX-2 checks its TIE Line Routing and Modification Table (not shown here). Finds leading number
"903". 1st priority CO line group is "8". No modification is programmed.
