TIE-to-CO Line Calls
An extension user can make a CO line call by first routing the call through another PBX. These
calls can be routed by Automatic Route Selection (ARS), or restricted based on the Class of
Service (COS) of the CO line group carrying the call.
a)
TIE-to-CO Line Calls[Example]
[Example]
Explanation:
PBX-1 makes a call.
Extension 1001 dials the TIE Line Access number "7", the PBX code of PBX-2 "902", and the
Idle Line Access number of PBX-2 "9", followed by the telephone number "1-212-555-1234".
1.
The TIE Line Access number was dialed, therefore PBX-1 checks its TIE Line Routing
and Modification Table (not shown here). Finds leading number "902". No modification is
programmed.
2.
PBX-1 removes the TIE Line Access number and sends the remaining digits down the
TIE line. The number is now "902-9-12125551234".
PBX-2 receives the call.
1.
PBX-2 checks its Incoming Number Modification Table (not shown here). No modification
is programmed. PBX-2 removes its PBX code "902". The number is now "9-
12125551234".
2.
PBX-2 recognizes its Idle Line Access number, "9", and sends the remaining number,
"12125551234", to the telephone company using an idle CO line.
b)
TIE-to-CO Line Calls Routed by ARS
ARS can be used to route calls through other PBXs. This allows PBX users to dial telephone
numbers as they normally would (i.e., by dialing the Idle Line Access number "9" then the
telephone number) without having to think about which calls will be routed through another
PBX via TIE line, and which calls will be sent to a CO line connecting their PBX to the
telephone company.
