2. PBX-2 checks its Extension Numbering Plan. "2001" is one of its extensions.
3. PBX-2 sends the call to extension 2001.
4. Calls directed to extension 2001 are redirected to the outside party (1-212-555-1234)
because of one of the following:
a) This number is programmed (not shown here) as the FWD or Intercept Routing
destination for calls to extension 2001. The destination is programmed as "9-
12125551234".
b) The extension 2001 user transferred the call to the outside party by dialing "9-
12125551234".
3.3. CO-to-TIE-to-CO Line Calls
An incoming CO line call can be routed to the DISA feature of a PBX, then the caller can make a
CO line call which is routed via ARS through another PBX.
[Example]
Explanation:
The outside caller dials a telephone number which is routed to the DISA feature of PBX-1, then
dials the Idle Line Access number of PBX-1 "9", followed by the desired outside party's telephone
number "1-212-555-1234"
1. The Idle Line Access number "9" was dialed, therefore PBX-1 modifies the dialed number via
its ARS programming (not shown here). It removes the first digit "9", adds the Idle Line Access
number of PBX-2 "9", and sends the number down the TIE line to PBX-2. The number is now
"9-12125551234".
2. PBX-2 checks its Incoming Number Modification Table (not shown here). No modification is
programmed.
3. PBX-2 recognizes its Idle Line Access number, "9", and sends the remaining number,
"12125551234", to the telephone company using an idle CO line.
Conditions
• PBX Code
If a PBX is assigned a PBX code, it will not handle calls received via TIE line with the Extension Number
Method (Access without PBX Code). Only assign a PBX code when using PBX Code Method (Access
with PBX Code). (→ 1.27.1.2 PBX Code Method (Access with PBX Code))
