4.3.1 TIE Line Service
<PBX Code Method (Access with PBX Code) using ARS>
PBX-1
PBX Code 951
Interface
Extn. 1011
Dials "9-211-4567".
Explanation:
1.
Extension 1011 of PBX-1 dials the Idle Line Access number of PBX-1 "9" and telephone number
"211-4567".
2.
PBX-1 modifies the call (adds "952" and the Idle Line Access number of PBX-2 "9") and sends the call
to PBX-2 which has PBX code "952" through the TIE line (trunk group [TRG] 2) according to the ARS
programming of PBX-1.
3.
PBX-2 sends the call to the outside party "211-4567".
b.
Blocking trunk calls made through another PBX and how to override it:
Whether an incoming TIE line call can make a trunk call through this PBX (i.e., PBX-2), depends on the
COS that is assigned to the trunk group of this PBX, that the incoming TIE line is connected to. If the COS
of the trunk group is unable to make outgoing calls by the Toll Restriction/Barring feature or External Call
Block feature, trunk calls made through this PBX will be prohibited.
To override this prohibition, an extension of PBX-1 must enter a verification code assigned to PBX-2 to
change the COS temporarily. It is also possible to override the prohibition by specifying an extension at
PBX-2 with the Walking COS feature, to temporarily switch to that extension's COS.
