1.25 Networking Features
200 Feature Guide
[Example]
Explanation:
A call is received on CO line 01 of PBX-1.
1. The call is directed to extension 1001, which is assigned (not shown here) as the DIL
destination for CO line 01 in the DIL Table of PBX-1. (→ 1.1.1.2 Direct In Line (DIL))
2. Calls directed to extension 1001 are redirected to extension 2001 because of one of the
following:
a) Extension 2001 is programmed (not shown here) as the FWD or Intercept Routing
destination for calls to extension 1001. The destination is programmed as "2001".
b) The extension 1001 user transferred the call to extension 2001 by pressing the
Transfer button and dialing "2001".
3.2. 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.
