1.1.1.1 Incoming CO Line Call Features—OVERVIEW
Description
CO lines are used to connect a PBX to a public network, i.e., the telephone company.
1.Distribution Method
Each CO line port uses a method of distributing calls to their destinations as they are 
received.
2.Available Destination
The following destination types can be programmed as DIL or CLI destinations.Distribution

1.1.1.2 Direct In Line (DIL)
Description
Directs an incoming CO line call to a preprogrammed destination based on the CO line carrying 
the call. Each CO line has a destination for each time mode.
[Method Flowchart]
[Programming Example: DIL Table]
The table can be programmed for each CO line.
In this example:
If a CO line call is received on CO line 01:

destination, if assigned. If not assigned, the call is routed to the Direct In Line (DIL) destination, 
extension 101.
In lunch mode: CLI distribution is disabled. The call is routed to the DIL destination, extension 
100.
Note
Tenant numbers and VPS trunk (CO line) group numbers (not shown here) can also be 
programmed in the DIL Table.
The tenant number programmed here is used only to determine the Time Table used by 
each CO line; selecting tenant 3 means the CO line will use Time Table 3, for example. 
The VPS trunk (CO line) group number set here is used to determine the Incoming Call 
Service and greeting message used by the Voice Processing System (VPS) during the 
current time mode. (  1.19.2 Voice Mail DPT (Digital) Integration).

1.1.1.3 Calling Line Identification (CLI) Distribution
2.2.4 Time Service
1.1.1.3 Calling Line Identification (CLI) Distribution
Description
Directs an incoming CO line call to a specific destination when the caller’s telephone number 
matches a number in the System Speed Dialing Table. Each telephone number in this table 
can be assigned its own Calling Line Identification (CLI) destination.
CLI distribution allows you to direct calls from specific people to specific destinations, and has 
many applications. For example, you can program the PBX to automatically connect calls from 
priority clients to their sales representatives, or automatically connect mobile phone calls from 
an executive to his or her assistant.
In order for CLI distribution to function, the PBX must receive Caller ID information from the 
telephone company.
CLI distribution works in conjunction with Direct In Line (DIL) distribution; it can be enabled or 
disabled for each time mode assigned on each CO line.
When a call has Caller ID information and CLI distribution is enabled for the current time mode, 
CLI distribution will direct the call to its destination, ignoring preprogrammed DIL destinations.

In this example:
If the caller’s telephone number is 1-212-555-1234:
1)The PBX looks for the number in the System Speed Dialing Table. (The CO Line 
Access number, 9, is disregarded.) The number is found in location 000.
2)If CLI distribution is enabled in the current time mode for the CO line carrying the call 
(for DIL distribution), the call is routed to its CLI destination, extension 200.
Conditions
If Automatic Caller ID Modification is used:
Store the modified number in the System Speed Dialing Table.

1.1.1.4 Intercept Routing
Description
Redirects an incoming CO line call to a preprogrammed destination when the original 
destination does not, or can not, answer the call. There are four types of Intercept Routing, 
described below.
Intercept Routing redirects calls to destinations based on the original destination of the call, as 
shown in the table below. Different intercept destinations can be programmed for each time 
mode. Note that calls redirected by Intercept Routing—No Answer/Busy/DND are directed to 
the same destination, and that the intercept destination for Intercept Routing—No Destination 
is always an operator.Type Description
No Answer (IRNA)If a called party does not answer a call within a preprogrammed 
time period (  Intercept Time [203]), the call is redirected to a 
preprogrammed intercept destination.
BusyIf a called party is already handling a call, new calls are 
redirected to a preprogrammed intercept destination.
DNDIf a called party is in Do Not Disturb (DND) mode, the call is 
redirected to a preprogrammed intercept destination.
No DestinationIf a call has no destination (i.e., if a destination is not assigned), 
the call is redirected to an operator. (  1.1.1.5 Intercept 
Routing—No Destination)
When the original destination is: The Available Intercept Destination is:

[Available Intercept Destination]
The following can be used as intercept destinations:
Conditions
If the intercept destination is busy or in DND mode and therefore cannot receive the 
call:
a)When the call was intercepted via Intercept Routing—No Answer, the call is sent back 
to the original destination and continues to ring at the original destination until 
answered. ICD Group The ICD Group Overflow destination assigned to

* Intercept Routing will redirect a call only if the Direct Inward System Access (DISA) line is 
busy. Once a call reaches the destination extension using the DISA feature, the call can 
be redirected to the Intercept Routing destination assigned to that extension.

b)When the call was intercepted via Intercept Routing—Busy, the call waits at the 
original destination. If the extension has Call Waiting activated, the user will hear a 
call waiting tone.
c)When the call was intercepted via Intercept Routing—DND, the call waits at the 
original destination and it rings.
If the intercept destination can, but does not, answer the call:
The call continues to ring at the intercept destination until answered.
Intercept Routing—Busy/DND on/off
Intercept Routing—Busy and Intercept Routing—DND can each be enabled or disabled 
for the entire system, through system programming. If enabled, calls will be routed to the 
appropriate destination.
If disabled, the caller will hear a ringback tone. If busy, the extension will not ring. If in DND 
mode, the extension will ring.
Idle Extension Hunting
If an extension is a member of an idle extension hunting group, calls to that extension will 
not be redirected by Intercept Routing—Busy/DND. If the extension is busy or in DND 
mode, calls to that extension will be redirected to the next extension in the idle extension 
hunting group.

1.1.1.5 Intercept Routing—No Destination
Description
Directs a CO line call to an operator when the call has no assigned destination.
Conditions
If an operator is not assigned: 
The default intercept destination will be the extension connected to the lowest numbered 
port, on the card installed in the lowest numbered slot.
Intercept Routing—No Destination also applies to calls from doorphones.

1.1.2.2 Internal Call Block
Description
Internal calls can be restricted based on the Class of Service (COS) assigned to the caller and 
to the called party.
[Programming Example: Internal Call Block]
In this example:
a)COS 1 can make calls to all extensions.
b)COS 2 can make calls to COS 1 only. (COS 2 cannot make calls to COS 2.)
c)COS 3 can make calls to COS 3 only.
Conditions
Internal Call Block also prohibits certain features, such as Walking Extension and Walking 
COS, from being performed between certain extensions.
Any extension can make an Operator Call regardless of the Internal Call Block setting of 
its COS. (  2.2.5 Operator Features)
Because each doorphone port is assigned a COS, the Internal Call Block feature can 
restrict certain extensions from calling certain doorphones. (  1.15.1 Doorphone Call)
