CO Ringing Types
Description
Several types of CO ringing are available for the System including the following:
• Direct Inward Dialing (DID) Ringing
• Direct In Line (DIL) Ringing
• Direct Inward System Access (DISA) Ringing
• Multiple Ringing
These ringing types may be used in any combination in the System.
Direct Inward Dial Ringing
DID Ringing allows calls on a common CO to be directed to ring to a specific extension or group of 
extensions, etc. based upon the final digits dialed. These final digits are received from the DID trunk 
and compared to a DID Table that determines where the calls should ring. Depending on the 49

assignments in the DID Table, names or trunk numbers are displayed. (Names can be up to 10 digits 
long.)
DID Ringing can be very useful by sending calls directly to a specific extension, hunt group, etc. 
based upon the number dialed. Since a relatively small number of trunks handle the DID calls, this 
can be more cost efficient than DIL trunks or attendant group answering and transfer. (DID may send 
a call to a group using the Virtual Extension feature.) DID Busy/Delayed Ringing is also available 
with DID Ringing. (See “DID Day/Night Busy/Delayed Ringing” on page 61.)

• Caller ID takes priority over the DID name assignment.
• Only one of the two DID tables may have name assignments.
Direct In Line Ringing
DIL Ringing allows calls on a specific CO line to be directed to ring a specific extension, System 
Speed Dial (SSD) number (for redirecting calls out), and hunting group.
This can be very useful when a trunk is dedicated to a specific person or purpose. However, this can 
be a more expensive use of the line since it has a more limited use.

Direct Inward System Access Ringing
DISA Ringing (which is related to the DISA feature) allows a CO trunk specified as a DISA CO trunk 
to ring and give off-site users dial-in access to the System. Once the DISA trunk is accessed, the user 
receives dial tone and may dial an extension. 
For more information on DISA, see “Direct Inward System Access” on page 40.

Multiple Ringing
CPC-96, CPC-288, and CPC-576 Version 1.0
Description
Multiple Ringing allows CO calls into the System to be directed to ring multiple extensions in the 
System. This can be very useful when anyone in a group may answer a call. This can also be very 
useful at night when only a selected number of people are available to handle calls.

CO Trunk Interface
Description
The System supports several types of CO Trunk Interfaces including the following:
• Direct Inward Dialing (DID)
• Integrated Services Digital Network (ISDN) - Basic Rate Interface (BRI)
• ISDN - Primary Rate Interface (PRI)
• Loop Start and Ground Start
Each trunk type supports various features such as Delayed Ringing, Night Ringing, etc.
CO Trunk Interface - DID
The DID feature allows an extension to have a dedicated direct number. The dedicated number allows 
calls to be made directly to the extension, without the caller going through the attendant.
The DID number may have from 1 to 4 digits (typically 4).
Each DID Trunk Interface card (VB-44520) supports up to 8 DID trunks.
Hardware Requirements
• The -48V power supply is required.

(DTMF) signaling. 
• DID numbers must be between 0 and 9999.
CO Trunk Interface - Ground Start
Ground start trunks are supported in the System with the VB-44511 Loop Start/Ground Start trunk 
interface. Each card supplies 8 circuits that can be individually configured for either loop start or 
ground start operation.
Ground start trunks are useful in preventing call collision.

Day/Night System Mode
Description
Day/Night System Mode enables you to switch the System between two Day modes and a Night 
mode. These modes determine incoming call handling, Toll Restriction Service (TRS) call handling, 
and attendant group support.
While in a Night mode (generally used at night or any time when your office is closed), incoming 
calls can ring at selected extensions (e.g., a night watchman’s extension or an extension connected to 
an answering machine). Outbound calls can be restricted to certain phones. Calls can be directed to a 
nighttime attendant group instead of the normal daytime attendant group.
The System provides one Night mode for night call handling. However, there are three night feature 
access codes (Night, Night 1, and Night 2). These three codes may be used to provide different two-
way Voice Processing Unit messages (i.e., Night may select one message, Night 1 may select a 
different message, and Night 2 may select a third message.)
Typically, the Day mode is used for normal call processing of outside calls, TRS calls, and attendant 
calls. The second day mode (Day 2) may be used for alternative call handling such as during a lunch 
break, etc. 
There are two ways to change day/night service modes:
• Manually
• Automatically
The following table lists the impact on TRS, Ringing, Attendant, and Built-in Voice Processing Unit 
in the various system modes:

• Day and Night modes can be assigned to FF keys on a phone. You can switch between Day 1, 
Day 2, Night, Night 1, and Night 2 modes simply by pressing the appropriate key. The FF key 
lights red when the System is in the assigned mode. Alternatively a Day/Night toggle mode key 
can be assigned. Pressing the key toggles between modes. When in Day mode, the FF key LED 
is not lit. When in Night mode, the LED lights red.
Automatic Day/Night Mode
You can set the System to automatically enter a particular Day/Night mode determined by the time of 
day. Each day of the month can be assigned 1 of 3 automatic system mode patterns. Each of the 
patterns can be set to change modes up to 5 times per day. 
Up to 20 special days can be programmed with up to 5 automatic mode changes for the day. 
An Exception Day period is available for overriding the automatic mode for extended periods of time. 
For instance, if an office is shut down for the week of July Fourth, the System can be programmed to 
not operate in the automatic mode for those days. The System will stay in the same mode for the 
period. The mode may be manually changed at any time.
For instance, the System can be set to automatically enter Day 1 mode at 8:00 a.m. on weekdays and 
enter Night mode at 5:00 p.m. on weekdays. All incoming calls, TRS and attendant group handling 
would change accordingly. On Saturday and Sunday, the System would stay in Night mode. 
The Automatic Day/Night modes may be set in User Maintenance. See “Set Mode Schedule” on page 
91, “Set Special Day Mode” on page 93, “Set Exception Day Mode” on page 99, and “Set Day of 
Week Mode” on page 101.

Considerations
• You can only set Automatic Day/Night modes on a system-wide basis. If tenant groups require 
separate Day/Night modes, you must set these modes manually.
• You can manually override Automatic Day/Night modes. (See “Manual Day/Night Mode” on 
page 38.)
Digital Pad
Description
Digital pad settings allow adjustment of call levels for different call types. There are 29 pad classes in 
the System. For pad class, a volume adjustment is assigned for a connection to any pad class 
assignment. The volume adjustment is between -30dB and +30 dB.
There are 8 extension pad classes and 16 trunk pad classes. In addition, there are pad classes for 
conference calls, page port, MFR, RAI Modem, and Conference Call Unit. One pad class is currently 
not used.
For instance, a call from an extension assigned to extension pad class 1 to a trunk assigned to trunk 
pad class 3 would received the volume adjustment assigned to this connection combination.

Direct Inward System Access 
(All Versions)
Description
Direct Inward System Access (DISA) gives off-site users dial-in access to the System. You access 
DISA from an outside location by entering a digit number assigned to a DISA trunk.
For security reasons, sixteen incoming DISA ID codes/TRS class can be assigned. If a code is 
assigned, it must be entered as soon as the DISA trunk answers.
