General Description
This feature provides a visual indication at the Attendant Console of incoming and outgoing trunk calls through the
CCIS network. Trunk Identification number, Trunk Route number, and tenant number or Central Office trunk code,
are displayed on a six-digit digital display.
Operating Procedure
The digital display is automatically activated whenever the Attendant answers or originates a trunk call.
Service Conditions
1.
All trunks (WATS, FX, CCSA and TIE) will appear on the digital display.
2.
The tenant number is displayed on the left side of the digital display, followed by the Trunk Route number,
and then the Trunk Identification number.
3.
If the Trunk Route number is three digits, the tenant number is not displayed.
4.
The DIGITAL DISPLAY is limited to six digits. Because the Class Of Service and Trunk Route displays
are in numerical form, a list must be provided for the Attendant, giving an explanation of each Class Of
Service and Trunk Identification number.
5.
The DIGITAL DISPLAY-TRUNK - CCIS feature displays either Trunk Route information or a four-digit
Central Office code. These options are selected on a per-trunk-group basis.
6.
When Trunk Route information is displayed, one digit identifies the tenant, two digits identify the trunk
group, and three digits identify the trunk number.
7.
The DIGITAL DISPLAY-TRUNK - CCIS will appear automatically whenever the Attendant answers or
originates:
a.) An incoming C.O. call
b.) Incoming TIE Line call
c.) Intercept call
d.) Outgoing C.O. call
e.) Outgoing TIE Line call
f.) Reenters a held trunk call.
