 ID

from the top line appears on the bottom line. After an additional five 
seconds, if the Caller ID information from the top line exceeds the 
capacity of both display lines, the numeric portion is removed and only 
the name portion appears in the display.

The Caller ID information that appears in the telephone display panel can 
be different in some specific call situations.

Analog telephones can be connected to the NBX system using these 
interfaces:

■

NBX single port Analog Terminal Adapter

■

A port on an NBX Analog Terminal Card

■

Citel Analog Interface Card

If you have an analog telephone connected to the NBX system using a 
single port Analog Terminal Adapter or to a port on an Analog Terminal 
Card, the behavior of Caller ID on the analog telephone (or on Caller ID 
boxes connected in-line with the analog telephone) depends on whether 
the Caller ID device/telephone supports 2-line Caller ID display.

■

Most analog telephones with built-in Caller ID and most Caller ID 
boxes do not support 2-line display of Caller ID information. For this 
type of device, only the Caller ID of the original caller appears.

■

If the analog telephone or Caller ID box supports 2-line display of 
Caller ID information, the information appears in the same way as it 
does on an NBX telephone. 

If the Caller ID information exceeds the capacity of the Caller ID display 
(some can display 16 characters and others can display 24 characters) the 
Caller ID information is typically truncated at the width of the display.

If you have analog telephones connected to the NBX system using the 
Citel analog interface card, the behavior of Caller ID on the analog 
telephones is the same as the behavior of analog telephones connected 
to a single port Analog Terminal Adapter or a port on an Analog Terminal 
Card. See
