Caller ID
Caller ID
Caller ID allows a display keyset to show an incoming caller's tele-
phone number and/or name with the time and date on the phone's
display. The caller's information can be checked before answering an
incoming call. The information received by the system depends upon
the capabilities of your local telco.
There are two types of Caller ID message formats currently available:
Single Message Format and Multiple Message Format. With Single
Message Format, the telco sends only the caller's phone number (DN).
The DN is either 7 or 10 digits long. In Multiple Message Format, the
telco sends the DN and the caller's name. The DN for this format is
also 7 or 10 digits long, and the name provided consists of up to 15
characters. The data remains stored for the duration of the call.

Caller ID Table
Caller ID information (name and number) can be stored in the sys-
tem's Caller ID Table (up to 100 bins). Keyset users can also make
outgoing calls using the Caller ID Table. The Caller ID Table and the
Temporary Memory bins can only hold a maximum of 10 digits.
Therefore, a long distance number can not be stored in a bin.
