Special Dial Tone
Provides the ability to play a Special Dial Tone whenever an analog set is not able to
receive calls. When such conditions as Call Forward All Calls, Call Forward
Busy/NA, Send All Calls or Do Not Disturb are activated on a telephone set, a Special
Dial Tone lets you know that you cannot receive any calls.
Call Charge Information
DEFINITY ECS provides two ways to know the approximate charge for outgoing
calls:
• Advice of Charge — For ISDN trunks
Advice of Charge collects charge information from the public network for each
outgoing call. Charge advice is a number representing the cost of a call; it is
recorded as either a charging or currency unit.
• Periodic Pulse Metering — For non-ISDN trunks
Periodic Pulse Metering accumulates pulses transmitted from the public network
at periodic intervals during an outgoing call. At the end of the call, the number of
pulses collected is the basis for determining charges.
Call-charge information helps you to account for the cost of outgoing calls without
waiting for the next bill from your network provider. This is especially important in
countries where telephone bills are not itemized. You can also use this information to
let employees know the cost of their phone calls, encouraging them to save money on
toll calls.
Telephone Displays
• Telephone Display — Provides multi-appearance telephone users with updated
call and message information. This information is displayed on a display-
equipped telephone. The information displayed depends upon the display mode
selected by the user. Information that allows personalized call answering is
available on many calls.
Users may select any of the following as the display message language: English
(default), French, Italian, or Spanish. In addition, messages can be administered
on the system in a fifth language. The language for display messages is selected
by each user.
• ICLID on Analog Trunk — In the US, the user’s telephone displays calling party
information. Name and calling number are available from the US central offices.
This feature may be used in countries that comply with either US. The display of
name and number will work with all DEFINITY digital telephones (DCP and
BRI) equipped with a 40-character or a 32-character alphanumeric display.
• Enhanced Telephone Display — The Enhanced Telephone Display feature allows
you to choose the character set that you want to see in DEFINITY ECS softkeys
and display telephones. In addition to the standard Roman character set, you can
choose either the Katakana or characters used for most European languages.
