Dynamic Save Button
Unprogrammed buttons at multiline telephones are available for the user to dynamically save dialed numbers.
To save a number, the user presses any unprogrammed button before hanging up after he or she has dialed a
number. To dial the saved number, the user presses the same button and the system automatically dials the
saved number. Saving a number over a previously saved number erases the old one and stores the new one in
place of it.
E
E1 Digital Carrier Transmission Option
(international applications)
The E1 digital carrier transmission option is designed for international applications and allows up to 30
channels of voice and/or data transmissions over a single four-wire cable using multiplexing techniques. For
convenience, a customer service unit (CSU) is built into the E1 option board to terminate the E1 channels,
provide protection from transient voltages, and respond to loop-back requests from the central office.
Installers can assign a system status button to a station and enable the system to report E1 transmission errors
via the T1/E1 status log. Depending on how they program the system, the E1 status log either prints out on an
optional printer or is displayed on an optional video display terminal (VDT). Users can also view the E1 status
log from an LCD speakerphone.
Also, installers can program the system to alert the system attendant whenever a major alarm alerting condition
occurs by activating an external, customer-supplied audible or visual alarm. Installers determine when a major
alarm alerting condition should occur by programming threshold values and corresponding time periods for
each type of alarm caused by a transmission error. Whenever the threshold value is reached within the
programmed time period the system activates the external alarm. The system attendant can turn the alarm off
from any specified station by dialing a feature code.
