Chapter 2 - Digital Station Features
Battery Back-Up (Memory)
A lithium battery is located on the Master Processor Board (MPB) of the
protect system memory in case of commercial power outage or the system power being
turned off for a time period.
Battery Back-up Memory retains all system features including system and station speed dial
during a power outage.
Busy Lamp Field
When a button on an Digital Telephone is assigned as a DSS, it also serves as a Busy Lamp
Field (BLF) to display the status of that telephone.
Call Back
A station can initiate a call back request to another busy station. Once that station becomes
idle, the station that left the call back request is signaled.
Call Cost Display
The Call Cost Display feature allows a user to view the approximate cost of each call made.
This approximate cost is also printed as part of the SMDR record. The Call Cost Display
replaces the call duration display when a call is made using LCR. This display is enabled in
programming.
The cost information is programmable by selecting one of the 16 route list tables and one of
the four time periods. This allows the user to program four separate costs based on the time
of day for each of the 16 routes. The costs entered in the tables is a cost for one minute,
however, costs are calculated using a 1/10th of a minute value. These costs are rounded
down and are based on the start time of the call, even if the call extends into a different time
period. The SMDR printout contains a cost calculated using a 1/10th of a minute increment
and the display updates approximately every 30 seconds. The user must have LCR enabled to
get the call cost display.
Call Coverage
The Call Coverage feature provides the functionality for stations to answer calls for other
stations by utilizing call coverage buttons. Visual and Audible status of ringing stations to an
assigned coverage station are provided. Multiple coverage stations can have the same
remote ringing station(s) programmed on their stations. Once a coverage station answers the
call, other stations attempting to answer the call receives busy tone and the call coverage
button extinguishes on all appearances of that button.
