Class Of Service
Block Programming
A programmer can assign a particular line or station’s
class of service to an entire block of lines or stations
with one programming action. This feature eliminates
the need for him or her to individually program stations
and lines with the same class of service. A
programmer can perform a block programming class
of service after he or she has programmed a station
class of service or line class of service for a particular
station or line.
Class Of Service Programming (From Main Station)
Class of service (COS) programming is used by the
installer/programmer to configure and assign all
system, line, station, and special purpose operating
features. The installer/programmer enters COS
programming by dialing an access code over the
intercom line. System administrators can enter COS
programming with another code to reprogram any
system, station, or special purpose operating feature
that may require change at a later date. Line
reprogramming ability is not available through system
administration programming. The system attendant
can reprogram certain system-wide features that
require periodic change by entering COS
programming with another code provided for this
purpose. The station user can program individual
stations for speed dial, autodial and direct station
selection (DSS) by entering COS with a code provided
for that purpose. Thus, COS programming is arranged
with a hierarchical order from the highest(the
installer/programmer) to the lowest (the station user)
level with a higher level programmer having the ability
to do anything a lower level programmer can do
without exiting a current programming mode.
However, only the station user can program the speed
dial and autodial locations at a telephone.
All class of service (COS) programming is performed
from station 10 or 12. Any station and console
combination will function in this mode and provide
visual feedback with the LED associated with the
programming button. By employing an LCD
speakerphone, however, the programmer will have the
benefit of display prompts and verifications to simplify
and clarify the programming procedures. Class of
service programming access is as follows:
Flexible Station And Line Class Of Service Control
The extension number of a station and all other
programmable attributes that are initially assigned to a
particular station port and the line, along with all
programmable line attributes that are initially
connected to a particular line port can be re-assigned
to a different port through programming action. This
feature allows adds, moves, and changes without

Description Of System Features
re-locating the station and line wiring. A programmer
can use line and station class of service programming
are used to reassign stations and lines.
Class Of Service Programming (Video Display Terminal)
A programmer can use an asynchronous, serial data
terminal with an W-232 interface to effect class of
service programming through menu-driven
procedures. VDT programming provides a
menu-driven approach to programming that is
discussed in Chapter 4.
Class Of Service Program Printout
The common equipment provides serial data ports that
the installer can use to interface an RS-232
compatible, asynchronous serial data printer to the
system. The connected.printer will provide a printout
of class of service and toll restriction records. The
programmer can use the data printer service class of
service programming procedure to specify the nature
and extent of each requested printout. He or she can
use the system class of service programming to
specify the bit-length and baud rate of the data.
Default Functional Program
At initial power-up, the system sets the operating
features to a specific group of operating conditions
(default conditions). The default conditions provide a
complete operating system for normal use. The
installer can leave the system defaulted or reprogram
as desired. After a programmer has reprogrammed a
system, he or she can re-default it by using the
system, line, and station class of service programming
or use a master clear to default the entire system and
erase all stored programmable button information.
,
Remote Programming And Administration
Both remote class of service programming and the
transmission of SMDR data for printing are available
through serial data ports. The system supports X-on
X-off terminal control codes as well as a DTR signal
for handshaking. The system data communications
operates per the popular XMODEM protocol. The
database can be uploaded or downloaded, error free,
from or to a remote computer that is running software
that supports the XMODEM protocol. The two serial
data ports allow VDT programming (either local or
remote) to be conducted through one port at the same
time that the other port is being used to send SMDR
data for printing. VDT programming of the system is
menu driven.
