SYSTEM PROGRAMMING

GENERAL INFORMATION
aClass Of Service (COS) programming consists of setting the Class Of
Service (COS) operating-condition&.
COS programming 'Is divided into
the following three major categories: General System COS, Line COS,
and Station COS.

All COS programming commands must originate at station 10.
No COS
programming commands can be accepted from any other station
connected to the system.
COS programming causes station 10 to
default to a square condition (line select key 1 selects line 1, key
2 selects line 2, etc.). It is recommended that station 10 always
remain in a square condition to avoid possible programming
confusion.
COS programming does not require that a sequential process be
followed once the base level program entry mode has been established
except where noted herein.
The system defaults to preset characteristics when it is initially
powered up or whenever programmed to do SO.
If the default
characteristics,
or any other previously set characteristics, are
satisfactory,
those portions of the programming sequence may be
omitted.
Prior to taking any programming action, record the system, line and
station COS conditions on Table 2a,
2b, and 2c (included at the end
of this chapter).
Also,
record all toll restriction requirements on
Table 2d.
THE PROGRAMMING STEPS MUST BE PERFORMED WITH LESS THAN 17
SECONDS OF
DELAY TIME BETWEEN
KEYSTROKE OPERATIONS.
A delay of longer that 17
seconds causes the KSU programming mode to time out.
BASE LEVEL PROGRAM ENTRY MODE
The first step in a COS programming sequence is to enter the base
level programming mode.
Once in this mode,
COS can be set as desired.

Press the

key.
The dial tone will sound.
Press the following keys in sequence:
(*:5)m@)m
Note that the dial tone stops and a tone burst sounds to indicate
that the base level programming mode is entered.
Press the
0
*i
key.
The dial tone will return as a confirmation
that the base level mode is active.
Proceed from this point to program the COS.
