MESSAGE REGISTRATION
Page 180
Description
This feature allows the system to accumulate the number of com-
pleted local call units made from an extension. The number of call
units counted for each call is dependent on the call unit modifiers
selected. The accumulated call unit counts are held in the system
Message Registers. These registers are protected against power fail-
ure, so that call counts are not lost in the event' of a power failure.
When the Message Register overflows, a minor alarm will be raised at
the console.
Conditions
The DESTINATION display can show a value of up to 9999. After
l
this, decimal points are lit in sequence starting from the right of
the display, to indicate an increment of 10,000; e.g., a display of
43. 2.8. is actually 4328 + 10,000 + 10,000 + 10,000 or 34328. The
maximum count that may be displayed is 49999:
The maximum count which may be printed is 65535.
l
Programming
The COS of the extension for which a call unit count is to be
l
accumulated must contain COS Option Number 64 (Message
Register).
Select System Option 192 (Message Registration Enable).
If all supervision signals except pseudo answer supervision are
l
to be counted, select System Option 193 (Message Registration:
Count Additional Supervisions). If this option is not selected, only
the first supervision received is counted.
If the CO trunk does not supply answer supervision, pseudo
answer supervision will be generated after 20 seconds if System
Option 194 is selected, or after 40 seconds if System Option 195
(Message Registration: Timer = 40 seconds) is selected. If neither
of these options are selected, pseudo answer supervision is
generated after 30 seconds. If both options are selected, pseudo
answer supervision is generated after 60 seconds.
If any one of System Options 199 through 206 are programmed,
the selected surcharge is added to the first answer supervision
signal received. If none of these options are selected, no sur-
charge is made.
If any one of System Options 196 through 198 are selected, the
l
contents of the message register is multiplied by the selected
multiplier (2, 3, or 4) when the content of the message register is
displayed.
Select System Option 113 (GUEST ROOM Button Enable).
The first digit of the TYPE code for the trunk groups used, must
be programmed as Type 1 if answer supervision is not generated
by the CO (No Supervision), or Type 4 (Outgoing Audio +nhibit
Until Answer Supervision) may be used if answer supervision is &
provided. The second digit of the trunk group type must be Q\
specified as either 2 (Message Register) or 4 (SMDR pius Mes-
