Major Alarm Alerting
Major alarm rings occur whenever a number of faults exceed a.
programmed threshold. Starting with software release
7.A,
you can
use a telephone station to clear a major alarm ring by pressing the
INTERCOM button and then dialing a feature code (default code is
#09).
However, the telephone station must have a class of service
(COS) assigned to it that has this feature enabled.
Central Message Desk
Use this procedure to designate one station as the central message
desk: to take messages for other system stations, control the message
waiting light at those stations, and deliver messages to their users upon
request.
NOTE:
Do not assign this feature to voice mail station ports since
it activates only one port and inhibits all other station
ports from having message wait originate capability.
ET
Ringing Per Phase
You can connect two industry-standard telephones per IST station
port; however, those ports will share the same assigned intercom
number. When you install one telephone per port, you must set the
IST ringing per phase feature to 16. When you place two telephones at
any IST station port, you must change the IST ringing per phase
feature to 8. A setting of 16 allows up to 48 industry-standard
telephones per cabinet (main cabinet and expansion cabinet) to ring
simultaneously. A setting of 8 reduces this simultaneous ringing total
to 24 telephones per cabinet. This programming selection is on a
system-wide basis.
IST Ringing Patterns (Ring
Mode)
You can program the ringing pattern for either IST ring mode-l or
ET
ring mode-2. Mode-l causes a two-second ring phase while mode-2
causes a shorter one second ring phase. For this feature to function
properly, ensure that the DXIST (industry-standard telephone interface
board) contains firmware revision 2C or higher
IST Ring Frequency
The system will allow you to set a ring frequency of 25 Hz for
international applications or set a ring frequency of 21 Hz for
domestic applications. Choose a setting that matches the ring
frequency of the installed ring generator.
