Specifications
• Reset switch is used to manually reset the system during troubleshooting. This is a soft-
ware-controlled system reconfiguration. Pushing this switch does the following:
— Preserves the battery-backed database information, all calls in progress, outside
calls being placed, pages in progress, camped-on calls, queue requests, system and
user programming, inter-station messages, calls on system and individual hold,
do-not-disturb messages, and reminder messages.
— Restores DTMF receivers, modem access, and speech channels, and resets the sta-
tion clocks to match the system clock. Updates trunk button, DSS/BLF button,
speed-dial button, and feature button lamp status.
— Disconnects calls ringing in.
NOTE: If necessary, the reset switch can also be used to place the CPU Card into
“receive software upload” mode, as described in INSTALLATION.
• Database back-up battery (3.6V, ½AA lithium battery) that can support the database
for at least two months of accumulated system down time.
• Battery voltage test points and check button for checking the database back-up bat-
tery charge. If the battery voltage is not greater than 3.3VDC, replace the battery.
• Battery back-up jumper strap for activating the database back-up battery. The jumper
strap should be placed in the ON position (over the back two pins) before the CPU Card
is installed. When the card is taken out of service for repair or storage, the jumper strap
should be placed in the OFF position (front two pins) to preserve the battery charge.
NOTE: Placing the BATTERY jumper strap in the OFF position erases the database
when the card is unplugged or loses power.
• Music jack for connecting an external music source (such as a radio, CD player, tape
player, etc.) that can be heard by callers when they are placed on hold or camped on. It
may also be used for phone background music. This is a 1/8-inch (3-mm), two-conduc-
tor (mono), mini-phone jack. In DB Programming, music can be enabled or disabled,
and each trunk group (as well as transfer audio) can be assigned music, silence, or tick
tones.
• Relay jack (6-pin, 6-conductor modular jack) currently used for power failure transfer
equipment only. A power failure transfer jack can be used for connecting one or more
single-line sets to predetermined CO trunks in the event of processor card failure or a
power failure. The output is one normally-open (deactivated) double-pole double-throw
(DPDT) relay (actually wired as SPDT) that is held closed (activated) during system
operation. Additional equipment needed includes a customer-provided PFT relay card
and card mounting case. The relay contact ratings are listed below.
• Real-time clock for date and time function.
• External paging jack (RCA-type phono jack with an output impedance of 600 ohms)
for connecting external paging speaker equipment to allow paging to large areas, such
as warehouses or loading docks.
