7.2
The page voice pair is 600 ohm impedance. When the amplifier page input is not 600
ohm, use an impedance matching transformer. The paging contact pairs are for control
of low voltage circuits or amplifier output. The contacts are rated at 24 VDC–1 amp.
WARNING
: Do not attempt to connect commercial AC power to these contacts.
7.3 COMMON BELL
A customer-provided loud ringing device can be controlled using a dry contact pair on
a MISC daughter board.
. By using MMC 204, programming allows for
interrupted or continuous operation of the contacts. The interrupted selection follows
the C.O. ring cadence—one second ON/three seconds OFF.
After connecting a common bell, you must assign it in MMC 601 to a group as a ring
destination by using the code for common bell. The basic steps for common bell
operation are the following:
a. Wire the loud ringing device to the common bell control contact pair.
b. Set contacts for continuous or steady operation.
c. Program the hunt group to include the common bell.
d. Assign the trunk to ring the hunt group containing the common bell.
Common bell control can be used with station hunt groups, individual stations and
Universal Answer. Contacts are rated at 24 VDC–1 amp.
WARNING
: Do not attempt to connect commercial AC power to these contacts.
7.4 RING OVER PAGE
When a customer-provided paging system is installed, incoming calls can be assigned
to ring over page. Program the C.O. line or C.O. lines to ring a hunt group. Using MMC
601 assign the DN number of the Page Output (voice) for the MISC board being used
as a member of the group or as the NEXT PORT for the overflow destination. Other
stations may be assigned to the same group to provide ringing to phones and the
paging system at the same time.
