iDCS 100 INSTALLATION
TECHNICAL MANUAL PART 7 JUNE 2002
7.2
The SMISC card also provides a second independently controlled page output voice
pair to be used with customer-provided paging equipment. Connect the customer
provided paging equipment to the page 2 output pins of the P1 connecting block (see
Figure 7–3). The page voice pair is 600 Ohms impedance. When the amplifier page
input is not 600 ohm, a suitable impedance matching transformer must be used.
7.3 COMMON BELL
A customer-provided loud ringing device can be controlled using one of the relay
contact pairs on the SMISC card (see Figure 7–5). Each of these 3 relays can be
individually defined as a common bell in MMC 219 and assigned in MMC 204. These
relay contact pairs are for control of low voltage circuits or amplifier output. The
contacts are rated at 24 VDC-1 amp.
Programming allows for INTERRUPTED or CONTINUOUS operation of the contacts
using MMC 204. The interrupted selection follows the C.O. ring cadence—one second
ON/three seconds OFF.
After connecting a common bell, you must assign it to a group in MMC 601 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. Program the relay as a common bell in MMC 219.
c. Program the contacts for continuous or steady operation.
d. Program the station hunt group to include the common bell.
e. 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 line or lines to ring a hunt group. Using MMC 601,
assign ROP as a destination in this hunt group. Ring over page can be used for day or
night operation or both.
7.5 STATION MESSAGE DETAIL RECORDING (SMDR)
To receive an SMDR printout, connect a customer-provided printer to one of the serial
interface connectors on the SMISC card (see Figure 7–6). SI/O 2 defaults as SMDR.
