Common Bell; Ring Over Page; Loud Ringer; Smdr - Samsung DCS Installation Manual

Samsung DCS Part 7
Installation March 2001

7.3 Common Bell

A customer-provided loud ringing device can be controlled using the dry contact pair on
the MISC card (Figure 7–3). Using MMC 204, programming allows for interrupted or con-
tinuous operation of the contacts. The interrupted selection follows the C.O. ring cadence.
After connecting a common bell, you must assign it to a group as a ring destination by us-
ing the code for common bell (see MMC 601).
The basic steps for common bell operation are the following:
1. Wire the loud ringing device to the common bell control contact pair.
2. Program the contacts for continuous or steady operation.
3. Program the station group to include the common bell.
4. Assign the trunk to ring the station group containing the common bell.
Common bell control can be used with station groups, individual stations and Universal
Answer. Contacts are rated at 24 VDC–1 amp.
NOTE: The system does not supply ringing voltage.
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 Ring
Page as a destination in this hunt group. Ring Page can be used for day or night operation
or both.

7.5 Loud Ringer

The MISC card is equipped with a ring output*. Connect this pair to a customer-provided
amplifying device (Figure 7–1). Assign the output to a station in MMC 205. After the loud
ring output has been assigned, the loud ringer will ring when the station rings.
* NOTE: This is a tone only supply. It should be connected to an external bell kit.

7.6 SMDR

To receive an SMDR printout, connect a customer-provided printer to the serial interface
(RS232) connector on the back of a SIM (Figure 7–4).
Use a pin-to-pin RS232C cable. Only pins, 2, 3, 7 and 20 are required (refer to Figure 7–7).
When the printer or optional call accounting device needs to be more than 15 feet away
from the KSU, use shielded computer cable. Attach a male DB25 connector to the SIM end
and a connector that matches the requirements of the call accounting device or printer to
the other end. This cable must not exceed 300 feet.
