DSI-375 Meridian Custom Ringer

Dees developed the DSI-375, Meridian Custom Ringer, in conjunction
with Northern Telecom. The DSI monitors the DMS-100™ or SL-100™
digital Centrex lines servicing Meridian™ Business Sets (MBS).
The DSI is equipped with a variable frequency electronic ringer and the
ability to close a set of contacts which can be used to control auxiliary
equipment such as aloud ringer or lamp. The DSI will customize the
ringing performance and enhance the functionality of your MBS.

Part 1
Application Overview

The DSI is capable of performing many different functions. These
functions are described as configurations in this User Guide.
Configurations can be linked together so that the DSI can perform more
than one task.
Each configuration is described briefly here. More detailed explanations
are located on pages 18-29.
Configuration 0
Clear Memory or Factory Default Setting
Clears all previous programming and returns DSI to its factory default
setting. See page 18.
Configuration 1
Monitoring Off-Hook Busy
Used to monitor an "off-hook" state. When detected, the DSI will close a
set of contacts which can be used to light a lamp. Configuration 1 can
also be used in conjunction with the "make busy" feature of the Meridian
Business Set so that a set of contacts will close when this feature is
activated. See page 19.
Configuration 2
Second Call or Intercom Alert Tone Amplification
When there is a second incoming call, an intercom call or a ring again
call on the MBS or associated add-on module, the DSI rings once. See
page 20.
Configuration 3
Simultaneous Ringing
When the MBS rings, the DSI rings and activates any connected
auxiliary equipment, e.g., a ringer or a lamp. See page 21.
Configuration 4
Set Idle On-Hook
When an LCD on selected lines flashes, the DSI rings and can activate
any connected auxiliary equipment, e.g., a ringer or a lamp. See page 22.
Configuration 5
Set Busy Off-Hook
When an LCD on selected lines flashes while the MBS is off-hook, the
DSI rings and can activate any connected auxiliary equipment, e.g., a
ringer or a lamp. See page 23.
2
Overview

Configuration 6
Distinctive Ringing
Sets your DSI to ring with a distinctive tone. Choose from ten different
tones or ringing cadences. See page 24.
Configuration 7
MBS Add-On Module
When any LCD on the MBS and its associated add-on module flashes,
the DSI rings and can activate any connected auxiliary equipment, e.g., a
ringer or a lamp. See page 25.
Configuration 8
Controlling Auxiliary Contacts (External Ringers or Lamps)
This is used to control the contacts in the DSI. It enables or disables
contacts to activate auxiliary equipment. See page 26.
Configuration 9
Message Waiting Alert
When the message waiting button is lit, the DSI rings with a distinctive
cadence and/or activates the auxiliary equipment through a set of
contacts. See page 27.
Configuration 10
Hold Reminder
When any selected lines have been left on Hold longer than the
programmed time, the DSI rings with a distinctive cadence. See page 28.
Configuration 11
Hold Detect
When any selected lines are on Hold, the DSI activates the auxiliary
equipment. See page 29.
Note:
Configurations can be linked together to support more than one
application. See page 30.

Part 2
Getting Started

This section contains important information about installing and
programming the DSI.
The following illustration shows the dial pad on the MBS that is used to
operate and set up the DSI. The line buttons that are referenced in the
procedures in this User Guide are also shown. Line button 1 is always
the Primary Directory Number (PDN).
When the DSI leaves the factory, the DSI and the DSI ringer are already
switched on, ready to operate in Day Service mode when power is
applied.
Programming the DSI involves identifying what you require the DSI to do
and then inputting a simple program sequence. To program the DSI
always use the dial pad on the MBS with the handset on-hook. Do not
use the line buttons.
Before you start to program, we suggest that you write down the
configuration string so that input via the dial pad is streamlined.
Always test the input program by calling the DSI's host set from another
telephone.
Applications for which the DSI may be used are described in the next
section and one or more configurations may be linked together. See
Linking Configurations on page 30 for examples and methods.

The programming mode of the DSI is accessed directly after power is
applied to the unit and is identified by the rapidly flashing LED. You have
20 seconds to commence programming before the DSI times out. If you
wait longer than 20 seconds to commence programming, simply unplug
the power supply and reapply power to start again.
Follow the detailed instructions for each configuration. If a mistake is
made in an individual configuration program, beginning of that
configuration sequence. Do not forget to reapply power to the DSI before
recommencing programming.
If you wish to deactivate a single configuration once it has been entered,
follow the configuration instructions as before, but do not press 1 to
activate the feature, instead press 0 to deactivate the feature.
If you are unsure which programs are resident in the DSI, follow the
instructions outlined in Configuration 0, which will erase any programs
and return the DSI to its factory default mode.
When in Day Service mode, the DSI will monitor as many as 10 line
appearances and in Night Service mode the DSI will monitor all line
appearances including those on a multi-button add-on module.

Day Service refers to any configurations that you have programmed the
DSI to perform.
However, sometimes, different service is required at night. For this
reason the DSI provides a Night Service option. When the DSI is
operating on Night Service mode, all lines on the station and the add-on
module will ring whenever there is an incoming call.
The DSI will retain all configuration programming even if there is a
power failure or you unplug it. When power is restored, you may
continue to use your DSI as before.
You can attach the DSI and either the CTA-369 or CRI-376 to your MBS.
For more information about these models refer to the last page of this
guide.
To program the DSI with the CTA/CRI:
1. Apply power to the DSI and program it using the dial pad of your
MBS.
2. Disconnect power to the DSI.
3. Apply power to the CTA/CRI and program it using the dial pad of
your MBS.
4. Reapply power to the DSI.

RJ-11 jack marked STATION SET on the DSI.
2. Plug one end of the cord supplied with your DSI into the LINE jack
on your DSI and plug the other end of this cord into the STATION
SET plug on the CTA or CRI.
3. Plug one end of the cord supplied with the CTA or CRI into the LINE
jack on the CTA or CRI and the other end into the RJ-11 wall jack.
4. Plug the barrel connector of the power supply provided with the
DSI into the POWER socket on the DSI. Plug the power supply into
your wall outlet when ready to configure the DSI.
5. Plug the barrel connector of the power supply provided with the
CTA or CRI into the POWER socket of the CTA or CRI. Plug the
power supply into your wall outlet when ready to configure the CTA
or CRI.
Note:
Configuration must commence within 20 seconds of power up. See

You can connect auxiliary equipment such as loud ringers or lamps to
the AUX EQPT sockets in the DSI. With the DSI, they provide additional
signals about the status of the lines on the MBS.
The Dees Stinger 24, Model198, or Model126 is fully compatible with the
DSI.
See page 26 for instructions on how to control auxiliary equipment.
The following illustration shows how to attach the Stinger 24.
To install the Stinger 24:
1. Disconnect your MBS from the RJ-11 wall jack and plug it in to the
RJ-11 jack marked STATION SET on the DSI.
2. Plug one end of the cord supplied with the DSI into the LINE jack on
the DSI and the other end into the RJ-11 wall jack.
3. Plug a connecting line cord into the AUX EQPT jack of the DSI. Plug
the other end of the cord into the RJ-11 telephone jack on the
connecting block.
4. Connect the Stinger 24 to the connecting block making sure that the
wires are: GN to GN, RD to AD, YL to YL, and BK to BK as shown in
Fig. 5.
