1. INTRODUCTION
GENERAL
DESCRIPTION 1.01 The Business Set is designed for direct connection, through a
non-loaded subscriber loop pair, to the Northern Telecom DMS-250,
DMS-100, or Meridian SL-100 Digital Switching systems.
1.02 The M5009 Basic Business Set is loop powered and will work
with a maximum loop length of 4,572 m (15,000 ft) of 26 AWG
standard twisted pair telephone wires, subject to Line Engineering rules
(297-2011-180).
1.03 The service provided by the Business Set substitutes low-level
signals passed over a half-duplex, above-voiceband signaling channel
for the traditional loop signaling (dial pulse) or inband tone signaling
(DTMF tones) on a conventional subscriber loop. In addition to
signaling and supervision, messages on the above-voiceband signaling
channel include signals for implementing the many special features
available on the Business Set.
1.04 The M5009 Business Set offers a choice of selected key and
system features; it has 3 fixed keys, a dial pad consisting of 12 fixed
keys, 8 programmable feature and/or directory number keys with LCD
indicators, 1 programmable feature key without an LCD indicator (key #
9, in topmost position) and is equipped with a speaker for alerting
tones, on-hook dialing and intercom.

M5009 BASIC
OPERATIONS
Making a Call and
Accessing Features 3.01 The M5009 Business Set can be used to make voice calls and
operate selected DMS-100 or Meridian SL-100 features. All supported
features can be accessed via the keys provided on the M5009 Business
Set. For further details on software requirements, refer to
297-2011-100 and 297-1001-310 respectively. Dial pad, DN, and
feature key layout is shown in Fig. 1-1.
Note: The M5009 Business Set can not be assigned as a
maintenance set.
3.02 Detailed descriptions of how to dial and how to answer a call,
and how to access the various features are given in the User Guide
which is shipped with each telephone. Refer to the User Guide before
attempting to operate the Meridian M5009 Business Set.
Peripheral Equipment 3.03 The M5009 Business Set interfaces with the business set
(6X21AC) line card in the Line Concentrating Module (LCM) of the
DMS100/Meridian SL-100 Central Office (CO) equipment. The 6X21AC
supports one business set per line card.
Acoustics 3.04 A speaker is used for alerting tones, call monitoring (on-hook
dialing) and intercom.
Power 3.05 The M5009 Business Set is entirely loop powered by a balanced
440 Ohm battery feed from the switching equipment. The switch battery
voltage supplied to the loop is nominally 52 V dc, with a minimum of
42.75 and a maximum of 56 V dc.
3.06 The current drawn from the loop is 16±1 mA when the set is
active. The current drawn from the loop when the set is inactive is 8.4
±0.8 mA.
DESCRIPTION OF
FEATURES
Keys 3.07 The M5009 Business Set (Fig. 1-1) is characterized by the
following:
(a) There are 15 fixed keys with no LCD indicators, assigned as:
•Release key (1)
•Hold key (1),
Page 3-1

PRACTICE 297-2011-201
•Volume up/down key (1), and
•Dial pad keys (12).
(b) There are eight (8) assignable key/LCD indicator pairs.
(c) There is one (1) assignable key (# 9) without a functioning LCD
indicator.
3.08 LCD indicators used with DN keys support four (4) key/LCD
states as follows:
FUNCTION LCD STATE
Idle Off
Ringing (or Flashing at 60 interruptions
“Feature Pending”) per minute (IPM)
Hold Winking at 120 IPM
Active On
Basic Features 3.09 Every Business Set has the following basic features:
(a) Automatic Prime DN selection: allows the user to select the
prime DN (i.e., the DN assigned to the 1st key) by going
off-hook to answer a call without pressing a DN key.
(b) On-hook Dialing: allows a call to be dialed by selecting a line
and dialing the number without lifting the handset. The handset
must be lifted once the called party answers.
(c) Listen On Hold: can be activated by pressing the hold key
(associated LCD flashing), placing the handset back in its cradle,
and re-selecting the line to be monitored (associated LCD on).
(d) Alerting Tones: Warble tone sounds when telephone is
on-hook, 500 Hz local buzzer tone sounds when telephone is
off-hook.
FEATURES OPERATION
Fixed Keys 3.10 The fixed keys on the M5009 Business Set provide these
permanent functions: call Hold, call Release, Volume Control, and
dialing.
3.11 Dialpad. Before a call is established, no tone-feedback is
provided when the dialing keys are being pressed. After a call has been
Page 3-2

PRACTICE 297-2011-201
established, end-to-end signaling using CO generated DTMF tones is
enabled.
3.12 Hold. The HOLD function has two modes of operation, manual
and automatic. With the user engaged in a call, the call can be put on
hold either by pressing the HOLD key or by pressing another DN key.
In either case the DN LCD changes from ON to “winking” and the user
is free to answer or make another call.
3.13 Release. The RLS (release) key performs a similar function as
going on-hook, i.e. when pressed, it terminates a call. The DN LCD
associated with the released call changes from the ON state to the OFF
state, but the status of the Set remains “off hook” to the switch.
3.14 Volume Control. The loudness of any sound which comes
through the speaker (i.e. ringing, dial tone, busy tone and on-hook
monitoring) is controlled by one key with two toggle positions.
Tapping the key at the right hand side will increase the volume, tapping
it at the left hand side will decrease it. The volume changes in steps,
each time the key is released.
3.15 The volume for alerting tones can only be adjusted while
alerting is in progress and is automatically stored at the new level. The
on-hook monitor volume level can be adjusted while monitoring.
Storing of this level for further calls can be accomplished by depressing
both sides of the volume toggle switch simultaneously after the required
level has been reached. If this is not done, the monitoring volume level
will return to the previously stored setting for the next call.
3.16 If the M5009 Business Set is disconnected from the line and
then reconnected, all volume settings will return to the original default
values (mid-point setting for alerting tones and minimum setting for
on-hook monitoring).
3.17 The feature keys can be assigned a subset of a number of
features. Examples of some of the available features are given as
follows:
•Automatic Dial (AUD)
•Automatic Line (AUL)
•Busy Override (EBO)
•Call Basic Queuing (CBQ)
•Call Forward (CF)
•Call Park (PARK)
•Call Pickup (CPU)
Page 3-3

PRACTICE 297-2011-201
•Call Waiting (CWT)
•Directed Call Park (DCP)
•Directory Numbers (DN)
•Group Intercom (GIC)
•Individual Business Line
•Intercom (ICM)
•Make Set Busy (MSB)
•Malicious Call Hold (MCH)
•Message Waiting (MWT)
•Multiple Appearance Directory Numbers (MADN)
•Privacy Release
•Ring Again (RAG)
•Set Busy Indicator (SBI)
•Speed Calling (SCS, SCL, or SCI)
•3-Way Calling/Call Transfer (TWC/CXR)
•6-Port Conference
3.18 Local Tones. A locally generated buzzer (500 Hz) tone is
utilized for call waiting and off-hook alerting. All other telephony tones
are provided by the switching equipment from a Tone Card.
3.19 Tone Characteristics. The various tones heard on the
M5009 Business Set are defined as follows:
TONE CHARACTERISTIC
Ringing Interrupted warble tone, typically 2
seconds on, 4 seconds off
Busy Interrupted tone, 1 second on, 1 second
off
Call Waiting Short burst of buzzer tone (500 Hz), 10
second intervals
Confirmation Three short bursts of tone, not repeated
(informs user that feature requested has
been implemented. This tone is present
only when the feature access code is
dialed)
Dial Continuous tone (consisting of 2
frequencies)
Reorder Interrupted tone, 1/2 second on, 1/2
second off (informs user of unavailable
feature, all trunks busy, illegal code etc.)
Ring Again
Page 3-4

PRACTICE 297-2011-201
Short burst of buzzer tone (500 Hz), once
only (informs user that previously busy
station or trunk line is now free)
Special Dial Three short bursts of dial tone, followed
by continuous dial tone (informs user that
dialed feature, e.g. call forwarding, has
been activated and further digits [ e.g.
station directory number to which calls are
to be forwarded] can be dialed).

4. INSTALLATION PROCEDURES
M5009 BUSINESS SET
Unpacking or Packing 4.01 Use proper care while unpacking any M5009 Business Set.
Check for damaged containers so that appropriate claims can be made to
the transport company for items damaged in transit.
4.02 If a telephone has to be returned to the factory, ascertain that it
is packed in the appropriate container as shown in Fig. 4-1 to avoid
damage during transit. Remember to include all loose parts (e.g. cords
and handset) in the shipment.
Preparations 4.03 Installation requires plugging in the cords to the TELADAPT*
jacks that are accessible at the base of the telephone. Cord restraining
tabs are provided for security (See Fig. 4-2). Make the necessary
connections to the Teladapt connecting block (Tip [ + ] green lead and
Ring [ -] red lead), and plug the line cord into the Teladapt jack.
Proceed in steps as given in Chart 4-1.

5. VERIFICATION PROCEDURES AND MAINTENANCE
VERIFICATION TEST
ROUTINES 5.01 These are acceptance tests. If the criteria outlined in the Line
Engineering Rules (297-2011-180) are observed, impulse noise,
background noise and crosstalk compatibility problems are unlikely.
The loop check should be performed, the telephone installed, and the
Tip/Ring polarity should be checked before attempting to establish a
communication path to another telephone and going through the
different call routines (enabled features) while observing and verifying
the responses at the set. Key/LCD Indicators can be tested with the
“Station Ringer Test” in accordance with Chart 5-1.
MAINTENANCE 5.02 Maintenance of the Business Set is restricted to replacement of
the set and other field replaceable items as tabulated in Part 6 (Ordering
Information).
LOOP CHECK 5.03 Loop and linecard tests must be performed at the switching
equipment (ref. 297-2011-180). It is assumed that loops and linecards
have been checked out prior to the installation of any Business Sets.
5.04 Verify that the loop resistance is ≤1230 Ohm, and that the loop
loss is ≤24 dB at 8 kHz.
POLARITY CHECK 5.05 The M5009 Business Set is polarity sensitive. If problems arise
when the set is to be put into service, proceed as follows:
(a) If the set does not respond (no dial tone) after 20 seconds, check
polarity of the tip and ring leads (tip + , ring -).
(b) If tip and ring lead reversal does not solve the problem, restore tip
and ring to original polarity and change the set.
STATION RINGER
TEST 5.06 The Station Ringer Test (SRT) tests the hardware of the M5009
Business Set and can be performed by the installer or repairman at the
site with no involvement of the Central Office personnel.
Test Set-Up 5.07 With the handset on hook and all LCD indicators off, press the
prime directory number (prime DN) key and dial the 3 to 14 digit access
code. The access code consists of a one to seven digit number which is
assigned by the telephone company according to local preferences,
followed by the last two to seven digits of the prime DN assigned to the
telephone to be tested. In North America, the access code usually
consists of the number 57, followed by the last five digits of the prime
DN. If the required digits are dialed incorrectly, a REORDER tone will
sound which makes it necessary to press the RELEASE key and start
again. If all digits are correct, all LCD indicators at the set, except the
LCD associated with key 9 (topmost key on telephone) will light up. The
test can now proceed in accordance with Chart 5-1.
Page 5-1

PRACTICE 297-2011-201
Note: The system will not attempt to restore any LCD to its pre-test
state. The LCDs will be OFF at the end of the test, with features in the
same state as before the test. A background audit restores all feature
indicators at its next occurrence (audit intervals are switch and load
related). Any newly activated features after termination of the test
procedure will be indicated normally. No incoming calls can be
received for the duration of a Station Ringer Test. In order to prevent
prolonged line blockages, this test is limited to a 7 minute interval
after which the line will automatically be restored to normal and the
test terminated.
