Introduction
297–2011–208 02.01 Standard February 1999
General description
The M522 add-on module can be attached to the M5216 or M5316 Meridian
Business Set to provide extra feature/line keys (see Figure 1-1). When one
M522 is connected, 22 additional feature/line keys are available to the
Meridian Business Set. If required, you can also connect one additional
M522 add-on module to increase the number of additional feature/line keys
to 44.
The M5216/M5316 Meridian Business Set is designed for direct connection
(through a non-loaded subscriber loop pair) to the Northern Telecom DMS–
10, DMS–100, DMS–250, or Meridian SL–100 Digital Switching systems.
For more information regarding the M5216 or M5316, refer to the
publications cited in the section “Other documentation”.

Peripheral equipment
The M522 connects to the M5216 or M5316 Meridian Business Set. The
M5216/M5316 interfaces with the business set (6X21AC) line card in the
Line Concentrating Module (LCM) of the DMS–10/DMS–100/Meridian SL-
100 Central Office (CO) equipment. The 6X21AC supports one business set
per line card.

Introduction 1-3
297–2011–208 02.01 Standard February 1999
Physical characteristics
The add-on module comes in three different colours which match the
M5216/M5316 colours:
• Chameleon-grey (Engineering code NT4X43AA)
• BTS light-grey (Engineering code NT4X43BA)
• Black (Engineering code NT4X43CA)
The Mean Time Between Failure (MTBF) for the M522 is at least 100 years.

Chapter 2
Specifications
297–2011–208 02.01 Standard February 1999
The following specifications govern the performance of the M522 add-on
module and the environmental conditions under which this performance is
achieved.
Environmental and safety considerations
The M522 meets the Canadian and U.S. mandatory interconnect
requirements for Telephone Equipment.
Temperature
In the Operating State, the M522 temperature range is 0°C to 50°C
(32°F to 122°F).
In the Non-Operating State, the M522 temperature range is -20°C to 70°C
(-6°F to 158°F).
Relative Humidity
20% to 95% (non-condensing). At temperatures above 34°C (93°F), relative
humidity is limited to 52mbar of water vapour pressure.
Electromagnetic Interference
The radiated and conducted electromagnetic interference meets the
requirements of Subpart J of Part 15 of the FCC rules for class B computing
devices.
Atmospheric pollution
The M522 is designed to withstand normal atmospheric conditions
throughout its life and during shipment and storage as defined in the
International Electromechanical Commission (IEC) document 50 (salt, mist,
atmospheric dust, sulfur dioxide, and hydrogen sulfide exposure).

2-2 Specifications
297–2011–208 02.01 Standard February 1999
Vibration
The M522 is designed to work to specifications after being subjected to the
following vibrations in each of three orthogonal directions for 90 minutes:
• Vibration frequency of 5 Hz to 500 Hz
• Maximum half displacement 0.35mm (0.014 in)
• Maximum acceleration 15m/s/s.
Shock When packaged, the M522 is designed to withstand normal handling during
shipment.
When unpacked, the M522 is designed to withstand accidental dropping
during normal use, without sustaining damage, when dropped on any face or
corner from a height not exceeding .75m (30 in).
Power The M522 is powered through its connection to the M5216/M5316. The
M5216/M5316 is partially loop powered by a balanced 440 Ohm battery feed
from the switching equipment. The switch battery voltage supplied to the
loop is nominally 52 VDC with a minimum of 42.75 VDC and a maximum
of 56 VDC. Under normal conditions the polarity must be negative on the
Ring lead with respect to the Tip lead.
The current drawn from the loop is 16 ±1mA when the set is active. The
current drawn from the loop is 10 ±1mA when the set is inactive.
The M5216/M5316 also requires a 16 V AC external power supply rated at
375 mA. During a power failure, the Handsfree and RT clock functions are
not available.

Operations and features
297–2011–208 02.01 Standard February 1999
Basic operations
The M5216/M5316 Meridian Business Set can be used to make voice calls
and operate selected DMS–10, DMS–100, or Meridian SL–100 features.
Each installed M522 expands the number of keys available for feature/line
installation by 22. All supported features can be accessed using keys
provided on the M5216/M5316 and the M522. For further details about
software requirements, refer to NTP 297–2011–100 and NTP 297–1001–310
respectively.
Before attempting to operate features installed on the M522, please refer to
the M5216 Meridian Business Set User Guide or the M5316 Meridian
Business Set User Guide. This document is shipped with the set and contains
instructions for making calls and how to use various features.

3-2 Operations and features
297–2011–208 02.01 Standard February 1999
Features operation
The M522 add-on module has 22 keys which can be installed with lines or
features. Once installed with features and/or lines, the keys and LCD
indicators function as those found on the M5216/M5316.
There are 22 LCD indicator segments (half diamonds) on the M522. When
there is activity on keys located on the left side of the M522, a left half
diamond lights on the LCD. When there is activity on keys located on the
right side of the M522, a right half diamond lights on the LCD. A summary
of M522 keys and indicators is provided in Table 3-1.

297–2011–208 02.01 Standard February 1999
Programmable key numbers and the datafill
The 22 feature keys available on the M522 add-on module are assigned key
numbers to enable the switch to identify individual key functions. The
numbering scheme used for key assignments is shown in Figure 3-1.
The presence of the M522 is transparent to the process of data filling the
M5216/M5316 set.

Installation
297–2011–208 02.01 Standard February 1999
Installing the M522
Before installing the M522 check the package contents as described below.
To install the M522 follow Procedure 4-1.
Unpacking or packing
Use proper care while unpacking the M522. Check for damaged containers
so that appropriate claims can be made to the transport company for items
damaged in transit.
If a telephone or add-on module must be returned to the factory, make sure it
is packed in its original container to avoid damage during transit. Remember
to include all loose parts in the shipment (e.g. cords, AC transformer, and
handset).
Before you begin the installation
Ensure that you have the following items before you start the M522
installation:
• one M522 add-on module (two if connecting two M522 modules)
• an extended wedge-shaped base to join the M5216/M5316 to the M522
(use the single extended base to join one M522 module to the
M5216/M5316; use the double extended base to join two M522
modules—see Chapter 6 “Replacement parts” for ordering information).
• one long (320mm) ribbon cable
• one short (178mm) ribbon cable (only required for connecting two
M522 modules)
• one screw (pozi-drive)
• key labels
• plastic key caps

297–2011–208 02.01 Standard February 1999
Procedure 4-1
How to install the M522 (continued)
Step Action
6Insert one end of the long ribbon cable (320mm) into receptacle C
as shown in Figure 4-2. The cable connector is polarized (see
Figure 4-3) to ensure the connector is properly seated in the
receptacle.
Figure 4-3
Polarized connection detail
7Insert the other end of the long ribbon cable into receptacle D as
shown in Figure 4-2. Slide the ribbon cable underneath the
restraining tabs H so that it is not twisted and so that the
ribbon cable avoids the screw mount. This placement ensures
that the cable will not be pinched or squeezed by the screw once
the extended base is attached.
8If you are adding a second M522 (2) to the telephone set, use the
short ribbon cable (172 mm) to connect it to the M522 already in
place. On the M522 (1) already connected to the telephone set,
insert one end of the short ribbon cable into receptacle E. On the
second M522 (2), insert the other end of the ribbon cable into
receptacle F. Make sure the ribbon cable is not pinched or
twisted.
