Introduction
297–2011–214 02.01 Standard February 1999
General description
The 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.
The M5316 is partially loop powered and requires the use of a 16 V AC
external power supply.
The service provided by the M5316 substitutes low-level signals over a half-
duplex, above-voice band (8 kHz) signalling channel for the traditional loop
signalling (dial pulse) or inband tone signalling (DTMF tones) on a
conventional subscriber loop. In addition to signalling and supervision,
messages on the above-voice band signalling channel include signals for
implementing the many special features available on the M5316, as well as
display characters.
The M5316 offers a choice of selected key and system features—it has 3
fixed keys, a dial pad consisting of 12 fixed keys, 16 programmable
feature/directory number keys with LCD indicators (including the two
assigned feature keys Handsfree and Mute), and is equipped with a speaker
for alerting tones, Handsfree dialing and intercom.
The alphanumeric display module is mounted at the rear top edge of the
telephone and is hinged so that the viewing angle can be adjusted physically
to reduce glare and maximize the contrast. The maximum display capacity
of the display screen is 2 rows of 24 characters each.

1-2 Introduction
297–2011–214 02.01 Standard February 1999

Basic features
Every Business Set has the basic features described below.
Automatic Prime Directory Number (PDN) selection
Allows the user to select the prime DN (i.e. the DN assigned to the first
feature/line key) by going off-hook to answer a call without pressing a DN
key.
On-hook dialing
Allows the user to select a line and dial the call without lifting the handset.
Once the party answers, the handset must be lifted to speak.
Listen on hold
Activated by pressing the Hold key (associated LCD flashes), placing the
handset back in its cradle, and re-selecting the line to be monitored
(associated LCD on).
Alerting tones
Warble tone sounds when the telephone is on-hook, 500 Hz local buzzer tone
sounds when the telephone is off-hook and the associated LCD indicator
flashes.
Additional features
In addition to the basic features, the M5316 provides the following features:
LCD Screen
Two rows of 24 alphanumeric characters can be displayed.
Handsfree calling
Allows the user to carry on a telephone conversation without lifting the
handset (applies to both the originating and answering a call).
Microphone muting
Allows the user to listen to a call without the other party being able to hear
any sound from the user.
Automatic Answer Back (AAB)
This is an optional feature which can be provided with or without a dedicated
feature key. When installed, AAB allows an incoming call to the PDN to be
answered automatically after one ring. Conversation takes place through the
integrated handsfree functions without manually controlling the telephone.

3-6 Operations and features
297–2011–214 02.01 Standard February 1999
Features operation
The fixed keys on the M5316 Business Set provide these permanent
functions:
• dialing
• call Hold
• call Release
• Volume control
Dial pad
Before a call is established, no tone-feedback is provided when the dialing
keys are being pressed. After a call has been established, end-to-end
signalling using CO generated DTMF tones is enabled.
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
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.
Release
The (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 ON to OFF, but the status of the Set remains off-
hook to the switch.
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 increases the
volume while tapping it at the left-hand side decreases it. Each time the key
is pressed, the volume level changes one step, as shown on the volume bar
display (there are seven volume levels).
The volume for ringing 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 and automatically stored while monitoring.
Volume levels can also be pre-set to a new level in program mode.
If the M5316 Business Set is disconnected from the line and then
reconnected, all volume settings return to the original factory default values
