The Meridian Norstar Range 

Advanced Digital Phone Systems 

from: Psyclone/mED 

Meridian Norstar is a range of digital phone systems designed to operate 
in any required configuration reaquired, as a keysystem (with a central 
operator) , or working behind a large phone system. It features 128 line- 
extension ports , access to multiple system features , loop disconnect and 
multi-frequency dialling , hi-speed+hi-quality connections.... 
This type of meridian system is a pbx not a mail system, so it is not like 
the ones many of you are used to. It does not have mail boxes , just 
extensions. This is the type of system that would be used in a office block 
or hotel, (this is the system used in my school), basically it is a real - 
time interface. There are are two types of Meridian Norstar, the difference 
between the two systems is simply that the Norstar Compact is for smaller 
organizations and the Norstar Modular is for larger ones. This variety makes 
Norstar a popular private network system. 
When i refer to "users" in this file i mean the authorized users as almost 
all of the system features in this file are only valid for the local users 
(like system operators, secretaries, or receptionists) and so may not be too 
interesting to most of you. 

The System features are : 
(in alpha order) 

Access signalling : A user can dial access and activate remote equipment 
and work within a private network. 

Accidental dissconnect protection : Calls that are accidentally cut off 
are automatically reconnected within one second. 

Analogue terminal adapter : For connection of two wire devices such as 
answering machines, fax machines, modems and external 

Answer groups :On modular systems a single key can be used to answer up 
to four extensions. 

Auto-dial keys (int. and ext.) : One button provides access to features 
or to frequently dialled numbers inside or outside 
the company. 

Auto-line select : The system selects a free line for outgoing calls 

Automatic night service : The modular automatically switches to night 
service at pre-programmed times. On Compact systems 
this is performed manually. 

Automatic fone relocation : Any fone can be moved from jack to jack , 
retaining its number and features. 

Auxiliary ringer interface : For the connection of loud bells , hooters 
or night service bells. 

Backgroud music : Audio equipment can provide music via the fones 

Busy lamp field : A user can make instant checks on extension status. 

Call barring : Outgoing calls can be barred. 

Call barring override : Allows bars to be lifted for specific destinations 
or users. 

Call duration timer : The duration of any call can be clocked via display. 

Call forward : Forward calls to alternative extensions - all calls , busy 
or no reply. 

Call forward override : Allowes person taking the forwarded calls to 
bypass call forward and contact the forwarding ext. 

Call id / call status display : Internal calls activate the display to 
show who is calling or the status of the call. 
external calls are identified by the incoming line no. 

Call logging interface : This add-on unit enables printers or call 
management equipment to be connected to Norstar systems. 

Call park : Holds a call in the system until it is picked up by a 
differant extension. 

Call pick-up : Group - A member of a group can answer another's call from 
their own fone. Trunk answer - Exchange calls can be picked 
up from any fone when a service mode is activated - ie 
night service. 

Call queuing : On modular systems incoming trunk calls are presented to 
the central answering point in the order in which they 
are were reiceived. 

Camp on busy : This enables external calls on modular to e put through 
to engaged extensions. The extension user is given a 
warning tone. The call is is connected when the extension 
becomes free. 

Centralised answering : Using a CAAP module, you can have operator 
working on modular systems. 

Confrencing : Three internal parties (or two) and one external party can 
can be connected in three way conversation. 

Delay ringer transfer : Transfers a call to another extension if not 

Dial 0 extension : Provides single button acess to a specific fone 
(usually operator). 

Dialpad feedback : Each key press is accompanied by a tone and all keyed 
numbers are displayed in screen. 

Directable call pick-up : On modular systems calls can be picked up from 
any other extension by keying in a feature code and the 
extension number. 

Direct station select : Internal calls can be made via a single reprgrmmd 
key. The busy lamp field or CAP module can be interogated 
to enhance the operation. 

Emergency telefones : If mains power fails, at least 25% or the lines on a 
Norstar system can fall back on to BS6317 phones. If this 
occurs, calls can be made and received but not switched. 

Extension lock : This allows a user to prevent others from programming 
their fone. 

Extension to Extension Calling 
Over Private Networks : Calls can be made direct between extensions at 
different sites via private networks. 

7-digit extension numbering : On Modular systems on private networks 
extensions can be numbered with up to 7 digits. 

Group listening : The handset and speaker can be be connected at the same 
time so the person can monitor a conversation or message 
without the microfone picking up any background sounds. 

Host delay : Allows time for the host system of a piggy-backed Norstar 
system to access outside lines while calls are held. 

Intrusion tone : Warns users that an internal call is about to interrrupt 
an existing one. 

Key enquiry : This allows the user to check the function, memories, and 
feature keys on each of the lines. 

Line pools : Exchange lines on private circuits can be grouped for 
outgoing access and the users can be given access to 
specified groups only. (Up to 3 pools on Compact systems 
and 15 on Modular systems). 

Liquid crystal displays : These are used on each phone to give phone and 
call details in real time and to prompt users thro the 
call handling features. 

Operator controlled phone system (pbx) 
pause/programmed release/timed break or 
earth recall/runstop : A group of features which allow Norstar systems to 
work behind a phone system which requires signals 
other than multi-frequency tones. 

Paging : *Internal - An integral paging system operates thro the fones 
speakers and can page up to 3 zones on Compact systems 
and up to 6 on Modular systems. 
*External - An external public address system can be connected. 

Prime line : A phone can be programmed to automatically select a certain 
type of line whenever the handset is lifted. 

Priority call : This allows a phone to interrupt another busy phone. The 
interrupted party can only block the intruder within 
8 seconds. 

Private lines : An outside line can be exclusively allocated to a phone. 
The only other line that can access this line is the 
Prime extension which is used to receive all unanswered 

Public phone network breakout : On Norstar systems on private networks, 
calls can be directed to breakout onto the public phone 
network via remote phone systems. 

Restriction override password : Allows a user to override all call 
restrictions on any fone via a 4-digit code. 

System memory protection : If the mains power fails, the system memory 
can be retained for 3 days. 

Tandem access : On private networks, Modular systems can switch between 

Tone on conference : A warning tone is played when another user joins a 

Volume Control : This allows separate control over the volume of the 
headset, handset, hands-free, ringing, background, 
and paging. 

Equipment Description:- 

Central Control Unit (CCU) 

Each system comprises of a wall mounted CCU and a choice of four fones. 
All features and system defaults are stored in software cartridges which 
slot into the CCU. The system is set up on installation according to your 
requirements, but you can alter the set-up yourself using an M7324 or 
M7310 phone as your programming tool on Modular systems, and an M7208, 
M7310 or M7324 phone on Compact systems. A customised box connection, 
sited by the CCU, provides simple connection of extensions to the system. 
It also provides connections for various extras and interfaces. 


M7324 - This is the fone used by the key personnel (admins). This fone has 
an optional CAP module which makes this fone the focal point of an 
operator-based system. 
M7310 - The phone for high volume users. 
M7208 - Standard. 
M7100 - Low use phone,which would sit on a desk at the end of an extesion. 

All these phones are details in a chart at the end of this document. 

All the fones have an LCD providing prompts to guide users through each 
system function. 

-Centralised Answering Position [CAP] module. 
When this is added to the M7324 is becomes an operator's position, with 
48 additional programmable keys. Modular systems can support 5 M7324's 
with 2 CAP modules each.
