             Glenayre GL3000 paging and voice retrieval system
	    ---------------------------------------------------

		Background info/blurb from Glenayre's web page
	       ------------------------------------------------

	Glenayre Technologies Inc. is a worldwide provider of personal 
communications products and systems serving the paging, cellular, PCS, 
telco, voice processing and point-to-point wireless service provider markets.
Glenayre's net sales exceeded $390 million in 1996 and the company employs 
approximately 2,100 people worldwide.  blah blah blah



Paging Terminal Components
--------------------------


1 - Trunking: 
	The trunking sub-system is comprised of circuitry designed to 
interface external audio based input devices such as telephones to the 
terminal.  When a paging terminal is called from a telephone, the telephone 
central office connects the calling party to the terminal through what is 
known as a trunk circuit.  For now it is important to understand that the 
terminal must be connected to the public switched network via trunk. The 
number of trunk circuits that the terminal can support coupled with the 
types of services being offered, is probably the two single most limiting 
factors that determine the amount of subscribers that can be supported by a 
paging terminal. Glenayre offers paging terminals as small as 8 trunks to 
192 trunks.

2 -  Subscriber Database
	The subscriber database is where the information about individual 
subscribers is stored (duh).  This database contains information such as the
format of the pager, the individual code needed to signal the pager, the 
channel the pager is listening to, and whether or not to record a voice 
message, etc etc etc.  The database may also contain information not used by
the terminal to process the call, but can be used by the operator of the 
system to help run his business.  Information such as account numbers, call 
counts, and activation dates are all there. The database has management 
functions associated with its design that allow for the system operator to 
search for almost any specific item or combination of items stored in the 
database. Data that is to be input into the database, and any search 
functions that are to be implemented, are done via the user port sub-system. 
	
	The subscriber database is comprised of slots or positions that 
represent a telephone number or address in memory.  Some pagers have multiple
functions that may require more than one telephone number.  *Having a 
subscriber database of 10,000 numbers does not necessarily mean the terminal 
will support 10,000 subscribers*.  It just means that there are 10,000 
positions in memory to store information about subscribers.  As the service 
type of certain subscribers may require up to 10 different numbers, and 
trunking is an important factor in determining subscriber capacity, a 10,000 
number terminal may support as few as 1,000 subscribers. Glenayre has paging 
terminals rangeing in number capacity from 1,500 to 1,000,000. The database 
is normally maintained in ram for quick access. Copies of the database are 
maintained on a hard disk back-up unit in case of power failures or other 
faults that could disturb the info.                              

3 - Voice Storage
	In the GL3000 you will either have a voice buffer card or it will be 
hard drive based, the newer ones are hard drive based.  The voice storage 
sub-system is used for almost any operation by the terminal that involves
spoken messages. Services such as voice paging, voice prompts, voice message 
storage and retrieval, and numeric retrieval, all require the use of the 
voice storage sub-system.                                                      

4 - Outputs
	The output-subsystem takes the information, that was stored in the 
database concerning how to alert a pager, as well as any information such as 
display or voice messages that were input into the terminal from the user
port or trunk sub-systems, and formats the information in the proper way for 
transmission on the correct channel.  The output section may also be 
required to queue until there is time available on the channel to send the 
page. The output section then monitors the amount of pages it has in queue 
to determine if the system is becoming too lagd. If the output senses a 
congested condition, it may give a command to the trunking sub-system to stop
 taking in new pages, and return a busy signal to the calling party. After 
the output senses the congested condition has been cleared, it will send a 
new command to the trunking sub-system to continue with its normal call 
processing routines.  In other words "flow control".
	
	The generation of the information that is sent to the transmitter is 
performed by an encoder.  An encoder is required for every channel that is 
to be controlled by the terminal.  An encoder can handle from 1 to 500,000 
subscribers depending on the type of services offered to the and the paging 
protocol. The amount of subscribers that an encoder can support is totally 
dependent on the amount of air-time available on an RF channel.  Different 
pager formats and different types of service, such as Tone and Voice paging, 
require different amounts of air-time to send a page to a subscriber. The 
output encoder may also be called upon to act as a part of the transmitter 
control device.

5 - User Ports
	Basicly this is for the Operator to monitor and make changes on the 
GL3000.

6 - Power Supplys
	Only thing you really need to know is that it's pretty much like a 
computer power supply but with different voltage settings.



GL3000 Logging features
-----------------------


	There are quite a few logging features for the GL3000 and here they 
are.  BTW, any of these may be turned on or off, they are not usually all 
on though as it would make it kind of a heavy load.

1 - Trunk Activity Monitoring
2 - Digital Trunk Call Flow Logging
3 - Link Channel and UOE Activity Logging
4 - Serial Port Activity Logging
5 - Network Logging
6 - RTC Activity Logging
7 - Alphanumeric Logging
8 - Packet Logging



The GL3000 Voice Mailbox
-----------------------------


	Well this section is probobly why you were reading this, thats why I 
put it at the bottom so you might learn something about the system instead of
'what button do I press?'.  Anyways, on with the show.

1 - Getting into                    
        Well this should be fairly easy since every one I have encountered is
passwordless by default unless the subscriber sets it up themselves.  So 
basicly all that you have to do is dial up the mailbox number you'll get the 
computer greeting then after it says its thing you will here the subscribers 
own greeting (one thing I never liked about it).  But before you hear the 
subscribers greeting press '0' to access the mailbox, if it has a password it 
will ask for it, if it doesn't it will let you right in telling you if you 
have any new/old messages.

2 - Commands
	Ok here are the commands once you are inside the mailbox.

[Main]
*  - Help message
2  - Delete message you just heard
3  - Play newest message  
4  - Play oldest message
5  - Replay message just heard

     |_ 10 - Return to main               
17 - Change access code or caller password (optional)                                  |_ 3  - Enter new access code
     |

     |
     |_ 10 - Return to main
     |
     |_ #  - After entering access code 


Conclusion
----------
	Well hopefully you have read from the beginning to the end so-as to 
learn something about what your doing and not just how to be a leet voice 
mail box 'hacker'.  Alot of info was gathered from manuals about the GL3000 
and from personal experience.
	Also I did not go very far in depth about the inner workings of the 
GL3000 such as the newer Wireless Messaging Transfer Protocol which is what 
Glenayre will be slowly migrating to in the future as I did not feel the urge 
right now so maybe another text will suffice when I have more time.
