1. Introduction
The Aristel 4x4 PABX & 2Way Router is both a mini PABX and a Router. It is
easy to install, and is capable of handling complex routing functions.
As a mini PBX, the system has 4 exchange line and 4 extension ports, plus an
external music or message on hold port.
Incoming line calls can be routed to one or more phones and outgoing calls
can be programmed to use specific line ports ( trunks ) by use of dial plans.
Thus, the 4x4 can be connected to fixed wireless terminals and VoIP adaptors
to take advantage of low or no cost calls. It can also be connected behind a
large PBX, as sub PBX, to provide flexibility and expandability.
Phone functions include, internal extension calls, external calls, call
transfer, call pickup, call forward, hotline etc. Most of these functions can
be programmed using one of the extension phones. However, a PC may be
connected to the PABX Router system and all customer configurations and
routing programming can be carried out using supplied Setting Tool Software.
The Aristel 4x4 PABX & 2Way Router comes as a “plug and play”device. All
that is required is to power up the equipment and connect 1-4 analogue (SLT)
phones to Tel ports and 1-4 exchange lines or other devices such as analogue
telephone adaptors (ATAs ) or Fixed Wireless Terminals (FWTs ) to the Line
ports.
Un programmed, the extensions assume numbers 11, 12, 13 and 14. Incoming
calls on Line 1 will ring extension 11 and Line 2, extension 12 etc. Outgoing

calls from any extension can pick up any line. There is no need to dial 9 or 0
for outside line access. Simply dial the external number.
Additional trunk lines can be terminated on the respective Line ports and
activated through phone programming or PC programming.
2. Power Setting
The power requirements of the device are AC230V±10% or AC110V±10%
50/60HZ. In the base of the device there is a power select switch. The 4x4
is supplied with the switch set to 230 volt.
If your input power supply is AC230/240V, you should leave the power
select switch as Fig.1.
WARNING: DO NOT SET THE SWITCH TO 110V IN AUSTRALIA
AS IN FIG. 2

2.1 Music on Hold
The PABX has chime as internal source for music on hold.
An external music source can be connected to the system using the
cord provided for that purpose.. Any external Music on hold source
should only be connected to the system using a suitable LIU unit.

3.Main functions and Operation
3.1 Internal Call
Pick up the handset, dial *followed by the extension number.
Example: Your Extension number is 11, and you want to call Extension
14.
Pick up the handset of Extension 11 and dial *14.
Extension 14 rings, and it displays “8811”. The additional number “88” is a
prefix, indicating it is a direct call. For a transferred call the prefix is “0088”
3.2 Incoming call
If there is an incoming call, the called extension will ring. Pick up the
handset and answer the call.
3.3 Call Pick-up
An incoming call to an extension may be picked up from another extension.
To pick up an incoming call of another extension go off hook and dial * 9
and talk to the calling party.
3.4 Outgoing call
To call an outside party, say 9544 7696, simply dial that number and listen to ring tone.
When the called party answers start your conversation. Hang up when finished.

3.5 Call Transfer
An established call can be transferred to another internal extension. There
are two types of call transfer, (i) Blind transfer (ii) Consultation and
transfer.
Blind transfer (Unannounced transfer):
1. Assume A, an outside party called an internal extension, B. While Aand B
are talking B decides to transfer the call to another extension , called C.
2. To transfer the call, B presses flash/recall. At this moment Extension B
hears dial tone and the outside party hears Music on Hold. Then B dials
xx , where xx is the extension number of C.
3. If the operation was successful, B will hear ring tone and hangs up at
once.
4. C rings, andAhears music while waiting for the connection.
5. C lifts the handset and answers the transferred call ofA.
6. C also can transfer the call to another extension in the similar fashion.
7. In the step 4, if the C does not reply within 25 seconds, the system rings
back B. If B does not answer within 30 seconds, the call gets
disconnected.
Consultation transfer:
1. Assume B is an extension. A is an outside party. A called B and A and B
are talking. B wishes to consult C and then transfer the call.
2. B presses flash/recall, hears dial tone, dials the extension number of C.
3. If all of the above operations are correct, B will hear ring tone. Extension
B does not hang up in this case.
4. While C rings,Ahears music while waiting for the connection.
5. C lifts the handset to talk to B. A still hear music while waiting for the
connection.
6. At this time either B or C can hang up. For example, if Bhangs up first, C
gets connected to A. If C hangs up, B gets connected withA.
7. In the step 4, if the C does not answer within 25seconds, the system calls
back B. At this time, B can pick-up the call and speak to A. If B does not
respond within 30 seconds, the connection disconnects automatically.

Note
a) If error tone “Du, Du” is heard after pressing flash/recall, it indicates the
system is busy. You can press flash/recall again to go back to the called party.
b) While transferring a call, if you dial an invalid number, the system sounds 3 short
error tones. During that time you can again dial another number for transferring.
c) While transferring a call, and the called phone is busy, the system will sound a 15
sec error tone. Then, you can press flash/recall to reconnect with the outside line.
You may retry that extension or dial another.
Important
System flash time at default is 80 x 10 = 800 ms , (maximum flash time.)
Therefore, a telephone flash key needs to be typically set to 100ms.
In Aristel Smart phones and Multiphones a flash setting of 010 x 10 = 100ms works well.
On all other ordinary phones a quick tapping of the cradle switch can give a loop break of
nearly 500ms.and that works fine.
3.6 Call Forwarding.There are two types of Call forwarding:
(i) Internal.
(ii) External.
For either type, call forwarding is immediate.
In the case of Internal call forwarding, Pick up the handset and dial,
* # 8 * xx where xx is the call forwarded extension number.
You will get a confirmation tone at the end.
To cancel Call forwarding dial * # 8 #
In the case of external Call forwarding, pick up the telephone handset
and dial * # 8 xxxxxxxxxx # , where xxxxxxxxxx is the external number.
To cancel external call forwarding, dial * # 8 #
Please note, there will be no indication that an extension has been
call forwarded.
3.7 Hot Line
Hotline is a feature that allows an extension ( programmed for hot line ) to
automatically dial another extension or an external party, immediately the
handset goes off hook. There are many applications for this feature.
Connecting a Fax machine, EFTPOS machine, Door phone to extension ports
or making a baby call are examples of hot line.
