Repairs to certified equipment should be made by an authorized Canadian maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request the user to
disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility,
telephone lines and internal metallic water pipe system, if present, are connected together. This
precaution may be particularly important in rural areas.
CAUTION: Users should not attempt to make such connections themselves, but should contact the
appropriate electric inspection authority, or electrician, as appropriate.
European CTR 21 compliance
The equipment has been approved in accordance with Council Decision 98/482/EC for pan-European
single terminal connection to the public switched telephone network (PSTN). However, due to
differences between the individual PSTNs provided in different countries, the approval does not, of
itself, give an unconditional assurance of successful operation on every PSTN network termination
point. In the event of problem, you should contact your equipment supplier in the first instance.

1 Extra set-up notes for the Elite series VoIP
gateways
1.1 Using a ‘Wildcard’ phone number
In order to accept incoming calls on your Elite gateway you must
first of all create a dial plan which has entries for each number that
your callers will use to contact you.
e.g. Consider a simple set-up consisting of two FXS gateways.
FXS1 end FXS2 end
Local Dial Plan Set-up
Phone Number 501 401
Hunt group 5 5
Destination ID 5 5
Local Destination Channel 0 0
Remote Dial Plan Set-up
Phone Number 401 501
Hunt Group 6 6
Destination ID 6 6
Remote Destination IP IP address of FXS2 gateway IP address of FXS1 gateway
Now in order for FXS gateway 1 to call FXS gateway 2 then it uses
the dial plan tel. Number 401. But this means that BOTH gateways
must have a defined dial plan entry for 401 (i.e. on for FXS1 which
tells it how to connect to FXS2 but also one for FXS2 to accept the
call to 401). This is fine if the calling party know that they have to
dial 401 to connect the FXS2 but what if you want to accept calls
from callers who don’t know that they have to use 401? The way
round this is to create a dial plan entry which uses “.” (i.e. ‘dot’) i.e.
FXS2 end
Local Dial Plan Set-up
Phone Number .
Hunt group 5
Destination ID 5
Local Destination Channel 0
Then FXS gateway 2 will accept ANY calls.

1.2 Clearing to defaults
In the GW's memory, there are 3 portions to record the different
setting values: network setting, atpm setting and configuration
(port,coding,h323 etc.).
You need to reset (erase) each section separately. After you’ve
erased it all you then re-boot the system and the defaults are
loaded.
Following are the commands:
for dialplan: 'atpm req', 'atpm erase'
for configuration: 'config erase' 'y'
for network: 'net set fac_default' 'y'
re-boot system
1.3 How can I set-up a ‘hotline’?
A hotline means that when an FXS or FXO port is picked up (i.e. a
handset connected to an FXS port is picked up or a PSTN call is
made to an FXO port) then the gateway will autodial to another
VoIP device.
To set this feature up you need to use the CLI command
set port <port> dial_in plar [plar number]
where [plar number] is a predefined dial plan phone number.
1.3.1 Lets give an example:
You have one site with an FXO device connected to four phone
lines.
At the other site you have a four port FXS device with handsets
plugged into each port.
So first of all, at each end, you need to create two dial plans: One is
a dial plan entry which pertains to the local port on the gateway. The
second dial plan entry is to connect to the gateway at the other end
(so, this remote destination is to connect to the local destination of
the other gateway).
e.g. (remember this is just an example, the actual numbers will differ
in your set-up)

Solwise Elite VoIP Gateway User’s Guide
13
FXO end FXS end
Local Dial Plan Set-up
Phone Number 501 401
Hunt group 5 5
Destination ID 5 5
Local Destination Channel 0 0
Remote Dial Plan Set-up
Phone Number 401 501
Hunt Group 6 6
Destination ID 6 6
Remote Destination IP IP address of FXS gateway IP address of FXO gateway
To test the dial plan pick up the handset on FXS port 1 and dial 501;
the call should connect to the first port of the FXO (so you should
hear the dial tone from the PSTN line connected to the first port of
the FXO). To test a call the other way make a call to the PSTN line
on the first port of the FXO gateway. When the call comes in the
FXO gateway will pickup the call and present a second dial tone.
You should then dial 401. This should make the call forward to the
phone on the first FXS port.
Now to make it do this automatically you need to use the CLI
command (connect via the serial port using a terminal application)
set port <port> dial_in plar [plar number]
So… at the CLI prompt for the FXO gateway you need to enter the
command
set port 0 dial_in plar 401
Then do
config activate
config store
to activate and store the settings.
Then, at the CLI prompt for the FXS gateway you need to enter the
command

Solwise Elite VoIP Gateway User’s Guide
14
set port 0 dial_in plar 501
Then do
config activate
config store
to activate and store the settings.
Now do the tests again but this time you shouldn’t have to do the
dialling; the gateways should auto-dial as expected.
1.4 How can I stop the gateways ‘playing’ the DTMF tones when a call is
received?
For example, when you make a call to an FXS device on let’s say
local telephone number 203 then, after you pick the ringing handset
up at the FXS end you hear the phone number ‘203’ DTMF tones
played. If you don’t want to hear these tones (they are sent because
some caller ID devices use the DTMF tones) then you need to
instruct the dialling end device to strip the sent numbers (in this
case it would be the first 3 digits). To do this go to the Telephone
number set-up at the dialling gateway and , on the screen you use
to configure the Telephone number enter 3 (in this example) in the
field called ‘Strip Length’.
1.5 How can I configure the gateway to handle the clear forward signal (caller
disconnect)
1.5.1 So what does this mean?
When you make a PSTN call from one site to another then, when
one party hangs up a signal sent to the other parties end to indicate
to the other party that the phone call is finished. This signal is called
the ‘clear forward signal’ or sometimes the ‘call disconnect signal’.
It’s used so that devices can tell when the call is finished e.g.
answering machines. In the UK the standard signal (as used by BT)
is to reverse the polarity of the phone lines. This is different from
other countries e.g. if you are in the States and the other party
hangs up then you get sent a tone. However, in the UK being
different we use a polarity reversal /Private telephone systems as
used by UK buisnesses may use polarity reversal or the tone
method. The particular method used will depend upon PBX system
used. To test which method your PBX uses make a call from one
extension to the other and then get the calling party to hangup.
Then listen to what you hear. Do you hear a tone?

Solwise Elite VoIP Gateway User’s Guide
15
1.5.2 So what’s this got to do with VoIP gateways?
Imagine you have a site-to-site set-up of an FXO gateway talking to
an FXS gateway. So there is a call in progress from a PSTN phone
line which is connected to the first port of the FXO gateway and
then across to the FXS gateway to a phone on the first FXS port.
Now, if the call to the FXO port hangs up then the FXO gateway
needs to know this. If it doesn’t know that the PSTN call is ended
then it keeps the VoIP call to the FXS gateway open! On the other
hand. If the call to the FXS port (lets say from a remote FXO or FXS
gateway) is ended the FXS gateway needs to send a ‘clear forward’
signal to the device on the FXS port to indicate the call is ended e.g.
this might me an answering machine. So, an FXO port needs to be
able to detect a correct clear forward’ from the PSTN line and an
FXS device needs to make the correct ‘clear forward’ signal for the
handset device (e.g. this might be an answering machine). This
could be either polarity reversal or disconnect tone.
1.5.3 So how do you configure the gateway to handle the polarity reversal then?
So, let’s assume that you need to configure the gateways to handle
the UK standard polarity reversal signal.
You need to use CLI commands to configure the ports.
For an FXS gateway key-in the command…
set port <port> fxs ff_batt_rev on
where <port> is port no (0-7) and the setting should be on.
For an FXO port device the commands are
set port <port> fxo cpc_detect <value in msec>
where <port> is port no (0-7) and <value in msec> is the time taken
for the polarity reversal. A typical value would be 30 i.e. it takes
30mS for the polarity reversal event.
You also need to key-in…
set port <port> fxo batt_rev_times <number of times>
this command is to define how many line reversals the FXO port
needs to receive before accepting the ‘clear forward’: In the UK this
value should be ‘2’.
Also,
set port <port> fxo loop_det_db <value in msec>

Solwise Elite VoIP Gateway User’s Guide
16
This is a value to ensure that false polarity reversals are not
detected. A good value is 20 (10 less then the cpc_detect value).
After entering the commands you need to do
config activate
config store
to activate and store the settings.
1.5.4 So how do you configure the gateway to a disconnect tone correctly then?
So, let’s assume that you need to configure the FXO gateways to
handle the US style tone disconnect signal.
By default your gateway automatically detects the disconnect tone
however it may need to be ‘tuned’ to correctly detect the specific
tone your system produces. I.e. the cadence (the tone might go
‘beep-pause-beep-pause’ so you need to tell the gateway the
duration of the ‘beep’ and the duration of the ‘pause’) and power
level (how loud it is).
The first stage is to tell your FXO gateway to analyse the disconnect
tone it receives on it’s FXO port.
The basic method it to set the gateway into debug mode (to display
the tone analysis) then make a call to the FXO gateway and then,
after the gateway has answered make a call from the gateway to
another port on the same gateway. After the forwarded call is
connected then you hang up. The gateway will then print out the
tones it detects. You then take these figures and enter them into the
gateway configuration.
1.5.4.1 Entering debug mode on the gateway
In console mode enter the following commands:

1.5.4.2 Wiring Up to do the test with an FXO/FXS gateway
In the example above the test procedure is going to be make a call
from phone 1234, through the PBX to the FXO port (number 1233).
If you are connecting the FXO port directly to a phone line then just
dial the phone line that the FXO port is connected to. Then, after the
FXO port has answered the call, dial number 101 which is the
phone connected to the FXS port. Thus you have a call from 1234
to 1233 and then to 101. Then, after the call is routed hang up
1234. You should then see tone detection results appear on the PC
terminal.

In the example above the test procedure is going to be make a call
from phone 1234, through the PBX to the FXO port (number 1233).
If you are connecting the FXO port directly to a phone line then just
dial the phone line that the FXO port is connected to. Then, after the
FXO 102 port has answered the call, dial number 101 which is a
second FXO port. You should then here the dial tone from the PBX
on line 1236. (Yet again if you are connecting the FXO ports directly
to phone lines you should here the phone line dial tone from the
second line.) Now make a third call to phone 1235. Thus you now
have a call from 1234 to 1233, then to 101 and then to 1236 and
finally to 1235! Then, after the call is routed hang up 1234. You
should then see tone detection results appear on the PC terminal.
