Connecting the ISDN gateway
Before you start
Your ISDN connection
Check with your network provider to ensure that your incoming ISDN PRI line has
been terminated in an NTU/CSU. If it has not, then seek their advice regarding the
provisioning of such a device. Do not connect the ISDN gateway directly to an
external ISDN line.
Step one: Connect power
Connect the power connector on the rear of the unit to the power supply using the
supplied power cable. (There is no On/Off switch.)
Step two: Connect to Ethernet Port A
Connect an Ethernet cable from Ethernet Port A to an Ethernet switch (rather than a
hub, to minimize interference from other devices on the network). The Ethernet
port is a 10/100/1000 Mbps auto-sensing connection.
Before installing the ISDN GW 3200 (ISDN gateway), refer to the
Operating guidelines on page 18 and Safety warnings on page 18.
To maintain connectivity with the ISDN network, the ISDN gateway must
be connected to the ISDN network via an in-building NTU (Network
Termination Unit) or CSU (Channel Service Unit).
The ISDN gateway only supports ISDN with 64k channel size.
Only connect to Ethernet Port A. Ethernet Port B is reserved for future
expansion; do not connect anything to Ethernet Port B.
Connecting the ISDN gateway
7
Step three: Connect to the ISDN ports
The ISDN gateway uses high-density ISDN connectors to provide two ISDN
interfaces on a single RJ45 connector. This high-density connector means that you
must use the supplied Y cable (see Figure 3) to connect the ISDN gateway to your
ISDN connection.
For information about the behavior of the ISDN port LEDs, refer to Table 1, ISDN
gateway LED behavior, on page 4.
Figure 3: Y cable
1 Connect the single end of the supplied Y cable to the port labelled 1 2 on
the ISDN gateway.
2 Connect the white and blue plugs on the double end of the Y cable to your ISDN
connection. If you have a GW 3210, connect only the white plug (leaving the
blue plug unconnected); if you have a GW 3220, connect the white plug and the
blue plug to your ISDN connection.
You must use the Y cable, even if you plan to connect just one of the
ISDN interfaces. Using a standard straight-through cable will not work.
The Codian ISDN gateway may not be compliant with EMC
(Electromagnetic Compatibility) standards if you use a cable other than
the supplied Y cable.
For D-channel signalling to be established, the ISDN gateway must have
found and synchronized with the ISDN network clock. In some
installations, you may have to explicitly request your ISDN provider to
enable the network clock before the link will be established.

Connecting further ISDN ports
If you have a model GW 3240 or GW 3280, you will have been supplied with more
than one Y cable. Connect each further cable following the method outlined above.
Extending the Y cable
You have been supplied with two RJ45 to RJ45 in-line couplers per Y cable. Use
these if you need to extend the Y cable to reach your ISDN connection. If you need
to do this, connect the coupler at the double end of the Y cable and extend using a
standard (8-core) straight-through cable. For example, in the case of a GW 3210,
connect the coupler to the white plug at the double end of the Y cable, and a straightthrough cable between the in-line coupler and the ISDN connection.
Initial configuration
9
Initial configuration
Step one: Connect to the console port
1 Ensure power is connected to the ISDN gateway and the Status LED is green.
2 Connect the console port of the ISDN gateway to the serial port of your PC
using the blue RJ45 to DB9 cable supplied.
3 Use a serial terminal program, such as HyperTerminal, to connect to the ISDN
gateway. Set your terminal software to the following settings:
Baud rate: 38400
Data bits: 8
Parity: none
Stop bits: 1
Flow control: none
4 Press Enter and the following command prompt appears on the terminal:
ISDN-GW:>
Step two: Configure Ethernet Port A settings
The default setting for the ISDN gateway Ethernet ports is auto-sensing mode. If the
switch ports to which you connect the ISDN gateway are not also set to auto-sensing
mode, then you need to configure the ISDN gateway Ethernet ports to use the same
speed and duplex mode.
Only connect to Ethernet Port A. Ethernet Port B is reserved for future
expansion; do not connect anything to Ethernet Port B.
Both ends of the Ethernet connection must be configured in the same
way. For example, either configure both ends of the link to be autosensing or configure both ends to operate at the same speed and duplex.
To establish a 1000Mbps connection, both ends of the link must be
configured as auto-sensing.
10
1 To configure Ethernet Port A, enter the following for auto-sensing mode:
ethertype auto
or to configure a speed and duplex, use the following command:
ethertype <10|100> <half|full>
2 To display the current configuration and status of the Ethernet ports, enter:
status
For example, to configure a full-duplex 100Mbps link, enter:
ethertype 100 full
Step three: Assign an IP address to the ISDN gateway (optional)
The default setting for the ISDN gateway is to use DHCP to obtain an IP address. You
can assign a static IP address if you prefer or if a DHCP server is not available.
If you want the IP address of the ISDN gateway to be assigned by your DHCP server,
do not complete this step.
To assign a static IP address, use the following command:
static <IP address> <netmask> <default gateway address>
<DNS server address>
For example, to assign an address of 192.168.1.2 where the default gateway is at
192.168.1.1, enter:
static 192.168.1.2 255.255.255.0 192.168.1.1 192.168.1.1
Step four: Discover the IP address of the ISDN gateway
1 To display the current status of the IP address, enter: status
If you have DHCP enabled on your network and you are allowing the ISDN
gateway to acquire its address using DHCP, the IP address that has been acquired
by Ethernet Port A will be shown; if you have assigned a static IP address, that is
the address that will be shown.
2 Make a note of the IP address. You will use this to access the web interface of the
unit.
To establish a 1000Mbps connection, both ends of the link must be
configured as auto-sensing.
If you do not have a DNS server, you must use the IP address of your
default gateway in place of the DNS server IP address.
Configuring the ISDN gateway
11
Configuring the ISDN gateway
Step one: Log in to the ISDN gateway
All administration of the ISDN gateway is performed via the web interface. To log in
to the ISDN gateway:
1 Use your browser to navigate to the IP address of the ISDN gateway (to discover
the IP address, refer to the previous section).
2Click
Change log in and enter the user name admin with no password.
Step two: Set up the ISDN interfaces
1 In the web interface, go to Settings > ISDN.
2 Select the
ISDN interface type to match that of your installation; E1 is typically
used in the UK and mainland Europe, T1 (USA and Canada) in North America,
and T1(Japan) in Japan.
3 Complete the other settings as required by your network, referring to the online
help for further information.
4Click
Apply changes to save any changes you have made to the configuration.
5 Restart the ISDN gateway (this is only necessary if you changed the
configuration). To do this:
iGo to
Settings > Shutdown, and click Shut down ISDN GW.
ii Confirm that you want to shut down the ISDN gateway.
iii Click
Restart ISDN GW.
6 When the ISDN gateway has restarted, log in to the web interface again, and go
to
Settings > ISDN ports.
7 Complete the settings for ISDN Port 1 as required by your network, referring to
the online help for further information. Note that all ISDN ports on the ISDN
gateway are enabled by default.
8Click
Apply changes to save your configuration changes to the ISDN port.
9 If required, configure another ISDN port by selecting the port number from the
numbered links at the top right of the ISDN port configuration page.
Codian recommends that you change the admin account to use a
password as soon as possible. To do that, go to Users, click the admin
link, and provide the required user information.
12
Step three: Configure the dial plan
The default behavior of the ISDN gateway is to reject all calls. You must configure a
dial plan to allow permitted calls to be placed.
There are a number of different ways in which you can use the dial plan. For
example, you can use the dial plan to link specific bandwidths to certain prefixes,
thereby enabling users to use the correct bandwidth for an IP to ISDN call. You can
also use the dial plan to enable the ISDN gateway to join incoming ISDN calls to the
correct conference on an MCU. These dial plan configurations are explained in
greater detail and with supporting examples in the online help accessible from the
web interface.
The simplest configuration is to create a dial plan that will:
connect any IP to ISDN call that has been routed to the ISDN gateway to the
number that the caller has dialed (using any free enabled port)
connect any ISDN to IP call to the auto attendant of your MCU
To do this:
1 In the web interface, go to
Dial plan > IP to ISDN and click Add rule.
2For
Condition, select Match any called number.
3For
Action, select Call with the original called number.
4 Leave the other values unchanged. Click
Add rule to add the rule to the dial
plan.
5Now go to
Dial plan > ISDN to IP, and click Add rule.
6For
Condition, select Match any called number.
7For
Action, select Call this number and enter the IP address of your MCU.
8 Leave the other values unchanged. Click
Add rule to add the rule to the dial
plan.
Configuring the MCU
13
Configuring the MCU
If you are connecting the ISDN gateway to a Codian MCU, refer to this section for
information.
Adding the ISDN gateway
To simplify the making of outgoing calls by ISDN, you can configure your MCU. To
do this:
1 Using your web browser, navigate to the web interface of the MCU.
2Go to
Gateways.
3Click
Add new H.323 gateway.
4 Enter a name for the gateway, such as Codian ISDN gateway, and specify the IP
address of the ISDN gateway. Leave all other fields unchanged.
5Click
Add H.323 gateway.
Configuring endpoints
The simplest way to call ISDN endpoints from your MCU using the ISDN gateway is
to define pre-configured endpoint definitions for any endpoints you wish to call.
To define pre-configured endpoint definitions:
1 Using your web browser, navigate to the web interface of the MCU.
2Go to
Endpoints.
3Click
Add H.323.
4 Enter a name for the endpoint, such as CEO ISDN phone.
5In the
Address field, type the phone number of the endpoint.
6 Select the gateway you have just added for
H.323 gateway. Leave all other fields
unchanged.
7Click
Add endpoint.
You can now call out to this endpoint as described in the next section.
14
Making calls
When you have set up the Codian ISDN gateway, and MCU if appropriate, you can
make calls via the ISDN network.
Calling in by ISDN
If you have configured the dial plan as described in Step three: Configure the dial plan
on page 12, endpoints calling the telephone number of the ISDN gateway will, when
the call is completely established, be forwarded to the auto attendant of the MCU.
From here they may use the Far End Camera Controls (FECC) of their endpoint to
navigate the menus and join conferences as normal.
Calling out by ISDN
To call an endpoint connected by ISDN, invite it into a conference using the predefined endpoint. To do this on the Codian MCU:
1 Using your web browser, navigate to the web interface of the MCU.
2Go to
Conferences and select the conference you are interested in by clicking
its name.
3Click
Add participant and select the ISDN endpoint from the list of pre-
configured endpoints. Click
Add selected.
A call will be placed through the ISDN gateway to the desired endpoint.
