Connecting the ISDN gateway
Before you start
IMPORTANT: Before installing the ISDN GW 3201 (ISDN gateway), you
must read the safety information at http//www.codian.com/safety.htm
Your ISDN connection
To reduce the risk of fire, use only 26 AWG or larger telecommunication
line cord.
Outside North America
Check with your network provider to ensure that your incoming ISDN PRI line is
terminated in an NTU/CSU (Network Termination Unit/ Channel Service Unit). If
it is not, then seek their advice regarding the provisioning of such a device. Do not
connect the ISDN gateway directly to an external ISDN line.
Within North America
If your network provider has not terminated all of your incoming ISDN PRI lines
with an NTU/CSU, Codian recommends that you install a suitably approved CSU to
protect the ISDN gateway from damage by surges on your ISDN PRI lines.
If you do not install a CSU between the incoming ISDN PRI lines and the
ISDN gateway, then the ISDN gateway must be installed in a restricted
location as defined by EN, IEC and UL60950. This is defined as an area
intended for qualified or trained personal only with access controlled by a
locking mechanism such as a key.
If you do not install a CSU between the incoming ISDN PRI lines and the
ISDN gateway, then you are required to connect the ISDN gateway to a
protective earth as follows:
Connect a protective earth cable (not supplied) to the terminals on the
rear of the chassis marked with the earth symbol
Connect the other end of this cable to a true earth.
.
The earth terminal accepts two M4 screws on a 16mm (5/8") spacing for
use with a two hole copper lug (such as the Panduit LCD10-10A-L).
!
4
Connecting the ISDN gateway
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.
Only connect to Ethernet Port A. Ethernet Port B is reserved for future
expansion; do not connect anything to Ethernet Port B.
i
Step three: Connect to the ISDN ports
The ISDN gateway uses a standard RJ48C ISDN interface for each PRI port.Use a
single straight-through STP patch cable to connect each PRI port on the ISDN
gateway to your ISDN connection.
For D-channel signaling to be established, the ISDN gateway must have
i
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.
5
Initial configuration
Step one: Connect to the console port
1
2
Ensure power is connected to the ISDN gateway and the Status LED is green.
Connect the console port of the ISDN gateway to the serial port of your PC
using the blue RJ45 to DB9 console cable supplied.
3
Use a serial terminal program, such as Secure CRT or HyperTerminal, to
connect to the ISDN gateway. Set your terminal software to the following
settings:
Baud rate:
Data bits:
Parity:
Stop bits:
Flow control:
38400
8
none
1
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.
i
i
Both ends of the Ethernet connection must be configured in the same
way. For example, either configure both ends of the link to be auto-
sensing 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.
i
6
Initial configuration
1
2
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>
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
To establish a 1000Mbps connection, both ends of the link must be
configured as auto-sensing.
i
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,
omit this step.
ꢀ
To assign a static IP address, use the following command:
static <IP address> <netmask> <default gateway address>
<DNS server address>
If you do not have a DNS server, use 0.0.0.0 as the DNS server IP
address.
i
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 0.0.0.0
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.
7
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).
2
Click Change log in and enter the user name adminwith no password.
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
i
link, and provide the required user information.
Step two: Set up the ISDN interfaces
1
2
In the web interface, go to Settings > ISDN.
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.
4
5
Click Apply changes to save any changes you have made to the configuration.
Restart the ISDN gateway (this is only necessary if you changed the ISDN
configuration). To do this:
i
Go 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
7
When the ISDN gateway has restarted, log in to the web interface again, and go
to Settings > ISDN ports.
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.
8
9
Click Apply changes to save your configuration changes to the ISDN port.
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.
8
Configuring the ISDN gateway
Step three: Configure an H.323 gatekeeper
If you have H.323 endpoints, using an H.323 gatekeeper can make it easier for callers
to make their call. You can configure the ISDN gateway to use an external gatekeeper
or its own built-in gatekeeper.
To configure the use of an H.323 gatekeeper, go to Settings > Gatekeeper. Typically
you may want to add a Dial plan prefix for voice calls (for example 9) and another for
video calls (for example 8).
For more information refer to the online help topic: “Configuring gatekeeper
settings”.
Step four: 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.
Below are some simple configurations for dial plan rules.
IP to ISDN dial plan setup
This example allows IP codecs to dial (via a gatekeeper) the ‘phone number of the
destination endpoint, using a prefix of 9 for audio calls and 8 for video calls. It
assumes that you require both video and voice calls to be made from your IP network
to ISDN and that you have set up dial plan prefixes 8 and 9 on the ISDN gateway’s
Settings > Gatekeeper page.
1
2
In the web interface, go to Dial plan > IP to ISDN and click Add rule.
For Condition, select Called number matches and enter the correct match for
example 9(D*).
3
4
5
For Action, select Call this number and enter $1.
For Call type, select Telephone.
Leave the other values unchanged. Click Add rule to add the rule to the dial
plan.
6
Repeat steps 1 to 5 to create a second dial plan to accept and forward the video
calls with the correct format in Called number matches, for example 8(D*)
and for Call type, select Video.
9
ISDN to IP dial plan setup
Options 1 and 2 will automatically handle both voice and video calls.
Option 1 - This example assumes that you have a PRI line that has 100 numbers (00
to 99) associated with it and that all your endpoints are registered to a gatekeeper
with registrations in the range 5900 - 5999.
1
2
Go to Dial plan > ISDN to IP, and click Add rule.
For Condition, select Called number matches and enter the correct match for
example D*(DD), which will match the last 2 digits of the dialed number. To
match the last 3 digits, use D*(DDD).
3
4
5
For Action, select Call this number and enter 59$1.
For Call type, select Video.
Leave the other values unchanged. Click Add rule to add the rule to the dial
plan.
Option 2 - This example assumes that you have a PRI line which has 1 number
associated with it but you require access to multiple endpoints on the IP side. When
you dial you will be greeted by the ISDN gateway's auto attendant and using TCS-4
or DTMF you can dial the extension of the IP endpoint, if known.
1
2
3
4
5
Go to Dial plan > ISDN to IP, and click Add rule.
For Condition, select Match any called number.
For Action, select Enter the auto attendant + TCS-4.
For Call type, select Video.
Leave the other values unchanged. Click Add rule to add the rule to the dial
plan.
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 — and the dial plan
rule syntax — are explained in greater detail and with supporting examples in the
online help accessible from the web interface.
