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).  
!

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.  
FFor information about the behavior of the ISDN port LEDs, refer to Table 1, ISDN  
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.

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

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.

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.

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

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.

Troubleshooting and technical support information  
Refer to this section if you are experiencing difficulties with the ISDN gateway.  
Ensure that you have followed the instructions in this guide when installing and  
configuring the ISDN gateway.  
Calls fail to complete  
If outgoing calls fail to complete, check that you have configured the ISDN gateway  
and all other equipment correctly, paying particular attention to the number you are  
trying to call. Remember that endpoints may be busy when you call them.  
Using the event log to help solve a problem  
Unless you are experiencing a problem, all event logging sources should be set to the  
default, which is Errors, warnings and information. For more information about  
configuring the event log, refer to the online help accessible from the web interface.  
You can use the event log to produce debugging information to assist technical  
support in solving your problem. However, we recommend that you only alter the  
setting of the event log under the guidance of technical support representatives. In  
particular, it is not recommended that you indiscriminately turn on event logging  
sources.
