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

i

expansion; do not connect anything to Ethernet Port B.

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
gateway LED behavior, on page 2.

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 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 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: 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

i

expansion; do not connect anything to Ethernet Port B.

Both ends of the Ethernet connection must be configured in the same

i

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

i

configured as auto-sensing.

6

Initial configuration

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

To establish a 1000Mbps connection, both ends of the link must be

i

configured as auto-sensing.

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

i

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 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 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.

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.

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.

Call type, select Video.

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.
