About the ISDN gateway

The ISDN gateway is a high performance video gateway which enables ISDN network
connectivity for the Codian IP-based video infrastructure products as well as
IP-based endpoints.

Installing the ISDN gateway

IMPORTANT: Before installing the ISDN gateway into the MSE 8000, and

connecting the power supply, you must read the safety information at
http://www.codian.com/safety.htm

Although blades are hot-swappable parts, you must only remove one

!

blade at any time. Remove the power from the MSE 8000, if you need to
remove more than one blade at a time.

Before hot-swapping a blade, shut down the blade using the web

!

interface. Do not shut down a blade during a software upgrade or if the
blade is processing.

For information about powering the MSE 8000, refer to the Getting Started Guide
that accompanied the chassis.

Install the ISDN gateway into the MSE 8000 chassis

You must install either a blade or a blanking blade in each of the ten

!

positions in the chassis.

The Supervisor blade must be installed into slot 1 of the MSE 8000

!

chassis.

1 Remove the blade or blanking blade from the slot into which you are going to

install the ISDN gateway:
i Using a No.1 Phillips screwdriver, loosen the screws in the retaining latches

with an anti-clockwise quarter turn.

ii Open both retaining latches on the front of the blade or blanking blade.

When open, a retaining latch is at a 90
the blade.

iii Slide out the blade or blanking blade.

2 Open both retaining latches on the front of the ISDN gateway. When open, a

retaining latch is at a 90
3 Slide the ISDN gateway into the blade slot (as shown in Figure 2) until it stops.
4 Simultaneously close both retaining latches on the blade (thereby engaging the

connectors at the rear of the blade) to secure in the chassis as shown in Figure 3.

Connecting the ISDN gateway

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.

Step one: 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 two: 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 information about the behavior of the ISDN port LEDs, refer to Table 1, ISDN
gateway LED behavior, on page 2.

Initial configuration

Initial configuration

Step one: 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.

To configure Ethernet Port A, log in to the Supervisor’s web interface and go to

Hardware > Blades. For more information about configuring the port, refer to the

online help accessible from the Supervisor’s web interface.

Step two: Assign an IP address to the ISDN gateway

You can use the Supervisor’s web interface to configure the IP addresses of all blades
installed in the MSE 8000. Note that all blades are supplied with DHCP enabled. You
can either keep this setting or assign static IP addresses to a blade from the
Supervisor’s web interface. To view or configure the IP address of the ISDN gateway,
log in to the Supervisor and go to
the ISDN gateway, go to

Hardware > Blades and click the IP address of that blade.

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.

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.

Troubleshooting and technical support information

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
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.
