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
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
2
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° angle perpendicular to the front of
the blade.
iii Slide out the blade or blanking blade.
Open both retaining latches on the front of the ISDN gateway. When open, a
retaining latch is at a 90° angle perpendicular to the front of the blade.

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
expansion; do not connect anything to Ethernet Port B.
i
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.

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
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
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 Hardware > Blades. To access the web interface of
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.
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.
