About this guide
The main objective with this guide is to describe how to
manage the Cisco TelePresence ISDN Link in automatic
pairing mode.
When using the ISDN Link in automatic pairing mode the
recommended way to manage the ISDN Link is from the
TelePresence endpoint’s web interface. The ISDN Link
must be running software version IL1.1 or later, and the
TelePresence endpoint must be running TC6.0 or later.
It is also possible to connect to the unit through the serial
port, or over the network through SSH. For details see:ISDN
Link API Reference Guide.
When using the ISDN Link in manual pairing mode you will
connect through the serial port or, if you know the IP address,
over the network through SSH. For details see:ISDN Link
API Reference Guide.

What’s new in this version
This section provides an overview of the new and changed
settings and new features in the IL1.1.2 software version. Support for G.728 and G.729 audio protocols
ISDN Link supports the G.728 and G.729 audio protocols.
These protocols can only be used if they are supported by
both ISDN Link and the endpoint that ISDN Link is paired to.
The following endpoints support these protocols in TC7.2:
• G.729: All endpoints that support ISDN Link
• Full G.728 support: C90, SX20, MX200 G2 and
MX300 G2
• G.728 support only in point-to-point calls: C40, C60 and
EX90

About ISDN Link
The Cisco TelePresence® ISDN Link is a compact appliance
for in-room ISDN and external network connectivity.
The ISDN Link provides direct connectivity for IP-to-ISDN
or IP-to-V.35 networks. It can be used as main connection
or a back up connection. Support for up to four Basic Rate
Interface (BRI) or one Primary Rate Interface (PRI) ISDN ports
and external networks (cable standards V.35, RS530, RS449,
and RS366).
Refer to the Cisco TelePresence ISDN Link Data Sheet for
information about which endpoints support use of ISDN Link.
Pairing mode
We highly recommend to use automatic paring mode.
Automatic pairing mode is supported in software version IL1.1.
The TC software on the endpoint must be TC6.0 or later.
You should use manual paring mode only if you have to
use software version IL1.0 or if your endpoint has software
version TC5.x.
NOTE: Endpoints that are paired to ISDN Link do not support
Far End Camera Control (FECC).
Changing the password
The ISDN Link is delivered with a default user account with no
password set. This user has full access rights to configuration
of the system.
NOTE: We strongly recommend that you set a password to
restrict access to system configuration.
For details see “Password protection” on page 72

Two user scenarios with IP network
User scenarios
The ISDN Link can be used with or without IP infrastructure. The TelePresence endpoint
in the illustrations for the three user scenarios is shown as a single codec without monitor,
microphone and loudspeakers. You will need a computer for configuration and maintenance of
the ISDN Link.
NOTE: The endpoint and ISDN Link must be on the same subnet. If the endpoint and/or ISDN
Link are assigned new IP addresses they will remain paired as long as they are kept in the
same subnet.
Two user scenarios with IP network
The user scenarios with IP network allows for automatic pairing mode via the TelePresence
endpoint’s web interface.
• User scenario #1: The ISDN Link and endpoint are connected through the LAN. The
endpoint and computer are connected through the LAN.
• User scenario #2 (recommended): The ISDN Link and endpoint are connected through a
direct connection. The endpoint and computer are connected through the LAN.
User scenario with no IP infrastructure
In the user scenario with no IP infrastructure, you must manually pair the ISDN Link via the
command line interface. See theISDN Link API Guide for details.
• User scenario #3: The ISDN Link and endpoint are connected through a direct connection.
The ISDN Link and computer are connected through the serial interface.
User scenario with no IP infrastructure
User scenario #3: The endpoint and
ISDN Link are directly connected.
ISDN Link
User scenario #2 (recommended): The
ISDN Link and the endpoint are directly
connected.
LAN
User scenario #1 and #2: The
computer and endpoint are
connected over LAN.
User scenario #1: The ISDN Link
and the endpoint are connected
through the LAN.
ISDN Link
User scenario #3: The computer
and ISDN Link are connected
through a serial interface.

Installing and pairing the ISDN Link
Installing the ISDN Link
Follow the instructions as described in the ISDN Link Installation Guide supplied with the unit,
or download the ISDN Link Installation Guide from our web page.
Go to:http://www.cisco.com/c/en/us/support/collaboration-endpoints/telepresence-isdn-link/
products-installation-guides-list.html
Prerequisites for pairing
• The TelePresence endpoint and ISDN Link must run the correct software. For details see
supported software versions in the Cisco TelePresence ISDN Link Data Sheet.
• The endpoint and ISDN Link must be on the same subnet.
• For optimum use, the Ethernet cable should be directly connected between the Endpoint
port on the ISDN Link, and the Ethernet port on the endpoint.
• If the ISDN Link has been previously paired to a TelePresence endpoint, make sure both devices
are properly unpaired before starting the pairing process.
• Make sure the NetworkServices SSH Mode is set to On (default) to enable access from the
web interface.
• When using auto paring, the endpoint’s IPStack must be configured to DualStack or IPv6.
The endpoint uses IPv6 link for local traffic to connect with the ISDN Link.
Pairing the ISDN Link
Pairing is a process in which the ISDN Link and endpoint communicate with each other in
order to establish a connection. The ISDN Link is shipped with pairing mode set to Auto, which
enables the ISDN Link to be discovered by a TelePresence endpoint. In both pairing modes
there is a one-to-one relationship between the endpoint and ISDN link:
• An endpoint can only use one ISDN Link.
• An ISDN Link can only be used by one endpoint.
Automatic pairing mode
In automatic pairing mode the ISDN Link can be managed from the TelePresence endpoint’s
web interface.
1. Open a web browser on your computer, enter the address (IP address or host name) of the
TelePresence endpoint in the address bar, and login.
2. From the top menu, go to Configuration > Peripherals.
3. Click the Manage ISDN Link button. This will open the ISDN Link page.
4. Click the Search for devices button.
5. Choose your ISDN Link from the list and Click the Pair button.
During the pairing process a message will display: Pairing with device: <MAC address>.
The ISDN Link is identified by the MAC Address, which is found on a label
underneath the unit.
6. When successfully paired the following text will appear on the ISDN Link page:
This TelePresence device is paired with an ISDN Link.
Manual pairing mode
In manual pairing mode the ISDN Link is managed from a command line interface through the
serial port or, if you know the IP address, over Ethernet using SSH.
Manual pairing is described in the Appendices section.

Configuring the TelePresence endpoint for ISDN
When paired to ISDN Link, the default call settings for the TelePresence endpoint can be configured
for ISDN (H320), or you can set the call protocol and call rate each time you make a call.
Setting the default call protocol to H320
Configuring the default call settings to ISDN (H320):
1. Open a web browser on your computer, enter the address (IP address or host name) of the
TelePresence endpoint in the address bar, and login.
• Navigate to Configuration > System configuration > Conference 1 > DefaultCall and set the
Protocol to H320.
• Click the Save button.
Setting the call protocol to H320 by each call
• If using a TelePresence Touch device, see: “Making a call using the Touch controller” on
page 18.
• If using a TelePresence Remote Control, see: “Making a call using the remote control” on
page 19.
• If calling from the TelePresence endpoint’s web interface, see: “Making a call using the web
interface of the endpoint” on page 20.
