Cisco TelePresence ISDN Link
Installation guide
Automatic pairing mode
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 an endpoint. When pairing is completed the
ISDN Link is dedicated to the endpoint it has been paired with. The automatic pairing mode
provides an improved user experience, but requires that the endpoint supports this feature.
Supported versions
Automatic pairing mode is supported in software version IL1.1, and later, for Cisco
TelePresence MX-, SX-, EX-, and C-Series running TC6.0, and later. If using software earlier
than TC6/IL1.1 see the About manual pairing mode section.
NOTE: The endpoint and ISDN Link must be on the same subnet. The Ethernet cable should
be directly connected between the Endpoint port, on the ISDN Link, and the Ethernet 1 port,
on the endpoint.
Start pairing
1. Open a web browser, enter the address of the endpoint, and login.
2. From the top menu, go to Conguration > 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 identied by the MAC Address, which is found on a label
underneath the unit.
6. When sucessfully paired the following text will appear on the ISDN Link page:
This TelePresence device is paired with an ISDN Link.
Checking the status of the ISDN Link
Navigate to Conguration > Peripherals > Manage ISDN Link > ISDN Link Conguration.
After having congured the
ISDN Link, check this area to
see the status of the pairing.
