Connect The Isdn Link - Cisco Webex DX70 Administrator's Manual

Cisco Webex DX70 and DX80

Introduction

Connect the ISDN Link

The ISDN Link enables a video conferencing device to use ISDN
lines for connectivity, and enables both video calls and telephone
calls over the PSTN (Public Switched Telephone Network).
ISDN Link support ISDN BRI, ISDN PRI and V.35. ISDN can be
used in addition to regular IP connectivity for SIP or H.323 calls,
or without any IP infrastructure.
ISDN Link is managed from the video conferencing device's web
interface. Sign in to the web interface and navigate to
Peripherals.
Requirements and limitations:
• The ISDN Link must be running IL1.1.7 software or later
• The video conferencing device must be running CE9.3
software or later. The video conferencing device must
have IPv6 enabled in the web interface or API in order to
communicate with the ISDN Link
• Observe the network topology in the ISDN Link Installation
Guide in order to guarantee a successful installation
• The video conferencing device and ISDN Link must be on the
same subnet. If the endpoint or ISDN Link are assigned new
IP addresses they will only remain paired as long as they are
kept in the same subnet.
• Video conferencing devices that are registered to the Cisco
Webex cloud service are not able to use ISDN Link.
