ISDN Link

iSDN link is used in conjunction with a single endpoint to allow inbound and outbound iSDN calls. With

TC6.0 and il1.1 you can use the video systems web interface to pair the iSDN link with a codec. You

can also use the web interface to manage and upgrade the iSDN link.

When you access the web interface of a TC6 system, you can easily see if it is paired and configured

with an iSDN link. On the System information screen, you can find a H320 section under the Sip/H323

sections. in addition, Diagnostics will indicate if an iSDN link is detected.

if there are any configuration issues on the iSDN link, you will see a red lED on the iSDN link and

a warning on the System information screen on the web interface of the paired TC6 system. in the

example below there is an error on the pri interface. red alarm and l2 indicate a low level iSDN issue.

in this case the cable was physically unplugged from the iSDN link.

To manage the system, change the configuration, check the status or upgrade the iSDN link you can

do this from

Configuration -> Peripherals

and click

Common Issues

if you see the error message "Not Sip-registered to H320 peripheral" ensure that Sip is enabled. On the

web interface select

Configuration -> System Configuration -> Network Services -> SIP Mode ->

Check that Sip outbound is not enabled either on the iSDN link or the video system you are pairing

the iSDN link to.

Microphones

Series has more selection of inputs and you can choose to use the handset, headset, Bluetooth or the

built-in microphone on the system.

if the far-end cannot hear you, you should check the following:

•

Microphone is not muted. MX, C20, SX20 can be muted and unmuted from a button on the

microphone or Touch panel. You can see the microphone status on the

section of the web interface.

•

Microphone is physically connected to the system (C Series, SX, MX).

•

Correct input is selected: phone, headset, built-in, Bluetooth (EX Series).

•

Try another microphone and cable (C Series, SX, MX), or headset/handset/Bluetooth device

(EX series).

•

if you are using the remote control, you can check the audio input levels and see if the microphones

are picking up sound. To do this go to

Under the VU you will see a meter showing activity on the microphones.

•

if you have a C40, C60 or C90 you can download the TC Console application. Under the audio

section enable the VU meter to check the microphone inputs live.
