Linux device offers web, video, audio conferencing

Sep 16, 2013 — by Eric Brown — 853 views

RHUB Communications is shipping a videoconferencing and web collaboration appliance that runs embedded Linux on an AMD G-Series processor. The TurboMeeting 210 (TM210) appliance is equipped with multiparty web, video, and audio conferencing functionality, as well as remote support, remote access, and webinar applications.

RHUB announced the TM210 with few details back in April as a replacement for its earlier, low-end TM200 appliance. The TM210 and other RHUB appliances run the company’s Linux-based TurboMeeting software stack, which was upgraded to version 5.0 in July, and competes with products such as WebEx. The company claims to have more than 2 million end users. TurboMeeting supports 6-in-1 conferencing, namely: web, video, and audio conferencing, plus remote support, remote access, and webinar applications.

The main difference from one 6-in-1 model to the other is capacity, such as the number of concurrent meetings and attendees. The TM210, for example, supports up to four meeting rooms and 20 concurrent participants.

Also in April, RHUB announced the TM270 appliance, which replaced an earlier TM260. The device supports roughly twice the number of users as the TM210, or up to 10 meeting rooms and 50 concurrent participants. There’s also a new TW 100 device specifically aimed at running webinars of 100 or fewer attendees.

Other RHUB 6-in-1 appliances include the TM-510 (20 rooms, 100 participants), and the TM-560 (50 rooms, 200 participants). There are also three 1U rackmount models that offer pre-integrated LDAP support. The rackmount TM-600 supports up to 100 meeting rooms and 300 concurrent participants, while the TM-800 supports 200 rooms and 500 participants, and the TM-1000 can handle up to 1,000 rooms and 3,000 participants.

RHUB can record conference audio, web cam, and screen-sharing information on both PCs and Macs in a synchronized file, which can be converted to multiple standard formats including Flash, WMV, and AVI, says RHUB.



The TM210 runs Linux on an unstated AMD G-Series processor. The fanless desktop appliance measures 9.0 x 6.0 x 1.2 inches, weighs 4.9 pounds, and runs on 10 Watts using a DC 12V 5A with external adapter, says RHUB. A gigabit Ethernet port is provided, as well as an unstated complement of flash memory. Judging by the photo, a serial port and a hard disk drive (HDD) are also part of the package.

Audio conferencing can use both external PSTN and internal VoIP technology, and both can be used in any meeting, says RHUB. The PSTN system is said to be “free conference,” and provides local numbers in 24 countries.

The appliance can be plugged into a firewall for secure, internal meetings, as well as a DMZ perimeter network for public-facing meetings. LDAP integration is said to be optional.

The TM210 uses a concurrent usage license rather than a named user license, and can support any number of users, limited only by concurrent access. The default on the TM210 is two meeting rooms and 10 concurrent participants, but this can be expanded to four rooms and 20 participants.

In an email to LinuxGizmos, RHUB co-founder and CEO Larry Dorrie confirmed that all of the company’s conferencing appliances run the same Linux-based TurboMeeting software.
