2. Introduction
2.1 Functionality
Orion-MCU provides SIP-based video/audio conferencing services for SMBs and enterprises. The
product is a ready-to-use, stand-alone network appliance. The Orion-MCU’s web-based
management system offers easy system configuration, conference creation, monitoring and
conference control in real time.
2.2 Main Capabilities
Orion-MCU offers the following major capabilities:
SIP based: Orion-MCU is a SIP-based conferencing system.
HD conferencing: Orion offers wideband HD voice and HD video in resolutions of up to 720p.
Mixing: A variety of conferencing devices are bridged by Orion’s advanced audio/video
mixing and adapting capabilities. Participants receive video and audio streams that are
adapted to their device’s media characteristics - codecs, rates, frame size and resolution.
Video/voice characteristics:
Voice codecs: G711a, G711u, G729, G722.1, iLBC, G723
Video codecs: MPEG4, H263, H264
Video resolution: Up to 720p
Conference Management: Conferences can be managed by a leader, or set as automated
ad-hoc conference rooms.
Leader Dashboard: The Orion-MCU “Leader Dashboard”, enables conference leaders to
manage the conference. Upon logging into the “Leader Dashboard”, the leader can invite
participants, modify conference parameters (mute, set dominant speaker, etc), and
revoke/disconnect participants from the conference and view conference information.
Configurable Meeting Rooms: Meeting rooms (not scheduled conferences) can be
provisioned and established, and once established, used at any time.
Multiple Access Numbers: Orion-MCU supports multiple access numbers. The Orion-MCU’s
access numbers are pre-provisioned, and are dialed by conference participants directly or
indirectly via their serving PBX.
Multiple Video Layout Options: 10 video dynamic layouts are available for equal-presence
display and 5 for dominant-based display. The layouts are modified automatically, when a
participant enters or leaves the conference.
VIP Participants: Orion-MCU allows VIP participants to join a conference without PIN code
authentication.

Orion-MCU™User Manual v.2.1.1

Registration: Orion-MCU is provisioned for registration as a SIP endpoint in the network. An
authentication option is provisioned for each registration process. SIP clients may register to
Orion-MCU’s built-in SIP registrar.
NAT Traversal: Orion-MCU provides near-end and far-end NAT traversal enabling
connectivity between entities (Orion-MCU / SIP clients) which are behind not-SIP-aware
NATs and firewalls.
Content Sharing: Orion-MCU provides content sharing, originated by a SIP client. In this case
the conferencing layout is modified to one large image which contains the content, and a
smaller image, containing the presenter’s image (currently, content sharing works only with
AVer Room system).

Orion-MCU™User Manual v.2.1.1
16
Power - The Power button is used to turn on and turn off the system. Turning off the
system eliminates the main power but maintains standby power. In order to service the system,
the server should be shut down and the AC power cord should be unplugged.
4.2.2 Control Panel LEDs
The five control panel LEDs is located at the front of the chassis and provide information related
to different parts of the system.
Overheat - When this LED is on, it indicates an overheat condition, which may be
caused by an obstruction to the airflow or because the room temperature is too
high. Check the airflow to the unit. This LED will remain on as long as the indicated
condition exists.
NIC2 - Indicates network activity on LAN2 when flashing.
NIC1 - Indicates network activity on LAN1 when flashing.
HDD - Indicates hard drive activity when flashing.
Power - Indicates power is being supplied to the system. This LED is illuminated
when the system is operating.
4.2.3 I/O Ports
Figure 4-2 shows the I/O ports of Orion-MCU appear at the rear part of the chassis.
