2.2 Excellent HD Video
The HUAWEI VP9035A supports a conference access rate of up to 4 Mbit/s and provides
superior video quality in the industry.
The HUAWEI VP9035A supports video coding protocols of H.261, H.263, and H.264, and
video resolutions of 720p (1280 x 720 pixels) with a frame rate of 30 fps, 720p (1280 x 720
pixels) with a frame rate of 60 fps, 1080i 50/60 field, and up to 1080p of 30fps. In addition, it
is compatible with standard-definition (SD) video formats, such as the Common Intermediate
Format (CIF) and 4CIF.
The definition of 1080p video doubles that of 720p video. With sharp edge processing and
vivid color, the video is fine and smooth, thus bringing you into a completely new visual
experience and enabling you to enjoy every detail in the HD video. When 720p video with a
frame rate of 60 fps is selected, movements can be displayed vividly and smoothly.
By using Huawei proprietary technologies, such as VideoIntensifier and ViewProcessing, and
the latest H.264 codec, the HUAWEI VP9035A provides a much higher video compression
ratio. Therefore, it can provide clearer, smoother, and more vivid video under the same
bandwidth. When the call bandwidth is equal to or higher than 512 kbit/s, the video resolution
can reach 720p with a frame rate of 30 fps. When the call bandwidth is higher than 1 Mbit/s,
the video resolution can reach 720p with a frame rate of 60 fps, 1080i 50/60 field, or 1080p
with a frame rate of 30 fps.
2.3 Perfect HD Audio
The HUAWEI VP9035A supports dual-audio-channel broadband audio that complies with
AAC-LD and HWA-LD. In addition, it is compatible with multiple narrowband audio codec

The AAC-LD and HWA-LD audio protocols use a sampling rate of 48 kHz. In this case, users
can hear all the sounds with a frequency lower than 22 kHz and conferences are presented
vividly.
By using the dual-audio-channel technology and working with the Huawei HUAWEI
VPM210 microphone array, the HUAWEI VP9035A provides an excellent all-round audio
quality to let you feel the breath and heartbeat of another participant. In addition, the
HUAWEI VP9035A provides high-fidelity stereo audio with a sound hack effect to enhance
the lifelike reality of a conference.
By using the automatic echo cancellation (AEC), automatic gain control (AGC), and
automatic noise suppression (ANS) technologies, the HUAWEI VP9035A provides users with
clear full-duplex digital audio.
The HUAWEI VP9035A supports the multi-channel audio mixing function. Different
channels of audio data are mixed to one channel for the transmission to a remote site. In
addition, the volume of each audio input or output channel can be adjusted separately. Users
can adjust both the input gain of each audio input and the volume of the each audio output.
2.4 Superb HD Dual-Stream Technology
2.4.1 Standard H.239 HD Dual-Stream
The HUAWEI VP9035A supports the standard H.239 protocol. Therefore, it can transmit two
independent channels of video streams. After the Video GraphicsArray (VGA) output
interface on a computer is connected to the HUAWEI VP9035A, both the conference video
and the content displayed on the computer, such as a slide, a Word document, a flash, or an
HD picture, can be transmitted to a remote site simultaneously, thus meeting the requirements
of different conference scenarios, such as training or medical consultation.
The HUAWEI VP9035A supports a computer resolution of up to 1280 x 1024 pixels, which is
the highest H.239 Content resolution in the industry. In this case, the characters of 6.5 points
in a Word document can be displayed clearly.
2.4.2 Powerful 720p Dynamic Dual Stream
By using the powerful hardware platform of the HUAWEI VP9035A, two channels of 720p
videos can be encoded and decoded. The H.239 Content can be used to display the video of a
Blu-ray Digital Video Disc (DVD) or an HD film played on a computer. Both video and
desktop contents can be dynamically displayed with a frame rate of 30 fps. Thus, the
requirement of displaying dynamic dual stream can be met.
2.4.3 Innovative Technology of Dynamic Adjustment of Streams
The HUAWEI VP9035A supports dynamic adjustment of streams. When two channels of
streams are transmitted, users can adjust the bandwidth of each channel based on the
maximum bandwidth and the required bandwidth. In addition, users can also dynamically
close or open a channel of streams during a conference. When the transmission of the H.239
Content stops, the bandwidth used for transmitting the H.239 Content is automatically applied
to the main stream, thus providing the video with a higher bit rate. After the transmission of
the H.239 Content starts again, the bandwidth of the H.239 Content is recovered automatically.

Users can dynamically adjust the bandwidth of streams. In this case, the network bandwidth
resources can be fully used and a better conference quality can be achieved.
During conferences, users can dynamically set the video format (to sharp or smooth) and
the bandwidth for sharing presentations to receive the best possible experience.
2.4.4 Flexible Dual-Screen Display
The HUAWEI VP9035A supports the dual-screen display. In this case, users can use two
display devices simultaneously. One device displays the video of the remote site (participants
of a conference). The other device displays the contents used at the conference (H.239
Content on a computer). Thus, the video and the contents can be transmitted and displayed
synchronously, facilitating user operations.
2.4.5 Abundant Split-Screen Modes
The HUAWEI VP9035A supports multiple split-screen modes. Users can simultaneously
display two or three channels of videos that are from the remote main stream, remote H.239
Content, local main stream, or local H.239 Content on one screen.
Through a special video consolidation technology, the size of each channel of the video on the
split-screen display can be modified as required to meet the requirements of different
applications when a user has only one display.
2.4.6 Intelligent Display Compatible with Both 16:9 and 4:3
Standards
The HUAWEI VP9035A supports both 16:9 and 4:3 standards. It is compatible with different
output display devices and can automatically adapt to a display device, which facilitates the
use in an actual situation and protects the video quality from being affected. Thus, the current
investment is protected to the maximum.
2.5 Powerful and Easy-to-Use Built-in MCU
The HUAWEI VP9035A has a built-in MCU. This MCU enables users to hold multipoint
conferences that can be simultaneously attended by up to four 720p HD video sites and three
audio-only sites, meeting the requirements of small and medium sized enterprises for holding
small conferences. The built-in MCU can be cascaded with other built-in MCUs or
large-capacity MCUs to hold large conferences with several hundreds of participants,
removing the capacity limitation on a single MCU.
The built-in MCU of the HUAWEI VP9035A possesses powerful full-adaptation capability.
The MCU automatically negotiates the audio-visual capability of the conference with each
participating site, allowing participants at each site to have the best conference experience
available. HD sites, SD sites, H.323 sites, and Session Initiation Protocol (SIP) sites can
attend the same conference. Depending on the number of participating sites, the built-in MCU
can automatically adjust the continuous presence mode so that the video of each site can be
displayed in continuous presence. The built-in MCU also supports continuous presence for
each port. This function means that each site participating in a multipoint conference can
independently choose which sites (excluding the local site) to view in continuous presence,
improving conference experience.

The built-in MCU of the HUAWEI VP9035A enables users to invite multiple sites to join a
conference using the Web interface or the remote control. Sites can also call into a conference
held on the built-in MCU. With the need to set parameters (such as conference protocols and
site capability) eliminated, the HUAWEI VP9035A makes a perfect choice for
videoconferencing for small and medium sized enterprises.
2.6 Powerful Line Backup
2.6.1 (4)E1+IP Backup
The HUAWEI VP9035A provides interfaces for (4)E1 and Internet Protocol (IP) lines. When
a (4)E1 line is used, an IP line is used as a backup line; when the IP line is used, the (4)E1 line
is used as a backup line. During an ongoing conference, when a line is faulty, the HUAWEI
VP9035Adetects the fault and automatically enables the backup line. In this case, the ongoing
conference is not affected, thus ensuring the service reliability. The line is switched
automatically. The HUAWEI VP9035A provides the easiest and most stable line backup
policy.
2.6.2 2E1+2E1 Backup
When 4E1 lines are used for network access, the HUAWEI VP9035A provides the 2E1+2E1
access mode. In this case, when two lines are used as the active lines, the other two lines are
automatically used as the backup lines. During an ongoing conference, if any of the two active
lines is disconnected or both active lines are disconnected simultaneously, the backup lines
can take over seamlessly without affecting the ongoing conference. Thus, effective service
reliability is guaranteed.
2.7 Comprehensive Network Access Capability
2.7.1 Abundant Line Interfaces
The HUAWEI VP9035A provides multiple line interfaces, such as 4E1, E1, and IP line
interfaces. In addition to a mandatory IP interface, the other interfaces are accessed through an
interface board and support plug and play. These interfaces can fully meet different access
requirements. Also, users do not need to pay for unnecessary line interfaces.
By working along with the ViewPoint 8660 MCU, the HUAWEI VP9035A can implement the
4E1 bound access through special patented technologies, which is a breakthrough of the E1
bandwidth bottleneck. In this case, users can enjoy the high-bandwidth and HD video in E1
access mode with ensured QoS. The network access by using 4E1 lines is highly reliable.
When any of the E1 lines is faulty, the HUAWEI VP9035A can detect the fault intelligently
and lower the transmission rate automatically. When the faulty line is recovered, the
HUAWEI VP9035A increases the transmission rate automatically. This entire process is
automatic and fast. Users can hardly be aware of it.
2.7.2 Lossless Digital HD Interfaces
The HUAWEI VP9035A provides high-definition serial digital interface (HD-SDI) and
Digital Visual Interface-Integrated (DVI-I) interfaces through which HD digital video signals

A DVI-I interface is a digital HD signal interface that can be used for displaying the video of
a conference vividly and without any loss. In addition, the video format can be converted into
the High-Definition Multimedia Interface (HDMI) format and an HDMI interface is used to
output the video and audio of the conference. In this case, only one HDMI cable is used for
connecting the HUAWEI VP9035A and the HD television. Thus, the conversion between
digital signals and analog signals is avoided; the signal loss is reduced; the quality and
definition of the video are increased.
The DVI interfaces of the HUAWEI VP9035A comply with the DVI-I technical specifications
with the best compatibility. The HUAWEI VP9035A can output digital signals and analog
signals simultaneously. Thus, lossless conversions can be implemented, including from DVI
to HDMI, from DVI to color difference, and from DVI to VGA. The DVI-I interfaces can be
used along with the input and output interfaces of various mainstream external devices, thus
meeting the requirements of connecting to devices, such as a PC, projector, or RGB matrix.
2.7.3 Convenient PPPoE Dial-Up Function
The HUAWEI VP9035A provides a built-in Point-to-Point Protocol over Ethernet (PPPoE)
dial-up system that supports commonly used broadband network access modes. The users of
the asymmetric digital subscriber line (ADSL), very high bitrate DSL (VDSL), and LAN can
start using relevant services by dialing a number. The users of the LAN refer to the users of
China Telecom or China Netcom that use a LAN for network access. These users should enter
user names and the corresponding passwords before accessing the network.
2.7.4 SIP Line Access
The HUAWEI VP9035A supports the Session Initiation Protocol (SIP). Without software
upgrade, the HUAWEI VP9035A supports both H.323 and SIP, providing good extendibility.

2.10 Strong Adaptability
2.10.1 Adaptability to Physical Environment
The HUAWEI VP9035A is designed and has passed stringent tests in terms of environment
adaptability, security, electromagnetic compatibility (EMC), and reliability. Thus, it has a
proper capability to adapt to harsh environments. By using the intelligent heat protection
function, the inner temperature can be adjusted automatically, thus ensuring the proper
running of the HUAWEI VP9035A even in a hot environment without air-conditioning.
2.10.2 Super Error Concealment
On an IP network, packet loss may occur during data transmission. In this case, the quality of
a conference gets affected.
By using the proprietary super error concealment (SEC) function, Huawei video terminal
series can automatically adjust the quality of service (QoS) and use proper audio-visual
processing policy based on the transmission on an IP network, thus optimizing the audio and

2.10.3 Intelligent Rate Control
The HUAWEI VP9035A supports the E1 intelligent rate control (IRC) technology. During a
conference, multiple E1 lines are used. If one E1 line is disconnected and if there is no backup
line, the HUAWEI VP9035A automatically enables the function of reducing the transmission
rate, thus ensuring the video quality. By using a powerful line detection mechanism, after the
recovery of the faulty line is detected, the HUAWEI VP9035A intelligently restores the line
bandwidth.
In addition, the HUAWEI VP9035A supports the function of reducing the transmission rate on
an IP network. In other words, when the packet loss on a network reaches a serious level, the
transmission rate of streams is reduced to a proper range by using certain technologies and
policies, thus adapting to actual network conditions. When network conditions get better, the
transmission rate is increased automatically and the actual network bandwidth is recovered.
Thus, network resources are used to the maximum to achieve the best audio-visual quality.
2.10.4 Complete Firewall and NAT Traversal Function
The HUAWEI VP9035A provides the static network address translation (NAT) function. In
the case of a few of terminals within a firewall, they can traverse the firewall or a NAT device
by configuring one-to-one mapping relations for public and private networks on the firewall.
In this case, each terminal needs to be allocated with a public-network address.
By working along with the central-office-end devices provided by Huawei, such as a
gatekeeper (GK) and an MCU, terminals can traverse the firewall or the NAT device without
any assistance of an external device or public network addresses. The traversal is
implemented through the Super Network Passport (SNP) that is a proprietary technology of
Huawei. Thus, service intercommunications between private and public network are
implemented. Huawei is the first corporation that implements the firewall and NAT traversal
in the industry.
