Filter



Figure 4-2 ZXV10 M9000 Rear View

The frame is divided into three areas: switching module area (slots 7 to 8), main

control module area (slots 9 to 10), and functional board area (slots 1 to 6, and 11 to

14).

Physically, the main control board and the switching board are in the 1+1 backup

mode. They are installed in fixed slots.

The boards in the functional board area can be inserted in a mixed manner.

Boards can be inserted in the front of and on the back of each slot. The front boards

are functional boards. Generally, the rear boards are the electrical connector

adaptation board, bus extension board, bus terminating resistor board, and clock

board. The system is made into an enclosed chassis, which is helpful to the system's

electromagnetic compatibility (EMC).

4.2 Hardware Architecture

The ZXV10 M9000 system hardware is designed on the basis of the USS platform.

Functional boards of the system use a universal hardware structure to maximize

hardware reuse. Figure 3 is the hardware-function schematic diagram of this

product.

Power module

Fan module

Rear boards



All functional boards except the ECU board reuse the same hardware board, the

GPU board. These boards fall into three types — NCU, ANCU, and VCU, which

implement different media processing functions — according to software modules on

them. Double planes and IP switching are adopted inside the frame. The two planes

refer to the BASE plane and the FABRIC plane. Control signaling is transferred on

the BASE plane; media is transferred on the FABRIC plane. The separation between

control signaling and media prevents media data from blocking control signaling.

In an 4E1 (H.320) system, after receiving code streams from 4E1 lines and

separating singling from media, the 4E1 processing module directly processes part

of the signaling (H320-related signaling), and submits related information to the AS

through the BASE plane for further processing. After being de-multiplexed, the

media data are transmitted to other media processing modules of the system to be



further processed through the FABRIC plane. The 4E1 processing module

multiplexes signaling received from the BASE plane and media data received from

the FABRIC plane, and sends them out of the system through 4E1 lines.

4.2.4 Working Principle of IP (H.323 and SIP) System

The following figure shows the working principle of the ZXV10 M9000 applied on an

IP network.

IP

processing

module

In an IP system (H.323, SIP) system, the processing method for media such as

voices, images, and data is similar to that of 4E1 (H.320) system except that the IP

system adopts a network interface and separately processes signaling and media.

That is, signaling is processed by the protocol stack (H.323/SIP), and media are

received and sent by the IP processing module.

Either in the 4E1 or IP system, the interfaces of the media processing parts are

unified for complete compatibility between the systems. Media processing supports

the functions of matching and conversion of the voices and video among systems on

the basis of different media encoding/decoding formats.



4.2.5 Componential Units

According to different roles and functions, ZXV10 M9000 contains the following 8

constituent units. Each unit is composed of different boards, which jointly perform

various system functions.

MS90 server: runs on the MMU2/MSTU2 or IBM/DELL PC Server, to realize the

service functions of videoconferencing.

Protocol stack: The IP protocol stack runs on the MPCU2; the H.320 protocol

stack runs on the ECU board. The protocol stacks give access to the

videoconferencing terminal signaling and transfers conference control

messages.

VMP media resource management module: runs on the MPCU2 to calculate

and distribute media resources required by media service processing.

Audio processing unit: runs on the ANCU2 or AECU board, and implements

audio encoding/decoding and sound mixing.

The above four units are mandatory for ZXV10 M9000.

IP processing unit: runs on the ANCU2. This unit performs media access for IP

terminals; outputs media monitoring code streams; and gives access to and

outputs media code streams of recorded and on-demand conferences.

4E1 processing unit: runs on ECU. This unit performs 4E1 terminal access,

processes a part of the H.320 protocol, and separates and combines signaling

and media data.

The above two units are access units, which are selected and configured

according to different networking environments. In the case of 4E1 networking,

the 4E1 processing unit is mandatory. In the case of IP networking, the IP

processing unit is mandatory.

Video processing unit: runs on the VCU2. It implements the functions of video

encoding/decoding and continuous presence composition. In cases of

multi-capability conferencing, continuous presence conferencing, IVVR, and



video recording and broadcast, the video processing unit is mandatory.

4.2.6 Software Architecture

ZXV10 M9000 system software is divided to two layers: the service layer and the

media layer. The following figure shows its software architecture.

The functions of each layer are as follows:

The MS90 mainly consists of the Web (user operation interface), service

processing module AS, IP protocol stack, Multipoint Control (MC) module. This

layer implements organization and management and signaling access of

multipoint videoconferences and multipoint conference control.

The media layer consists of resource management module (VMP), IP

processing module (NPU), 4E1 processing module (EPU), audio processing

module (APU), video processing module (VPU). This layer implements media

processing of multipoint videoconferences. The VMP calculates, manages, and

allocates video processing resources needed by multipoint videoconferences,

and coordinates functions performed by media processing modules. The NPU

is responsible for media access of IP terminals, outputs of media monitoring

code streams, conference recording, and access of on-demand streaming. The

EPU is responsible for 4E1 terminal access. The APU is responsible for audio

processing in the system including audio codec and sound mixing. The VPU is

responsible for video processing including video codec, continuous presence

composition, and video superimposition.



The system software adopts the design of separation between the service layer and

media layer, which facilitates system expanding through network connections.

Generally the FEC indices are related to the packet size and the number of

redundant packets. To give consideration to both packet-loss resistance and

real-timeness, generally the higher the bit rate, the larger the packet size, the greater

number of redundant packets, the more NPU capacity occupied. The following table

shows FEC indices.

5.2.7 Multilevel Cascading Indices

Multilevel conference cascading refers to three levels, four levels or even more

levels of cascading on the basis of MCU master/slave conferencing.

Apart from all the functions of master/slave cascading, the multilevel cascading



provides the following new function:

Terminal voice status indication function: The voice status of conference sites

stored by MCU is transferred to terminals, so that the terminals know the voice

status of the conference sites, which can only be seen by the chairman

terminal.

5.2.8 Web/Plug-in Unit Indices

The system supports simultaneous conference control by a maximum of 10

conference control clients. The system provides functions including system

management, conference management, video wall, and Web monitoring on

Web (Web monitoring of V1.1.1 version is implemented by the conference

control plug-in). The conference control plug-in implements the conference

control function. The cross-MCU conference control in cascaded conferencing

has following features:

The terminal list of the whole conference can be viewed in conference control

interface of the upper-level MCU.

The conference control interface of the upper-level MCU is able to display the

terminal list, microphone, sound box, and the status of the local terminal

microphone of a conference on the lower-level MCU.

The conference interface of upper-level MCU supports conference control

functions on the lower-level MCU, such as video broadcast, broadcast source

selection, microphone switching on/off, speaker switching on/off, terminal

disconnection, and terminal deletion.

5.2.9 Power Indices

The requirements for the operating power of the ZXV10 M9000 are as follows:

AC input: 90–264 V, 50/60Hz

DC input: -40 V to -57 V

Power consumption < 2800 W



5.2.10 Working Environment

Generally, a videoconference has certain requirements for the environment of a

conference room, such as the size, temperature, humidity, environment noise and

lighting of the conference room. This, on one hand, ensures that the equipment

works normally and stably. But more importantly, this helps produce an ideal

conference effect. Therefore, generally speaking, a conference room should be well

decorated, where high-quality TV sets are used to display images and such auxiliary

devices as a mixer console and power amplifier are used to improve sound effects.

An equipment room environment suitable for the equipment operation is a

prerequisite for the ZXV10 M9000 equipment installation.

Temperature and humidity in the equipment room

To ensure that ZXV10 M9000 works normally at any time, the equipment room

must be kept in the required temperature and humidity. Too high or too low

temperature/humidity may have a bad influence on the videoconference quality

and the service life of the equipment.

First, too high or too low temperature may considerably reduce the equipment

reliability; long-term operation in a high-temperature environment quickens the

aging of insulation materials, thus shortening the service life of the equipment.

Second, too much humidity is likely to cause various metal parts of the

equipment to become rusty, make some insulation materials to deteriorate in

their performance, and even cause electric leakage. By contrast, a dry

environment with too low humidity is likely to produce static electricity, thus

harming equipment circuits.

In normal cases, the requirements for the temperature/humidity of the

equipment room are as follows.

Table 5-8 Temperature/Humidity Requirements of the Equipment Room

Item Temperature Range Humidity Range

Normal operation 0°C to 40°C 0%–90%



Cleanness of the equipment room

The dust on the equipment may lead to electrostatic adherence and poor

contact of the metal connectors, which affects the equipment lifespan and tend

to cause faults.

The ZXV10 M9000 in normal operation requires that the dust grains in the

equipment room should not be too dense and be non-conductive, non-magnetic

and non-corrosive. The dustproof requirements of equipment room are as

follows:

Table 5-9 Dustproof Requirements of Equipment Room

Item Floating (mg/m3) Sedimentation (mg/m3)

Dust < 0.2 < 35

Anti-static requirements for the equipment room

Static electricity not only affects the normal operation of equipment, but also

shortens the service life of equipment, and even causes accidents. Anti-static

requirements for the equipment room are as follows:

The absolute value of the electrostatic voltage to ground of equipment, walls

and human bodies in the equipment room should be less than 200 V.

The raised floor or antistatic ceramic tiles should be laid in the equipment room,

whose electrostatic protection ground resistance is less than 10 ohm.

In addition, some consideration should be given to electrostatic protection

requirements during equipment unpacking, shipment and operation. An

anti-static wrist strap must be worn before any operation on the equipment.

Fire control requirements for the equipment room:

You must not store any inflammable, explosive or dangerous materials in the

equipment room. Equip the equipment room with effective smoke sensors and

fire control devices.

Power supply requirements



To prolong the service life of the equipment, an Uninterruptible Power Supply

(UPS) must be configured. The UPS ensures power supply reliability of the

videoconferencing system, and reduces electrical interference caused by power

supply. It is recommended that you adopt two independent power supply

systems.

Requirements for security protection:

Lightning protection

Reliable lightning protection measures should be taken in the equipment room.

The grounding wire of the lightening arrester and those of equipment and

the power supply should be designed according to the principle of joint

grounding. Before the yearly thunderstorm season comes, the

maintenance personnel should carefully check whether the lightning

arresters are in sound conditions.

Grounding

Grounding is very important in a power system. If the grounding quality is bad or

if equipment shares the same AC power supply with the lighting system,

the quality of the videoconference signals is likely to deteriorate due to

spurious-wave interference on the power cables (such as noise in audio

outputs and corrugation and jitter in video outputs), and the service life of

equipment is shortened due to a lack of grounding cable protection.

It is advisable to lead grounding wires from the grounding strip in the equipment

room. If a separate grounding electrode is designed for equipment,

grounding resistance of the grounding electrode should be less than 4 ohm.

If it is difficult to provide a separate grounding electrode, the grounding

system of the equipment can share the grounding electrode with other

grounding systems, and the grounding resistance should be smaller than

0.5 ohm. Please note that in the case of joint grounding, the protective

grounding wire must use the fifth wire of the three-phase five-wire system,

and it must be strictly separated from the zero line of the AC power system

lest the power with an unbalanced zero line should severely interfere with

images.



6 Networking

6.1 Networking Units

The ZXV10 M9000 has flexible networking modes. In an H.320 system, the MCU

can be networked with 4E1 terminals through a digital transmission network. On an

IP network, the MCU can be connected to terminals of H.323 and SIP protocol at the

same time. Moreover, the ZXV10 M9000 can be applied in hybrid networking of 4E1

and IP, and constitute a videoconferencing system together with different types of

conference terminals.

The ZXV10 M9000 has a powerful networking capability. During actual application,

the ZXV10 M9000 is able to cope with various complex conference environments. If

a conference network contains H.320 terminals, H.323 terminals and SIP terminals

at the same time, the built-in gateway function of the ZXV10 M9000 enables hybrid

networking of them all. If conference terminals use different rates, or if they are

configured with different audio/video capabilities, the matching function of the ZXV10

M9000, which is not limited to matching of different rates, enables these terminals to

coexist in the same conference. As a matter of fact, the ZXV10 M9000 has

transcended limits of traditional MCUs, and become a new-generation intelligent

video server that meets the requirements of any terminal, any network and any

conference.

6.2 Networking Applications

6.2.1 Networking Through IP

The GK, SIP Server, MCU and terminals are connected through the TCP/IP channel.

The access mode of TCP/IP-based H.323/SIP terminal can be ADSL dial-up access

or LAN access, which may be DHCP dynamic IP address distribution.

As shown by the above figure, the ZXV10 M9000 supports E1 networking of an

H.320 system as well as cascaded networking through an 4E1 network.

The ZXV10 M9000 is connected with 4E1 terminals in three ways:

Connected directly with a coaxial cable when the cabling distance between the

terminal and the MCU is smaller than 300m

Connected through a digital line transmission network when the cabling

distance between the terminals and the MCU is greater than 300m, and an 4E1

interface exists between them

HDSL transmission equipment can be selected for distance lengthening

(effective transmission distance: 5 km), when the cabling distance between the

terminals and the MCU is greater than 300m, but no 4E1 interface exists



between them.
