NOTE
The TX50, with H.265 4K x 2K enabled, cannot initiate SiteCalls.
SiteCall is a unique conference function provided by Huawei. It allows users to define
conferences and participants on the endpoint, making it simple to initiate a multi-party
conference. Users can create conferences using the touch panel, web interface, or remote
control of the endpoint. After setting conference parameters (such as the conference name,
data rate, and number of sites), the users can start the conference. The endpoint can initiate
conferences through H.323 or SIP.
5.5 P2P to Multipoint
NOTE
If the H.265 4K x 2K video capability is enabled for the TX50, the function of switching a P2P call to a
multipoint call will be unavailable.
When the endpoint is connected to an MCU, you can turn a P2P call into a multipoint call,
increasing conference efficiency. Below are different scenarios where this may be necessary.
Local Site Receiving Calls from Other Sites
If two sites are having a P2P call and one of the sites receives another incoming call (or
multiple incoming calls), that site can perform one of the following operations:
l
Answer&Merge: Answer calls from other sites and turn the P2P call into a multipoint
conference.
l
Answer&Hold: Answer calls from other sites and place the original P2P call on hold.
Then you can place calls on hold or merge calls as follows:
–
Call Hold: The site in an active call can be placed on hold or released, and the site
on hold can be resumed off hold or released. In call hold state, the local and remote
sites cannot hear or video each other. They can do this only after the call hold
operation is canceled.
–
Merge: Place the original P2P call on hold, and set up a call with another site or to
several other sites, and turn the P2P call into a multipoint conference.
l
Answer&Release: Answer calls from other sites and release the original P2P call.
l
Ignore: Ignore calls from other sites, close the incoming call notification dialog box, and
continue the original P2P call.
l
Reject: Reject calls from other sites and continue the original P2P call.
Local Site Placing Calls to Other Sites

5 Functions and Features
Local conference
The RSE server's IP address is set on the endpoint, and neither the endpoint or the RSE
server needs to be registered with a GK server.
l
Multipoint conference hosted by SMC2.0
An SMC2.0 uniformly allocates RSE resources. The SMC2.0 sends RSE site
information to the MCU, and the MCU adds the specified RSE to the conference to
enable recording. Operations such as starting conference recording and configuring the
RSE server can be performed on the SMC2.0. The SMC2.0 also supports automatic
conference recording and automatic activation of the conference recording function.
l
Multipoint conference directly initiated from the endpoint
The endpoint and RSE server need to be registered with a GK server. The URL or IP
address of the RSE server needs to be configured on the endpoint. During a multipoint
conference, only the chair site can perform recording operations.
5.12 Wi-Fi Connectivity
The endpoint has a built-in Wi-Fi module and is able to function as a Wi-Fi client, a Wi-Fi
server, or both simultaneously. The maximum bandwidth is 54 Mbit/s and the frequency is 2.4
GHz.
If the endpoint has the Wi-Fi client function enabled, it automatically detects and connects to
Wi-Fi servers. You can set the endpoint IP address in DHCP or static mode. If a wired
network deployment is not suitable, the endpoint can connect to the Internet through a
wireless router. Therefore, the Wi-Fi client can be enabled when wired networks are
unavailable and the endpoint needs to access networks through wireless routers.
If the endpoint has the Wi-Fi server function enabled, it can connect to two VPM220Ws
(Huawei's wireless microphone array) through Wi-Fi, eliminating the need for physical
connections.
If a user also purchases a wireless microphone or touch panel, the user can connect it to an
endpoint through Wi-Fi to control the product.
Figure 5-7 shows the Wi-Fi network.

Product Overview
5 Functions and Features
5.18 Adaptation of and Conversion Between the 16:9 and
4:3 Display Modes
The endpoint can automatically detect monitors connected to it. The image ratio on the
monitors varies with the video protocol and definition settings. If the local site needs to
display the 4:3 video from a remote site on a monitor with a 16:9 LCD, the endpoint simply
adjusts the video to prevent distortion.
5.19 VGA Bypass
A DVI-I port is required to enable VGA input and output for the TX50. When the endpoint is
powered off, VGA images can be input from the DVI-I port and output from the DVI-I port
through endpoint bypass. That means the image input and output is on the single VGA cable.
There are several scenarios during a conference:
l
Connect the VGA output port of a PC to the VGA input port of a projector.
l
Connect the VGA output port of a PC to the DVI-I port of the endpoint.
If your PC is connected to the endpoint (projector) but the (projector) endpoint is faulty, you
have to unplug the VGA cable connected to the PC from the endpoint (projector) and connect
the PC to the projector (endpoint) using the VGA cable. To address this trouble, the endpoint
provides the VGA loopback function. To use this function, connect the VGA output port on
the PC to the DVI-I input port on the endpoint and connect the DVI-I output port on the
endpoint to the VGA input port on the projector. If the endpoint is faulty, it will function as an
intermediary between the PC and the projector. You do not need to cope with the fault by
plugging and unplugging cables.
5.20 Microphone Array Cascading
The VPM220, Huawei's homegrown wired microphone array, can connect to the endpoint and
function as a sound pickup device. When the conference room is large and conference
participants are scattered, two VPM220s can be cascaded to deliver optimal audio effects. The
maximum distance between two cascaded VPM220s is 12 meters, and the suggested distance
is 3 to 6 meters.
5.21 Seamless Convergence with IMS and USM
The endpoint can connect to the IMS hosted network (core component: IMS) or the SP hosted
network (core component: USM) through the SIP protocol and then initiate or join HD video
conferences to communicate with other clients and terminals.

TX50 Videoconferencing Endpoint
Product Overview
5 Functions and Features
Network Layer Security
The on-premises, IMS hosted, and SP hosted networks have implemented different network
layer security policies.
l
l
On-premises network:
–
The endpoint, SMC2.0, and MCU are deployed in the trusted zone, isolated from
the Demilitarized Zone (DMZ) and the untrusted zone. Firewalls are deployed for
security domain division and access control.
–
Terminals (such as TE Desktop and TE Mobile) in the untrusted zone communicate
with NEs in the trusted zone through the Session Border Controller (SBC) or
Switch Center (SC) in the DMZ.
IMS hosted and SP hosted networks:
–
The endpoint is deployed in the untrusted zone, isolated from the DMZ and the
trusted zone through the SBC or the extranet firewall.
–
If the DMZ is deployed, install the SBC, SC, USM Proxy, and MediaX Proxy in the
DMZ for endpoint connections.
–
If no DMZ is deployed, the endpoint connects to the trusted zone through the SBC.
The USM Proxy and MediaX Proxy are not required.
–
On network borders between the DMZ and the trusted and untrusted zones,
firewalls are deployed to implement security domain division and access control.
Firewall Technology (NAT)
The firewall protects your IP network by separating the internal and external network
communication data. Using Network Address Translation (NAT) technology and exchanging
signaling between public network protocols and private network protocols, the firewall
enables sites on local area networks (LANs) in different places to enjoy the convenience of
communication through video conferences. With NAT, a device on an LAN is allocated a
dedicated internal IP address that uniquely identifies the device on the LAN, and the device
uses an external IP address to communicate with external devices. Through NAT mapping,
multiple internal IP addresses are mapped to one external IP address. NAT mapping not only
reduces the number of IP addresses that are needed for users on a private network to access
the Internet, but also enhances the security of the private network.
Secure Public-Private Network Traversal
The standard H.460, SIP Interactive Connectivity Establishment (ICE), and exclusive Super
Network Passport (SNP) firewall traversal technologies are used to set up secure connections
between the public and private networks or between different private networks through
firewalls.
Network Diagnostics
To ensure superb audio and video, you can use the diagnostic tool released with the endpoint
software version to check the network performance, including:
l
