Description

 

 

Port Range

In this example port number 1037 has not been

Definitions

allocated, as the starting range for audio and video

(cont.)

port allocation has to be an even number. If an odd

 

number is entered an error message appears to

 

remind you of this requirement.

 

Note: You can allocate the same port number to

 

different channels provided the numbers are in two

 

different protocols; one is in TCP and the other is in

 

UDP. For example you can allocate port numbers

 

2000-2009 to the Signaling channel in TCP and

 

ports 2000 -2002 to the Audio channel in UDP.

 

 

Signaling [TCP]

Define the ports used for transferring call setup

 

messages. After you enter the first port in the range,

 

the system automatically fills in the last port in the

 

range according to the total number of calls.

 

 

Control [TCP]

Define the ports used for control messages (setup,

 

maintenance, and teardown of sessions). After you

 

enter the first port in the range, the system

 

automatically fills in the last port in the range.

 

 

Audio [UDP],

Define the ports used for audio and video channels.

Video [UDP]

After you enter the first port in the range, the system

 

automatically fills in the last port in the range.

 

 

Data [TCP]

Define the ports used for transferring data packets:

 

file transfer, whiteboard, and application sharing.

 

The recommended port range is 49152 to 65535.

 

After you enter the first port in the range, the system

 

automatically fills in the last port in the range

 

according to the total number of calls.

 

 

FECC [UDP]

Define the ports used for FECC. After you enter the

 

first port in the range, the system automatically fills

 

in the last port in the range.

Supporting both standard definition (SD) and high definition (HD) video, the MGC-100 can manage high-quality video streams seamlessly. Its ability to integrate with different conferencing systems and technologies makes it a versatile tool for enterprises looking to enhance their collaboration efforts.

Some standout features of the MGC-100 include its support for a wide range of protocols, including H.323 and SIP, ensuring compatibility with various endpoint devices. This model can accommodate a substantial number of participants, depending on the configuration, with options for scalability. The system also boasts advanced features such as content sharing, enabling users to present slides, documents, and other materials during conferences.

On the other hand, the Polycom MGC-50 is designed for smaller organizations or departmental use. While it provides fewer simultaneous sessions than the MGC-100, it still offers robust features that make it ideal for moderate conferencing needs. The MGC-50 also supports both H.323 and SIP protocols, ensuring smooth interoperability with various video conferencing endpoints. This model features straightforward management capabilities, allowing administrators to set up and control conferences with ease.

Both models are built with advanced video processing technologies, ensuring high-quality audio and video transmission. The inclusion of error correction and packet loss recovery technologies further enhances user experience, minimizing disruptions during calls. The systems also support a variety of codecs, ensuring optimal performance across different network conditions.

In terms of characteristics, both the MGC-100 and MGC-50 emphasize reliability and ease of use. They come with user-friendly interfaces and remote management capabilities, making it simple for IT professionals to maintain and configure the systems. In conclusion, the Polycom MGC series, with its MGC-100 and MGC-50 models, exemplifies a commitment to quality and performance in multipoint conferencing, catering to diverse organizational needs while facilitating effective communication strategies.
