Field

Description

Enable Fixed Ports

Enable Fixed Ports

Select this check box to enable the configuration of

 

firewall ports used for signaling, control and media. If

 

you are defining a service for local calls that do not

 

require configuring the firewall to accept calls from

 

external entities, leave this check box clear.

 

 

Number of calls

Enter the Number of Calls based on the predicted

 

number of simultaneous incoming calls that require

 

fixed port allocation and are handled by the network

 

and MCU, up to the maximum that can be handled

 

by the IP card (dependent on card type).

 

If you exceed the maximum number of calls

 

configured for the card an error message appears

 

listing the call range that can be entered.

 

 

Port Range

The following general instructions apply to the

Definitions

Signaling, Control, Audio, Video, data and FECC

 

fields.

 

Define the port ranges for each of the channels;

 

enter the first port for each channel and the system

 

automatically fills in the end of the assigned port

 

range. The IANA recommended port range is 49152

 

to 65535.

 

The network administrator configures the server and

 

allocates firewall ports based the number of ports

 

required for each media channel (13 in total) and the

 

volume of incoming traffic via the firewall (the

 

number of simultaneous calls).

 

For example: If each call is allocated 13 ports

 

(Signaling - 1, Control - 1, Audio - 2, Video - 4, and

 

Data - 5, for a total of 13 ports), and 6 simultaneous

 

calls are to be handled by the network, the total

 

number of ports that is required is 78 (6 x 13). If the

 

first allocated port is 1025, then the last port will be

 

2003 (1025 + 78 = 2003).

MGC-50, MGC-100 specifications

The Polycom MGC (Multipoint Gateway Controller) series includes notable models such as MGC-100 and MGC-50, designed to enhance video and audio conferencing capabilities in various organizational setups. These systems are pivotal for facilitating effective communication in a world where remote collaboration is increasingly essential.

The Polycom MGC-100 serves as a powerful multipoint control unit (MCU), allowing multiple concurrent video and audio sessions. It is particularly suitable for larger enterprises and organizations that require sophisticated conferencing capabilities. 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.
