Description

Gatekeeper

Use Gatekeeper

Off – select this option if a gatekeeper is not

 

present in your network. In this case, the MCU

 

uses the IP addresses for dial out and the

 

endpoints use the IP addresses of the MCU IP

 

cards for dial-in.

 

Specify – to manually define the IP address of

 

the preferred and alternate gatekeepers.

 

Auto – to retrieve the IP address of the preferred

 

and alternate gatekeepers from the DHCP, if they

 

are defined in the DHCP and the DHCP option is

 

enabled.

 

 

Preferred

If you have selected Specify, enter either the

Gatekeeper IP

gatekeeper’s host name (if the DNS server is

Address or Name

enabled and the gatekeeper is registered with the

 

DNS), or IP address.

 

 

Alternate

If you have selected Specify, enter the host name or

Gatekeeper IP

IP address of the alternate gatekeeper.

Address or Name

 

 

 

Port

Displays the port number (1719) used for

 

communication between the MCU and the

 

gatekeeper.

 

 

Service Mode

Select the mode in which the gatekeeper routes calls

 

from a card without free ports to the card with

 

available resources. If there is no gatekeeper, calls

 

that reach an IP card with unavailable resources is

 

rejected, unless Forwarding is enabled.

 

Basic [Least recommended] – Each IP card in

 

the MCU registers independently with the

 

gatekeeper. The H.323 endpoint dials directly to

 

this card, using the cards alias as registered with

 

the gatekeeper. The call is routed once to the

 

MCU card. If the card has resources, the call is

 

accepted, otherwise the call is rejected.

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.
