Service Mode

Board Hunting – In this mode, the MCU is

 

(cont.)

registered with the gatekeeper using the Network

 

 

Service prefix. In addition, all the IP cards that

 

 

are defined in the same Network Service register

 

 

with the gatekeeper with the same prefix.

 

 

When using the Network Service Prefix for

 

 

dialing, the IP call that reaches the gatekeeper is

 

 

forwarded to first available IP card on the MCU

 

 

according to the cards registered with the

 

 

gatekeeper for the Network Service whose prefix

 

 

was used. In this mode, the dialed string must

 

 

begin with the IP Service prefix and can be

 

 

followed by the conference Numeric ID. For

 

 

example: [H.323 prefix] [Conference/Meeting

 

 

Room numeric ID/name].

 

 

In a gateway call, the prefix can be followed by a

 

 

Gateway Session Profile or by another format

 

 

that can be read by the gateway:

 

 

[H.323 prefix] [gateway service prefix] [gateway

 

 

delimiter] [gateway information]

 

 

Notes:

 

 

This mode is dependent on the gatekeeper’s

 

 

implementation as the gatekeeper may not

 

 

allow multiple registrations from different IP

 

 

addresses.

 

 

Board Hunting is the default mode. It is not

 

 

recommended to use Board Hunting with

 

 

Forwarding. If both are selected, Forwarding

 

 

overrides Board Hunting settings.

 

 

Register as a Gateway – Select this mode when

 

 

using a Cisco gatekeeper.

 

 

In this mode the gatekeeper is defined as a

 

 

gateway. A gateway prefix is usually manually

 

 

registered with the gatekeeper and the IP cards

 

 

use the same prefix to register with the gateway.

 

 

With a Cisco gatekeeper that supports this

 

 

mode, the MCU is registered as an

 

 

H.320-gateway and it requires the dialing string

 

 

to start with the prefix as with Board Hunting.

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.
