Field

Description

 

 

Service mode

Note: In current Cisco implementations when

(cont.)

there is more than one IP card in use, the

 

gatekeeper selects one of the boards that are

 

registered with the dialed string. Thus the system

 

does not automatically forward the calls to an

 

available card. To overcome this problem,

 

combine Register as a Gateway with

 

Forwarding. However, this method only works for

 

defined dial-in participants.

 

• PseudoGatekeeper – Each IP card acts and is

 

defined as a gatekeeper allowing Board Hunting

 

to be performed. In PseudoGatekeeper mode,

 

the IP cards are manually registered with the

 

gatekeeper as neighboring gatekeepers. When

 

the gatekeeper receives an Admission Request

 

(ARQ) message from a participant looking for the

 

conference alias, the gatekeeper will forward the

 

request to all “neighboring gatekeepers” (IP

 

cards) simultaneously. The first card that has

 

enough resources to handle the call accepts the

 

request.

 

Note: Gatekeepers often send a multicast LRQ

 

message hoping that there is a gatekeeper that

 

can help with the translation. Multicast LRQ

 

messages are not handled by the MCU IP cards

 

within the Pseudo Gatekeeper mode.

 

• PseudoGatekeeper-AVF – Applicable to the

 

Avaya environment only.

 

 

Prefix

Enter the same prefix that was defined for the

 

MCU’s IP Network Service in the gatekeeper (if it

 

was defined in advance) or that will be used to

 

register the MCU in the gatekeeper later. This

 

number is used as part of the dial-in string given to

 

participants.

 

Usually, one Network Service is defined for all IP

 

cards to let the system automatically manage the

 

resources allocated to conferences. In this case, the

 

system finds the free cards from the pool of cards

 

registered with the IP Network Service.

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.
