Chapter

Setting up a Frame Relay Connection

For line number, specify the FRSM line used to connect to the Frame Relay equipment (1 to 4, with 1 being the top line).

For DS0 speed, specify either 1 for 56 kbps or 2 for 64 kbps.

For the beginning timeslot, specify the beginning timeslot in the T1 or E1 line.

For number of timeslot, specify the number of consecutive T1 or E1 timeslots to be used for the connection.

Step 5 Enter the addchan command to enable the Frame Relay channel.

Select network interworking or service interworking in the chan_type parameter. 1 is for network interworking.

For channel number, enter a value between 16 and 271. THIS WILL BE THE SAME NUMBER SPECIFIED IN THE VCI FIELD TO/FROM THE BPX SWITCH.

For port number, enter the port number previously enabled.

For DLCI, enter a DLCI number to be used in communicating with the Frame Relay equipment.

Note Once a service module channel is started in the MGX 8220 shelf, the T3 line to the BPX switch is automatically up, configured, and started by the MGX 8220 shelf and no action is required by the operator.

Note Remember that this process must be repeated at the remote end to establish the segment at that end.

At this point the MGX 8220 shelf segment is up with default parameters.

Establish the BPX-to-BPX Segment

The following steps should be performed to establish the required BPX-to-BPX segments.

1.Enter the addcon command at one of the BPX nodes (not both) as follows.

For slot number and port number, specify slot and port of the BNI port connected to MGX 8220.

For VPI, specify the slot number in the MGX 8220 shelf that contains the FRSM attached to the BPX.

For VCI, specify the logical channel number (LCN) of the Frame Relay connection configured on the local MGX 8220 shelf.

For Nodename, specify the nodename of the BPX at the other end of the connection.

For Remote Channel, specify the BNI slot and port number of the BNI port attached to MGX 8220 at the remote end. Specify the VPI as the slot number of the remote MGX 8220 FRSM connected to the BPX and specify VCI as the LCN of the Frame Relay connection at the remote MGX 8220.

Specify the type of connection. ATFR when ForeSight is not being used and ATFST when

ForeSight is being used.

2.Enter the other addcon parameters of bandwidth, and so on.

MGX 8220 specifications

The Cisco Systems MGX 8220 is a versatile, high-performance media gateway that has become an integral component in the telecommunications infrastructure. Designed to facilitate the transition from traditional circuit-switched networks to advanced packet-switched environments, the MGX 8220 supports a wide array of voice, video, and data services, making it an essential tool for service providers and enterprises seeking to enhance their network capabilities.

One of the key features of the MGX 8220 is its robust signaling and media processing capabilities. Equipped with support for both Voice over IP (VoIP) and traditional telephony protocols, this gateway enables seamless integration of different communication formats. It boasts a modular architecture, which allows for the addition or removal of various line cards to meet changing demands and technology advancements. This modularity provides operators with the flexibility to scale their services without significant overhauls to their existing infrastructure.

The MGX 8220 is capable of delivering high-density media handling for a multitude of services. With its support for ATM and IP networks, the gateway can handle TDM (Time-Division Multiplexing) to packet voice conversions efficiently. It is designed to optimize network resources by dynamically allocating bandwidth based on traffic requirements, thus ensuring efficient use of network resources and improved performance.

Another significant characteristic of the MGX 8220 is its enhanced quality of service (QoS) features. This capability ensures that voice and video traffic is prioritized appropriately, minimizing latency and jitter while maximizing overall call quality. By employing sophisticated traffic management techniques, the MGX 8220 can deliver a superior user experience, which is critical for any service provider aiming to offer competitive communication solutions.

Furthermore, the gateway includes built-in security features to protect against unauthorized access and ensure the integrity of sensitive data. This includes encryption for voice and video transmission, as well as support for secure signaling protocols.

Overall, the Cisco Systems MGX 8220 stands out as a comprehensive media gateway solution, providing essential functionalities for modern communication needs. Its combination of modularity, high-density processing, effective QoS management, and security features makes it a compelling choice for organizations looking to modernize their telecommunications infrastructure while ensuring reliability and performance. As businesses continue to evolve and demand more from their networks, the MGX 8220 offers a pathway to future-ready communications.
