Alarm Output Connection

Chapter

Dry contact relay closures are available for forwarding MGX 8220 alarms to a user office alarm system. Separate visual and audible alarm outputs are available for both major and minor alarm outputs. The MGX 8220 alarm outputs are available from a DB15 connector on the BNM line module faceplate. See Appendix B, “Specifications,” for the pinouts on this connector. Use switchboard cable for running these connections.

Making External Clock Connections

If the MGX 8220 node is to be synchronized to some other external equipment or a local digital central office, a connector on the back card can be used to provide a clock input.

For a T1 clock input, the DB15 connector marked EXT TMG on the T3E3-D or SMF-155 line module is used.

For a E1 clock input, the BNC connector marked EXT TMG on the T3E3-B or SMF-155 line module is used.

Attaching a Control Console

The control console can be attached to either the maintenance port or to the control port.

Dumb Terminal onto the Maintenance Port

When using an alphanumeric (dumb) terminal to input command-line interface commands, the terminal must be connected directly (no modem) to the maintenance port DB25 connector on the ASC line module faceplate. Use a conventional RS-232 cable with a DB25 connector at each end. A so-called “Null Modem” cable is not required. This port should never be Y-cabled.

Workstation onto the Control Port

When using a workstation to issue commands or transfer files to and from the shelf, the workstation can be attached through the RS-232 control port on the ASC line module faceplate. Using this connection requires the workstation to communicate using TCP/IP and SLIP communication protocols.

The workstation can be attached either directly with no modems or remotely through modems. In either case, a conventional RS-232 modem cable should be used.

If the shelf has dual redundant ASC modules, use a Y-cable to connect the workstation or modem to the control port of both the ASC modules. If a modem is used, a null-modem cable is required.

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.
