Configuring Service on a T3 or E3 CESM

Error and Alarm Response

When it detects a loss of signal (LOS) alarm, the CESM notifies the connected CPE in the upstream direction after an integration period. The CESM continues to emit cells at the nominal rate but sets the ATM cell payload with an appropriate data pattern as specified by the ATM Forum CES V2.0 specification. Also, an OAM cell with RDI code goes to the far end to indicate out-of-service. The significance of the different types of alarms appears in Table 6-3.

Configuring Service on a T3 or E3 CESM

This section first describes the steps for configuring the card, line, and port-level parameters for an MGX-CESM-T3 and MGX-CESM-E. It then describes how to add a connection. If necessary, refer to the section titled “Tasks for Configuring Cards and Services” for background information on these types of tasks. Use either the CLI or the CiscoView application to set up the card and line parameters. Use either the CLI or the Cisco WAN Manager application to add connections. The fundamental tasks and applicable CLI commands appear in the following list. For a complete list of CLI commands that apply to the CESM cards, use the Help command on the CLI of the card or refer to the tables at the front of the Cisco MGX 8850 Wide Area Edge Switch Command Reference.

•Optionally configure Y-cable redundancy at the card level (addred on the CLI).

•Optionally modify resource partitioning at the card level (cnfcdrscprtn)

•Activate a physical line (addln on the CLI) and optionally configure the line (cnfln) for line coding, line length, and clock source.

•Activate the functioning of the logical port on a physical line (addport)

•Optionally modify resource partitioning at the port level (cnfportrscprtn)

•Add the connections by using addcon (or addchan if NSAP addressing is necessary)

•Configure the connection for CDVT, cell loss integration period, and egress buffer size by using cnfcon (or cnfchan if NSAP addressing is necessary).

Cisco Systems is a leader in networking technology and infrastructure, providing solutions that drive innovation and efficiency for businesses worldwide. Among its diverse range of products, the MGX series stands out as a pivotal component for the network-centric era, especially with models like MGX-FRSM-2CT3, MGX-FRSM-2T3E3, and MGX-FRSM-HS2. These modules are primarily designed for the MGX 8800 series routers, facilitating efficient traffic management and service delivery.

The MGX-FRSM-2CT3 is a versatile module that supports two T3 connections. It allows network operators to seamlessly integrate high-capacity circuit-switched and packet-switched data on a unified platform. This versatility is crucial for service providers looking to enhance their bandwidth offerings while ensuring reliable performance across voice, video, and data applications.

In contrast, the MGX-FRSM-2T3E3 module caters to operators needing E3 support. This feature allows for efficient data transport over a broader bandwidth, catering to European standards. The E3 configuration is vital for service providers operating in Europe or regions that utilize E3 technology prominently.

The MGX-FRSM-HS2 module is another significant offering, designed to accommodate the increasing demand for high speed and high capacity. It supports higher-order TDM and packet technologies, enabling operators to implement advanced services such as VoIP, video conferencing, and other data-intensive applications. This module provides scalability and reliability, making it ideal for next-generation networks.

All three modules leverage Cisco’s advanced switching and routing technology, ensuring optimal performance and minimal latency. The integration of Quality of Service (QoS) features allows network administrators to prioritize traffic types effectively, ensuring mission-critical applications receive the necessary bandwidth.

Additionally, these MGX modules support various signaling protocols, enabling interoperability with existing network infrastructure while also facilitating the migration to newer technologies. They play an essential role in modernizing telecom networks, allowing service providers to adapt to changing market demands and technology landscapes.

In summary, the Cisco MGX-FRSM-2CT3, MGX-FRSM-2T3E3, and MGX-FRSM-HS2 modules are key components for businesses looking to enhance their networking capabilities. With their robust support for T3 and E3 technologies, high scalability, and advanced QoS features, these modules empower service providers to deliver a wide range of services, drive innovation, and meet the growing demands of users in an increasingly connected world.
