Circuit Emulation Service Module for T3 and E3

•route_priority is the priority of the connection for re-routing. The range is 1–15 and is meaningful only in relation to the priority of other connections.

•max_cost is a number establishing the maximum cost of the connection route. The range is 1–255 and is meaningful only in relation to the cost of other connections.

•restrict_trunk_type is a number that specifies the type of trunk this connection can traverse. The numbers are 1 for no restriction, 2 for terrestrial trunk only, and 3 for satellite trunk only.

•pcr is the peak cell rate in cells per second (cps). For T3, the maximum is 118980 cps. For E3, the maximum is 91405 cps.

•

•

mcr is the minimum cell rate. The range is 1–65535 cells per second.

pct_util is the percent utilization in the range 1–100.

Bit Error Rate Testing on a T3 or E3 CESM

An active MGX-CESM-T3 or MGX-CESM-E3 can perform a bit error rate test (BERT). Each of these cards contains its own BERT controller, so BERT sessions can run on any number of these cards in the system. However, only one user at a time can run BERT on a card. BERT disrupts service because it requires the tested path to be in loopback mode.

The CLI commands (whose functions correspond to CiscoView selections) appear in the following list. The correct order of task execution is crucial for obtaining valid results. With the exception of dspdsx3bert, you must execute the commands in the order they appear in the following list. You can execute dspdsx3bert before, during, or after a session. Because the order of execution is crucial, read the command descriptions whether you use the CiscoView application or the CLI.

•acqdsx3bert determines if another user currently is running a BERT session on the card.

•startdsx3bert starts a BERT test (after resetting BERT counters).

•cnfdsx3bert specifies a pattern for the BERT test.

•moddsx3bert injects multi-rate errors into the BERT bit stream.

•deldsx3bert ends the current test (and retains the values in the BERT counters). This command also resets the status of current users that acqdsx3bert detects.

•dspdsx3bert displays the parameters and results of the current test. You can execute this command at any time.

See the Cisco MGX 8850 Wide Area Edge Switch Command Reference for command details.

Note When a BERT session begins, all the connections on the line go into alarm and return to normal when you end the test. Consequently, the test may result in a large number of traps and other types of traffic (such as AIS).

MGX-FRSM-HS2, MGX-FRSM-2T3E3, MGX-FRSM-2CT3 specifications

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.
