Cisco uBR10-LCP2-MC16C/MC16E/MC16S Overview

The default modulations are:

•64 quatrature amplitude modulations (QAM) for downstream.

•quadrature amplitude phase-shift keying (QPSK) for upstream.

DOCSIS and EuroDOCSIS Data Rates and Modulation Schemes

Cisco cable interface line cards are configured in a number of different upstream combinations based on the card used, your cable network, and the anticipated subscription and service levels. Table 2 lists the data rates and modulation schemes for both DOCSIS and EuroDOCSIS standards.

Cisco uBR10-LCP2-MC16C

The Cisco uBR10-LCP2-MC16C cable interface line card output is +42 dBmV +/– 3 dB and supports all DOCSIS upstream channel widths described in Table 2. The card is configured identically to the Cisco uBR-MC16C cable interface line card.

Note The configuration information for the Cisco uBR10-LCP2-MC16C is the same as the information for the Cisco uBR10-LCP2-MC28C/Cisco uBR-MC28C, except that there are fewer upstream and downstream ports. Refer to the configuration guides.

For Cisco IOS software requirements see the “Obtaining Documentation” section on page 29.

Cisco Systems has long been a leader in providing robust networking solutions, and its line of Modular Converged Broadband Routers (MCBR) reflects this commitment to performance and innovation. Among these offerings is the MC16E, alongside the uBR10-LCP2-MC16S, uBR10-LCP2-MC16E, and uBR10-LCP2-MC16C. These models are designed to meet the diverse demands of modern broadband networks, enabling service providers to efficiently manage data, voice, and video services.

The MC16E serves as a highly scalable platform that is capable of supporting high-density cable applications. Its architecture supports advanced features such as multiview video streaming, high-speed data transfer, and Voice over IP (VoIP) support. With a focus on maximizing bandwidth and ensuring reliable service delivery, the MC16E is optimized for applications requiring significant network resources.

The uBR10-LCP2-MC16S, uBR10-LCP2-MC16E, and uBR10-LCP2-MC16C are integral components of the uBR10 series, designed to enhance the capabilities of the cable provider’s network. These models feature specialized Line Card Platforms (LCP) that provide modular flexibility and computational power. The LCP allows for easy integration and upgrading, ensuring that the network can adapt to future technology advancements and increased demand.

One of the standout features of these devices is their support for DOCSIS 3.1 technology. This enables service providers to deliver high-speed internet services with impressive download and upload speeds, reducing latency and improving overall user experience. In addition, the routers are equipped with advanced Quality of Service (QoS) mechanisms, enabling better prioritization of critical data traffic, which is essential for maintaining service quality, especially in mixed-service environments.

Another characteristic of these routers is their redundancy and reliability features. With options for network backup and failover mechanisms, service providers can ensure uninterrupted service, a critical requirement in today’s always-on digital environment.

The MC16S model is particularly noteworthy due to its dual-mode operation, supporting both IPv4 and IPv6, which is essential as networks transition to newer internet protocols. Cisco's continued innovation ensures that these routers stay relevant in a fast-paced technological landscape.

In summary, Cisco's MC16E, uBR10-LCP2-MC16S, uBR10-LCP2-MC16E, and uBR10-LCP2-MC16C provide a powerful and flexible solution for modern broadband networks. With high scalability, advanced QoS features, and robust support for new protocols, these devices are key to enhancing service delivery for providers looking to stay ahead in the competitive broadband market.
