Octal-Port DMT ATU-C Line Card

Prerequisites

Prerequisites

To use the 8xDMT feature, you must have one of the following DSLAMs with the 8xDMT line card, and IOS 12.1(6) or above installed:

•Cisco 6015

•Cisco 6160

•Cisco 6260

Configuration Tasks

See the following sections for configuration tasks for the 8xDMT feature. Each task in the list indicates if the task is optional or required.

•Preprovisioning the 8xDMT Line Card, page 6 (optional)

•Creating and Associating a DSL Profile with Each Port, page 7 (required)

•Modifying the DSL Profile, page 7 (optional)

Preprovisioning the 8xDMT Line Card

Starting at the global configuration prompt, use the following commands to preprovision a slot for use with the 8xDMT line card:

 

Command

Purpose

Step 1

 

 

DSLAM(config)# slot 1 ATUC-1-DMT8

This command associates the 8xDMT line card with

 

 

the specified slot.

Step 2

 

 

DSLAM(config)# dsl-profile 8xDMT

Creates and names the DSL profile, 8xDMT in

 

 

this example.

Step 3

 

 

DSLAM(config-dsl-prof)# exit

Return to the global configuration prompt.

Step 4

 

 

DSLAM(config)# interface atm1/1

Enter interface configuration mode on the port

 

 

where you will associate the 8xDMT DSL profile.

 

 

Repeat this process on each port that you wish to

 

 

associate with a DSL profile.

Step 5

 

 

DSLAM(config-if)# dsl profile 8xDMT

Associates the DSL profile named 8xDMT with

 

 

atm interface 1/1.

Step 6

 

 

DSLAM(config-if)# exit

Return to the global configuration prompt.

 

 

 

Tips After you have completed these steps, insert the 8xDMT line card to activate the card with your preprovisioned configuration.

Verifying the Preprovisioned Slot

Use the show running-configurationcommand to verify that you preprovisioned the slot correctly.

8xDMT specifications

Cisco Systems’ 8xDMT, or "Eightfold Digital Multicast Technology," is a pioneering solution designed to optimize multicast traffic management and enhance the scalability of network performance. This technology comes into play primarily in video broadcasting, online gaming, and other applications that require the efficient distribution of data to multiple endpoints, significantly reducing the bandwidth use while improving overall network efficiency.

One of the primary features of Cisco 8xDMT is its ability to support multiple multicast streams concurrently. By using advanced algorithms, 8xDMT ensures that network resources are utilized efficiently, minimizing latency and maximizing throughput. This makes it particularly advantageous for service providers and organizations that deliver high-definition video content or require real-time data transmission across geographic locations.

Another notable characteristic of the Cisco 8xDMT is its integrated Quality of Service (QoS) capabilities. This feature allows for the prioritization of multicast traffic, ensuring that critical data packets are transmitted smoothly without delay, even during peak load times. The QoS management allows administrators to configure settings that guarantee minimal disruptions, providing end users with a seamless viewing or gameplay experience.

Additionally, Cisco 8xDMT takes advantage of Multicast Domain Name System (mDNS), which allows devices on the same network to discover and communicate efficiently. This not only aids in reducing the network load but also simplifies the management of multicast addresses, making it easier for organizations to scale their operations without significant overhead.

The technology also incorporates robust security features, including support for secure multicast transmissions. This ensures that sensitive data remains protected during distribution, addressing the increasing need for security in an era where cyber threats are prevalent.

Furthermore, Cisco Systems emphasizes interoperability with its 8xDMT platform, ensuring easy integration with existing network infrastructure. This is crucial for enterprises looking to modernize their systems without the need for extensive reinvestment in new hardware.

In conclusion, Cisco Systems’ 8xDMT stands out as a versatile and high-performance multicast solution designed to meet modern networking demands. With its ability to manage multiple streams, enforce QoS, simplify multicast management, and secure communications, it holds significant potential for transforming how organizations distribute data efficiently and effectively.
