Cisco IOS Software Configuration for the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

How to Configure the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

The prompt changes to interface configuration mode. The following example is for a 1-port channelized OC-12/STM-4 (DS3) line card in chassis slot 1:

Router(config)# interface serial 1/0:1

Router(config-if)#

Step 4 Specify framing by selecting the framing c-bitserial interface configuration command:

Router(config-if)# framing c-bit

Step 5 Enable payload scrambling by selecting the scramble serial interface configuration command:

Router(config-if)# scramble

Step 6 Assign an IP address and subnet mask to the interface with the ip address configuration command, as in the following example:

Router(config-if)#ip address 10.1.2.3 255.0.0.0

Step 7 Turn off keepalive messages:

Router(config-if)# no keepalive

Although some encapsulations benefit from keepalive processing (for example, HDLS), Cisco 12000 Series Routers do not require keepalive messages.

Step 8 Change the shutdown state to up and enable the interface:

Router(config-if)# no shutdown

The no shutdown command passes an enable command to the 1-port channelized OC-12/STM-4 (DS3) line card. It also causes the line card to configure itself based on the previous configuration commands sent.

Step 9 Add any other configuration commands required to enable routing protocols and adjust the interface characteristics.

Step 10 When you have included all the configuration commands to complete the configuration, type end or enter ^Z (hold down the Control key while you press Z) to exit configuration mode.

Step 11 Write the new configuration to memory:

Router# copy running-config startup-config

Router#

The system displays an OK message when the configuration has been stored.

After you have completed your configuration, you can check it using show commands. For an explanation of show commands, see the “Using show Commands to Check System Status” section on page 8.

Cisco Remote Connection Management

The 1-port channelized OC-12/STM-4 (DS3) line card consists of high-density DS3 service through 12 channels that provide DS3 interfaces through fiber-optic connectors for the Cisco 12000 Series Router. There are two sides to the network, a local (near-end) side and a remote (far-end) side. The 1-port channelized OC-12/STM-4 (DS3) line card supports three third-party DSU vendors (Digital-Link, Kentrox, and Larscom) and Internet Service Provider (ISP)-provided DS3 lines to enable connections between a router and another device.

OC-12/STM-14 specifications

Cisco Systems OC-12/STM-14 is a high-performance networking solution designed to meet the demands of modern telecommunications and data transport applications. Operating at a data rate of 622 Mbps, the OC-12 (Optical Carrier level 12) and STM-14 (Synchronous Transport Module level 14), this technology provides a reliable and efficient method for organizations to transmit large volumes of data over fiber optic networks.

One of the key features of the OC-12/STM-14 system is its capability for high-speed data transfer. This makes it an ideal choice for service providers looking to deliver broadband services, video streaming, and other bandwidth-intensive applications. With support for multiple protocols, including SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy), the OC-12/STM-14 can facilitate smooth communication and interoperability between various network devices.

Another significant characteristic of the OC-12/STM-14 is its scalability. Organizations can easily scale their networks by adding additional OC-12/STM-14 connections, accommodating their growing bandwidth needs without a complete overhaul of existing infrastructure. This flexibility is essential for businesses that expect fluctuations in data traffic or are anticipating future expansion.

Additionally, Cisco's OC-12/STM-14 employs advanced error correction and fault tolerance features, ensuring high reliability and minimal downtime. It supports sophisticated monitoring and network management capabilities, allowing administrators to proactively manage network performance and troubleshoot potential issues before they affect service quality.

Security is also a critical aspect of the OC-12/STM-14 architecture. Cisco incorporates robust security protocols to safeguard sensitive data during transmission, ensuring compliance with industry standards and protecting against unauthorized access.

In terms of compatibility, the Cisco OC-12/STM-14 integrates seamlessly with existing infrastructure and can work alongside various routing platforms. This compatibility significantly reduces the cost and complexity associated with upgrading legacy systems.

Ultimately, Cisco Systems OC-12/STM-14 offers a powerful solution for enterprises and service providers looking to enhance their networking capabilities. With its high-speed data transfer, scalability, reliability, and security features, it stands as a cornerstone technology in advanced telecommunications and data networking.
