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

Configuring the DS3 Serial Interface

After you verify the OC-12 controller configuration, you can configure the associated DS3 channel and serial interfaces on the OC-12 controller. Be prepared with the information you will need, such as the interface IP address.

The following sections describe how to enable an interface and specify IP routing. You may also need to enter other configuration commands, depending on your system configuration requirements. For descriptions of configuration commands and the configuration options available, refer to the appropriate software publications listed in the “Related Documents” section on page 19.

ACisco 12000 Series Router identifies an interface on the 1-port channelized OC-12/STM-4 (DS3) line card by its chassis slot number, line card port number, and DS3 channel number, in the format slot/port:channel. For example, the slot/port:channel# address of the first DS3 serial interface on a

1-port channelized OC-12/STM-4 (DS3) line card installed in line card slot 1 is 1/0:1. The port number is 0.

Table 2 shows the default DS3 serial interface configuration of an enabled line card. At the prompt, specify the new interface to configure by entering the interface command, followed by the type (serial) and slot/port:channel#.

Use the following procedures to configure the 1-port channelized OC-12/STM-4 (DS3) line card:

Step 1 Enter privileged EXEC mode by entering the enable command. The system will prompt you for a password if one is set.

Router> enable

Router#

Press the Return key after each configuration step, unless otherwise noted.

Step 2 Enter global configuration mode by entering the configure terminal command:

Router# configure terminal

Router(config)#

Step 3 At the global configuration mode prompt, specify the new interface to configure by entering the interface command, followed by the type (serial) and slot/port:channel# (line card

slot number/port number:channel number).

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.
