Prerequisites for the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

The Cisco 12000 Series Router must have at least one clock and scheduler card (CSC) installed that provides a one-quarter bandwidth to support the requirements of the 1-port channelized OC-12/STM-4 (DS3) line card.

Information About the 1-Port Channelized OC-12/STM-4 (DS3) Line Card

The 1-port channelized OC-12/STM-4 (DS3) line card provides 12 channels of DS3 multiplexed over a single 622-Mbps OC-12 port. The 1-port channelized OC-12/STM-4 (DS3) line card interfaces through an Add Drop Multiplexer (ADM) with other DS3 line cards at DS3 line rates in a configuration that usually consists of a Cisco 7200 Series Router and a Cisco 7500 Series Router configured with the packet-over-E3/T3 (POET) port adapter, or a third-party T3 data service unit (DSU) such as Digital Link, Larscom, or Kentrox.

The 1-port channelized OC-12/STM-4 (DS3) line card interfaces with the Cisco 12000 Series Router switch fabric and provides one OC-12 duplex SC single-mode intermediate-reach Synchronous Optical Network (SONET) connection.

Configuring the OC-12 Controller

Use the configure command to configure the new OC-12 controller. A Cisco 12000 Series Router identifies a controller by slot/port. The current OC-12 controller-configurable parameter settings are displayed as part of the show controller oc12 number/0 command, as in the following example:

Router# show controller oc12 1/0

OC12_CH_DS31/0

The current state of the controller is up

Current configurable parameter settings:

Clock source is LINE, Payload scrambling is ON

Loopback is NONE

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.
