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

(Remainder of displayed text omitted from example)

Table 1 shows the default OC-12 controller configuration of a 1-port channelized OC-12/STM-4 (DS3) line card in a Cisco 12000 Series Router. In controller configuration mode, select an OC-12 controller for configuration using the controller oc12 slot/port command.

1-Port Channelized OC-12/STM-4 (DS3) Line Card Controller Configuration Default Values

 

 

 

 

Parameter

 

Configuration Command

Default Value

 

 

 

Clock source

[no] clock source [internal line]

line

 

 

 

Loop internal

[no] loopback [internal line]

no loopback

 

 

 

 

Shutdown

 

[no] shutdown

no shutdown

 

 

 

 

The following steps make up a basic controller configuration for the 1-port channelized OC-12/STM-4 (DS3) line card on a router.

Step 1 Enter global configuration mode by entering configure terminal at the privileged EXEC prompt:

Router# configure terminal

Router(config)#

Step 2 Enter controller configuration mode by entering the controller OC-12slot/port global configuration command and specify the router slot number and port number:

Router(config)# controller OC12 1/0

Router(config-controller)#

Step 3 Set the clock source by entering the clock source controller configuration command and specify line or

internal:

Router(config-controller)# [no] clock source {line internal}

Use the no form of this command to restore the default value, line.

Step 4 To change the OC-12 controller payload scrambling:

Router(config-controller)# [no] scramble

Use the no form of this command to remove scrambling. The default value is scrambling.

Step 5 To change the OC-12 controller loopback mode:

Router(config-controller)# [no] loopback {line internal}

Use the no form of this command to remove the loop.

Step 6 To change the shutdown state to up and enable the controller, enter the no shutdown controller configuration command:

Router(config-controller)# [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.

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.
