DLP- A554 Upgrade EC-1 Cards in a 1:1 Configuration to DS3/EC1-48 Cards

DLP-A554 Upgrade EC-1 Cards in a 1:1 Configuration to DS3/EC1-48 Cards

Purpose

This task upgrades low-density electrical cards in a 1:N protection

 

scheme (where N = 1 or 2) to high-density electrical cards

 

(DS3/EC1-48, DS1/E1-56, and DS3XM-12 cards). Low-density cards

 

are defined as DS-1 and DS3-12. This procedure also upgrades

 

low-density electrical cards (DS3XM-6 cards) in a 1:1 protection

 

scheme to high-density electrical cards (DS3XM-12 cards).

Tools/Equipment

DS3/EC1-48 card(s), as needed

 

DS3XM-12 card(s), as needed

 

DS1/E1-56 card(s), as needed

 

High-density shelf assembly (15454-SA-HD)

 

High-density EIA (MiniBNC, UBIC-V, UBIC-H) installed

Prerequisite Procedures

NTP-A17 Install the Electrical Cards, page 2-10

Required/As Needed

As needed

Onsite/Remote

Onsite

Security Level

Provisioning or higher

Note You cannot have any DS-1 cards installed on the same side of the shelf as the DS3/EC1-48 card when you finish the low-density to high-density upgrade.

Caution After upgrading a DS3XM-6 card to a DS3XM-12 card, the newly installed DS3XM-12 card will run in STS-12 mode. To change the backplane throughput rate, make sure the card is out-of-service and not carrying live traffic. Changing the backplane throughput rate on a in-service cardcan cause a traffic outage of up to 50 ms.

Step 1 Complete the DLP-A60 Log into CTC, page 17-69. If you are already logged in, continue with Step 2.

Step 2 According to local site practice, complete the “NTP-A108 Back Up the Database” procedure on page 15-5.

Step 3 Determine which low-density card(s) you want to upgrade to high-density, according to slot limitations.

Note For 1:N protection groups, the protect card is installed in Slot 3 on the A side of the shelf and Slot 15 on the B side. For 1:1 protect groups, working and protect cards can be installed in any traffic slot.

The following limitations apply if you are upgrading a low-density protect card:

•If you are upgrading an EC1-12 card in a 1:1 protection group to a DS3/EC1-48 card, the EC1-12 cards must be in either Slots 1 and 2 or 16 and 17.

•If you are upgrading EC1-12 cards in a 1:1 protection group to a DS3/EC1-48 card, Slot 3 needs to be unoccupied if upgrading on the A-Side, and Slot 15 needs to be unoccupied if upgrading on the B-Side.

Step 4 In node view, double-click the current protect card. The card view appears.

ONS 15454 specifications

Cisco Systems ONS 15454 is a versatile optical networking platform designed to enable service providers and enterprises to deploy and manage robust optical networks efficiently. The ONS 15454 serves as a cornerstone in the evolution of transport networks, featuring various technologies that meet the increasing demand for bandwidth and service quality.

One of the standout features of the ONS 15454 is its support for multiple service types, including TDM, Ethernet, and Wavelength Division Multiplexing (WDM). This capability allows service providers to maximize network resources while delivering a wide range of services, from traditional voice to high-speed data and video.

The ONS 15454 leverages Dense Wavelength Division Multiplexing (DWDM) technology, enabling the transmission of multiple data streams over a single optical fiber. This effectively expands the network's capacity without the need for additional infrastructure, a crucial benefit in today's ever-growing data landscape. The system supports a variety of transponder modules, allowing for flexible scaling and seamless upgrades as bandwidth requirements increase.

Scalability is another key characteristic of the ONS 15454. With its modular architecture, it accommodates a range of interfaces and line cards, making it easier to tailor deployments to specific customer needs. This modularity not only facilitates upgrades but also simplifies maintenance, minimizing downtime and operational costs.

The platform also features advanced management capabilities through Cisco's Optical Network Management system. This allows for real-time monitoring, provisioning, and troubleshooting, ensuring network reliability and performance. The intuitive interface and comprehensive reporting tools enable operators to gain insights into network operations, improving decision-making processes.

Furthermore, the ONS 15454 is built to support optical layer protection features, enhancing network resilience. Technologies such as Automatic Protection Switching (APS) and Optical Supervisory Channel (OSC) ensure that connectivity is maintained even in the event of a failure, crucial for mission-critical applications.

In conclusion, the Cisco ONS 15454 is a powerful optical networking solution that combines flexibility, scalability, and advanced management features. Its support for various services and technologies positions it as an essential asset for organizations looking to build a future-proof network capable of handling increasing data traffic while maintaining high service standards.
