Chapter 2 Cards Specifications

2.2.1 Common Control Cards

The node database, IP address, and system software are stored in TCC2P card nonvolatile memory, which allows quick recovery in the event of a power or card failure.

The TCC2P card performs all system-timing functions for each ONS 15454. The TCC2P card monitors the recovered clocks from each traffic card and two BITS ports for frequency accuracy. The TCC2P card selects a recovered clock, a BITS, or an internal Stratum 3 reference as the system-timing reference. You can provision any of the clock inputs as primary or secondary timing sources. A slow-reference tracking loop allows the TCC2P card to synchronize with the recovered clock, which provides holdover if the reference is lost.

The TCC2P card supports 64/8K composite clock and 6.312 MHz timing output. The TCC2P card monitors both supply voltage inputs on the shelf. An alarm is generated if one of the supply voltage inputs has a voltage out of the specified range.

Install TCC2P cards in Slots 7 and 11 for redundancy. If the active TCC2P card fails, traffic switches to the protect TCC2P card. All TCC2P card protection switches conform to protection switching standards when the bit error rate (BER) counts are not in excess of 1 * 10 exp - 3 and completion time is less than 50 ms.

The TCC2P card has two built-in Ethernet interface ports for accessing the system: one built-in RJ-45 port on the front faceplate for on-site craft access and a second port on the backplane. The rear Ethernet interface is for permanent LAN access and all remote access via TCP/IP as well as for Operations Support System (OSS) access. The front and rear Ethernet interfaces can be provisioned with different IP addresses using CTC.

Two EIA/TIA-232 serial ports, one on the faceplate and a second on the backplane, allow for craft interface in TL1 mode.

2.2.1.3 MS-ISC-100T Card

The MS-ISC-100T Ethernet LAN card (see Figure 2-3), which is a 12-port NEBS3 Ethernet Switch running Cisco IOS. The MS-ISC-100T card must be equipped in an NC shelf; the preferred slots are 6 and 12. MS-ISC-100T Cisco IOS configuration is part of the software package and is automatically loaded to the card at start-up. This configuration can be modified using the Cisco IOS command-line interface (CLI) only. The CLI is disabled by default, but it can be enabled from the Cisco Transport Controller (CTC) interface. All MS-ISC-100T ports are turned on by default. Using the CLI, you can turn off ports that are not used.

15454 specifications

Cisco Systems' 15454 is a leading optical networking platform designed to address a range of connectivity needs for service providers, enterprises, and data centers. As part of the Cisco ONS (Optical Networking System) portfolio, the 15454 provides advanced capabilities that cater to the evolving demands of high-performance network requirements.

At its core, the Cisco 15454 is built for scalability and versatility. It supports a variety of transmission methods, including SONET (Synchronous Optical Networking), SDH (Synchronous Digital Hierarchy), and WDM (Wavelength Division Multiplexing). This flexibility makes the platform ideal for deploying both legacy services and next-generation applications.

One of the standout features of the 15454 is its ability to support high-capacity wavelengths, allowing for greater bandwidth utilization across fiber networks. With advanced Dense Wavelength Division Multiplexing (DWDM) technology, the platform ensures efficient use of the available fiber and extends the distance over which data can be transmitted. This results in reduced operational costs while maximizing throughput.

The Cisco 15454 also comes equipped with an array of interfaces supported by its modular design. The platform can accommodate Ethernet, SONET/SDH, and IP services, which means it can seamlessly handle a wide range of protocols. The modular architecture allows network operators to tailor the system to their specific requirements, offering a variety of line cards and interfaces to choose from.

Another critical characteristic of the 15454 is its built-in protection mechanisms. The system offers diverse and automatic protection schemes such as optical Layer 1 protection, ensuring high availability and network resilience. This capability is essential for mission-critical applications where uptime is paramount.

Moreover, the platform is complemented by Cisco's sophisticated management solutions, which streamline the operational management of the network. With tools that provide in-depth monitoring and troubleshooting capabilities, network administrators can maintain optimal performance and quickly respond to any issues that may arise.

In summary, the Cisco Systems 15454 is a robust and adaptable optical networking solution. Its main features, including advanced DWDM capabilities, modular architecture, protocol versatility, and enhanced protection mechanisms, make it a preferred choice for organizations looking to scale their network infrastructure while ensuring high service reliability and performance. Whether for expanding bandwidth or modernizing legacy networks, the Cisco 15454 stands out as a powerful tool in the ever-evolving landscape of telecommunications.
