The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) (Figure 1) provides a comprehensive, intelligent dense wavelength-division multiplexing (DWDM) solution for expanding metropolitan (metro) and regional bandwidth
Figure 1. Cisco ONS 15454 Optical Service Channel Cards
Product Overview
The Cisco ONS 15454 MSTP incorporates an optical service channel (OSC) to provide a bidirectional channel connecting all the nodes in a DWDM ring. The OSC offers support for the following functions:
• Supervisory data channel (SDC) for node-to-node communications
• Distribution of synchronous clocking
• 100-Mbps user data channel
The OSC cards provide an OC-3/STM-1 formatted, 1510-nanometer (nm) signal inserted onto the fiber of a DWDM network outside the band for transmission signals (Figure 2). In nonamplified sites, the OSC-Combiner/Splitter Module (OSC-CSM) card provides access to the OSC received signal while expressing the remaining wavelengths and its transmitted signal is optically coupled into the fiber together with the transmitted wavelengths. In amplified sites, an OSC optical add/drop multiplexer (OADM) filter is integrated within the booster amplifier, providing the OSC wavelength to the OSCM (Optical Service Channel Module) card (Figures 3, 4, and 5). The OSC card's optical interface provides extended optical reach to meet the node-to-node distances found in typical metro and regional networks. The power levels of the OSC and composite express channels are controlled via software-controlled variable optical attenuators (VOAs) by the intelligent DWDM software of the Cisco ONS 15454 MSTP.

The Cisco ONS 15454 OSC cards are plug-in modules that take advantage of the proven Cisco ONS 15454 carrier-class features to maintain management connectivity for the Cisco ONS 15454 MSTP network. Table 1 describes the deployment applications of the OSC card.

Component
Deployment Application
OSCM
This card provides an internode communications channel for management and user data, Used in nodes with the booster amplifier, this card allows network-level communications to support intelligent DWDM implementation without the use of client transponder data-communication overhead.
OSC-CSM
This card provides an internode communications channel for management and user data, allowing network-level communications to support intelligent DWDM implementation without the use of client transponder data-communication overhead. It integrates an optical add/drop filter to remove and add the OSC wavelength while passing the other wavelengths. The OSC-CSM is used in nodes without a booster amplifier or future cross-connect equipped systems.
The Cisco ONS 15454 OSC cards incorporate faceplate-mounted LEDs, providing a quick visual check of the operational status at the card. Printed on each of the faceplates is an icon, either a green cross or an orange circle, which is matched to shelf-slot icons indicating the shelf slot where the card can be physically installed. The cards are supported by the integrated Cisco ONS 15454 Cisco Transport Controller craft manager, which provides the user access for operations, administration, maintenance, and provisioning (OAM&P) for the system.
