Product Overview

The Cisco® Timing, Communications, and Control Version Three (TCC3) card (Figure 1) provides a next-generation system processor for the Cisco ONS 15454 Multiservice Transport Platform (MSTP) while still being usable in the Cisco ONS 15454 Multiservice Provisioning Platform (MSPP). The Cisco TCC3 card performs system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP address detection and resolution, SONET and SDH data communications channel (DCC) termination, system DC input-voltage monitoring, and system fault detection. The card resides in slots 7 and 11 of the shelf assembly, providing 1:1 equipment protection.

The Cisco TCC3 card has more memory than the preceding TCC2 and TCC2P cards to accommodate extra features when used in a master Cisco ONS 15454 MSTP node. The TCC3 is only required when used as an MSTP master node when more than 12 shelves are subtended to it, and is recommended when subtending one or more Cisco ONS 15454 M6 nodes. The Cisco TCC3 can be used in all other Cisco ONS 15454 MSTP or MSPP applications but is not mandatory.

The Cisco TCC3 card incorporates a highly stable Stratum 3 internal timing reference to provide system timing based on input received from an external Building Integrated Timing Supply (BITS) source or from an incoming SONET or SDH optical signal. Synchronous status messaging helps the system to select the best timing sources, and a holdover mode maintains timing accuracy in the event that pre-provisioned synchronization references are not available.

Nonvolatile database storage for communication, provisioning, and system control is provided, allowing full database recovery and survivability with complete system power loss. In addition, short-term clock recovery is also supported, reducing the need to reset the calendar and time-of-day settings after a brownout or complete power outage.

The Cisco TCC3 card has two built-in interface ports for accessing the system: an RJ-45 connector and an RS-232. The RJ-45 port provides 10BASE-T Ethernet connectivity to the system, for local and remote access to the craft-management system, Cisco Transport Controller, through a common web interface. This port can also be used for interconnection to customer operations support systems (OSSs) and network management systems (NMSs), providing integration to external element management systems (EMSs), NMSs, and OSSs.

The Cisco TCC3 card provides additional security enhancements, allowing users to configure the front-panel and rear or Front Mount Electrical Connection (FMEC) Ethernet interfaces as regenerators or provision them with individual IP and MAC addresses for segregated craft and DCC access. The RS-232 port provides a serial ASCII interface for local craft access using VT100 emulation so that Transaction Language 1 (TL1) commands may be directly entered over a Telnet session without the assistance of a browser.

The front panel of the Cisco TCC3 card provides multicolored LEDs for a quick view of the status of the card activity, raised network alarms, shelf voltage input, LAN interface, and synchronization. Two front-panel buttons allow users to quiet an active external audible alarm (alarm-cutoff button) or test the working state of system LEDs. The Cisco TCC3 card is supported beginning with the Cisco ONS 15454 MSPP Release 9.2.0 system software for both the SONET and SDH platforms. Deployed networks may consist of nodes equipped with either Cisco Timing, Communications, and Control Plus (TCC+), TCC2, TCC2P, or TCC3 processor cards. Nodes operating with previous versions of TCC processor cards can be upgraded, in service, to the new Cisco TCC3, allowing migration to post-Release 4.0 software loads and possible future features. A Cisco TCC3 will appear like a TCC2P in releases prior to 9.2 and later than 4.x. In releases 4.x and prior, the card appears as a TCC2.

Features and Benefits

The Cisco ONS 15454 TCC3 card provides the following feature set:

   84 section DCC (SDCC) and multiplex section DCC (MSDCC) terminations allow the interconnection of multiring and linear systems on a single shelf assembly, reducing networking costs.

   84 SDCC tunnels or SDCC-to-line DCC (LDCC) tunnels provide interface flexibility for transparent transport of third-party DCC overhead channels.

   Integrated system input-voltage monitoring facilitates proactive identification of DC power-system issues.

   Time-and-date clock recovery after brownout or power loss prevents clock reprogramming.

   Complete shelf lamp test through faceplate pushbutton simplifies LED maintenance testing.

   Local and remote craft user access allows technicians to access nodes from anywhere.

   Local audible alarm cutoff squelches office audible or visual alert systems.

   Enhanced security capabilities through provisionable Ethernet ports allow better control over system- and network-level access.

The Cisco ONS 15454 MSPP equipped with TCC3 card performs like the TCC2P card:

   Multiservice capabilities: The Cisco ONS 15454 provides support for TDM-based, private-line interfaces (DS-1/E1, DS-3/E3, and OC-3/STM-1 through OC-192/STM-64) along with advanced 10/100/1000-Mbps Ethernet and future storage area network (SAN) interfaces, thus simplifying a service provider’s migration to new revenue opportunities and an enterprise’s multiple technology transport needs.

   Integrated, flexible optical networking: Optical transport speeds from OC-3/STM-1 to multiwavelength
OC-192/STM-64 are supported to allow the proper level of bandwidth to be deployed for the user application. Supporting in-service bandwidth upgrades and an integrated span upgrade wizard, the Cisco ONS 15454 allows the user to keep pace with growing network demands.

   Flexible architecture: The Cisco ONS 15454 supports ring, linear point-to-point, linear add/drop multiplexer (ADM), and mesh networking topologies to employ many technologies, including 2- and 4-fiber bidirectional line switched ring (BLSR) and multiplex section subnetwork protection ring (MS-SPR) with protection channel access, unidirectional path switched ring (UPSR) and subnetwork connection protection (SNCP), linear automatic protection switching (APS) and subnetwork connection (SNC), and Path Protected Mesh Networking (PPMN SONET only). Networks can be built using a combination of architectures and protection technologies to meet the needs of the defined services to be transported or delivered.

   Comprehensive and efficient network management: A full complement of TDM, SONET, and Ethernet statistics are provided to allow for the proper operation maintenance of the network. Additionally, network management is simplified through a common Data Communications Network (DCN) connection and user access to TDM, Ethernet, and optical operations, administration, maintenance, and provisioning (OAM&P) functions.

   Competitive initial and long-term costs: Advanced capabilities are only practical when a system is affordable enough to deploy and deliver a return on the investment. The Cisco ONS 15454 was designed for ease of use, therefore speeding installation time, decreasing personnel training requirements, and simplifying equipment maintenance. An integrated browser-based, point-and-click, craft user interface allows even an untrained user to quickly set up and provision services across an entire network using helpful networkwide provisioning wizards.
