The Cisco Network Convergence System (NCS) 2000 Series, the Cisco ONS 15454 Multiservice Transport Platform (MSTP), and the Cisco Carrier Packet Transport platform share a common set of controller cards which perform system initialization, provisioning, alarm reporting, maintenance, diagnostics, IP addressing, data-communications-channel (DCC) termination, monitoring of system input voltage, system fault detection, and multishelf management connections. The line cards include the:

●   Cisco ONS 15454 Transport Node Controller (TNC) Card

●   Cisco ONS 15454 Transport Shelf Controller (TSC) Card

●   Cisco ONS 15454 Enhanced Transport Node Controller (TNCE) Card

●   Cisco ONS 15454 Enhanced Transport Shelf Controller (TSCE) Card

●   Cisco NCS 2000 Series Transport Node Controller (TNCS) Card

The TNC, TNCE and TNCS cards feature two optical service channel (OSC) ports that support a supervisory data channel (SDC), distribution of synchronous clocking, and a 100-Mbps user data channel (UDC). The TNCE, TSCE, and TNCS cards support the IEEE1588v2 Precision Timing Protocol (PTP) and time of day (ToD) with pulse per second (PPS), in addition to supporting Synchronous Ethernet (SyncE)/source-specific multicast (SSM). This is summarized in Table 1.

Table 1.       Controller Card Feature Differentiation

Common Features

All controller card versions incorporate a highly stable Layer 3 internal timing reference to provide system timing based on input received from an external BITS source or from an incoming SONET or SDH optical signal. Synchronous status messaging helps the system select the best timing sources, and a holdover mode maintains timing accuracy when preprovisioned 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 ToD settings after a brownout or complete power outage. A memory module is built into each ONS 15454 MSTP and NCS 2000 Series chassis and synchronized with the memory of the cards, thereby providing a backup to the node IP address, software package, and circuit database. This synchronization provides faster time to recovery when the node is used in simplex mode during a control-card replacement.

The cards have 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, providing local and remote access to the craft-management system, Cisco Transport Controller, through a common web interface. You can also use this port 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 cards provide enhanced security by allowing you to configure the front panel and chassis 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 you can enter Transaction Language 1 (TL1) commands directly over a Telnet session without the assistance of a browser.

The front panels of the cards multicolored LEDs for a quick view of the card activity status, raised network alarms, shelf voltage input, LAN interface, and synchronization. Two front-panel buttons allow you to quiet an active external audible alarm (alarm-cutoff button) or test the working state of system LEDs.

In the Cisco Network Convergence System 2015 (NCS 2015), Network Convergence System 2006 (NCS 2006), Cisco ONS 15454 M6 Multiservice Transport Platform (MSTP), and Cisco Carrier Packet Transport (CPT) 600, the cards can be equipped as active and standby, providing 1:1 equipment protection. In the Cisco Network Convergence System 2002 (NCS 2002), Cisco ONS 15454 M2 MSTP, and Cisco Carrier Packet Transport (CPT) 200, a single card is used in simplex mode.

Features and Benefits

The Cisco ONS 15454 TNC, TSC, TNCE, TSCE, and NCS 2000 Series TNCS cards provide the following features:

●   Integrated optical service channel (OSC): Each ONS 15454 TNC, TNCE, or TNCS card can be configured with one or two SFP ports to provide the OSC termination. In addition to OC-3/STM-1, the OSC can be configured with Fast Ethernet or Gigabit Ethernet for increased bandwidth and compatibility in future packet transport architectures.

●   Integrated multishelf management: The ONS 15454 TNC, TNCE, TSC, TSCE, and TNCS cards - coupled with the external connection unit (ECU) of the ONS 15454 M6, NCS 2006, or NCS 2015 - can support up to 50 subtended shelves in a cascade configuration without using an external switch or separate Ethernet switch card.

●   Eighty-four 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.

●   Eighty-four 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 problems.

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

●   A complete shelf lamp test through a faceplate pushbutton simplifies technician 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.

●   Through the Cisco ONS 15454 M6 External Connection Unit (ECU), the cards support connection to up to six subtended shelves or to the master shelf.

●   The cards support up to 24 dry-contact external alarms.

●   IEEE1588v2 Precision Timing Protocol with ToD and PPS is supported by the enhanced ONS 15454 TNCE and TSCE cards, as well as the TNCS card.
