Flow-Through Timing

The transponder card allows the timing to “flow through” from client to line optical interfaces.

Receive timing from one interface (client or line) is used to time the other transmitter interface (line

or client). This flow-through timing enables the transported signal to remain independent from the

node timing.

Management

The Cisco ONS 15454 MSTP provides comprehensive management capabilities to support the

operations, administration, monitoring, and provisioning (OAM&P) capabilities through the

integrated Cisco Transport Controller craft interface with support from the Cisco Transport

Manager element management system (EMS). The 10-Gbps Full-Band Tunable Transponder Card

incorporates provisionable digital wrapper (G.709) functions, providing per-wavelength

performance management capabilities, especially for services being transported transparently

across the network. Without the digital wrapper functions, a carrier transporting a service

transparently would be unable to identify network impairments that may degrade the transported

signal and exceed SLA requirements. The digital wrapper’s GCC enables a separate

communications channel on a per-wavelength basis, versus the section DCC/regenerator section

DCC (SDCC/RSDCC) in SONET/SDH signals that is used by the platform when transparent

signals are transported. This GCC enables the Cisco ONS 15454 to extend its advanced network

auto-discovery capabilities to DWDM-based services. The integrated Cisco ONS 15454 Transport

Controller craft manager and the Cisco Transport Manager EMS provide the user with OAM&P

access for the system.

Configurable Far-End-Laser-Off Behavior

The 10-Gbps Full-Band Tunable Multirate Enhanced Transponder Card offers the flexibility to

provision the Far-End-Laser-Off behavior. You can use Cisco Transport Controller to configure

how the remote client interface will behave following a fault condition. It is possible to configure the

remote client to squelch or to send an alarm indication signal (AIS).

Performance Monitoring

The performance-monitoring capabilities of the 10-Gbps Full-Band Tunable Transponder Card

provide support for both transparent and nontransparent signal transport. For SONET/SDH-

terminated signals, standard performance-monitoring and threshold-crossing conditions and

alarms are supported per Telcordia GR-474, GR-2918, ITU G.783, and ETS 300 417-1 standards.

For 10 Gigabit Ethernet signals, standard performance parameters for transmit and receive signals

are based on RFC 2819. Each digital wrapper channel will be monitored per ITU-T digital wrapper

requirements (G.709). Optical parameters on the DWDM line interface are supported, including
