High-Density OC-3 Intermediate Reach/STM-1
Short-Haul Cards for the Cisco ONS 15454 SONET/SDH Multiservice Provisioning Platform
The high-density eight-port OC-3/STM-1 card (Figure 1) delivers greater service densities and advances the system footprint on the Cisco ONS 15454 and Cisco ONS 15454 SDH multiservice provisioning platforms.
8-Port OC-3 IR/STM-1 SH Card
The Cisco ONS 15454 SONET/SDH Multiservice Provisioning Platform (MSPP) is the industry's leading MSPP. The Cisco ONS 15454 Synchronous Optical Network (SONET) and Cisco ONS 15454 Synchronous Digital Hierarchy (SDH) platforms are key building blocks in today's optical networks because they offer next-generation transport capabilities and economics. They provide supercharged multiservice transport capability by combining the best of a time-division multiplexing (TDM) system along with extensive Ethernet/IP data service offerings in a single platform. The Cisco ONS 15454 can aggregate traditional facilities such as asynchronous DS1/E1 or DS3/E3 circuits through OC-192/STM-64 along with data services, including 10BASE-T, 100BASE-T, or Gigabit Ethernet onto optical transport facilities such as OC-48/STM-16, OC-48/STM-16 dense wavelength-division multiplexing (DWDM), and OC-192/STM-64 line interfaces. The superior flexibility of the Cisco ONS 15454 enables drastically improved efficiencies in the transport layer and breakthrough cost savings for initial and life-cycle deployment.
Cisco Systems continues to expand service densities on the Cisco ONS 15454 with the introduction of the high-density, eight-port OC-3/STM-1 card. The eight-port OC-3/STM-1 card offers twice the density of the current four-port OC-3/STM-1 card and enables service providers to expand the number of revenue-generating service interfaces from an existing or new Cisco ONS 15454 network element. Enterprise users and service providers can also take advantage of lower overall network infrastructure costs by reducing the number of chassis and interface cards for future network build-outs.
The high-density, eight-port OC-3/STM-1 card provides eight transmit and eight receive optical interfaces on a single-width module. Each interface operates at the standard SONET/SDH (Telcordia GR-253-CORE and ITU G-703) 155.520-Mbps bit rate, intermediate/short-haul reach of 13 decibels (dB), over 1310-nanometer (nm) optics. Small form factor LC-style optical connectors provide the necessary density to terminate the eight signals on a single card. Each is angled down, relative to the faceplate, to reduce bend-related stress. Each OC-3/STM-1 port is provisionable to support unidirectional path switched ring (path protection)/subnetwork connection protection (SNCP), 1+1 automatic protection switching (APS)/MSP, or unprotected operation, providing networking flexibility for building access rings or aggregating traffic from terminal devices such as routers, ATM switches, or other SONET network elements. The card supports both concatenated (STS-3c) and non-concatenated (VT-1.5, VC-11/-12, STS-1/AU-3, VC-4) signals to enable transport of high-bandwidth data traffic as well as lower-speed services. In SONET mode, the optical ports can be provisioned as STM-1 to enable the tunneling of SDH payloads over a SONET network. This enables North American service providers to transport SDH traffic from international cable landing points to customer sites.
The high-density OC-3/STM-1 card incorporates faceplate-mounted LEDs to provide a quick visual check on the operational status at the card as well as the interface ports. A shelf-slot icon, a brown star, is printed on the faceplate to indicate the shelf slot where the card can be installed. The card is supported by the integrated Cisco ONS 15454 Transport Controller craft manager, which provides the user access for operations, administration, maintenance, and provisioning for the system.
High-Density OC-3/STM-1 Applications
The Cisco ONS 15454 system, deployed with the high-density OC-3/STM-1 card, enables a single-shelf assembly to terminate up to 64 unprotected or 32 protected OC-3/STM-1 interfaces. These interfaces can be used to aggregate services from multiple types of termination equipment (Figure 2) or aggregate bandwidth from multiple lower-speed access rings supporting governmental, business, or remote-facility access rings (Figure 3).
Multiple Ring Aggregation
With more than 1000 customers and 30,000 systems deployed worldwide, the Cisco ONS 15454 is the industry's leading multiservice provisioning platform. The Cisco ONS 15454 combines supercharged SONET/SDH transport, integrated optical networking (including ITU grid wavelengths and DWDM), and unprecedented multiservice interfaces to deliver radical economic benefits to service providers and enterprise users. The Cisco ONS 15454 offers the functionality of multiple network elements, including SONET/SDH multiplexing, DWDM, TDM, and Ethernet bandwidth management.
