Note that the Rubicon-LH will employ the same industry leading EFEC code that was used in the AMCC Niagara device, making these devices totally compatible. DATA INTERFACES Both the Client and Network interfaces are SFI-4 compliant. Data is transferred as 16-bit LVDS parallel data with a synchronous clock. For 10 Gbps applications, both the Client and Network interface rate can vary between 622 Mbps and 705 Mbps, for an aggregate bandwidth of 9.95 Gbps to 11.28 Gbps. The defined low end of the parallel LVDS interface is 31.25 Mbps (across 4 bits of the interface) for an aggregate bandwidth of 125 Mbps. The device supports OC192/STM-64, ITU G.709 OTU-2, ITU-G.709 ODU-2, or proprietary direct map (into ODU-2) data up to a client rate of 10.519 Gbps.

Client and Line side loopback • Client side and line side loopback on the Rubicon. Support For System Test and Diagnostics • Can synthesize SONET frame. • Error injection capability for verification of remote error reporting. • Test-set compliant pseudo-random sequence generation/analysis. CLIENT PERFORMANCE MONITORING A SONET/SDH performance monitor supporting OC192/48/12/3 and SDH64/16/4/1 rates is provided to perform optional-section and limited-line termination functions. TOH for the SONET signal is dropped and added. On chip processing of the critical TOH functions, such as B1, B2, J0, is provided to enable functioning as a SONET/SDH network element. The performance monitor may also be configured to provide non-intrusive monitoring while transparently passing through the received signal with no overwrite. The 10 Gbps signal and the 2.5 Gbps signal may be synchronously or asynchronously mapped into the ODU-2 and ODU-1 payloads, respectively. FEC parity check bytes are then optionally added to form the OTU-2 or OTU-1. The device can also output the OTU-2 or OTU-1 with no parity check bytes. In the receive direction, data is de-mapped from the OTU-2 or OTU-1 and control signals are provided to enable timing regeneration of the client 10 Gbps or 2.5 Gbps signal. When operating in the ITU G.709 OTU-2/OTU-1 or ODU-2/ODU-1 mode, the SONET monitors can be bypassed. Unlike the Niagara device, the Rubicon-LH provides the capability for intrusive SONET/SDH performance monitoring inside the OTN frame. Onchip processing of the G.709 overhead is provided to enable single chip G.709 section termination. G.709 Overhead can be added or dropped as required. The remapping that is required for synchronization of asynchronous ODU-1 signals is supported. Client-signal monitoring for 8B/10B encoded data is also provided, as well as 64B/66B monitoring for 10GE-LAN traffic. A full 10GE-LAN MAC is also included in the Rubicon-LH device to support extensive 10GE monitoring. General Purpose Processor Interface • Glueless 16-bit interface to MPC860, 25 MHz to 66 MHz. • Dual mode interface also supports Intel processors. • Interrupt driven or Polled mode operation. Additional Protocol Support • FEC Frame Synchronous scrambling. • Programmable sequence detection. Pin Compatibility to NIAGARA device Low Power .13 u CMOS Technology • 1.2 Volt core operation. • 2.5 Volt I/O. APPLICATIONS • SONET/SDH OC48/STM-16 OC192/STM-64 DWDM transport systems and DWDM metro networks. • Transparent Add-Drop Multiplexing Transponder applications. • Protocol Transparent Transport. • IaDI to IrDI FEC transponder chip (6.2dB gain network to >8dB gain network). GENERAL DESCRIPTION The AMCC Rubicon-LH device is a wide-area and metropolitan transport device aimed at next generation applications, required transparent mapping, and enhanced error correction capability. The device utilizes the ITU G.709 frame and overhead structures to enable deployment of full OTN compliant network elements. Rubicon-LH will support two gain rates, the standard G.975 based rate of 6.2dB (raw optical coding gain), and AMCC’s proprietary EFEC code, rated at greater than 8dB (raw optical coding gain). 10GE-LAN MAPPING The Rubicon-LH device supports 5 distinct methods to map 10GE-LAN into OTU-2 for transport. The first is the same manner as supported in the Niagara; that is, the line rate will run at 7% above the client rate with the full 10GE-LAN being mapped into an expanded OTU-2 frame. In this mode, the line rate of the Rubicon 2 Empowering Intelligent Optical Networks RUBICON-LH 10GE & OC192/48/12/3 DW/FEC/PM and AsyncMap Device with Strong FEC Part Number S19227PBI-2 Product Brief Revision 1.0, March 2006 will be 11.1GHz. The second and third mapping methods are similar and involve GFP encapsulation directly into a standard rate 10.7GHz OTU-2 frame. The two methods employ different manners of client flow control to limit the client data rate so that correct encapsulation into the OTU-2 frame can take place. The first method of flow control we call “pre-emptive” flow control. In this mode the RubiconLH would assert flow control signals back to the client in regular intervals, thereby guaranteeing that the client not overflow the capacity of the OTU-2 frame. The second method allows for the user to place a fifo-fill line on the ingress client fifo inside the Rubicon-LH. When the fifo-fill line is crossed the Rubicon-LH will then assert flow control signals back to the client in order to bleed off the ingress client fifo. The fourth manner in which 10GE-LAN mapping is supported is through GFP into OC192C and then perhaps into the OTU-2 (or directly out as an OC192C). This allows for the client signal to be groomed through a traditional STS-based SONET/SDH switch that perhaps exists within an OTN cloud. Either of the previously described flow control methods can be employed in this mapping mode. A fifth manner of 10GE-LAN mapping is supported in the Rubicon-LH and involves the direct mapping of the client signal into a 10.7GHz OTU-2 frame. There is no flow control to rate limit the client in this mode. LOOPBACK FUNCTIONS Near-end and far-end loopback is supported for each of the client interfaces and for the line interface. This enables line and device testing and fault isolation. Each functional block may be bypassed as required to support the application. When all blocks are bypassed, the device allows transparent pass-through of client data (assuming synchronous inputs). Key status and alarm signals are provided to outside pins to enable rapid response to failure conditions. These include but are not limited to: LOS, OOF, LOF, B1 Errors, and FEC errors. Three interrupt pins, each with a mask register are provided to enable prioritization of interrupts and timely interaction with firmware. In addition to the loopback capabilities of the device, the RubiconLH also employs a unique port swapping capability allowing the physical ports on the device to be interfaced to either side of the FEC encoders. With this capability a customer can use the EFEC core on either physical port of the device. This capability increases the flexibility of a single board design used in a variety of modes. FORWARD ERROR CORRECTION CAPABILITY Two FEC options are supported on the 10 Gbps line side. The Rubicon-LH can support standard RS(255,239) FEC compliant with G.709, G.975, and compatible with the AMCC Hudson device. The device can also support an enhanced FEC algorithm that is applied using the same G.709 frame structure and data rate as used in the Hudson and Niagara devices, but providing more than 2 dB of additional coding gain (*measured at a BER of 1015 ). The Rubicon-LH device will operate in a mode where both encoders and decoders are working simultaneously, allowing for a single chip transponder to operate between two networks with different gain characteristics. AIS SUPPORT For applications in which the client signal is SONET or SDH, the Rubicon-LH can generate a SONET/SDH AIS on both the client ingress and the egress. For applications in which the client signal is G.709 compliant or for OTN regenerator applications, Line Fail and un-equipped OTN AIS is supported. For OTN edge applications, the device can be provisioned to provide either a SONET/SDH AIS or a OTN Generic AIS to the client. This facilitates convergence of the SONET/SDH and OTN functions into a single network element. LEGACY COMPATIBILITY As indicated above, the Rubicon-LH also supports operation in the G.975 mode. In this mode, the G.709 overhead processing can be inhibited and direct access to the non-framing bytes in the overhead column is provided through the pins on the device. The device can should be configured to operate in the 255,238 mapping mode with no stuff columns inserted in the FEC payload. ODU MAPPING ITU compliant client mapping of SONET OC192 or SDH STM-64 into the ODU-2 signals (and the corresponding 2.5G signals into an ODU-1) is supported whereby a stuff column is added to every G.709 sub-frame resulting in an ODU rate expansion of (239/237). The chip can be configured to insert the G.709 compliant stuff byte value or to insert user data into this column. The values assigned to the stuff bytes can be defined either from a register set on chip or from an external add-drop port. Coverage of these stuff columns in the BIP calculation or in the FEC is optional and can be enabled via software. When the no-coverage option is enabled, the BIP and parity check values are calculated as if the standard stuff values were present. A direct map mode is supported for ODU-2 and ODU-1 with no stuff columns to enable mapping with a 239/238 rate expansion. Start-of-frame signals are provided at the input and output ports to enable synchronization to the ODU. FOOTPRINT COMPATIBILITY In addition to the significant reuse of the Niagara register map in the Rubicon, the Rubicon will also be pin compatible with the Niagara device. Although the core power balls will be driven to a lower voltage (1.2V versus 1.8V), with careful board design considerations, the customer will be able to realize the Rubicon-LH device in sockets designed for the Niagara chip. This capability will allow the customer to use a more feature rich and lower power dissipation device in the target socket.

The interface supports both Intel and Motorola type microprocessors, and is capable of operating in either interrupt driven or polled-mode configurations. APPLICATION DIAGRAMS Figure 2: OC192/STM64 to OTU-2 Edge Transponder Figure 2 shows the Rubicon-LH in an edge transponder application. The client-side interface is achieved through the connection to a standard 300 Pin MSA SFI4P1 Transponder. On the network side, the AMCC S19235 and S3394 are used to provide a highperformance interface to the network side optics. This diagram is also the diagram for a mid-span transponder for either a standard FEC to standard FEC network or a standard FEC to enhanced FEC network. In either of these mid-span transponder applications, the client rate would increase from the standard SONET rate to the 7% overhead rate.

Once the Mekong aggregates the client 2.5G SONET/SDH signals into a OC192C/STM64 signal, this is then passed onto the Rubicon-LH which performs the OTN encapsulation and creates the FEC overhead. On the network side, the AMCC S19235 and S3394 are used to provide a high-performance interface to the network side optics.
