• Manufacturer: AMCC [Applied Micro Circuits Corporation]

Niagara
OC-192/48/12/3 DW/FEC/PM and ASYNC Mapper Device
LEGACY COMPATIBILITY
As indicated above, the Niagara 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 should be configured to operate in the 255,238
mapping mode with no stuff columns inserted in the FEC pay-
load.
CONTROL INTERFACE
A general purpose 16-bit microprocessor interface is provided
for control and monitoring. The interface supports both Intel
and Motorola type microprocessors, and is capable of operat-
ing in either interrupt-driven or polled-mode configurations.

APPLICATION DIAGRAMS
Figure 2: OC-192/STM64 to OTU-2 Edge Transponder
Figure 2 shows the Niagara in an edge transponder applica-
tion. An AMCC S19211 CMOS SerDes device provides the
interface to the client-side optics. On the network side, the
AMCC S3193 and S3094 are used to provide a high-perfor-
mance interface to the network-side optics. This diagram is
also the diagram for a mid-span transponder for either a stan-
dard FEC to standard FEC network or a standard FEC to
enhanced FEC network. In either of these mid-span transpon-
der applications, the client rate would increase from the stan-
dard SONET rate to the 7% overhead rate.
