SONET/SDH/ATM OC-12 QUAD TRANSCEIVER

SONET OVERVIEW
Synchronous Optical Network (SONET) is a stan-
dard for connecting one fiber system to another at
the optical level. SONET, together with the Synchro-
nous Digital Hierarchy (SDH) administered by the
ITU-T, forms a single international standard for fiber
interconnect between telephone networks of differ-
ent countries. SONET is capable of accommodating
a variety of transmission rates and applications.
The SONET standard is a layered protocol with four
separate layers defined. These are:
Photonic
Section
Line
Path
Figure 5 shows the layers and their functions. Each
of the layers has overhead bandwidth dedicated to
administration and maintenance. The photonic layer
simply handles the conversion from electrical to opti-
cal and back with no overhead. It is responsible for
transmitting the electrical signals in optical form over
the physical media. The section layer handles the
transport of the framed electrical signals across the
optical cable from one end to the next. Key functions
of this layer are framing, scrambling, and error moni-
toring. The line layer is responsible for the reliable
transmission of the path layer information stream
carrying voice, data, and video signals. Its main
functions are synchronization, multiplexing, and reli-
able transport. The path layer is responsible for the
actual transport of services at the appropriate signal-
ing rates.
Data Rates and Signal Hierarchy
Table 1 contains the data rates and signal designations
of the SONET hierarchy. The lowest level is the basic
SONET signal referred to as the synchronous transport
signal level-1 (STS-1). An STS-Nsignal is made up
of N byte-interleaved STS-1 signals. The optical
counterpart of each STS-N signal is an optical carrier
level-Nsignal (OC-N). The S3038 chip supports OC-
12 rates (622.08 Mbps).
Frame and Byte Boundary Detection
The SONET/SDH fundamental frame format for
STS-12 consists of 36 transport overhead bytes fol-
lowed by Synchronous Payload Envelope (SPE)
bytes. This pattern of 36 overhead and 1044 SPE bytes
is repeated nine times in each frame. Frame and byte
boundaries are detected using the A1 and A2 bytes
found in the transport overhead. (See Figure 6.)
For more details on SONET operations, refer to the
Bellcore SONET standard document.
