PRELIMINARY SUMMARY DATASHEET
SONET/SDH STS-48/STM-16 Framer/Pointer Processor
Demultiplex Direction:
•Demultiplexes 4 x (STS-12/STM-4 or 4 STS-3/STM-1) tributar-
ies from an STS-48/STM-16 or bypass for
STS-48/STM-16-to-STS-48/STM-16 connection.
•Pointer Processor for all valid input combinations of
STS-48c/AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU4, or
STS-1/AU-3 signals.
•Configurable selector for choosing demultiplexed tributaries
from high-speed interface, low-speed interface, or from Protec-
tion inputs.
•Built-in 48x48 cross-connect for STS-1 level cross-connection
or add/drop.
•STS-48/STM-16 Framer.
•STS-48/STM-16 TOH (Regenerator and Multiplex sections)
Monitor.
•Provisionable TOH (Regenerator/Multiplex Sections) Genera-
tors for STS-12/STM-4 and/or STS-3/STM-1 outputs.
•STS-12/STM-4 and/or STS-3/STM-1 frame synchronous
scramblers.
Applications:
• ATM and POS (Packet over SONET) switches and routers.
• SONET/SDH add/drop multiplexers, terminal multiplexers,
and digital cross connects.
• WDM/DWDM Mux/Demux applications.
•SONET/SDH Mux/Demux,Transport Overhead Terminating
Transceiver, & Pointer Processors for STS-48/STM-16 and up
to 4 x STS-12/STM-4 or 16 x STS-3/STM-1s.
•Serial STS-12/STM-4 and STS-3/STM-1 interfaces.
•Provisionable as SONET or SDH on a per line basis.
•Packaged in a 624-pin CBGA.
Multiplex Direction:
•Multiplexes 4 x (STS-12/STM-4 or 4 STS-3/STM-1) tributaries
into an STS-48/STM-16 or bypass for
STS-48/STM-16-to-STS-48/STM-16 connection.
•Pointer Processors for all valid input combinations of
STS-48c/AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU4, or
STS-1/AU-3 signals.
•Configurable selector for choosing low-speed interface,
high-speed interface, or Protection inputs.
•Built In 48x48 cross-connect for STS-1 level cross-connection
or add/drop.
•4 x (STS-12/STM-4 or 4 STS-3/STM-1) or STS-48/STM-16
framers.
•TOH (Regenerator/Multiplex Sections) Monitors with provision-
able B2 signal Fail and Degrade detection algorithms.
•Provisionable TOH Generator for STS-48/STM-16 output.
•STS-48/STM-16 frame synchronous scrambler.
