The TE3-CHATT is a highly integrated protocol controller that implements HDLC, PPP
and transparent (TMA) protocol processing for 256 channels as well as frame alignment
for up to 28 T1 signals or 21 E1 signals. An integrated M13 multiplexer together with a
DS3 framer concentrates the data links for direct connection to a DS3 line interface unit.
pattern tests. An on-chip data management unit is optimized to transfer data packets via
a PCI interface by minimizing the bus load.
Note: The TE3-CHATT does not contain DS3 Line Interface Units.
