Description
The AmbassadorT8102 is an H.100/H.110-compli-
ant device that provides a complete interface
between the H.100/H.110 bus and a wide variety of
telephony interface components, processors, and
other circuits. The bus interface provides all signals
needed for the H.100/H.110 bus, the H-MVIPand
MVIP-90 buses, or the SC-bus. Local interfaces
include sixteen serial inputs and sixteen serial out-
puts based on the Lucent concentration highway
interface (CHI). One built-in time-slot interchanger is
included. It supports up to 512 programmable con-
nections between any time slot on the H.100/H.110
bus and any time slot in the local switching domain.
The AmbassadorT8102 is configured via a micropro-
cessor interface. This interface can also read and
write time-slot and device data.
