1.2 Description
These products in the
Ambassador
T8100 family pro-
vide a complete time-slot switch and an interface for
the H.100/H.110 time-division multiplexed (TDM)
buses. The T8100 family includes devices with hier-
archical switching as well as a capacity of up to 512
local to H.100 connections. The hierarchical switch-
ing allows up to 1024 local connections without using
H.100 bus bandwidth. The family also includes the
T8102 device for a low-cost solution in nonhierarchi-
cal systems.
All three TSI chips are backward compatible with the
bus standards
MVIP-90
and
Dialogic's
®
SC-Bus, as
well as supporting the newer standards, H-MVIP and
ECTF H.100. Other features include a built-in PLL for
H.100,
MVIP,
or SC-Bus clock operation in master or
slave clock modes and two independently program-
mable groups of up to 12 framing signals each. Pack-
aged in both a 208-pin SQFP and a 217-ball BGA,
the T8100 TSI devices provide an economic solution
for the computer telephony market.
