Preliminary specification
Universal Timeslot Interchange
SC4000
DEVICE OVERVIEW
The SC4000 Universal Timeslot Inter-
change is designed to provide the hard-
ware interface to the SCbus. Its primary
function is exchanging digital data be-
tween the Local bus serial port and the
SCbus serial port. A microprocessor
interface allows the host controller to
specify the timeslots and serial lines for
this exchange. Both the SCbus and the
Local bus can be programmed to oper-
ate at either 2.048 Mb/s, 4.096 Mb/s or
8.192 Mb/s.
As shown in Figure 1 , the destination
routing memory defines the Local Bus to
SCbus switch connection. There are 128
destination routing memory locations
— one for each Local Bus input channel.
The data stored in the destination rout-
ing memory selects the timeslot and
SCbus serial port connection for the
Local Bus input channel. The source
routing memory defines the SCbus to
Local Bus switch connection. There are
128 source routing memory locations —
one for each Local Bus output channel.
The data stored in the source routing
memory selects the time slot and SCbus
serial port connection for the Local Bus
output channel.
