Application Overview
The integration of computers and telecommunications
has enabled a wide range of new communications
applications and has fueled an enormous growth in
communications markets. A key element in the devel-
opment of computer-based communications equipment
has been the addition of an auxiliary telecom bus to
existing computer systems. Most manufacturers of
high-capacity, computer-based telecommunications
equipment have incorporated some such telecom bus
in their systems. Typically, these buses and bus inter-
faces are designed to transport and switch Nx64 kbits/s
low-latency telecom traffic between boards within the
computer, independent of the computer’s I/O and mem-
ory buses. At least a half dozen of these PC-based
telecom buses emerged in the early 1990s for use
within equipment based on ISA/EISA and MCA com-
puters.
With the advent of the H.100/H.110 bus specification by
the Enterprise Computer Telephony Forum, the com-
puter-telephony industry has agreed on a single tele-
com bus for use with PCI and compact PCI computers.
H.100/H.110 facilitates interoperation of components,
thus providing maximum flexibility to equipment manu-
facturers, value-added resellers, system integrators,
and others building computer-based telecommunica-
tions applications.
Subrate switching is the ability to switch part(s) of one
byte from one stream/time slot to another stream/time
slot. The parts are the following:
I
Nibbles (4 bits)—representing a 32 kbits/s subrate
I
Dibits (2 bits)—representing a 16 kbits/s subrate
I
Bits—representing an 8 kbits/s subrate
H.100/H.110 data transfers are always bytes. If subrate
switching is used, the T8100A constructs a byte con-
sisting of the subrate samples. The constructed byte
may contain any combination of nibbles, dibits, or bits.
In addition, individual data bits can be placed within a
byte along with don’t care bits.
