Ambassador
T8105
H.100/H.110 Interface and Time-Slot Interchanger
Introduction
The Agere Systems Inc.
Ambassador T8105 device
provides a complete solution for time-slot switching and
interconnect for the H.100/H.110 time-division multi-
plexed (TDM) buses. It is fully backwards compatible to
the T8100A and T8102 devices. The T8105 device pro-
vides hierarchical switching as well as a capacity of up
to 512 local to H.100/H.110 connections. The hierarchi-
cal switching allows up to 1024 local connections with-
out using H.100/H.110 bus bandwidth. Local interfaces
include sixteen serial inputs and sixteen serial out-
puts and the H-bus interface includes 32 bidirectional
H.100/H.110 streams. The T8105 bus interface is
compatible with the
MVIP*-90, H-MVIP, SC-Bus, and
ECTF H.100/H.110 bus standards. The
Ambassador
T8105 is configured via a microprocessor interface
which can also read and write time-slot and device data.
Packaged in both a 208-pin SQFP and a 217-ball BGA,
the
Ambassador T8105 TSI device can provide an
economic solution for the computer telephony market.

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:
s
Nibbles (4 bits)--representing a 32 kbits/s subrate
s
Dibits (2 bits)--representing a 16 kbits/s subrate
s
Bits--representing an 8 kbits/s subrate
H.100/H.110 data transfers are always bytes. If subrate
switching is used, the T8105 constructs a byte consist-
ing 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.
Onboard clock circuitry, including a digital phase-
locked loop, supports all H.100/H.110 clock modes
including
MVIP
and SC-bus compatibility clocks. The
local CHI supports PCM rates of 2.048 Mbits/s,
4.096 Mbits/s, and 8.192 Mbits/s. The
Ambassador
T8105 has internal circuitry to support either minimum
latency or multi-time-slot frame integrity. Frame integ-
rity is a requisite feature for applications that switch
wideband data (ISDN H-channels). Minimum latency is
advantageous in voice applications.

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 equip-
ment 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
interfaces 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 memory 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
computers.
With the advent of the H.100/H.110 bus specification
by the Enterprise Computer Telephony Forum
(www.ectf.org), the computer-telephony industry has
agreed on a single telecom bus for use with PCI and
compact PCI computers. H.100/H.110 facilitates inter-
operation of components, thus providing maximum
flexibility to equipment manufacturers, value-added
resellers, system integrators, and others building com-
puter-based telecommunications applications.
