Ambassador ® T8110 PCI-Based H.100/H.110 Switch

and Packet Payload Engine

1 Introduction

The T8110 is Agere Systems Inc.’s newest addition

to the Ambassador series of computer telephony

integrated circuits. This device not only has the capa-

bilities of previous members of the Ambassador

series but also extends them by providing a flexible

interface for switching packet payloads between a

local PCI bus and the H.100/H.110 buses. Packets

may also be switched between the local PCI bus and

local TDM streams. This part is intended to work with

a coprocessor for providing header, framing, and

checksum generation. Since the T8110 operates

purely on payloads, multiple protocols such as IP,

ATM, and A-Bis can therefore be supported simulta-

neously. To reduce system integration costs, support

for non-PCI devices is provided through a minibridge.
