® T8110 PCI-Based H.100/H.110 Switch

and Packet Payload Engine

Introduction

The T8110 is the newest addition to the

Ambassador

series of TDM switching and backplane interconnect

standard products. The T8110 can switch 4096

simultaneous time slots with 32 bidirectional local

streams and 32 bidirectional H.100/H.110 streams.

This device contains the capabilities of previous

members of the

Ambassador

series and also

extends them by providing a flexible interface for

switching packet payloads between a local PCI bus

and the ECTF H.100/H.110 buses. Packets may also

be switched between the local PCI bus and local

TDM streams.

Application Overview

The new features of the T8110 were designed specif-

ically for V oIP applications. The block diagram shown

is of a board that would make use of the PCI access

to the TDM memories. This part is intended to work

with a coprocessor for providing header , framing, and

checksum generation, but since the T8110 operates

purely on payloads, multiple protocols can be sup-

ported simultaneously such as IP, ATM, and A-Bis.

Support for non-PCI devices is provided through a

minibridge, reducing system integration costs. A typi-

cal application is shown in Figure 1 and provides

connectivity for framers, IP over Ethernet, and the

ECTF H.100/H.110 bus.

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

TDM Gateway

A typical application for the

Ambassador

T8110 switching and interconnect device is shown above. Data carried

over an OC-3 line is terminated with the Agere Systems Inc.

NetLight

2417G4A ATM/SONET/SDH optical

transceiver device. Within the Agere TMXF84622 Ultramapper, there are 84 T1/E1/J1 framers that deliver the

2,016 DSO channels from the OC-3 interface onto local TDM highways or streams. The

Ambassador

T8110

switches these 8-bit (64 kbits/s) time slots to onboard devices or onto the system backplane (8.192 Mbits/s) with

32 bidirectional local and 32 bidirectional backplane I/O streams. Once on the backplane, this traffic can be trans-

ported onto DSP resource cards where other

Ambassador

devices, such as the T8100A, T8102, and T8105 will

switch time slots to and from the system bus with encoding/decoding resources such as the Agere

StarPro

SP2000

DSPs. Traffic can be sent to additional resource cards in the system. Time slots containing signaling information

can be sent to resource cards with HDLC formatters. Similarly, TDM streams with voice data can be sent to

resource card s for echo/acoustical cancellation.
