Multi-Service Access Processor Family
PXB 9101/9102/9201/9202
Infineon’s EasyPort is a comprehensive broad-
band communication processor family. Based on
a powerful 64-bit MIPS CPU core sub-system, the
EasyPort features packet and ATM cell process-
ing functionality for data and voice/data Integrated
Access Devices (IADs), small and medium enter-
prise gateways, access routers, and Voice over IP
(VoIP) gateways. The EasyPort family supports
T1/E1 framers, standard xDSL transceivers, and
10BaseS
TM
Ethernet over VDSL technology. Easy-
Port has the compute power and architecture to
support firewalls and Virtual Private Networks
(VPN), as well as future applications and new con-
nectivity options such as Wireless LANs and
Bluetooth
TM
.
When used in combination with VINETIC
TM
, Infin-
eon's system solution supports VoATM and VoIP
on the same hardware platform, and supports up
to 32 compressed voice channels.
Using the EasyPort processor family, communi-
cation system vendors gain a powerful set of
tools enabling the transportation of data, video
and voice services integrated on the same hard-
ware and software platform.
