Applications
The wide array of Physical Layer Modules and
Protocol Modules supports old and new applications
alike. On the user side, legacy interfaces such as
V.35/EIA-530 Packet and T1/E1 CBR protect your
investment in existing routers, codecs, LAN switches
and PBXs. Interfaces such as HSSI, T3/E3 and
OC-3c/STM-1 ensure support for newer bandwidth-
intensive applications.
On the network side, AACs connect to WANs at
speeds ranging from T1/E1 to OC-3c/STM-1. And to
fi ll the gap between T1/E1 and T3/E3, ATM Forum-
compliant Inverse Multiplexing for ATM (IMA) is
available. The IMA module aggregates up to eight
T1 or E1 lines into a single, logical link operating
at up to 16 Mbps. The module uses a round-robin
algorithm to divide traffi c evenly across multiple
links. Furthermore, if one or more links fails, the
traffi c is automatically redistributed among the
remaining links, providing redundancy in the network.
The AAC family also offers numerous options for
each protocol. For ATM UNI, both the Cell Protocol
Module (PM) and the Enhanced Shaping Cell PM
are available. The Cell PM is optimized for full
throughput on high-speed private networks and
local router or switch interfaces. The Enhanced
Shaping Cell PM is designed for use with public ATM
services, shaping each connection to ensure the
traffi c complies with carrier service level agreements.
Multiple PMs are available for Frame Relay services,
ATM DXI, PPP and HDLC packet traffi c. The Quad
Packet and Quad Packet/CBR PMs support packet
traffi c over T1/E1 and low-speed V.35. The Packet
PM supports packet traffi c over T3/E3, HSSI, and
high-speed V.35. All PMs support Frame Relay
Link Management and Frame Relay-to-ATM Service
Interworking (FRF.8) and Network Interworking (FRF.5).
For circuit emulation, there are four or eight ports
of structured or unstructured data transfer options.
The Quad Packet/CBR PM supports up to four ports
of unstructured circuit emulation on T1/E1 or V.35.
The Octal CES PM supports up to eight ports of
structured or unstructured T1/E1, up to four ports
of unstructured V.35 or one port of unstructured
T3/E3 or HSSI. The Octal CES PM also supports an
Adaptive Timing option.
The Ethernet PM and PLM pair supports RFC
1483/AAL5 bridging with the Spanning Tree
Protocol. The modules are designed for full-speed,
point-to-point Ethernet connections over ATM.
