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 fill 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 traffic evenly across multiple links. Furthermore, if one or more links fails, the traffic 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 traffic complies with carrier service level agreements.

Multiple PMs are available for Frame Relay services, ATM DXI, PPP and HDLC packet traffic. The Quad Packet and Quad Packet/CBR PMs support packet traffic over T1/E1 and low-speed V.35. The Packet PM supports packet traffic 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.
