ANA-5910/5930/5940 User’s Guide
The adapter delivers high performance in terms of low latency, high
throughput, and fast response time. The adapter supports
simultaneous inbound and outbound transfers at their maximum
line speed of either 25 Mbits/sec for the ANA-5910 or 155 Mbits/sec
for the ANA-5930/5940.
One of the adapter’s most important functions is to perform the
segmentation and reassembly of data for communication with the
ATM network. The adapter segments outgoing PDUs into ATM cells
and transmits them to an ATM switch for forwarding to their
destination. The adapter uses AAL 5 protocol to map PDUs into the
information field of the ATM cell. The adapter also reassembles
incoming cells into a larger frame and uses a buffer management
scheme for the efficient transfer of PDUs between the adapter and
the host computer.
At the physical layer, the ANA-5930/5940 supports the SONET/
SDH and STS-3c/STM-1 155-Mbit/sec physical transport standards.
The ANA-5910 conforms to the ATM Forum’s 25.6-Mbit/sec
standard transmission method.
