10/100 Mbps Ethernet Switch
The Digi 5220 Family of two-port
10/100 Mbps auto-negotiating
Ethernet switches have either two
unshielded twisted pair (UTP) ports
or one UTP and one fiber optic port.
These switches provide an easy, cost-
effective method for migrating to Fast
Ethernet while preserving the
Ethernet LAN.
The 5220 Family functions as a
bridge, storing the address and
corresponding port number of each
incoming and outgoing packet in a
routing table capable of storing 4000
MAC addresses.
These converters use adaptive cut-
through switching based on a unique
algorithm. This switching procedure
dynamically changes data handling methods
based on the current error rate.
The 5220 Family starts with standard cut-
through switching for a clean data environment,
changes to fragment-free cut-through for a
moderate error rate environment, and progresses
to store-and-forward for a highly contentious
environment. Adaptive cut-through switching
delivers the best network performance in any
environment.
The 5220 effectively separates collision domains
and is an excellent front-end to repeaters
and hubs. International versions of the
5220 Family are also available.
