Fast Ethernet Switches

PRODUCT

DATA SHEET

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.
