ET100 LAN-WAN Bridge

When the HDLC packet is received on the remote side unit's data port,

The packet is checked for transmission errors, then the original

Ethernet packet(s) is recovered and sent out the remote's LAN port

completing the transmission. Here is the typical application of the

ET100.

Typical application of ET100 LAN-WAN Bridge.

Many times the ET100 is commonly referred to as an Ethernet to V.35,

Ethernet to X.21, or Ethernet to Datacom 'converter'. As a

sales/marketing term or non-technical reference, the term is OK.

However, from a technical standpoint, the term is a misnomer. The

Ethernet is not "converted" to V.35, it is run "over" the V.35 link.

Conversion also implies that the interface can work both ways. This is

NOT the case for the LAN-WAN Bridge as the following application

shows.

Application NOT ALLOWED for ET100.
