DESCRIPTION
The LAN TAPs operate in pairs. They "Tap" into the LAN cable at each end
and provide a separate signal path between the two devices over the unused cable
pairs, while allowing the LAN traffic to operate concurrently. A special
filter is employed to minimize cross talk within the cable.
On polled networks, many of these paths, from diverse locations, can be brought
back to the polling host and connected to a single port via a CPS Modem Sharing
Device. This concept can also be used at remote locations to allow networked
PCs to access the host via their serial ports and modems instead of a
bridge/router. This concept may also be considered to provide a RS-232 backup
path to the Host, even with a primary bridge/router connection.
Because the LAN TAP uses the physical layer of the LAN network, it does not
operate directly through logical devices such as HUBs, repeaters, bridges or
routers. In the event that this is a requirement, a By-Pass TAP adaptor can be
used to by-pass the logical device. It provides a direct copper link around
the logical unit while allowing the LAN signals to pass through it.
Several models are available that are compatible with standard Ethernet, Token
Ring or Unisys CTOS/BTOS, Cluster or TeleCluster twisted pair cabled network
(with CPS HUBs) and with CPS active patch panel HUBS for TDI or RS-232
(P-CONs).
