Viewing ATM Virtual Connection Cross-Connects
ATM networks are based on virtual connections over a high-bandwidth medium. By using
cross-connects to interconnect virtual path or virtual channel links, it is possible to build an end-to-end
virtual connection.
An ATM cross-connect can be mapped at either of the following levels:
• Virtual path—Cross-connecting two virtual paths maps one Virtual Path Identifier (VPI) on one port
to another VPI on the same port or a different port.
• Virtual channel—Cross-connecting at the virtual channel level maps a Virtual Channel Identifier
(VCI) of one virtual channel to another VCI on the same virtual path or a different virtual path.
Cross-connect tables translate the VPI and VCI connection identifiers in incoming ATM cells to the VPI
and VCI combinations in outgoing ATM cells. For information about viewing VPI and VCI properties,
see Viewing ATM VPI and VCI Properties, page 20-10.
