SWAN Concentrator Configuration Limits
WAN Ports and Communications Line Interface Processors
(CLIPs)
Three CLIPs are provided on a SWAN concentrator. Each CLIP has two WAN ports
that can run different communications protocols or electrical interfaces simultaneously.
For enhanced reliability, each CLIP has access to both Ethernet ports.
This figure shows the six WAN ports on the front panel of the SWAN concentrator.
Each WAN port has a 50-pin connector, which can support the RS-232, RS-449, X.21,
and V.35 electrical interfaces, although this connector does not physically match any of
the connectors used for these interfaces.
HP provides four types of interface converter cables to convert the 50-pin connector to
a connector that matches your interface. Each interface converter cable type supports,
both electrically and physically, one of the supported electrical interfaces. Four sense
pins in the 50-pin connector are wired to indicate which type of interface converter
cable is attached, enabling the SWAN concentrator to know which electrical interface is
connected.
