Single WAN interface V.35 or X.21 (optional)

The V.35/X.21 WAN connector is located on a PCI card that offers a separate
DB28S connector that provides the signals needed to interface to V.35/X.21
equipment. Included in the accessory box is a cable that must be ordered
separately; one that maps the signals to a standard V.35 connector, or one that
maps the signals to an X.21 connector. You will need a DSU/CSU (digital service
unit/channel service unit) between the WAN connection and the Contivity. This
section documents the connector and cables used with the V.35 and/or those used
with X.21 WAN Synchronous Adapters.
The cables provided with the WAN PCI card enable the WAN adapter to function
as DTE (Data Terminal Equipment).
