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

The V.35 and X.21 WAN connectors are located on a PCI card that offers a
separate DB28S connector that provide the signals needed to interface to V.35 and
X.21.Included in the accessory box are two cables that map the signals to a
standard V.35 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 enables the WAN adapter to function
as DTE (Data Terminal Equipment).6Figure 6 shows the single V.35/X.21 WAN
interface.
