Single V.35 WAN Interface (Optional)
The Single V.35 WAN connector is located on a PCI card that offers a separate
DB26S connector that provides the signals needed to interface to V.35 equipment.
Included in the accessory box is a cable that maps the DB26S signals to a standard
V.35 connector. Table 3-1 shows the cable pinouts.
