Dual V.35 WAN Interface (Optional)
The Dual V.35 WAN connectors are located on a PCI card that offers two separate
DB26S connectors that provide the signals needed to interface to V.35 equipment.
Included in the accessory box are two cables that map the DB26S signals to a
standard V.35 connector. Figure 2-3 shows the Dual V.35 interface.
