Sniffer WANbook - network monitoring device

Network Associates' WANbook bridges the gap between WANs, LANs, and internetworks, providing a WAN's-eye view into internetworks. Utilising an Ethernet CardBus or PCI NIC connection to the PC, WANbook houses interchangeable Interface Modules that connect to T1, E1 or RS/V (i.e., V.35, RS-232), or an ISDN internetwork. The WANbook is the first in a new generation of WAN analysers that house their Interface Modules externally, allowing convenient connection to multiple WAN network types.
