Introduction
Product Overview
The Comtrol™ InterChangeVS™ 3000 virtual remote access server is a
rack-mountable or stackable “network appliance” that connects via
Ethernet to a host Windows NT
®
or Novell
®
NetWare
®
server and
terminates four Basic Rate Interface (BRI) ISDN lines. Each ISDN
line (“port”) consists of two 64 Kbps B channels and one 16 Kbps D
channel: each B channel can be used independently, for up to eight
simultaneous 64 Kbps connections, or the B channels can be bonded,
for connections of up to 512 Kbps. This bandwidth, along with the
flexible data compression schemes that are supported, makes the
VS3000 ideal for site-to-site file transfers and graphics-intensive
Internet/intranet applications.
