Network Application Technology (NAT) LANB/280 Router

Product Description

	Network Application Technology's LANB/280  Remote IP Router provides an
affordable high performance solution for expanding Internet Protocol (IP)
networks to multiple remote locations.  The LANB/280 interconnects remote
LAN segments over telecommunications links.  LAN features and functions
are extended across wide  area networks in a way that is fully-compatible
with TCP/IP based applications.

	The Remote IP Router is ideal for connecting remote TCP/IP-only
subnetworks to multiprotocol routers attached to backbone network segments.
 It is designed for compatibility with Ethernet routers from other vendors
such as cisco Systems.  Because LAN traffic is routed rather than bridged,
remote performance is optimal since only essential network traffic is
transmitted over the WAN link.

	The remote Router is packaged in a double height stand-alone enclosure
with its own power supply.  Each Remote router provides one LAN connection
and one data link interface.  The router is available with a RS-232,
RS-449/422, V.35,  X.21, or G.703 link interface.  The Ethernet connection
may be AUI, thin Ethernet, or 10 Base-T.

	A pair of routers may be used to connect each remote Ethernet segment; 
one or both routers may be NAT's LANB/280.  Any synchronous link may be used
for remote connection, including analog or digital WAN  services, data
switches, T1 links (1.544 M bps),  Fractional  T1 services, or European E1
links (2.048 M bps).

Multi-Vendor Network Support

	The LANB/280 supports applicable networking standards to maximize
compatibility with multi-vendor networks.

	The Point to Point Protocol (PPP) is used for communications over the
serial link.

	The LANB/280 supports the Routing Information Protocol (RIP), used to
exchange network topology information with other routers in the network.

	Routing based on subnet masks is supported.  Subnet masks can be
configured.  A variety of ICMP services are supported.

Simple to Install and Operate

	The LANB/280 is a plug and play device.  Status lights provide 
continuous local display of LAN activity, bridge status, and link activity.  
The router may be configured through the network from a remote management
station or locally from an ASCII terminal attached to the serial port.

Affordable High Performance

	The LANB/280 is a low cost, highly-reliable, high performance remote
router.  Its performance is limited only by the speed of the remote
synchronous communications link.  Using a high speed T1 or E1 link, Remote
IP Routers support even the most demanding LAN applications such as data
base and graphics applications.

SNMP Network Management

The LANB/280 Remote IP Router provides SNMP agent support, and can be
monitored and managed by SNMP based network management stations from any
vendors.

NMS/100 Network Management

	The LANB/280 is a member of NAT's family of internetworking and network
management devices.  An NMS/100 Network Management System can monitor and
control LANB/280 Routers and other NAT devices in an internetwork
environment.

	The NMS provides an easy-to-use graphical interface for all network
management operation,  It continuously reports operational status and
detailed router statistics.
