OVERVIEW
The Remote Mini Router is a high-performance, miniature
IP router. It’s based on a unique IP router chip and operates
with minimal software. Since the router is small and
inexpensive, it‘s ideal for cost-sensitive routing applications.
You need to configure only one software parameter for plug-
and-play operation.
The router works by taking each Ethernet frame from the
LAN and determining whether the IP packet is destined for
the IP net on the Ethernet LAN. If not, the Remote Mini Router
forwards the packet to the WAN link. IP packets received from
the WAN are automatically forwarded to the LAN if the IP net
matches.
Included are hardware filters that handle all filtering
operations at wire speed from both LAN-to-WAN and WAN-
to-LAN, without dropping a single packet. Filtering and
forwarding are performed at the maximum rate of 30,000 and
35,000 frames per second (wire speed), respectively. The buffer
can hold 256 frames with a maximum size of 1534 bytes and a
delay of one frame.
Along with a 10BASE-T (UTP) interface, the router is fully
IEEE 802.3/Ethernet v2 compliant and can also operate in full
duplex Ethernet applications.
A choice of WAN interfaces is available, including V.24,
V.35, V.36, X.21, RS-530, or a built-in fiber optic or 4-wire
modem.
Hardware-based traffic throughput control at rates of
64 kbps, 128 kbps, 512 kbps, 1 Mbps, or 10 Mbps are provided
by the router.
You can use the Remote Mini Router as a Frame Relay
Access Device (FRAD) with an integral IP router. RFC 1490
is supported for a single DLCI on the WAN link. Discovery
of the DLCI and the maintenance protocol is performed auto-
matically. This allows the Remote Mini Router to be used as
the termination unit of IP services over Frame Relay at the
customer premises, opposite a Frame Relay switch in the
backbone.
Alternatively, Point-to-Point Protocol (PPP) can be run on
the WAN link with automatic negotiation on power-up, as
well as support for PAP and CHAP authentication. With this
feature, the Remote Mini Router can operate opposite any
PPP-compliant access server or backbone router.
