- The MBE Family is part of the LAN RANger Series of
Ethernet Remote Access Routers that provide cost effective remote access
connectivity for SoHo (Small office Home office) applications.
- The MBE Family supports remote access routing
and bridging for connecting remote PCs or LANs to a central LAN
over a wide variety of WAN interfaces and services, including ISDN,
Frame Relay, Leased Line, dial up modems, and DDS.
- Routing and bridging are performed on a
link-by-link basis. There are no bridging or routing limitations on the
central LAN. However, additional bridges should not be connected to
the remote LAN.
- IP can be routed over PPP, SLIP, CSLIP or
IPX can be routed over PPP or Frame Relay.
- Router links can operate opposite any PPP
standard compliant device, including third party routers and software
based PPP dialers (e.g., Windows 95).
- Bridge links are transparent to layer 3 protocols,
such as NetBIOS and DECNET.
- The Single IP address translation feature
allows a small or medium office LAN to connect to the Internet using a
single, dynamically or statically allocated IP address from the central
- For router links, the IP parameters and the
configuration file are learned automatically from any BOOTP server
via standard BOOTP protocol.
- Transparent remote to remote forwarding
enables direct data transfer between links whether the links are bridge or
router (see Figure 1).
- Multilink PPP support enables use of ISDN at
- The MBE family includes the following models:
- MBE10-1, single link router
supporting a single remote station for bridge links or full LAN segment
for router links.
- MBE10-1D, dual link router supporting a
single remote station on each bridge link or a full LAN segment on each
- MBE10-8, single link router supporting a
remote Ethernet LAN of up to 80 workstations on bridge links or a full LAN
segment on router links.
- MBE10-8D, dual link router supporting a
remote Ethernet LAN of up to 80 workstations on each bridge link or a full
LAN segment on each router link.
- Both the LAN and WAN link interfaces are modular,
and accommodate several standards.
The Ethernet/802.3 LAN interface options supported are:
- AUI (10Base5)
- BNC (10Base2)
- UTP Ethernet (10BaseT).
WAN link interface modules include:
- V.24/RS-232, which can be configured for asynchronous operation
over dial-up modem links. These links operate at data rates from 2.4 kbps
to 115.2 kbps. Use of compression modems improves performance and
throughput of the MBEs.
- Digital interfaces (V.24/RS-232, V.35, X.21, RS-530 and V.36) for
synchronous leased lines at data rates up to 1.5 Mbps
- Built-in CSU/DSU for connection to leased lines operating at up to 56
- An internal ISDN terminal adapter module. Two B channels are available
on the dual port module as well as one redundant link (sync/async). ISDN
switches supported include 5ESS, and DMS-100. The ETSI NT1 European
standard, and I430 are also supported.
- A built-in 4-wire, short range modem. This option permits
operation at data rates up to 768 kbps (See Figure 5, and Table 1). It is
suitable for campus or factory environments where either a single station
or a workgroup LAN requires connection to the LAN, beyond the distance
normally attainable over copper media. The 4 wire interface model has an
internal clock with selectable data rates from 16 kbps to 768 kbps
according to the required range.
- Quick setup and configuration is performed
via terminal emulator attached to control port or by using TELNET
access into the device over the LAN or WAN.
- An SNMP agent provides in-band or
out-of-band management by RADview or any other standard SNMP management
- An SNMP agent provides management by RADview
or any other standard SNMP management station.
- An integral Solid Firewall protects an
office LAN from undesired entry from the Internet, using session based
- PAP/CHAP security is provided for users
utilizing router links.
- Dialback over PPP to a station using a
router link at a fixed location is supported in Microsoft environments
(e.g., opposite Windows 95). This adds security by verifying user identity
and location. The dialback feature helps reduce costs to mobile users.
- Internet Access authentication is provided
by PAP/CHAP and the Scripting Tool.
- Undesired Access to the WEB RANger via
TELNET or SNMP can be blocked or password protected.
- Connection On Demand (COD) allows links to
be connected or disconnected according to time, traffic or management. COD
may be triggered based on user defined masks.
Spoofing is used to reduce WAN link up-time
and traffic by increasing the period between RIP, SAP, or IPX Keep Alive
Filters based on user definable masks improve
WAN utilization by ensuring that only necessary packets are transmitted
over the WAN. To ensure high performance and easy installation, a special
hardware filtering technique is used.
- MBE is supplied as a stand alone unit. Special
hardware for mounting either a single unit or two units side-by-side in a
19" rack, using minimal rack space of 1U (1.75") in height, can be ordered
separately (see ORDERING).
