Handling Energized Products
General Safety Practices
Do not touch or tamper with the power supply when the power cord is connected. Line voltages may be present inside certain products even when the power switch (if installed) is in the OFF position or a fuse is blown. For DC-powered products, although the voltages levels are usually not hazardous, energy hazards may still exist.
Before working on equipment connected to power lines or telecommunication lines, remove jewelry or any other metallic object that may come into contact with energized parts.
Unless otherwise specified, all products are intended to be grounded during normal use. Grounding is provided by connecting the mains plug to a wall socket with a protective earth terminal. If an earth lug is provided on the product, it should be connected to the protective earth at all times, by a wire with a diameter of 18 AWG or wider. Rack-mounted equipment should be mounted only in earthed racks and cabinets.
Always make the ground connection first and disconnect it last. Do not connect telecommunication cables to ungrounded equipment. Make sure that all other cables are disconnected before disconnecting the ground.
Connection of AC Mains
Make sure that the electrical installation complies with local codes.
Always connect the AC plug to a wall socket with a protective ground.
The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.
Always connect the power cord first to the equipment and then to the wall socket. If a power switch is provided in the equipment, set it to the OFF position. If the power cord cannot be readily disconnected in case of emergency, make sure that a readily accessible circuit breaker or emergency switch is installed in the building installation.
Connection of DC Mains
Unless otherwise specified in the manual, the DC input to the equipment is floating in reference to the ground. Any single pole can be externally grounded.
Due to the high current capability of DC mains systems, care should be taken when connecting the DC supply to avoid short-circuits and fire hazards.
DC units should be installed in a restricted access area, i.e. an area where access is authorized only to qualified service and maintenance personnel.
Make sure that the DC supply is electrically isolated from any AC source and that the installation complies with the local codes.
The maximum permissible current capability of the branch distribution circuit that supplies power to the product is 16A. The circuit breaker in the building installation should have high breaking capacity and must operate at short-circuit current exceeding 35A.
Before connecting the DC supply wires, ensure that power is removed form the DC circuit. Locate the circuit breaker of the panel board that services the equipment and switch it to the OFF position. When connecting the DC supply wires, first connect the ground wire to the corresponding terminal, then the positive pole and last the negative pole. Switch the circuit breaker back to the ON position.
A readily accessible disconnect device that is suitably rated and approved should be incorporated in the building installation.

TNV-3 Telecommunication Network Voltage-3:
Ports whose normal operating voltage exceeds the limits of SELV (usually up to 120 VDC or telephone ringing voltages), on which overvoltages from telecommunication networks are possible.
Always connect a given port to a port of the same safety status. If in doubt, seek the assistance of a qualified safety engineer.
Always make sure that the equipment is grounded before connecting telecommunication cables. Do not disconnect the ground connection before disconnecting all telecommunications cables.
Some SELV and non-SELV circuits use the same connectors. Use caution when connecting cables.
Extra caution should be exercised during thunderstorms.
When using shielded or coaxial cables, verify that there is a good ground connection at both ends. The earthing and bonding of the ground connections should comply with the local codes.
The telecommunication wiring in the building may be damaged or present a fire hazard in case of contact between exposed external wires and the AC power lines. In order to reduce the risk, there are restrictions on the diameter of wires in the telecom cables, between the equipment and the mating connectors.
Ph:727-398-5252/Fax:727-397-9610 www.bestdatasource.com
Caution
Attention
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cords.
Pour réduire les risques s’incendie, utiliser seulement des conducteurs de télécommunications 26 AWG ou de section supérieure.
Some ports are suitable for connection to intra-building or non-exposed wiring or cabling only. In such cases, a notice will be given in the installation instructions.
Do not attempt to tamper with any carrier-provided equipment or connection hardware.
Electromagnetic Compatibility (EMC)
The equipment is designed and approved to comply with the electromagnetic regulations of major regulatory bodies. The following instructions may enhance the performance of the equipment and will provide better protection against excessive emission and better immunity against disturbances.
A good earth connection is essential. When installing the equipment in a rack, make sure to remove all traces of paint from the mounting points. Use suitable lock-washers and torque. If an external grounding lug is provided, connect it to the earth bus using braided wire as short as possible.
The equipment is designed to comply with EMC requirements when connecting it with unshielded twisted pair (UTP) cables. However, the use of shielded wires is always recommended, especially for high-rate data. In some cases, when unshielded wires are used, ferrite cores should be installed on certain cables. In such cases, special instructions are provided in the manual.
Disconnect all wires which are not in permanent use, such as cables used for one-time configuration.
The compliance of the equipment with the regulations for conducted emission on the data lines is dependent on the cable quality. The emission is tested for UTP with 80 dB longitudinal conversion loss
(LCL).
Unless otherwise specified or described in the manual, TNV-1 and TNV-3 ports provide secondary protection against surges on the data lines. Primary protectors should be provided in the building installation.
The equipment is designed to provide adequate protection against electro-static discharge (ESD).
However, it is good working practice to use caution when connecting cables terminated with plastic connectors (without a grounded metal hood, such as flat cables) to sensitive data lines. Before connecting such cables, discharge yourself by touching earth ground or wear an ESD preventive wrist strap.

Applications
MBE can be used in a wide range of applications, employing diverse communication links and LAN equipment. For more details on typical MBE applications, see the
LAN RANger Series Configuration Guide .
Features
•
MBE10-8D
is a dual WAN-port router/bridge, As a bridge, it allows connection of two remote Ethernet LANs, each consisting of up to 80 workstations to a central Ethernet LAN. As a router, it allows connection of a remote Ethernet
LAN.
The MBE serial link interface options are: V.35, V.24/RS-232, V.36/RS-422, X.21,
RS-530, 4W, ISDN and CSU/DSU.
Routing and Bridging Support
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. This includes 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.
•
Router links can operate opposite any PPP standard compliant device, including third party routers and software-based PPP dialers, such as
Windows 95.
• Bridge links are transparent to Layer 3 protocols, such as NetBIOS and
DECNET.
A backup link may be defined, which will be automatically activated if a failure occurs on the main link.
Management
Setup and configuration can be carried out from an ASCII terminal or PC terminal emulator connected to the control port, from any SNMP management station, such as RADview, or through TELNET (see the
LAN RANger Series Configuration
Guide
).
IP/IPX Support
Internet Protocol (IP) specifies support or MTU (Maximum Transmission Unit) fragmentation and reassembly of packets to form datagrams. The MTU defines the limit on fragment size transmitted on a physical network. The local terminal must support the reassembly of IP packets in order to read the IP datagram.
MBE supports networks that have multiple IP nets on the LAN.

MBE Family
Installation and Operation Manual Chapter 1 Introduction
The Single IP address translation feature permits a small or medium office LAN to connect to the Internet or Intranet transparently. Single IP uses a single, dynamically or statically allocated IP address for all users on the LAN.
•
IP can be routed over PPP, SLIP, CSLIP or Frame Relay.
•
IPX can be routed over either PPP or Frame Relay.
Quick Setup
The Quick Setup menu enables the adjustment of setup and link configuration parameters while MBE is operating. For a complete description of the Quick Setup menu, see the
LAN RANger Series Configuration Guide
.
Transparent Remote-to-Remote Forwarding
Transparent remote-to-remote forwarding enables direct data transfer between two remote sites, whether or not the links are bridges or routers.
Security
Unauthorized entry to an office LAN is prevented by an Integral Solid Firewall using session-based firewalls. When enabled, access to the LAN is restricted to only applications enabled via the Firewall Forward Application List. In addition, access to the MBE unit can be blocked or password-protected through TELNET or SNMP.
MBE uses PAP/CHAP security for applications that include router links. PAP/CHAP and a scripting tool provide Internet Access authentication.
Dialback over PPP to a station using a router link at a fixed location is supported in
Microsoft operating environments (such as Windows 95). This feature adds security by verifying the user's identity and location. It also reduces costs to mobile users.
MBE also supports Remote Dial-In User Service (RADIUS), which is a client/server security protocol. Security information is stored in a RADIUS server. MBE communicates with the RADIUS server to authenticate users.
WAN Economy
Connection on Demand (COD) enables links to be connected or disconnected according to time, traffic or management. COD may be triggered based on userdefined masks.
Spoofing is used to reduce WAN link up-time and traffic by increasing the period between RIP, SAP or IPX Keep Alive broadcasts.
Filters based on user-defined masks improve WAN utilization by ensuring that only necessary packets are transmitted over the WAN. A special hardware filtering technique is used to ensure high performance and easy installation.
ISDN Support
MBE supports applications operating over ISDN networks. ISDN software may be downloaded into flash memory via TELNET or SNMP.
A bandwidth threshold may be set in order to control the amount of traffic passing through ISDN lines. The first ISDN line operates according to the COD

Installation and Operation Manual configuration. If traffic exceeds the defined threshold, the second ISDN line will be connected.
Dual Image Flash Memory
Two different versions of software may be saved in two different partitions. At reset, MBE automatically runs the software stored in the primary partition. New software versions are stored in the secondary partition. If the software download is successful, the secondary partition becomes primary, and MBE resets, automatically running the new software version. If the download is not successful, the previous software version will continue to run.

Principles of Operation
MBE10-1 Operation
The remote MBE learns the address of the remote workstation connected to it when the workstation attempts to access the network. The remote MBE then uses this workstation address to request the local MBE to insert into the local (main)
LAN. The remote MBE forwards all frames originating from the remote workstation. The local MBE will forward to the link only those frames destined for the remote workstation including broadcast and multicast messages, unless they have been masked out.
MBE10-1D Operation
The remote MBE units on both links update the local MBE with the addresses of the remote workstation attached to it. Each remote MBE forwards to the link all frames destined for the local LAN. The local MBE forwards to a particular link only those frames destined for a workstation connected to that link. Broadcast and multicast messages are forwarded to both links, unless they have been masked out.

Installation and Operation Manual Chapter 1 Introduction
MBE10-8 Operation
On power-up, both the local and remote MBE10-8s will connect to their respective LANs. The remote MBE10-8 continuously learns the addresses of workstations on the remote LAN and updates the local MBE10-8 with these addresses (up to 80 addresses).
The remote MBE10-8 forwards all frames to the local LAN that are not addressed to workstations on the remote LAN. The local MBE10-8 forwards all frames that have destination addresses belonging to one of the remote workstations to the link.
Broadcast and multicast packets are always forwarded in both directions, unless they are masked out using the filtering tool (see the
LAN RANger Series
Configuration Guide
).
MBE10-8D Operation
Operational characteristics of MBE10-8D are identical, in most respects, to those of MBE10-8, except that MBE10-8D (located at the local LAN) supports connection of two remote LANs (one per link).
MBE10-8D supports up to 80 addresses per LAN providing a total of 160.
Broadcast and multicast packets are always forwarded in both directions, unless masked out using the filtering tool (see the
LAN RANger Series Configuration
Guide
). MBE10-8D can also be installed on a remote LAN where one link serves as a backup link to the other.

Installation and Operation Manual Chapter 1 Introduction
Bridge Mode Filtering Block (MBE10-8 and MBE10-8D only)
In addition to MBE10-1 functions, MBE10-8 and MBE10-8D have a filtering block.
The filtering block in the local MBE compares the destination address of every frame transmitted on the main LAN to the table of remote workstation addresses.
The result of the filtering block comparison generates a
copy/not copy frame
command for the LAN processor.
If a frame is addressed to one of the remote workstations, the local MBE forwards this frame to the link. The remote MBE compares the destination address of every frame transmitted on the remote LAN with the remote workstation address table.
All frames in the remote LAN, containing destination addresses not included in the remote workstation address table, will be forwarded to the link by the remote
MBE.
If the frame destination address is of the broadcast or multicast type, the filtering block compares the source address of the frame to the remote workstation address table. This source address check results in a
copy/not copy
command for the LAN processor.
Link Interface
The link interface provides the physical connection to either V.24/RS-232, V.35,
RS-530, V.36, 4W, X.21, ISDN or DDS links. The 4W interface provides an internal short range modem with internal clock. DCE mode is provided for bench testing by V.24 and V.35 link interfaces. In DCE mode, the internal clock rate can be adjusted by selecting options from the internal clock rate setup menu (see
"Internal Clock Rate Setup"
in the
LAN RANger Series Configuration Guide
).
Main Processor and Communication Processor
The main processor controls the LAN and communication processors. It performs buffer management and transfers the frames received from the LAN for transmission to the link and vice versa.
The communication processor provides an HDLC link for transmission and reception of frames to the main processor. Error checks and retransmissions ensure an error-free link.
Power Supply
The MBE power supply provides required operating voltages. The power supply input ranges between 100 VAC to 240 VAC.
Asynchronous Control Port
Management
The RJ-45 control port provides setup, configuration, and monitoring and download interface using an asynchronous ASCII terminal as a terminal emulator.
Quick setup and configuration is performed via a terminal emulator attached to the control port, or via TELNET access to the device over the LAN or WAN.
An SNMP agent provides in-band or out-of-band management by RADview or by any other standard SNMP management station.
Software downloading is available through the control port, using XMODEM, and through the LAN or WAN using TFTP. Parameter file downloading and uploading is available through the LAN or WAN using TFTP.
