MBE Family Installation and Operation Manual Chapter 1 Introduction

Functional Description 1-9

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.

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).

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.

The MBE power supply provides required operating voltages. The power supply

input ranges between 100 VAC to 240 VAC.

The RJ-45 control port provides setup, configuration, and monitoring and

download interface using an asynchronous ASCII terminal as a terminal emulator.

Management

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.
