Default Bridge

Mode

Default Bridge Mode Default Bridge Mode is designed for those who want to use their Overview OfficeConnect Remote 840 to function as a bridge automatically, with no

special configuration or software installation required. This mode preconfigures the unit to bridge all packets.

In this mode, you will not be required to use Setup Wizard or install any software from the CD unless you want to change the configuration (you can install from the CD at any time).

There are several different settings for Default Bridge Mode. The different settings control the WAN operational mode; ATM or Frame Relay, and the VPI/VCI or DLCI settings.

If you set the OfficeConnect Remote 840 to this mode and no configuration exists, the OfficeConnect Remote 840 will automatically set up a bridge network on the Ethernet and will create a VC profile that bridges using RFC 1483 or RFC 1490 encapsulation with various VPI/VCI or DLCI values (see “DIP Switch Modes” table in Chapter 1 for details on how to set your router switches to obtain the correct VPI/VCI values for your configuration).

Your OfficeConnect Remote 840 was set in Unconfigured Mode (all switches OFF) before shipping.

The following settings are preconfigured:

Bridge network on the LAN Interface

A remote site profile named “Bridge” is set up to bridge all traffic and to use network service RFC 1483, one of several VPI/VCI values, and Unspecified Bit Rate (UBR).
