This field, located within parentheses next to the screen title, displays the current screen mode.

Port Status

These fields consist of the columns of numbered ports located under the device identifiers (MMAC24, STH24, et al). They display port-status information and let you selectively enable and disable ports when in the ADMINISTRATIVE mode.

Virtual Flexible Network Bus (VFNB)

Use this field (a quasi Network Bus), located at the top of each the port-status column under the device identifier, to either bypass or activate a module, or hub, when in the ADMINISTRATIVE mode.

Possible VFNB screen configurations for Enabled modules are described as follows:

•Attached left (<----): The module is connected via cabling to the next module. For example, the MicroMMAC-T configured as module 1 is connected to STH module 2

•Attached right (---->): The STH 2, for example, is connected to the MicroMMAC-T

•Attached left/right (<---->): The STH is connected to the STH or MicroMMAC-T before it and the STH after it.

•Detached (-----): The MicroMMAC-T is not connected to an STH module.
