6.4.1Reasons for Upgrading Microcode

As part of your network operations plan, it is a good practice to include maintaining your network devices with the most recent software/microcode available. This allows you to take advantage of the newest features, to comply with the latest standards, and to interoperate with the widest number of vendors.

The latest microcode levels for the 8285 ATM Control Point are:

•Release 1.3.0

−Support for the A03-MB155 module.

−Additional LANE support including support for external LECS via either configured address or dynamic discovery.

•Release 1.4.0

Release 1.4.0 is a major upgrade. It includes new operating code as well as new microcode for the base unit and all available 8285 modules. New and enhanced features include:

−Increases the number of connections available per module from 992 to 4064.

−Allows for variable VPC/VCC value ranges enabling either more paths with fewer channels each, or fewer paths with more channels each.

−Supports ATM Forum Available Bit Rate (ABR) Service on the ATM 12-Port 25 Mbps UTP Concentrator Module, the ATM 3-Port 155 Mbps LAN Concentration Module, and on the 12-port 25 Mbps base unit.
