ABSTRACT:
An OC3 to three DS3 SONET multiplexer is provided employing a field programmable gate array and other components in a single Type 400 mechanics card to achieve a form factor that is substantially reduced when compared to existing SONET multiplexers. The OC3 to three DS3 SONET multiplexer has integral optical redundancy and automated provisioning. Manual switches are provided to select continue/drop and line build out for each DS3. Switches are also provided for loopback options. The face plate for the multiplexer provides front access to all of the OC3 and DS3 connectors. The multiplexer is interchangeable with DS3 to DS1 multiplexer cards and WDM cards in a compact M13 SONET enclosure that is particularly useful at wireless cell sites.
