Abstract: A reduced size multiplexer and, in particular, a reduced size optical signal multiplexer module is provided for use in a reduced size enclosure. The optical signal multiplexer module has electrical and optical connectors on its faceplate to provide ease in access without having to remove the optical signal multiplexer from the enclosure. The optical signal multiplexer circuit is configured in a standard Type 400 mechanics circuit board arrangement. The optical signal multiplexer module therefore can be inserted into an enclosure in a direction opposite to that in which the DS1 or DS3 connector projects from the face plate, so that the DS1 or DS3 connector remains freely accessible outside of the enclosure when the optical signal multiplexer module is fully loaded into the enclosure. DS1 and DS3 cables and optical fibers can thus be easily coupled to the DS1 and DS3 and optical connectors, respectively, when the SONET multiplexer circuit is fully loaded into the enclosure.

The SONET multiplexer circuit is configured in a standard Type 400 mechanics circuit board arrangement. The SONET multiplexer module therefore can be inserted into an enclosure in a direction opposite to that in which the coaxial connector projects from the face plate, so that the coaxial connector remains freely accessible outside of the enclosure when the SONET multiplexer module is fully loaded into the enclosure. Coaxial cables and optical fibers can thus be easily coupled to the coaxial and optical connectors, respectively, when the SONET multiplexer circuit is fully loaded into the enclosure.

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.

Abstract: A compact enclosure for interchangeable SONET multiplexer cards and a method for using the same. The present invention further provides a compact enclosure for receiving one or more reduced size SONET multiplexer cards having front panel access to electrical and optical connectors, along with other cards such as DS1-DS3 multiplexer cards and wave division multiplexing cards, which is adapted for use in a reduced size enclosure, and a method for using the same.
