Abstract: Embodiments of the invention provide a system for supporting numerous multiplexed and demultiplexed T1 signals and additional Ethernet signals between two DS-3 signals. In an embodiment, the multiplexer device is housed within a single rack unit on a standard 19? or 23? rack. In a further embodiment, all T1, Ethernet, alarm driver, and power connections are made from the front of the multiplexer unit, allowing easier access to the device connections restricted spaces. In a further embodiment, the system provides redundancy for the T3, T1, and Ethernet circuits, allowing error remediation. The system may also allow error detection for the associated telecommunications network.

Abstract: An electronic component, particularly a multiplexer, having a housing that is configured to consume less space when stored in a vertical electronics rack is provided. The housing generally includes a rear end having a plurality of connectors and a front end, a bottom wall, a pair of laterally spaced side walls and a top wall. The top wall is configured such that a portion of the housing at the rear end of the multiplexer has a relatively larger height than the remainder of the housing.
