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.
