The DS1 Loop Extender (DLX) module is used to extend a DS1 up to 655 feet to a digital cross-connect (DSX-1). The DLX receives a non-return to zero (NRZ) 1.544 Mbps signal from the DS3 Soneplex multiplexer module, converts the NRZ signal to a bipolar DS1 signal and transmits a DS1 signal that meets the industry standard DSX-1 template boundaries as defined by TR- NWT-000499.
