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.
ADC’s Soneplex system is the lowest total cost solution for
carriers to grow their T1 business services. Focused on providing
flexible, end-to-end solutions, the Soneplex system saves carriers
money on T1-based services over fiber or copper, using HDSL,
ADSL, traditional T1 repeater or Optical DS2 technology, in a
single platform. From operations, maintenance, provisioning
and high-speed backbone connections to central office space and
cabling, the Soneplex system is designed to take costs out of
today’s T1 delivery approach, adding profit to your bottom line.
