HDSLx/T1Today's HDSLx technology includes HDSL, HDSL2, and HDSL4 with each technology developed to meet specific, carrier needs. ADTRAN has been a leader in standards development for HDSL2 and HDSL4 technologies by closely working with standards committees. HDSL2 and HDSL4 technologies have largely replaced T1 and HDSL (2B1Q), providing pair savings (with HDSL2) and DSL spectral compatibility. HDSL4 using four wires (two pairs) and up to three repeaters extends carrier reach beyond the Carrier Serving Area (CSA). T-Scan is a feature developed by ADTRAN for HDSLx circuits that provides the user with remote management and fault isolation capabilities. T-Scan allows provisioning, performance, and event history information to be retrieved by the test center via the Facility Data Link (FDL). In addition, Tscan can be used to determine the nature and location of faults on DS1 trouble circuits.
ADTRAN HTU-Cs work in conjunction with ADTRAN HTU-Rs and ADTRAN
HREs to provide a DS1 service up to 36,000 feet on the local
loop.
The ADTRAN HDSL System Shelves are designed for use in
applications where it is beneficial to replace a series of T1 repeaters
with HDSL transceiver technology.
ADTRAN HDSLx/T1 NTUs are network terminating units using High-bit-rate Digital Subscriber Line (HDSL) technology to transport T1/E1 data over copper loops.
ADTRAN's HDSLx/T1- Range Extenders (HRE) can effectively double the deployment range of standard HDSL and provide Carrier Service Area (CSA) -compliant loops on both sides of the HRE.
The Total Access 3000 Chassis can be used to provide a variety
of digital services, including HDSL, HDSL2, HDSL4.
ADTRAN Total Access 3000 Hi-Cap Central Office Bays and Total Access 3000 Fiber Ring Cabinets (FRC) are designed to provide cost-effective HDSL, HDSL2, HDSL4 services.
The Total Access 5000 Chassis can be utilized in conjunction with the Total Access 1500, Total Access 3000 and OPTI-6100 to provide a variety of digital services.
