Two-Pair T1 Fixed-Rate HDSL

WorldDSL™ Two-Pair T1 Fixed-Rate HDSL WorldDSL is ADC’s line of high-speed HDSL access devices specifically designed for the diverse telecommunications needs of global markets. Ideal for telco and enterprise networks, WorldDSL products comply with international standards to ensure compatibility, performance and safety within your network environment. The LTU-/NTU-814s are the latest WorldDSL products that provide two-pair T1 fixed rate HDSL and can be installed at the CO or the customer premises. The LTU-/NTU-814s can be part of a fully managed system. Using a VT100 compatible terminal or a PC, they can be managed via their local craft ports or centrally via a management card installed in a CO shelf. The user may also select ADC`s SNMP management software running under Windows to provision the system, collect alarm and performance data, and conduct diagnostic tests either locally or from a remote management station. In any of these modes, both ends of the circuit can be programmed and managed through the CO, minimizing travel to the customer site.
