4TEL®
Automated Copper Loop Testing for Broadband and Voice Services Support
The 4TEL system includes a compact measurement head – the Loop Diagnostic Unit (LDU) 100. The LDU 100 is installed in any host or remote exchange. This single test head, deployed throughout the network, provides the necessary capabilities to support on-demand, reactive testing as well as pro-active routining for early trouble identification or bulk qualification.
The LDU 100 accesses each copper loop via the test access facilities of the switch or through a Test Access Matrix (TAM). Each LDU 100 is capable of performing the necessary measurements to support broadband deployment and service assurance as well as traditional voice service assurance.
In addition to the LDU 100, the 4TEL system includes the Test System Controller (TSC). The TSC is an industry standard computing platform that provides the human and machine interfaces for the service provider’s support personnel and Operations Support Systems (OSS).
Each TSC supports testing and results analysis and archival for up to one million assigned lines. For larger networks, multiple TSCs seamlessly network together for total test coverage of even the largest provider’s copper plant.
Testing throughput can be optimized by utilizing multiple LDUs within the same exchange. This allows multiple, simultaneous demand tests to be performed, reducing or eliminating test blockage in larger exchanges and also decreasing the time required to routine the entire exchange for broadband qualification or pro-active trouble identification.
