Abstract: A cell site test tool provides field technicians with resources to support multiple aspects of cell site testing. The cell site test tool includes multiple, integrated and removably connectable modules such as a base module, a user interface module, and a battery module. Additional modules include a CPRI module to provide Common Public Radio Interface testing, an OTDR module to provide dedicated Optical Time-Domain Reflectometer testing, a CAA module to provide Cable Antenna Analysis testing, a fiber inspection module to visually inspect optical fiber, and an SA/CPRI module to provide Radio Frequency over Common Public Radio Interface testing.

Abstract: An integrated digital loop carrier (IDLC) system includes digital line feeders and signal processors to interface with the feeders an to ultimately provide data to subscriber instruments. The system can be employed as a central office terminal (COT) or remote digital terminal (RDT) with analog, T1 or SONET feeders and any conventional link medium. Data are put in DS1 format and multiplexed onto token ring optical loops for delivery to banks of channel units wherein the optical signals are translated to electrical signals for delivery to the Cus and subscribers. A method and apparatus is provided for mapping and demapping signals between virtual tributaries (VT) and digital signal formats in the RDT of an integrated digital loop carrier.
