Abstract: A telecommunication test system for a line to be tested includes a test measurement device coupling with the line. The test measurement device determines parameter measurement data from the line. A processor receives the parameter measurement data. A first communication path between the test measurement device and the processor transmits the parameter measurement data. The first communication path is a wireless path. A mobile facility communicates with the processor. The communications are via a second communication path which includes a primary wireless path and a back-up wireline path. A central office and a data test place various signals on the line being tested. A third communication path between the mobile facility and at least one of the central office and the data test center is provided. The third communication path includes a primary wireless path and a back-up wireline path.

Abstract: Exposure or lack of adequate protection for the terminal portion of a battery against the environment is remedied by a protective `boot`, which is formed of a waterproof pliable material and is configured to fit snugly over the casing of the battery and seal the terminal portion of the battery against the surrounding environment. The battery `boot` may be molded from a rubber material or plasticized polyvinylchloride in the form of a cap portion and a sidewall portion integral with the cap portion. The sidewall portion is shaped to conform with an outer surface portion of the battery casing and is dimensioned such that, when the cover is pliably stretched so as to fit over the battery, the cap portion covers the terminals of the battery, while the sidewall portion fits tight against the battery casing and seals the outer surface portion of the battery against the entry of moisture, foreign matter and the like.
