Verification of the transmission integrity of a complex, broadband network such as the L5 Coaxial-Carrier Transmission System requires many measurements at different locations and considerable proc
It is the goal of the Bell System to maintain frequency offset in any transcontinental circuit to within ±2 Hz.
While gross performance objectives for analog multiplex equipment are available, the detailed statement of design objectives is part of the development task.
The repeaters and equalizers in the L5 coaxial-carrier transmission system are spaced at approximately one-mile intervals along the cable system.

During the last 30 years, long-haul transmission facilities have been rapidly expanded to meet the increasing need for both voice and data transmission, and it is expected that rapid growth will co

The basic function of the L5 repeatered line is to provide a lossless transmission facility between any two L5 terminal stations, which may be located as far as 4000 miles (6400 kilometers) apart,
At the beginning of the Lo project in 1968, the set of computeraided design (CAD) tools and the specialized computer-operated transmission measurement set (COTMS) at the Merrimack Valley location o
The L5 coaxial line is a transmission facility with a message capacity of three jumbogroups. These jumbogroups are placed on the line in the frequency format shown in Fig, 1.
