Descriptions
CS-1202C is designed for communication between conference parties via standard VF channels, and also via the digital Е1 interface in digital networks.
To encode an analog voice signal, a digital channel unit with a G.703 port is used. The analog signal is A-law coded. The coded signal takes up 1 or 2 channel intervals in the E1 stream. The number of the channel interval is adjustable and can be from 1 to 31.
