Modem tone telegraphic is designed for use as a device that provides the ability to organise exchange over telegraphic channels, compacted in channel intervals of digital stream E1 (G.703) or in the channels THF (0,3 -3,4 kHz).
When connecting a digital stream, counter and transit switching is provided.
Setting of MTT functioning parameters is carried out by software.
During the setting is set:
- number of used channel intervals of E1 digital stream or PM channels (up to two);
- numbers of the involved channel intervals of the E1 digital stream;
- the number of telegraph channels in each channel interval of the E1 or PM stream (from 1 to 24);
- information transmission speed;
- operation mode (control by the TLG equipment server or autonomous).
All telegraph channels compacted in channel intervals of E1 or PM stream are served by means of one Ethernet port.
