The TD 790 Teleco system is used for the conditioning of the data transmission circuits both in voice band (300Hz ÷ 3400Hz) and in base band (200Hz ÷ 40KHz).

ATTACHMENTS

The TD 790 Teleco system is used for the conditioning of the data transmission circuits both in voice band and in base band and it is realized on normalized N2C rack.

The TD 790 system allows the recovery of the losses that show them in the data transmission circuits, through the following performances:
– Level adaptation from -10 to +13,5 dB (amplification of the attenuation).
– Phase equalization up to 3 ms.
– Amplitude equalization for lines up to 16 dB to 3400 Hz – 18 dB to 40 KHz.
– Realization of particular circuit configurations required in the exchange for data transmission (multipoint structure).

The two base devices that constitute the fundamental elements of the TD 790 system are:
MU 790 Conditioning device for circuits in voice band (300 ÷ 3400 Hz).
MB 792 Conditioning device for circuits in basic band (200 Hz ÷ 40 KHz or circuits for numeral frequencies up to 19,2 Kbit/s).

The two devices allow the complete and separate conditioning of the two lines of connection to them attested and they are suitable both to the user connections and of junction.
