Newtec Azimuth AZ120 G.703 E1 Telco Satellite Modulator
Supports E1 rates up to DS3 (T3)
AZ120 G.703 Telco Modulator
This product has reached end of life and has been replaced by the Newtec M6100.
The Newtec AZ120 is a state-of-the-art satellite modulator designed for fi xed-rate telco voice and data applications over satellite in full compliance with the DVB standards. The AZ120 can be used in conjunction with the telco satellite demodulator AZ920. The AZ120 interfaces directly with terrestrial data and voice networks through a standard G.703 interface.
E1 Data Rates
In its default configuration, the AZ120 supports E1 rates. The support of E2, T2, E3 and T3(DS3) rates are available as configuration option. It is also possible to confi gure the modulator with a secondary G.703 input, for the implementation of a redundant configuration or to allow the modulator to be compatible with two different transmission rates. At the output of the modulator, the signal is available on an L-band interface. IF- and RF-band as well as BUC power supply and reference frequency are available as configuration options, providing a compact and cost effective solution.
DVB-S2
This modulator is fully compliant with the DVB-S and DVB-S2 standards and provides exceptional performance and bandwidth effi ciency. When activated, the unique linear and non- linear predistortion option Equalink provides an additional link margin improvement of up to 2,5dB, truly unleashing the full effi ciency of higher modulation schemes such as 16 and 32 APSK.
