Technical Specifications

The analog DC loop trunks (i.e., FXO ports) can detect line DC feed, polarity reversal, and 12 or 16 kHz charge pulses and are capable of receiving Caller ID information transmitted according to the ETSI ETS 300 659-1 standard as an FSK signal burst. Overvoltage and overcurrent protection on analog trunks conforms to ITU-T K.20/K.21 recommendations. Additional primary protection devices to those residing in the main distribution frame may also be employed for further protection.
