The P30128 isolation card is designed for installation in an SNC Lyte Lynx® Card Shelf or Teleline Isolator* Card Shelf. No powering is required for these passive devices. However, if a span powering is required to operate the remote HDSL unit, the station side of the P30128 data card should be powered by the desired voltage.
These data isolation models provide an isolated interface for 4-wire digital or analog data circuits while providing span power toward the customer equipment. Types of digital circuits protected include rates of 2.4 kbps to 72 kbps as used in services such as Synchronet, Basic Rate ISDN and HDSL carrier frequencies. Types of analog circuits protected include rates of 100 Hz to 200 kHz as used in analog carrier, modems, SCADA, tone relay control and tone signaling.
The primary function of the card is to provide isolation from hazardous voltages while being “transparent” in the circuit. All signaling information within the specified frequency bandwidth will be unaffected. However, DC signaling is not supported. A secondary function is to provide connections for the loop back of DC simplexed sealing current or repeater powering on the remote (Central Office) side. DC path for such current through the unit is provided.
