Designed for use in and SNC Lyte Lynx® or Teleline Isolator*Card Shelf, the P30140 Isolation Card provides 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 bandwith will be unaffected.  However, DC signaling is not supported.  A secondary function is to provide termination for the loopback of DC simplexed sealing current or repeater powering on the remote (Central Office) side.  A DC path for such current though the unit is also provided.
