Designed for use in and SNC Lyte Lynx® or Teleline Isolator*Card Shelf, the P30143 T-Carrier Isolation Card provides an isolated interface for 4-wire DS1 (such as T1) data circuits including SuperFrame, Extended SuperFrame and single or multi-channel DSO transmission, as well as any other digital channel with a primary signaling frequency in the 10kHz – 2MHz range.  Frequency response is 2kHz – 6MHz. 

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 since there is no DC path for such current though the unit.
