P30050 4-Wire HDSL/56kbs Data Isolation Cards

  • P30050 4-Wire HDSL/56kbs Data Isolation Cards

P30050 printed circuit boards are designed for installation in an SNC Lyte Lynx® Card Shelf or Teleline Isolator* Card Shelf. No powering is required for this passive device.

This data isolation model provides an isolated interface for 4-wire (P30050) data circuits. Types of data circuits protected include Synchronet services and digital data services operating at 72k bits per second (bps) and sub-rates (including 72, 64, 56, 25.6, 19.2, 12.8, 9.6, 6.4, 4.8, 3.2 and 2.4 kbps), basic rate ISDN, HDSL, analog signals for data modems, SCADA, tone relay control, analog carrier, and tone signaling up to 100 kHz.

The primary function of the card is to provide an 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 for the loopback of DC simplexed sealing current/repeater powering current on the remote (Central Office) side of the units, since there is no DC path for such current through the unit. This data isolation interface model is a passive, magnetic-coupled device. Primary to secondary isolation is rated at 65kV BIL.

This unit is factory tested with HDSL termination equipment.

See the 56kbs/HDSL Transformer Insertion Loss Graph and Performance Specifications Table.
