1. A wellbore servicing tool, the wellbore servicing tool comprising:

  • a housing comprising one or more ports and a flow channel;

    triggering the system;

    a first sliding sleeve slidably positioned within the housing and transitioning from a first position of the first sliding sleeve to a second position of the first sliding sleeve; and

    a second sliding sleeve slidably positioned within the housing and transitioning from a first position of the second sliding sleeve to a second position of the second sliding sleeve;

    wherein when the first sliding sleeve is in the first position of the first sliding sleeve, the first sliding sleeve retains the second sliding sleeve in the first position of the second sliding sleeve, and when the first sliding sleeve is in the second position of the first sliding sleeve, the first sliding sleeve does not retain the second sliding sleeve in the first position of the second sliding sleeve,wherein when the second sliding sleeve is in its first position, the second sliding sleeve prevents a fluid communication path through the one or more ports of the housing, and when the second sliding sleeve is in its second position, the second sliding sleeve allows fluid communication through the one or more ports of the housing, andwherein the triggering system is configured to;

    in response to identifying a predetermined signal, wherein the predetermined signal comprises a predetermined pressure signal comprising one of;

    a pulsed telemetry signal, a series of discrete pressure thresholds over multiple time samples, a series of ramp pressures over time, a pulse width modulated signal;

    wherein the trigger system comprises a pressure sensor, an electrical circuit, and an actuating member;

    wherein the second sliding sleeve further comprises a flapper valve, wherein the flapper valve is retained by the first sliding sleeve when the first sliding sleeve is in the first position of the first sliding sleeve, and wherein the flapper valve is not retained by the first sliding sleeve when the first sliding sleeve is in the second position of the second sliding sleeve;

    wherein the second sliding sleeve is configured to;

    the second sliding sleeve moves from a first position of the second sliding sleeve to a second position of the second sliding sleeve upon application of a force to the second sliding sleeve by the flapper valve.
