When the VRU port responds, the step outpulses the state code 05 to the VRU using the passing digits parameter that is included in the command. Once the VRU receives this state code, the VRU in turn outpulses the Texas VDN (3222) to Communication Manager. Thereafter, the collect digits command in step 4 collects the digits that comprise this VDN. Finally, the route-to digits command in step 5 routes the call to Texas VDN 3222, which points to vector 2.
