Abstract: PURPOSE: A method for assigning channels is provided to examine a local trunk interface(LTRI) performing link accesses between a remote switching module(RSM) and a host exchange station to assign the channels, only when the LTRI is in an activated status so that the RSM can receive digits from subscribers in an independently-operated status. CONSTITUTION: If an optional subscriber is hooked off to perform a call, a remote switching module(RSM) processor senses an off-hook state. The processor identifies whether a dual tone multi frequency(DTMF) signal corresponding to a called telephone number is capable of being received. The processor examines a link status with a host exchange station. The processor examines whether the link status is normal. If so, the processor performs a normal call processing routine and returns. If the link status is not normal because of a cable rupture or a link communication error, the processor converts a status of an RSM into an independently-operated status. The processor retrieves an internal memory to read an alarm register. The processor reads a local trunk interface(LTRI) number presenting an activated LTRI. The processor examines whether a DTMF signal is received from the subscriber. If so, the processor assigns a channel designated in the LTRI on the basis of the LTRI number, and switches the channel, then returns.

Abstract: PURPOSE: Provided is an agitator for use in wastewater treatment plant and/or water purification plant. The mixing device is characterized in that each paddle installed at the upper and lower part of the axis of rotation is revolved in different speed. CONSTITUTION: When the axis of rotation is revolved by a drive device, the upper axis of rotation(3a) and the lower axis of rotation(3b) are revolved in different speed by a rotation speed changer gear(6). In the rotation speed changer gear(6), a diameter of a gear(10b) installed at the lower axis(3b) is different from a diameter of a gear(9b) installed at the side axis(8), so, rate of the upper axis of rotation(3a) is different from the lower axis of rotation(3b). Therefore, each of the upper paddle and the lower paddle is revolved in different speed. The upper paddle is revolved in the proper rate for mixing, and the lower paddle is revolved in the flotation limit rate. Consequently, mixing efficiency is maximized.
