An improved DDR interface uses single-ended technology and phase-shifts all output data signals and the output source clock signal so that each output signal switches at a different time so that IDDQ spikes caused by I/O switching do not accumulate. A dynamic phase adjustment circuit on the receiver compensates for the phase differences. Clock jitter and skew is reduced and the number of IDDQ pins is reduced to provide a more effective design and high density package.

Network data is received in a first format. The data is converted to a synchronous optical network (SONET) format. Switching functions are performed on the SONET formatted data. The SONET formatted data is converted to a second format. In one embodiment, the switching functions on the SONET formatted data contains performing time switching and space switching.

The invention provides a special telephone set for a hotel. The special telephone set for the hotel comprise a fixed-line telephone and a power source thereof, wherein the fixed-line telephone is connected with a second-level dial disc and a second-level receiver; the special telephone set for the hotel further comprise a monitoring unit installed in the fixed-line telephone; the second-level dial disc and the second-level receiver are connected with the fixed-line telephone through a switch; and the monitoring unit is connected with a switch 1. Compared with the prior art, the second-level dial disc, the second-level receiver and the monitoring unit are adopted, and therefore, the service life of the telephone set can be prolonged, and the use distance of the telephone set can be increased, and the use range of the telephone set can be extended; a camera, spring wires, the timing switch and an LED light are adopted, and therefore, visual monitoring can be realized, use cost can be decreased to the greatest extent, an economical timed switching on function can be realized, and telephone dialing at night can be facilitated; and the telephone set is simple in overall structure and has high practicability.
