Abstract: A device-frame for telecommunication devices includes a body-section that includes plug-in unit places for the telecommunication devices. The device-frame further includes an air-guide element movably supported to the body-section so that a flow area of an air-intake of the device-frame is increasable by changing the position of the air-guide element with respect to the body-section so that the height of the device-frame increases and the flow area is decreasable by changing the position of the air-guide element so that the height of the device-frame decreases. The height of the device-frame can be adjusted to be smaller in cases where the circumstances are not the most demanding from the viewpoint of the cooling and therefore, in less demanding circumstances, it is possible to have more device-frames in a rack.

Abstract: A satellite receiver module for telecommunication equipment includes circuitries configured to receive timing information from one or more satellites and to form timing messages based on a clock signal in accordance with the received timing information. The clock signal is a stream of temporally successive clock pulses and the pulse-rate of the clock signal is accordant with a pace indicating signal received. from a body device of the telecommunication equipment. The satellite receiver module further includes a data interface including a connector for detachably attaching to the body device and for transferring the timing messages to the body device. Because the pulse-rate, i.e. the frequency, of the clock signal is accordant with the pace indicating signal received from the body device, a high-quality local oscillator is not necessary in the satellite receiver module.

Abstract: A satellite receiver module (101) for telecommunication equipment includes circuitries (102, 103) configured to receive timing information from one or more satellites and to form timing messages based on a clock signal in accordance with the received timing information. The clock signal is a stream of temporally successive clock pulses and the pulse-rate of the clock signal is accordant with a pace indicating signal received from a body device (110) of the telecommunication equipment. The satellite receiver module further includes a data interface (105) including a connector (106) for detachably attaching to the body device and for transferring the timing messages to the body device. Because the pulse-rate, i.e. the frequency, of the clock signal is accordant with the pace indicating signal received from the body device, a high-quality local oscillator is not necessary in the satellite receiver module.
