ITU-R P.341-5 FRENCH-1999 无线链路中传输损耗的概念

The ITU Radiocommunication Assembly, considering that in a radio link between a transmitter and a receiver, the ratio between the power supplied by the transmitter and the power available at the receiver input depends on several factors such as the losses in the antennas or in the transmission feed lines, the attenuation due to the propagation mechanisms, the losses due to faulty adjustment of the impedances or polarization, etc.

This ITU-T Recommendation describes a signalling interface between an International Switching Centre (ISC) and Signal Processing Network Equipment, referred to as an SPNE. This ITU-T Recommendation covers the following SPFs: echo control devices, noise reduction devices, automatic level control devices, A-law/p-law converters and frequency equalization devices. Left for further study are additional SPF types, such as PCM offset converters, etc. This interface can be supported in a facility-related manner using the Data Link (DL) of 1544 kbit/s facilities or any timeslot including timeslot O of 2048 kbit/s facilities. The interface can also be supported using a Local Area Network (LAN) or Signalling System No. 7 (SS7).This ITU-T Recommendation is specifically concerned with the transfer of signalling information on a per-call-control basis between the ISC and the SPNE, and for controlling various functions contained in the SPNE.
