- 适用范围
- 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.
