08.063GPPRelease 1999Signalling transport mechanism Specification for the Base Station System - Mobile Services Switching Centre (BSS - MSC) interfaceTS

The present document is split into two parts, clause 1-4 dealing with the MTP and clauses 5-7 dealing with the SCCP and its use.

The MTP provides a mechanism giving reliable transfer of signalling messages. Clauses 1-4 of the present document deal with the subset of the MTP that can be used between an BSS and an MSC, which is compatible with a full MTP.

The SCCP is used to provide a referencing mechanism to identify a particular transaction relating to for instance a particular call. Clauses 5-7 identify the SCCP subset that should be used between a BSS and an MSC. The SCCP can also be used to enhance the message routing for (for instance) operations and maintenance information.

0.3 Definitions

E1 link employs 32 Pulse Code Modulation signals (timeslots) at 64 kbits/s. The 32 timeslots consist of 30 voice (or signalling) channels and 2 common signalling channels. The output bit rate is 2 048 Mbits/s.

T1 link employs 24 Pulse Code Modulation signals (timeslots) at 64 kbits/s. (T1 interface can alternatively use signalling at 56 kbits/s). The output bit rate is 1 544 Mbits/s. (A frame consists of 193 bits, (8 * 24) + 1, as one bit is used for synchronization. The frame repeats 8,000 times per second.).
