Title:
FRAME INFORMATION TRANSFER METHOD
Document Type and Number:
Japanese Patent JPH01155733
Kind Code:
A
Abstract:
PURPOSE:To prevent missed frame probability from depending on a mark rate by allocating a mark to bits proceeding by a specific bit number from a code rule violation bit normally. CONSTITUTION:The period of frame structure is 125musec, the speed is 2.048Mb/s and each frame consists of 32 times slots(TS). Each TS is 8 bits and the slots from TS2 to TS16 and from TS18 to TS32 are assigned for data and the TS 17 is idle. The bit of 2 of TS 1 is a CRV for the mark and the mark is allocated to bit 1 of the TS1 just before. A first case 1 where the CRV is missing is the occurrence of an error in the bit 2 of the TS1 subjected to CRV and a second case 2 is where bit 1 of the TS 1 has an error, then the CRV missing probability and misframe probability are constant independently of the mark rate.
