19.6.1ME status indicated by status LED patterns

The following table lists the possible patterns of status LED behavior, and describes the ME operating status indi- cated by each pattern if AT^SSYNC parameter <mode>=1 and <mode>=2.

Table 19.1: Modes of the LED and indicated ME functions

	LED behavior	ME operating status if AT^SSYNC=1	ME operating status if AT^SSYNC=2
	Permanently off	ME is in one of the following modes:	ME is in one of the following modes:
