GM47/GM48 INTEGRATOR’S MANUAL

Connector	Description	Connections
Handset	RJ11 socket	Connector for a standard telephone
		handset. As PCM paths are open inside the
		module, a default short circuit is made
		between PCMDLD-PCMIN and PCMULD-
		PCMOUT signals on test connector J11 to
		enable analogue audio in downlink and
		uplink directions. Jumpers are in place
		between pins 48 & 50 and between pins 47
		& 49
