NEC NDA-24298 manual SMDR2

ARTD : Assignment of Route Class Data

	b3		b2		b1		b0
										0/1: -/Incoming Call (SMDR is required)
									0/1: SMDR is required for toll and local out-
									going calls/SMDR is required only for toll
									outgoing calls.
				0:				Metering pulses are necessary. Hexadecimal
				1:
								assignment is “01.”
				2:
				3:
Example:
b3		b2		b1		b0
0		0		0		1					b0=bit 0
											b1=bit 1...
8		4		2		1

The following explains what hexadecimal data “1” means for SMDR2:

• For incoming calls SMDR is required because Bit 0 is assigned as one (1).

• SMDR is required for toll and local outgoing calls because Bit 1 is assigned as zero (0).

• Metering pulses are detected by the system; therefore Bit 2 is zero (0) and Bit 3 is zero (0).
