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).
