Important! The default byte values correlate to AB bits for signaling. The AB bits are two discrete binary values, but the EXS API uses a hexadecimal representation. For received line signaling, only AB bits are validated. You must use custom PPLs to comply with T1.403-1995/ANSI T1.403.02-1999 for received line signaling. To change default Out of Service signaling, use the PPL Transmit Configure message. Changes to configuration bytes will change transmitted signaling only when In Service.
