R2 Signalling - Signalling Variants
... R2 line signalling variants that support R2 line signalling in its electrical-pulse form by dedicated two-wire or four-wire circuits usually represent each signal as two different pulse lengths (e.g ... R2 line signalling variants that support R2 line signalling in its digital form via the A, B, C, and D bits in DS0 channel #16 of an E1 fall into two ... Those that use only the A bit, strongly resemble the analog electrical R2 line signalling, where each signal is a timed pulse that differs by length of time that the pulse is in the high voltage (i.e ...
