The DS3 interfaces transmit/receive a standard electrical DS3 signal as specified in GR-499-CORE, Section 9 (44.736 Mb/s rate, DSX-3 interconnect specification, bipolar 3-zero substitution (B3ZS) encoding). However, the signal does not have to contain a standard DS3 frame.
The E3 interfaces transmit/receive a standard electrical E3 signal as specified in ITU G.703 and G.823.
When transmitting DS3 signals to a DSX panel, the approximate span length is 450 feet.
