DS2 Demultiplex Loopback
DS2 Demultiplex Loopbacks allow each of the seven demultiplexed DS2 streams
to be looped back into the MX23 and multiplexed up into the transmit DS3
stream. This overrides the tributary DS2 streams coming from the MX12s. The
DS2 loopback mode is shown diagrammatically in Figure 24 and is enabled via
the MX23 Loopback Activate register.
