2.3.5 CAS/SS7 signalling DSP module LEDs
Each signalling DSP has three LEDs to indicate status. The green LED will remain off
until the module is taken out of a reset state. When two DSPs are present, these two
LEDs will flash alternatively to indicate the module is not in a reset state.
The remaining red and green LED pairs are under DSP software control.
