The CAS multiframe may be enabled or disabled. When enabled, validation of the incoming CAS
multiframe signal in TS16 is performed. The outgoing TS16 contains a generated multiframe
incorporating idle signal codes. There is no processing of signalling data.
Individual timeslots may be selected for transmission using the DS0 selection page on the VT100
screen, however this function cannot be accessed using the front panel.
TS0 is always selected; it is either regenerated by the OM25 or passed transparently (inverted) in
both directions. It is possible to have different timeslots configured at the two ends for mixed
timeslot mapping.
