MT8982. Therefore, to connect GCI channel B1 to
ST-BUS channel B1, the MT8982 must be
programmed to connect channel 5 to channel 2. The
five channel offset ensures that all four basic rate
channels will be switched together within one frame
period, regardless which direction the data is being
switched.
The five channel offset for GCI channels is required
even in GCI to GCI switching systems. For example,
to switch GCI channel B1 to GCI channel B2, the
MT8982 must be programmed to connect channel 5
to channel 6.
