for the TOF we have
adc(computer_id, geo_no, channel), tdc(computer_id, geo_no, channel), station, plane, slab, pmt
for the tracker we have
computer_id, geo_no, channel, tracker_no, station, plane, channel

so in python we could have a namedtuple representing the Channel_Data and a namedtuple representing the Cabling which would include a number of Channel_Data plus other bits. e.g.
Cabling(detector_name='TOF1', adc=Channel_Data(computer_id=1, geo_no=1, channel=1), tdc=Channel_Data( computer_id=1, geo_no=1, channel=2), station=2, plane=3, slab=4, pmt=5)
Cabling(detector_name='SciFi', vlsb=Channel_Data(computer_id=2, geo_no=1, channel=1), tracker_no=1, station=2, plane=3, channel=9)

the python cdb cabling api would have a number of method
get_current_cabling(detector_name)
get_cabling_for_run(detector_name, run_no)
get_cabling_for_date(detector_name, date)
these would all return the data described above

example for accessing the data
from cdb import Cabling
cabling=Cabling()
data=cabling.get_cabling_for_run('TOF1', 5)
adc=getattr(data, 'adc')
adc_channel=getattr(adc, 'channel')
station=getattr(data, 'station')
