Example 2
One 2 wire DFXS interface on the near end terminal slot E port 1 is cross connected via the radio link to a
framed E1 on the far end terminal slot D port 1 in timeslot 1. This cross connection includes four bits of
signalling as the DFXS signalling is configured as 'non-multiplexed signalling' (ABCD bits). This cross
connection uses 96 kbit/s of radio link capacity, 64 kbit/s for the voice and 32 kbit/s for the signalling
bits.
Another 2 wire DFXS interface on the near end terminal slot F port 1 is cross connected via the radio link
to a framed E1 on the far end terminal slot D port 1 in timeslot 2. This cross connection includes one bit of
signalling as the DFXS signalling is configured in '4 wire compatible' mode (A bit only). This cross
connection uses 40 kbit/s of radio link capacity, 32 kbit/s for the ADPCM voice and 8 kbit/s for the
signalling bit.
Example 3
One 2 wire DFXS interface on the near end terminal slot E port 1 is cross connected via the radio link to a
framed E1 on the far end terminal slot D port 1 in timeslot 1. This cross connection includes one bit of
signalling as the DFXS signalling is configured as 'multiplexed' signalling. This cross connection uses
72 kbit/s of radio link capacity, 64 kbit/s for the voice and 8 kbit/s for the signalling bit.
