Creating cross connections
Point to point cross connections
Three examples of point to point cross connections are shown below:
Example 1
One 2 wire DFXO interface on the near end terminal slot E port 1 is cross connected via the radio link
to a 2 wire DFXS on the far end terminal slot E port 1. This cross connection includes the four bits of
signalling (ABCD bits) but as the DFXO / DFXS signalling is configured for 'multiplexed', the four bits
are multiplexed into one bit over the radio link. 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.
The port 2s of the same DFXO / DFXS cards are cross connected using the same method.
