Sent from XFIFO of SACCO-A to terminal A:
Received at RFIFO of SACCO-A from terminal A:
The connection has been established, and subscribers A and B can now
communicate.
6.1.7.2 Closing the Data Loop
With both subscribers ready at their terminals, the data loop between them can be
closed:
downstream: PCM port 0, time slot 2 to the B1 time slot of IOM-2 channel 0

6.1.7.3 Giving both Terminals the ‘Go-Ahead’ to Transceive Data
Finally, the ELIC informs both terminals that the connection has been made. This acts
as the go-ahead to pass their subscriber’s data, via the ELIC, to the other subscriber:
