DCS hardware is essentially a switch. All the lines coming into a CO are connected to the DCS so the incoming digital streams can be logically connected to outgoing streams. DCSs also perform multiplexing functions, so several incoming T1s can be combined and mapped onto a single higher-speed output stream. Once the input data stream connects to the transport data stream, it can be moved across the telco network to the remote CO, as shown in Figure 2-1c. Depending on the telco’s physical infrastructure, this may happen in a variety of ways.

The CSU/DSU does not send an explicit clock for use with transmitted data, but uses internal circuitry to determine when to send a pulse.
Altering the bits is not acceptable with data transmission, so the only solution is to use one time slot for yellow-alarm prevention and to set the second bit to one.
