One of the ideals of transport networking is that paths in the transport layer would be completely transparent to the rate or format of payload applied to them. In other words, if a transport path was established from A to B, users could put any form of payload they wanted on the path without encountering technical problems such as synchronization failure or high error rates. Conceptually the ideal transport network would thus provide nothing more than "ideal wires" on demand to its service layer clients.
Thus, aside from the fact that multiple types of tributaries may be accepted as inputs, the B-DCS is functionally a pure "space-switch": signals arrive on one fiber system and are switched in space to depart on another fiber system. This simple functionality is important in the transport network backbone because it imposes the least propagation delay on signal paths and, being far simpler than cross-connects that demultiplex each signal for switching (to follow), it is also of higher availability.
The section overhead provides framing and performance monitoring for the STS-N signal and local voice "order-wire" and data communications channels. Network equipment that terminates the section overhead is called section terminating equipment (STE). This typically includes regenerators, terminal multiplexers, add/drop multiplexers and digital cross-connect systems. Regenerators are used at intermediate points along the line to extend transmission distance by converting the optical signal to the electrical domain, retiming and reshaping the STS-N signal and retransmitting it in optical form.
