Overview
The V5 interface is the interface between an access network and a host exchange for the support of narrowband telecommunications services. It has two forms, V5.1 and V5.2, and the more sophisticated V5.2 form supports the concentration of traffic. The apparent complexity of the V5 interface is a result of meeting a number of simple basic requirements, and the avoidance of unnecessary functionality has been a driving consideration. One consequence of this is that in-band tones are passed transparently across the V5 interface and the responsibility for their generation and detection remains with the host exchange, not the access network.
In this chapter the architectural model associated with the V5 interface is described, together with the physical structure of the interfaces and the services they support. Subsequent chapters describe the general multiplexing and format of V5 messages, the multiplexing and handling of...
