Fixed Subscriber Unit Installation Manual General Description 2-3 2. General Description The Fixed Subscriber Unit (FSU) is the radio equipment that connects to fixed standard telephones and is located in the subscriber’s residence. FSUs consist of a Radio Frequency (RF) interface and a telephone line interface. Together they manage the supplied line voltage, the ringing signal, Dial Tone (DT) and Busy Tone (BT) to the telephone, detect off-hook and on-hook states, and dialing.
2-4 General Description Fixed Subscriber Unit Installation Manual authentication, hooking signal transmission, and meter pulsing signal transmission functions are provided. 2.1 Outgoing calls The call handling procedure for an outgoing call is depicted in Figure 2-2 and is described following the figure. A terminal on an FSU sends dialing information with standard in-band DTMF tones after recognizing dial tone. 5 CO Switch MDF 4 COT RPC 3 RP 1 2 MDF FSU RP 3 Figure 2-2 : Outgoing Call 1.
Fixed Subscriber Unit Installation Manual General Description 2-5 3. The RP resends the received message to the Radio Port Controller (RPC) through the twisted pair wires via the Main Distribution Frame (MDF). 4. The RPC converts the PHS protocol message to a Q.931 protocol message. In addition, the RPC extracts the dial code from the outgoing message, and changes it to DTMF signals. The Q.931 message is sent to the COT through the D-channel of the E1 line. 5.
2-6 General Description Fixed Subscriber Unit Installation Manual 1. A specific analog line is rung in the CO. The signal is sent to the COT via the MDF. 2. The COT detects the ringing of the line and sends the incoming message with the Q.931 calling number to the RPC. 3. When the RPC receives the incoming message from the COT, the RPC converts that Q.931 message to the PHS incoming message protocol and sends it through the MDF to all of the RPs. 4. The RPs page all FSUs and PSs.
