Mychaela N. Falconia 6e529a2c74 coding: gsm0503_tch_{fr,hr}_encode(): add ability to emit BFI ... Every BTS needs to have some graceful handling for the scenario where it is time to send out a speech frame on TCH DL, but there is no frame to be sent. One possible solution is to transmit dummy FACCH, but this option is unattractive for TCH/HS where FACCH displaces two speech frames rather than one. A more elegant solution is to emit a speech frame with inverted CRC3, causing the MS receiver to declare a BFI condition to its Rx DTX handler. Setting all u(k) bits to 0 is one way to produce such an inverted-CRC speech frame (normal TCH FR/HR CRC3 for an all-zeros frame would be 111), and this method is in fact what sysmoBTS PHY is observed to do. Add the same ability to gsm0503_tch_{fr,hr}_encode() functions, indicated by payload length of 0. Change-Id: Iade3310e16b906efb6892d28f474a0d15204e861		3 days ago
