eCall data transfer; In-band modem solution; ANSI-C reference code
The present document contains an electronic copy of the ANSI‑C code for the eCall in-band modem solution for reliable transmission of MSD data from IVS to PSAP via the speech channel of cellular networks. The ANSI‑C code is necessary for a bit exact implementation of the IVS modem and PSAP modem described in 3GPP TS 26.267 [1].
