The narrowband (2 – 5 kbps) digital vocoder algorithms were needed due to the limited ARPAnet link rates;  these algorithms did not run in real time, so they had to be modified and adapted to run on the new DSP systems which were just emerging.

Interoperability needed to be established among separate implementations of speech algorithms and protocols running at different sites, on different host computers and DSPs, over different types of networks, and with geographic separation across the US and between US and Europe.|a7=MIT Lincoln Laboratory conducted  pioneering R&D and experiments in packet speech, collaborating with the other organizations noted above, including USC/ISI, SRI, CHI, BBN, and others. Lincoln was a direct participant in all the milestone packet speech experiments cited above, spanning 1974-1982. In addition, in 1971, Lincoln conducted the earliest packet speech related experiments on the ARPAnet; those experiments showed the feasibility of packet speech transmission; real-time 2-way communication over the ARPAnet between Lincoln and CHI and between Lincoln and USC/ISI followed in 1974.|a8=Yes|a9=MIT Lincoln Laboratory is a secure facility.
