It would probably be conecting to a Prima CDQ or other such device:

Usually this would be over 2 B channels at 128kbs MP2.

64kBs is normally OK for news, 128kbs should be OK for normal talking, but
will be well shy of the quality required for music (CD = ~700kbps), although
it compresses well e.g. MP3.
