A2.3.2

Digital AES/EBU Audio interface

The b-line XT Telephone Hybrid incorporates two digital Inputs/Outputs
which are physically one AES/EBU interface. The input has a digital sample
rate converter providing that a digital source with 32, 44.1 or 48-kHz can be
connected directly. For external clocking (48-kHz only) the word clock input
or output may be used.
