Reviewing The I/O Board
The I/O Board (Figure 6-3) provides both the I/O
interface from the voice channel cards to the DXP and
the RS-232 serial communication link to the computer
through a male 50-pin connector. There is lightning
surge protection built in the I/O board to protect the
DVA components.
