Channel interface —channel-attached systems only
Your system may use a channel interface board and connector
box for channel connection to a host for IPDS printing. The
channel interface board, connected to a channel cable connector
box, handles all IPDS communications and handshaking with
PSF on the host when the NPS/IPS is receiving data over a
channel. (It is not used when the NPS/IPS is printing data using
TCP/IP.)
