. The default is
A
UTO
. Selecting
A
UTO
enables the Auto-config feature. Reference DLP-014, Unit Installation Using The Auto-Config Feature ,

Point-to-Point Protocol (PPP) is an 8-bit serial protocol which allows a PC to connect as a TCP/IP host to a
network through an asynchronous port. PPP is used for connection from a PC to an Internet Service
Provider (ISP) for Internet access. PPP works over synchronous and asynchronous circuits.
Router-to-router and host-to-network connections can be made via PPP. PPP includes error detection while
Serial Line Internet Protocol (SLIP) and other protocols do not.

Frame Relay is a switched data link layer protocol that handles multiple virtual circuits using High-Level
Data Link Control (HDLC) encapsulation. Frame Relay uses statistical multiplexing as opposed to
time-division-multiplexing to multiplex many logical connections over a single physical link. It contains a
cyclic redundancy check (CRC) for detecting bad data, but leaves the error correction algorithms to be
performed by the higher protocol layers. Similarly, Frame Relay uses simple congestion notification. This
notification in turn can alert higher-layer protocols to exercise flow control. These characteristics allow
Frame Relay to provide a more flexible and efficient use of bandwidth.

to
A
UTO
allows the unit to automatically detect the
L2 P
