Selecting The Link Layer Protocol - Paradyne 3160-A4 Operator's Manual

Selecting the Link Layer Protocol

Two link layer protocols, Point-to-Point Protocol (PPP) and Serial Line Internet
Protocol (SLIP), are supported for connection to an external SNMP manager,
Telnet device, or network device (e.g., a router). PPP can be used for synchronous
or asynchronous operation. SLIP can be used for asynchronous operation only.
The standalone DSU/CSU implementation of PPP supports the following:

The DSU/CSU implementation of PPP does not support Link Quality Reports
(LQR), compression, encryption, Password Authentication Protocol (PAP) or
Challenge Handshake Authentication Protocol (CHAP).
The DSU/CSU implementation of SLIP supports a fixed MRU size of 1006 bytes.
Before selecting the protocol, you must first select the port to be used as the
communications link. Refer to
assumes that the COM port is being used as the communications link.

NOTE:
The carrier-mounted DSU/CSU does not support synchronous operation on
the COM port.
Full negotiation of PPP's Link Control Protocol (LCP).
Active negotiation of LCP when the connection is established.
Maximum Request Unit (MRU) sizes up to 1500 bytes, but the DSU/CSU will
attempt to negotiate down to 500 bytes.
The DSU/CSU provides a unique LCP magic number derived from the unit
serial number and the elapsed time.
Full negotiation of escape characters.
