PPP can be used forsynchronous or asynchronous operation. SLIP can be usedfor asynchronous operation only.NOTEThe carrier-mounted CSU doesnot support synchronousoperation on the COM port.The standalone CSU implementation of PPP supportsthe following:• Full negotiation of PPP’s Link Control Protocol(LCP).• Active negotiation of LCP when the connection isestablished.• Maximum Request Unit (MRU) sizes up to1500 bytes, but the CSU will attempt to negotiatedown to 500 bytes.• The CSU provides a unique LCP magic numberderived from the unit serial number and the elapsedtime.• Full negotiation of escape characters.The CSU implementation of PPP does not supportLink Quality Reports (LQR), compression, encryption,Password Authentication Protocol (PAP) or ChallengeHandshake Authentication Protocol (CHAP).The CSU implementation of SLIP supports a fixedMRU size of 1006 bytes.Before selecting the protocol, you must first select theport to be used as the communications link. Refer to theSelecting the Port section on page 3-11. This exampleassumes that the COM port is being used as thecommunications link.
