ADC Campus-REX RS Interface Card ENCAPSULATION PROTOCOLS

Internetworking and Management Overview

ENCAPSULATION PROTOCOLS

You can select from two packet encapsulation formats for Ethernet data for the Campus-REX:

•High-level Data Link Control (HDLC)

•Point-to-Point Protocol (PPP)

HDLC is the default setting, and should be used in most applications. Use PPP only if the remote unit is a synchronous interface card, such as V.35.

When PPP is selected from bridging mode, the Campus-REX runs the Bridging Control Protocol (BCP) RFC 1638. PPP provides interoperability with other product types. HDLC is a compressed version of the encapsulation protocol and is preferable when there is like equipment.
