ENCAPSULATION PROTOCOLS
You can select from two packet encapsulation formats for Ethernet data for the Campus-REX2:
•compressed High-level Data Link Control (cHDLC)
•Point-to-Point Protocol (PPP)
The default setting is cHDLC and should be used in applications with another Campus-REX2. Use PPP only if the remote unit is a synchronous interface card, such as V.35.
When PPP is selected for bridging mode, the Campus-REX2 runs the Bridging Control Protocol (BCP) RFC 1638. PPP provides interoperability with other product types. cHDLC is a compressed version of the encapsulation protocol and is preferable when there is like equipment (ADC equipment).
