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.
