This chapter includes the commands for configuring Point-to-Point Protocol (PPP) 
encapsulation on a T1 or E1 interface or a Serial Interface (V.35/X.21). You are

the PPP commands and descriptions on each of their parameters, refer to the 
OmniAccess 5740 Unified Services Gateway CLI Command Reference 
Guide.
