Assembling and Cabling the
WAN Components
The CCNP Remote Access Exam requires you to have an in-depth understanding of various
WAN technologies. This chapter focuses on the cabling requirements of various
technologies.
Although individual WAN topologies can require specific cabling variances and Frame
Relay implementations require little or no variance from implementations of High-Level
Data Link Control (HDLC), the physical cabling is virtually identical. However, other
technologies can have different requirements depending on the location (internal or
external) of WAN devices, such as CSU/DSU's or NT1's.
This chapter explores the basics behind racking and cabling the remote access devices
discussed in this book. The discussion in this chapter focuses on routers.
