You learned in Chapter 26, “Integrated Services Digital Network (ISDN),” that there are a couple
of different flavors to that technology—specifically BRI and PRI. We will discuss six different
flavors of DSL in this chapter, although there are many more. These include:
Asymmetric digital subscriber line
G.lite
High bit-rate DSL
Symmetric DSL
ISDN DSL
Very-high data rate DSL
The different flavors of DSL typically alter the bandwidth available and the range—or
distance—between the DSLAM and the end point. There can be other differences as well,
such as the need for a
splitter
to separate voice traffic from the circuit.
