necessary; use the part keyword instead. If you use the all keyword, you will find it hard to roll back to the
old version once the upgrade fails.

Overview
G. single-pair high-speed digital subscriber line (G.SHDSL) is a symmetric transmission technology that
implements high-speed data transmission over the twisted-pair copper wire by making use of the unused
high frequency ranges with different modulation methods. So far, two types of G.SHDSL are supported:
two-wire and four-wire. Two-wire G.SHDSL can provide transmission rates up to 2.312 Mbps while
four-wire G.SHDSL can provide transmission rates up to 4.624 Mbps.
The transmission speed of G.SHDSL is susceptible to transmission distance and line quality. An increased
transmission distance means decreased line quality and transmission rate, and decreased transmission
