Cisco G.SHDSL HWICs
Cisco G.SHDSL HWICs are available in two variations:
• The Cisco HWIC-2SHDSL (Figure 1) provides two lines of connectivity through one RJ-11
connector. It supports 1-Pair groups or 2-Pair groups.
Figure 1 Cisco HWIC-2SHDSL Faceplate
• The Cisco HWIC-4SHDSL (Figure 2) provides four lines of connectivity through one RJ-45
connector. It combines four lines of data into one line or two lines with either inverse multiplexing
over ATM (IMA) groups or M-pair groups, and it supports 1-Pair groups or 2-Pair groups.

Note The Cisco HWIC-2SHDSL provides support for the Dying Gasp feature; however, the
Cisco HWIC-4SHDSL does not provide support for this feature. The term dying gasp refers to power
status as defined in ITU-T standard G.991.2, section 7.1.2.5.3.
