G.SHDSL High Speed WICs (HWICs)
The G.SHDSL high speed WICs (HWICs) are available in the following variations:
•
The G.SHDSL HWICs support up to four pairs of DSL: two inverse multiplexing over ATM (IMA)
lines, and two ATM segmentation and reassembly (SAR) lines. The four DSL pairs are bundled in
groups and configured in the Cisco IOS command-line interface (CLI) by using the
dsl-group
command.
–
The HWIC-2SHDSL provides two ports of connectivity through one
RJ-11
connector. It
supports
1-Pair
groups or
2-Pair
groups.
–
The HWIC-4SHDSL provides four ports of connectivity through one
RJ-45
connector. It
combines four ports 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.
LEDs on G.SHDSL HWICs
The G.SHDSL HWICs have 4 LEDs that indicate DSL functionality.
