The iPSU itself requires no regular maintenance; however, the battery inside the iPSU
requires periodic replacement. See "Replacing the battery" on page 35 for
instructions to replace the backup battery.
Note: The battery provides power for voice services during a power outage.
Subscribers are responsible for monitoring and replacing the battery when needed.
The service provider does not monitor the battery and is not responsible for its
replacement.
i38HG (inside unit)
The i38HG is the unit that goes inside the subscriber's home and can be installed by
the subscriber or by the service provider. Working together with the i3822V, the i38HG
is a home networking hub that provides an 802.11b/g Wi-Fi access point and Ethernet
switch functions for connecting personal computers and other in-home networked
devices to the service provider's network. The i38HG has four Ethernet ports for
directly connecting computers or devices.
The i38HG includes an integrated wireless access point to provide wireless
connectivity throughout the home or office. High-powered wireless technology virtually
eliminates wireless "coldspots" in the home. The i38HG high-power 400mW
transmitter ensures that you benefit from increased wireless bandwidth throughout the
coverage area. In addition, the i38HG employs a special triple antenna design. The
third antenna is used only for transmitting packets, thus mitigating the power loss
associated with switching the antenna use back and forth between transmit and
receive. This results in greater access point sensitivity, as antenna placement can be
better optimized with a dedicated set of receive-only antennas.
To expand the wireless coverage in a home or add additional Ethernet ports in
different locations in the home, you can connect multiple i38HG devices to different in-
home phone jacks. Each i38HG is automatically configured to operate on the same
wireless network, and the devices can be centrally configured and managed at
