The CPE provides an ADSL uplink port connecting to WAN. For
data services, subscribers can access Internet via WLAN or
Ethernet interface. For voice services, the device supports both
VoIP and PSTN calls. These two services will finally go to
softswitch network and Internet separately. VoIP is the
preferred telephony service for users as it offers a lower call
charge than PSTN. However, PSTN service is supported for
complement of VoIP service when PSTN is the designated call
path, VoIP service is not available, or during a power outage of
the device.
