To further facilitate device connectivity to the PsipTN, TelTel offers a ready made box called the Keystone Base Station or KBS which pre-embeds and pre-configures Keystone software module onto the KBS unit for seamless connection to the PsipTN network. Traditional and new generation consumer electronics devices can readily connect to the PsipTN through KBS via a host of RF and other wireless standards without having to go through the Keystone software development and integration cycle. Equipped with up to 4 USB ports on a KBS unit, KBS provides universal connectivity with virtually any consumer electronics devices in a digital home to allow such connected devices to be attached to the PsipTN with no development or integration effort.

From the end user's point of view, a user treats each of the USB ports on a KBS as a universal access point into the PsipTN network. Similar to how a USB device can be plugged into a computer which identifies the device and downloads if necessary the device driver automatically, a KBS offers the end user PsipTN plug-and-play capability of any consumer electronics devices which can be connected to the KBS via either a standard USB connector or any of the wireless standards supported by the KBS. KBS will automatically download from the PsipTN plug-in’s necessary to support devices connected to the KBS. The end result is a realization of a global USB network powered by the PsipTN where virtually any consumer electronics devices can interconnect and interoperate in the PsipTN based network computing cloud.
KBS is available in 3 models (KBS Lite, KBS Classic, KBS Plus) based on its ability to handle media traffic.
