| Summary | This standard specifies the function with ISDN switch LT "U" interface to the user side of the power supply configuration, supply power, output voltage, output current, the protection threshold and the associated detection methods. This standard applies to ISDN function switches and their associated NT1, NT1 + other network terminal equipment, ISDN terminal equipment and the need for the network side (CO) Far-powered basic rate digital transmission systems. This standard can also be used as an ISDN metallic local line power requirements of digital transmission systems away basis. This standard specifies the parameters is based on the power supply line of the user's system, but does not intervene in the discharge during the application of regenerative repeater mode. For the powered device or system for self-switch LT "U" interface to obtain the distribution of power usage values ??not specified in this standard. |
