FAQ-Can an ISDN Phone Supply Power to Itself

Publication Date:  2015-05-06 Views:  319 Downloads:  0
Issue Description
Can an ISDN Phone Supply Power to Itself?
Solution
An ISDN phone's power can be supplied by itself or using the remote PBX. By default, no power is supplied to the AR's 2BST (BRA) board connecting to the ISDN phone. To supply power to the 2BST (BRA) board, run the remote-power command. The detailed configuration is as follows:

<Huawei> system-view
[Huawei] voice
[Huawei-voice] port bra 3/0/0
[Huawei-voice-bra3/0/0] remote-power enable
