[Ali. Ibra]

Hi my friends..?! Anyone know what i have to do in order for this pft optional LCOT6 card in kx-ns520 to work.
Do i have to install or setup some configuration in kx-ns500 in order for this port to work..?
In user manual they say that this port is optional LCOT6 card but i didnt know what they mean by that.

PFT is a traditional feature on all Panasonic PBXs with analog trunk.

When the power supply to the PBX fails or PBX is in a boot mode or in Off-line (upgrade mode) specific SLTs are automatically connected to specific trunks (Power
Failure Connections).
The PBX will switch from normal operation to the Power Failure Connections (it's that little click that's heard), and all
existing conversations will be disconnected.
Only the trunks handled by Power Failure Connections can be used during a power failure.
Only trunk calls can be made during a power failure. All other features do not work

Do i have to connect them to co line or to analoge ext..? As i said i try to connect this two port with analoge ext but that is does not work even in the pbx pft mode. So just if you can advise me in this point.
