Configuring FXS Module TDM2400P on FreePBX 13.0 server

I am running a FreePBX 13.0 for IP telephony service. The 35 extensions are working well.The system used to work perfect before it crashed and I have had to reinstall with my little knowledge on FreePBX. I have an asterisk TDM2400P FXS card with analog PSTN already set. I need assistance on configuring the ports of this card to extension Lines in order to make outbound calls and receive the calls from the external customers. Kindly assist
