The Patton 4960 allows you to connect 3CX to T1 or PRI depending on the model you get. It can have one to four ports. Following is the image of a Patton 4960 unit with four PRI ports and two Ethernet ports:
The Patton 4960 configures exactly like Patton 4114. The user interface and steps to import the 3CX configuration file are identical, so we can use the steps mentioned previously in the Configuring the Patton 4114 FXO gateway section to import the 3CX configuration file.
The one you have to watch out for is related to the Ethernet ports on two port models. When the Patton gateway ships, new port 0/0 will be a DHCP client and port 0/1 will be a DHCP server, so you will want to plug into port 0/0. The tricky thing is after the gateway has been configured, data will be routed to port 0/1, so you will need to switch this after the unit has been configured by the 3CX configuration file.
