No it doesn't.  The Cisco Pix 501 only comes with 1 ethernet port for the outside network and 4 ethernet ports for the inside network.  You could plug your router into the outside interface on the PIX if you need to use a CSU/DSU.

JFrederick29 is correct. No PIX firewall has the capability to accept a CSU/DSU module or any other serial interface.  That's what routers do...
