How do I build a leased-line sync circuit?

[BMC TECH DATA BMC TECH DATA]

             I have 2 routers, 2 smart serial WIC 2A/S and 2 T1 CSU. My encoder broadcasts data to an uplink (satellite) and receives the clock from the uplink. My questions are:

What type of cables should I use, DTE or DCE?

Should I use the internal clock or try to carry the clock from the uplink to the encoder?

How do these 2 serial interfaces talk to each other? Do I use IP to route the packets?

     Thanks for any kind of help.

You need to look  at the sat. device interface and confirm its type.
