Interface S0 0 0 Dce
DCE stand for Data Circuit-Terminating Equipment. It is locate at end of the WAN provider side of communication facility. DCE provide clock signal which known as internal clocking. Example DCE device is modem.
DTE stand for Data Terminal Equipment. It is user device with interface connecting to the WAN link. DTE synchronized provided clock which known as external clocking. Example DTE device is router or serial port computer.

For CISCO configuration syntax to check DCE or DTE:
R1# show controllers s0/0/0 or R1# sh co s0/0/0
Remember:
Always set clock rate on DCE port
R1(config)# int s0/0/0
R1(config-if)# clock rate 64000
R1(config-if)# no shut
Interface S0 0 0 Dce 1
Noted that 64000 is example usual value. You can put any number which you think suitable.
Always set bandwith on DTE port:
R1(config)# int s0/0/1
R1(config-if)# bandwith 64
Interface S0 0 0 Dce Login
R1(config-if)# no shut
Note: In Packet Tracer, set bandwith for DTE is unnecessary for the network to be usable in certain case. However set clock rate for DCE in Packet Tracer is a must.
