Will a WIC-2T support one port DCE and the other DTE?

I'm running a 2600 router connected to an encryption device (KIV-21) via a WIC-1T serial port. When I swapped out the port and replaced it with a WIC-2T, the line protocol remained down even though the port is up. The show interface command also reveals the LAPB DCE state is "SABMSENT". The router and kiv configurations are identical to when the WIC-1T was installed. The only difference is now I'm running a second serial line with the other WIC-2T port as DTE. Will a WIC-2T support both DCE and DTE at the same time? Any support is appreciated.

What's your serial interface configuration ?

Did you configure a "clock rate " command on the DCE interface ?

Could you try to configure "no keepalive" on the serial interface.

If it's still doesn't work, please provide the show interface + show controller serial output.
