Sanju,
1) You mentioned wic-1t and 2t but I suppose you are using the serial modules on both sides, right? If so, yes it should be ok.
2) For a back to back connection, you need to set the clockrate on the DCE. Also, JUNOS uses PPP as default encapsulation, whereas IOS uses hdlc. Make sure you change one side or the other.

3)You shouldn't need to do anything special on the Juniper side except for using the right cable (DTE). The DTE mode should be detected automatically.
If this doesn't work, please provide a "show interface
Also do not forget to change the encapsulation on one side or the other as the default values are different.
