E1 on Solaris box

hi,

can someone please guide me if there is any special hardware to use when we need to terminate an E1/T1 link on a Solaris10 box. I have a number of boxes and these all are located at longer distances. the only connectivity is the E1 links between these far location locations.

Would it be possible to use E1 links ( cable terminate into an RJ45 connector at both ends ). by attaching them to igb0 and igb1 ethernet ports or do I need to have some additional equipment. in a simple line, can solaris handle directl E1/T1 lines terminating to its ports and how.

Regards,
Nasir
