The carrier terminated the line on a Chrone Block and gave me the pin-outs on that punch-down block.
So I made up a cable and connected that cable from that Chrone Block to the Rj45.
With the following outputs, can I assume my cable pin-outs and connections are fine, because otherwise even layer 1 won't become ACTIVE. Or could I still have a cabling issue with TX+, TX-, TX= and Rx-?

"show isdn status" output says that Layer 1 is ACTIVE, so i feel there is no issue at physical layer.
However, Layer 2 of interface Serial1/0:15 is not in 'MULTIPLE_FRAME_ESTABLISHED'
state.
Make sure that your service provider's switch type is primary-net5. If not, modify your switch type accordingly.
The interface-specific ISDN switch setting will override the global switch setting.
Also Verify the T1/E1 is configured to match the provider's switch. To see the layer 2 negotiations between the switch and the router, use the privileged exec command 'debug isdn q921'
HTH, rate if it does ....
