Hello Rakesh,
I am not sure about the switch configuration, but in-general when it comes to activating the link the following points should be taken care.
T1/E1 properties,
Clock External/Internal
Frame Type
TimeSlot
If the above are not set properly then MTP2 might not find the link in active stage.
SLC and DPC
If there is a miss-match between the SLC and DPC on a link then the SLTM/SLTA link test procedures are expected to fails, becasuse of which the link will not be in “active state”.
