My nec dterm 80 has a light blinking on one of the lines . how to get rid of it.
If the red light at the top of your phone is blinking it can mean three things: You have a voicemail, in which case you need to press VM at the top of your phone and listen to each message. You have a message waiting request. In this case you should see MW on the display of your phone.

Can i add an external paging speaker to my nec dtu-16d-2 phone?
Again..... insufficient information. I PRESUME you have an NEC system of some type and ASSUME you have an external paging system. IF this is so, THEN there are normally separate adjustment on the Page pac for ringer and paging. Someone probably messed with the input signal or the output volume or the impedance was wrong to begin with.
