private line DN/route

[coniglio]

what does the fact that the below PRDN has no route mean?

DN 175
TYPE PRL
ROUT NONE
MBER 0
TN 007 0 00 15 KEY 03 MARP DES 65 15 SEP 2003
(2317)

is there any way for me to identify this number so I can disconnect it if it's not in use? thanks in advance.

i am at a remote site (should've specified that) that's why I can't simply get the number myself from the block.
