| As Pirate_Ghost pointed out, you can "view" unused DN's and TN's in LD 20.
For TN's:
REQ luvu
TYPE 500 (or 2216 or 3905 etc) for phantom loops, use 500 as type
TN (leave blank)
CDEN (leave blank)
...the switch will return a list of unused TN's. If you don't get some saying "PHANTOM", then you must first configure the phantom loops.
For DN's:
REQ prt
TYPE ludn
CUST (leave blank)
DN (leave blank OR use the first one or two digits, for example "21" if you want to see all the spare DN's starting with 21nn) |
