Is there anyway to send the serial number from a M2008 or M2616 set to the admin terminal? The situation I am dealing with is as follows: I have several existing sets with the same DN's, in LD 20 I did an IDU on all the sets but some sets do not have there serial numbers marked on the back. Also note I am working with a Meridian 1 Option 61C. Any input on this subject would be greatly appreciated.
