I am trying to setup a PRI on an 11c. I have an NTAK09,NTAK20 and an NTBK51 in slot 6. In following the NTP I add a DDB in LD73, then in LD 17 I add a DLOP with DLOP 6 24 ESF. So far so good. Then in following the NTP to add the D-Channel I use NEW DCH 15 under ADAN with CTYP MSDL. The next prompt asks for CDNO. The description says "Card slot number to be used as the primary DDCH/DCHI". The range is 1-9 so thinking this is THE 11c slot the card is in I enter 6 to get back:SCH3722 Added loops must be of the same type as DCHL(?). If I enter any other value from 1 to 9 it passes, so I play along. A little later the prompt is DCHL and the description says "Must match entry made for CDNO". Now the choices are again 1-9 and the only one I can not enter is precisely the choice I made for CDNO above. Is this an evil plot from Nortel or am I just plain crazy. Can anyone point me along to help rectify this? Siggghhh. TIA.
