NEC 2400IMX DRU Installation

[DeltaDJR]

I just purchased a SP-DAIA DLI Card and a DRU-30A-B for use with my 2400IMX. I've installed the DLI Card in the last available 32 bit slot in the stack PIM0 SLot 23. The LEDs indicate a good link, and I have run the loopback tests to verify a good connection, but when I try to activate a circuit on any LEN (first=001200) I get a "Group Mounting Error (Unmounted or Unmatched). (Error 0x0102)"

Can anyone shed some light on why I might be getting this message?

In case it helps, the adjacent card is a PA-24DTR.

Thanks in advance.

Possibly that slot is where your conference trunks are programmed. If you have another slot try moving it.

Do not use the first 8 time slots . Reprogram starting with 001210.

After further investigation try racefans idea. Something is programmed in that slot.

When using the DLI Card in some of the lower slot numbers (i.e. slots 5 and 7), do I need to make sure the next slot is vacant because this is an E1 card?

I was under the impression that when using a 32-bit card in a 16-bit slot, you needed to leave the next slot in the PIM open, and I have no more 32-bit slots left.

Thanks for the replies!

When insalling a DRU you use the start with the first level.
i.e. a slot with 016,017,018,019 you would program the first station on XXX160.

After doing a LLEN on the LENs associated with slot 23, I see that there are several routes programmed on various LENs. According to the manual, I can use slots 5,8,16, and 18, but when I put the DLI board in those slots and activate the MB switch the N-OPE LED stays lit and OPE will not go green. Specifically, I tried slot 7 and verified that nothing was programmed on LENs 010060-010090 plus 010300-010317, but when I turn the card on N-OPE stays lit. Any ideas?

You have to program a LEN before the card will come on line.

I tried programming a LEN but the OPE light on the card still does not come on in that slot.

What TEC are you assigning these stations?

 

[grh959]

Just to clarify, the DAIA is an analog DRU not for digital phones, if the TEC is assigned as a 12 instead of a 3 this will behave like this.

 

[DeltaDJR]

I am using a TEC of 3. I've actually used this same configuration before, I am just confused as to why I can not make it work in the slots that the manual says it works in.

I have my problem solved, and thanks to everyone who helped. Here's my mistake. Once I discovered I could not use my last 32-bit slot, I moved to an available 16-bit slot in the upper PIM. When I did that, I made a mistake in the LEN number because I had the module group wrong in my head. Once I stepped back and took another look at the situation, I had been using the wrong LEN all along. I am feeling really bone-headed at the moment, and I have the label-maker fired up ready to help me make sure I don't do that again.

Thanks to all that assisted me with this issue.
