Can an MISP Loop be next to a Superloop?

I’m looking to install ISDN line service at a location that I work at and have some questions. I need to provide 6 ISDN BRI lines for two separate video tele-conferencing (VTC) systems. The switch is an Option 61C that was later upgraded to an 81C.

I know the steps and everything to set up ISDN BRI line service for my switch, but I’m not sure about the MISP Loop.

I have superloops set up in core/net module 0-1, the superloops are 20, 24, and 28. I need to install ISDN line cards (UILC) in shelf 20-0 and 24-1. Do I need only one MISP or do I need two, and where do I install the MISP card? I know I can only install in slots 0-7 in a core/net module but I am not sure if I can install an MISP Loop that close to a superloop, i.e. MISP loop 22, 26, or 30.

Any and all help is appreciated.
 
Superloop 20 uses all of Loops 20-23, Superloop 24 uses all of Loops 24-27 and Superloop 28 uses all of Loops 28-31, so to answer your question no you can't put a MISP in Loop 22. 26 or 30.
 
Thanks for the reply, that is what I thought but was not sure. If the core/net module is full then can I put the MISP in another network group and point the line cards to it?
 
Yes the misp can be placed in any network group.
 
Thanks,

Just for clarification, let me see if I understand this correctly.
So, I can put an MISP card in Network group 1-1, let's say loop 58, and install UILC line cards in any shelf, lets say 20-0 or 24-1?
 
Yes you can, there is a recomendation to have the silcs on a superloop in the same network shelf to avoid tying up some inter group connections, but it will definately work.
 
OK, then maybe I did something wrong. I have an MISP installed in network group 1 loop 58, I have a BRSC card installed in IPE 48-0 with 5 UILC cards. I should be able to assoiciate at least 3 more UILC cards to the MISP. I tried to install a UILC card in IPE 112-1 and got an error that said in could not find the MISP loop.

Got any ideas. I know I could put an MISP card in network group 3 and then install up to 4 UILC cards in the same network group and it would work. Looks like I can only install UILC cards in the same network group as the MISP card.
