I have installed a NEC Electra 48 with a voicemail Elite in slot 07 for a friend that wanted to reuse it from another site ( I mostly work on Avaya )

I worked on them awhile ago but can get around logging into x100 or x101 ...also using cosession for the voicemail

*my question is this we have ports 01-08 (x100-107) on the first 8 pairs ...w/blue to rd/grn pairs

(4 port co card in slot 02) pairs 9-12 for co # 1 - #4
rd/brn to black/orange pairs

8 port Digital card in slot 03 pairs pairs 16-24
yellow/orange to v-/brn pairs

since we are adding more co trunks I programmed slot 04
for a 4 port co card ...card is back ordered ....I will
install it at a later date ...can the co card be installed
while the power is on I know if you do anything with the voicemail card you make busy with the dip switch on vm card and wait 45 - 60 seconds before pulling card ...I programmed all the phones for lines 1-8 and dit day to ring voicemail ....

will trunks 5-8 fall on the second amp pairs 1-4 being w/blue to w/brn pairs

is there a cheat sheet for the color code depending on what card you install in what slot ???I looked through a Manual
on cd and found nothing

its a pretty nice little system for the small business
world and the customer has some other bigger NEC systems
through out the country ....like I said we mostly deal
in Avaya systems but did this for a favor for them

Thanks for any and all posts
