| not sure how this works, but I have attached the new table referred to earlier which tells you what software level you have based upon the SP version found in maintenance. Also, XC software is not required for a 3rd DTI card, just a trunk module. However Nortel recommends 2 Fiber COMBO cards when installing 2 DTIs or more IF you are using standard E&M trunking to increase the number of DTMF receivers, and thus XC software would be required. Again, NA Software supports 1 expansion cartridge, and XC Software supports up to 2 expansion cartridges. Brewsky |
