Question about NEC Electra Professional ETW-16DC-2
I would like to upgrade my phone system to handle more incoming phone lines. I currently have CO1-C(4)-10 KTU card and CO1-C(2)-10 KTU smaller card. Does anyone know what I would need to handle another 4 incoming phone lines?
The NEC Electra Professional Level 1 has a maximum CO line capacity of 8 in any configuration. If you need more outside phone lines, you will need a different system. If you need to limit cost as much as possible, the cheapest avenue would be to upgrade to a used Electra Professional Level II. That way you can still use the same telephone instruments, but ALL cabinet hardware would be different. Also, you can only get to 8 outside lines if you have software level 3.00 or higher by using the COI-C(2A)-10 card. To verify which software version you have, I think you press FNC(3) on sta. 10 ( or the first station in the system). If that doesn't work, let me know, and we can access the system program to verify version number.
