I can help.
You are correct. You have a Sprint CTX and a 4-port Protege Voice.
The 4 VM ports are probably 222, 294, 223, and 295. The Protege Voice takes one digital port and splits the B-channels (D+2B) technology.
The CTX cabinet needs Sprint software as you are aware.
To communicate with the Protege Voice you need:
- IBM-comtatible computer with an available serial port.
- Communication software package capable if TVI terminal emulation.
- A serial cable.
I know Windows XP works, but I have heard that XP Pro doesn't work. I have heard that a USB port works with the proper cable. I have heard that Windows Vista works, but I have not verified this personally.
Both the Protege Voice and Protege CTX run under DOS. You can either Boot to DOS or the Command Prompt works.
To communicate with the Portege Voice Procomm and Procomm Plus work, Hyperterminal does not work.
The terminal settings for Procomm are:
9600 baud, no parity, 8 data bits and 1 bit stop.I can help with the manuals and software. I will send you a PM with contact information.
