NOTE:
•
MSR20-12-T-W(NA) and MSR20-13-W(NA) are North American models.
•
Before installing a SIC-1VE1 or SIC-1VT1 module to the MSR20-12/20-12-W/20-12-T/20-12-T-W(NA),
purchase a VPM module and install it to the VPM slot on the motherboard.
•
By default, the impedance of the E1 port on MSR20-12/20-12-W is 75 ohms. By using the internal DIP
switches, you can change the interface impedance to 120 ohms. For more information, see the chapter
“Appendix C Setting the fixed E1 port impedance.”
