NOTE:
•
The console port and AUX port of MSR 20-1X routers share one RJ-45 interface.
• Two SIC slots can form one DSIC slot.
• MSR 20-12 and MSR 20-15 can implement voice data processing without any VCPM card. If you need
voice support, insert a VPM card into the VPM slot on the main control board, and then install a
SIC-1VE1 or SIC-1VT1 on the router.
• Only MSR 20-12 and 20-15 can support SIC-1VE1 and SIC-1VT1.
• MSR 20-12, MSR 20-13, and MSR 20-15 all include two sub-models. One sub-model supports WLAN
and the other does not. You can purchase the appropriate sub-model as required.
• The Boot ROM stores the Bootstrap for booting the router.
• The memory stores the communication data between the system and the CPU during the system
operation.
• The flash memory stores the BootWare, the software system and the configuration file of the router.
• Do not unplug the USB device during USB data transmission; otherwise, data loss or even hardware
failures may occur.
• The wireless module can not be purchased separately.
• By default, the impedance of the fixed E1 interface on MSR 20-12 is 75-ohm. Using the internal DIP
switches, users can change the interface impedance from 75-ohm to 120-ohm. For detail information,
refer to Chapter 6 “Hardware Maintenance”.
