z

When purchasing a SIC-1VE1 interface module, users should purchase a VCPM and configure a
VPM based on voice traffic.

z

No VCPM is required, but only a VPM needs to be installed on the main board when MSR 20-1x
series routers need to be equipped with a SIC-1VE1 interface module.

z

VCPM and VPM need to be installed on the main board when MSR 30 series routers need to be
equipped with a SIC-1VE1 interface module.

z

VCPM and VPM need to be installed on the MSCA module when MSR 50 series routers need to be
equipped with a SIC-1VE1 interface module..

DIP switches

CE1/PRI/R2 interface is compatible with 75-ohm and 120-ohm impedance. Matching of different
impedance is implemented through an 8BIT DIP switch. By default, all the DIP switches are set to ON,
as illustrated in the following figure:
