Introduction
1-port T1 voice interface module (SIC-1VT1) can handle dense voice signals in VoIP system. It provides
a CT1/PRI/R2 port, allowing the access of 23 channels of voice signals.
z
When purchasing a SIC-1VT1 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-1VT1 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-1VT1 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-1VT1 interface module.
