SIC-1VE1 45
Step 2: Check the status of LINK LED on the GEC panel: ON means the link is
connected and OFF means the link is not connected. In the latter case, check the
line.
SIC-1VE1
Introduction 1-port E1 voice interface card (SIC-1VE1) can handle dense voice signals in VoIP
system. It provides a CE1/PRI/R2 port, allowing the access of 30 channels of voice
signals.

■ When purchasing a SIC-1VE1 interface card, users should purchase a VCPM
and configure a VPM based on voice traffic.
■ 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
card.
■ 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 card.
■ VCPM and VPM need to be installed on the MSCA card when MSR 50 series
routers need to be equipped with a SIC-1VE1 interface card.
Interface Attributes
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:
