You should connect a cable to the port with the correct mark. Misplugging is prone to impair the
interface module and even damage the router.

VCPM/VPM Purchase Guide
z
The main boards of the MSR 20-40 and 30 series routers provide voice co-processing module
(VCPM) and voice processing module (VPM) slots, but have no VCPM and VPM modules installed
when MSR is shipped from the factory.
z
The SIC-VE1/SIC-VT1 module does not provide any VCPM or VPM slot, and can only use the
VCPM and VPM installed on the main board of MSR.
z
The MIM-1VE1/MIM-1VT1 module provides a VCPM and a VPM slot, and the
MIM-2VE1/MIM-2VT1 module provides a VCPM and two VPM slots. Each MIM-VE1/MIM-VT1
module has a VCPM installed but has no VPM installed when it is shipped from the factory.
z
The VCPM module used for the main board of MSR 20-40 and 30 series routers and the VCPM
module that comes pre-installed on the MIM-VE1/VT1 module are different and cannot be used
interchangeably.
z
The VPM module used for the main board of an MSR 20-40 or 30 series router is the same as that
installed on the MIM-VE1/VT1 module
z
When you install a SIC-VE1/SIC-VT1 module into a supported MSR 20-40 and 30 series routers,
then you also need to install a VCPM and VPM on the main board of the MSR. The number of
VPMs needed depends on the number of calls. Installation should be performed by H3C personnel
or an Authorized H3C VCX partner.
z
The MIM-VE1/VT1 module must be used with VPM installed. The number of VPMs needed
depends on the number of calls.
z
If you install more than one MIM-VE1/MIM-VT1 modules (or one MIM-VE1/MIM-VT1 module and
one SIC-VE1/SIC-VT1 module) into a supported MSR 30 series router, you need to add another
VCPM on the main board of the MSR.
z
If you install a single MIM-VE1/MIM-VT1 module into MSR 30 series routers, no more VCPM is
needed.
z
Because the initiator of a three-party conference is responsible for audio mixing, so when using
MSR as the initiator of a three-party conference, the main board of MSR must have VPM installed.
z
Do not install a VCPM on the MSR 20-12 or MSR 20-15 router when installing a SIC-VE1/SIC-VT1
module on them. Each main board of the MSR 20-12 and MSR 20-15 routers provides only one
VPN slot. The specifications and number of VPMs needed depend on the number of calls.
Installation should be performed by H3C personnel or an authorized H3C VCX partner.
