156• Do not install a VCPM on the MSR 20-12 router when installing a SIC-1VE1/SIC-1VT1 moduleon them. Each main board of the MSR 20-12 routers provides only one VPN slot. Thespecifications and number of VPMs needed depend on the number of calls. Installation shouldbe performed by H3C personnel or an authorized H3C partner.• The multi-service module A (MSCA) of an MSR 50 router provides VCPM and VPM slots, butthe multi-service module B (MSCB) provides only one VCPM slot. No VCPM and VPM slots areinstalled when MSR is shipped.• Install VCPM and VPM modules on a MSCA when installing the SIC-1VE1/SIC-1VT1 on theMSR 50 routers. The specifications and number of VPM modules needed depend on thenumber of calls.• The FIC-1VE1/FIC-1VT1 module provides one VCPM slot and one VPM slot and theFIC-2VE1/FIC-2VT1 module provides one VCPM and two VPM slots. The FIC-2VE1/FIC-2VT1module has a VCPM installed when MSR is shipped.• The VCPM module installed on the MSCR/MSCB of an MSR 50 router is different from thatinstalled on the FIC-1VE1/FIC-1VT1 module. Therefore, they cannot be used interchangeably.• The FIC-1VE1/FIC-1VT1 is used with a VPM module installed. The specifications and numberof VPM modules needed depend on the number of calls.• The VPM modules installed on the MSCA of the MSR 50 routers are the same as that installedon the FIC-1VE1/FIC-1VT1 modules.• If you install more than two FIC-1VE1/FIC-1VT1 modules on an MSR 50 router, you need to addanother VCPM module on the MSCA/MSCA.VCPMIntroductionThe voice co-processing module (VCPM) provides transmission channel between DSP strip andsystem memory for voice data, thus implementing TDM HW exchange for each PCM data voicechannel.VCPM module is required for voice communications of routers.Interface specificationsTable 212 Interface specificationsItem DescriptionConnector Double-edge connectorInterface type PCI 2.2, EHPIData transmission rate• Operating rate for PCI bus: 33 MHz/66 MHz• Maximum bandwidth: 264 Mbps• BURST transmission: Up to 1 KB of data can be transmitted once and themaximum number of bytes transmitted can be configured.
