Voice Processing Module (VPM)
The 4 port Voice Processing Module is a small removable hardware board called a VPM. It connects to the SVMi-
8E/SVMi-16E motherboard. When it is installed in the SVMi-8E/SVMi-16E card it increases the number of available
ports by 4.
IMPORTANT NOTE: The VPMs used in this product appear very similar to the VPMs in our previous CADENCE and
SVMi-8 products, but they are not interchangeable. If the VPMs are not labeled with the letters SEC and/or do not
say VPM02 they will not work in the SVMi-8E/SVMi-16E products.
The VPM is used to:
■ Move the digital speech and fax information between the SVMi-8E/SVMi-16E system and the phone system.
■ Generate and detect DTMF
■ Record and play back speech
Each VPM has 4 channels. This means that for each VPM installed, up to four additional simultaneous callers can
be connected to the SVMi-8E/SVMi-16E.
The VPM is attached to the SBC by an edge connector.
The SVMi-8E card can accommodate 1 of these cards allowing up to 8 simultaneous callers. The SVMi-16E card
can accommodate up to 2 of these cards allowing up to 16 simultaneous callers. The SVMi-8E card can not be
expanded beyond 8 ports, and the SVMi-16E can not be expanded beyond 16 ports.
