Overview of the VISM and VISM-PR Cards
This chapter provides a general introduction to VISM and VISM-PR and describes the hardware and
software modules, and installation procedures. The following topics are described:
• “VISM and VISM-PR Card Types” section on page 1-1

Note The term VISM is used to refer to the product software—either for the VISM card or for the

The VISM card, in combination with a Cisco MGX 8000 Series platform, enables telephone calls on
conventional time-division multiplexed (TDM) voice circuits to be transported over an Asynchronous
Transfer Mode (ATM) packet-switched and VoIP networks. The VISM card is a single height card
designed to operate in the following platforms:
• Cisco MGX 8850 Release 1, wide area switch
• Cisco MGX 8250, edge concentrator
• Cisco MGX 8230, edge concentrator
Note VISM is not supported on the Cisco MGX 8260 switch.
