The System Resources screen provides a summary of key resources and their current usage in the system.

  This table lists details of various resource channels.

• Channels
  One of the following:

• VCM Channels
  The system uses voice compression channels for calls between IP and non-IP devices (trunks and or extensions).
• Data Channels
  The system uses data channels for Remote Access (RAS), Internet Access, and voicemail sessions. A data channel is an internal signaling resource used whenever a call goes between the IP network and an exchange line. For example, four people surfing the Internet will use a single data channel since they all share the same line to the ISP. Two people remotely accessing the Office LAN from home will use two data channels since they have dialed in on separate lines. IP extensions do not use data channels.
