Block/Enable Command
The Block/Enable command is used to block or to enable a given switch link. Blocking a link means that only previously established connections or sessions (device and call monitors) will remain active on the link. Additionally, new Telephony Services or CVLAN application requests using a call ID or monitor previously established over the link will be serviced. No other new Telephony Services or CVLAN application requests will be allowed over the link.
For example, if a device was already being monitored using Link 1 before it was blocked, the monitor will remain active. If a Make Call request was issued over Link 1 and the call ID is still active, any Hold Call and retrieve call requests using that call ID will succeed. If the call ID (from a previous Make Call request) is still active, it is possible to issue a device monitor on the calling deviceID. However a Make Call request or a monitor of a completely different device will not be serviced using a blocked link.
Figure 3-4 shows the Block/Enable screen. To change the state of a link, click on the appropriate state, Enabled or Blocked, and select OK.
