Section 2: General operation
In this dialog box, you can set:
•
Label: The label for the channel. This is the same as the command channel.setlabel().
•
Forbidden: Select this box to set the channel to forbidden. This prevents the channel from being
closed from any interface. Note that if the channel is used in a channel pattern, the pattern is
deleted when you set the channel to forbidden to close.Delay Time: The additional delay to incur
after the relay settles when closing. Enter the value for the delay in seconds. The total delay for
channel close is this delay plus the relay settling time.
This dialog box also displays the closure count. See
page 2-93) for information.
Set up channel patterns from the web interface
You can use channel patterns as a convenient way to refer to a group of switching channels with a
single alphanumeric name. When you perform close or open operations on a channel pattern, only
the channels that are in the channel pattern are affected.
There is no speed advantage in performing close and open operations on channel patterns compared
to performing the same operations on individual channels or a list of channels.
To create a channel pattern from the web interface:
1. From the left navigation, click a slot.
2. Click Pattern (above the Channel Action Type box). The Channel Pattern Configuration dialog
box is displayed.
