2 Select the group, or groups, that you want to delete and click Remove
Selected. To select all groups, enable the Select check box.

The number of channels per span varies according to the configuration.
Each channel can accommodate a single telephone call.
This section describes how to modify channels for an installed card and
how to view the status of an existing channel.
If you use Auto Discovery to add channels on an E1 PRI line, note that the
30 channels the system discovers are numbered 1 through 15, and 17
through 31. This reflects the physical channel mapping on the E1
interface, in which channel 16 is the ISDN D-channel, that is used for
signaling.
CAUTION: Do not modify channels unless a 3Com Technical Support
representative advises you to do so. When you modify an ISDN channel,
you disconnect any existing calls on that channel.
