A channel can take a single call. This section describes how to modify
channels for an installed E1 card and how to view the status of an
existing channel.
CAUTION: Do not modify channels unless a 3Com Technical Support
representative advises you to do so. Modifying an ISDN channel
disconnects any existing calls on that channel.
If you use Auto Discovery to add channels on an E1 PRI line, note that the
30 channels discovered are numbered 1 through 15, and 17 through 31.
This reflects the physical channel mapping on the E1 interface, where
channel 16 is the ISDN D-channel, used for signaling.
To modify a channel on an installed E1 card:
1 Return to the Digital Line Cards tab (Figure 98).
2 Select ISDN PRI Channel List from the Select Device Type pull-down list.
3 Click Apply.
Figure 104 shows the ISDN PRI Channel List.

4 Select the channel that you want to modify.
