Configuring and Managing T1 Digital Line Cards 315
Modifying T1 Card
Channels
A channel is either a T1 DS1 or T1 ISDN PRI time slot. Each channel can
accommodate a single telephone call. This section describes how to
modify channels for an installed T1 Digital Line 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.
To modify a channel on an installed T1 card:
1 Return to the Digital Line Cards tab (Figure 98).
2 From the Select Device Type pull-down list, select either T1 Channel List
(for T1 channels), or ISDN PRI Channel List (for T1 PRI channels).
3 Click Apply .
The window that appears depends on the channel list you select.
Figure 132 shows the T1 Channel List.

4 Select the channel that you want to modify.
5 Click Modify . The dialog box that appears depends on the channel list
that you selected.
