Modifying BRI Card
Channels
A channel is an ISDN logical B channel. A channel can take a single call.
This section describes how to modify channels for an installed BRI 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 BRI-ST card:
1 On the Digital Line Cards tab), from the Select Device Type drop-down
list, select ISDN BRI Channel List.
2 Click Apply. The system updates the window to show the BRI channels.
3 Select the channel that you want and click Modify. The Modify Channel
dialog box appears.
4 Fill in or change the fields in the appropriate Modify Channel dialog box.
Table 45
describes each parameter.
5 Enable the On Line check box to bring the channel on line. Note that the
channel does not come online unless, previously, the card and the span
have come online. Click OK.
