You may want to modify a Digital Line Card group to change its name, 
Auto Extension assignments, or other parameters. When you modify a 
group, the changes affect all the Digital Line Cards assigned to that 
group. To modify a Digital Line Card group:

select one:

■

■

ISDN PRI Group List (for T1 ISDN PRI)

2 Click Apply.

3 Select the group that you want to modify.

4 Click Modify. The dialog box that appears depends on the Group List that 

you selected either the T1 DS1 Modify Group dialog box or the T1 ISDN 
PRI Modify Group dialog box.

5 Make the desired changes to the group parameters. See the Help for 

details on each parameter.

6 Enable the On Line check box to bring the group on line.

7 Click Apply to effect the changes.
