Changing BRI Group Membership
You may want to change the channel membership in a group to 
accommodate changing needs.
To change group membership:
1On the Digital Line Cards tab, from the Select Device Type pull-down list, 
select ISDN BRI Group List and then click Apply.
2Select the group for which you want to change membership.
3Click Membership. The Manage Group Membership dialog box 
(Figure 87
) appears.

4To add a channel to the Member List, select the channel in the Non 
Member List and click 
						

							252CHAPTER 3: DEVICE CONFIGURATION
5Optionally enable the Refresh Channels on Add/Remove check box. This 
refreshes each channel as you add or remove it.
You cannot move a channel from the Member List to the Non-Member 
List.
Each channel must belong to a group. A channel can belong to only one 
group at a time. You cannot move a channel from the members list to the 
non-members list of a group unless the system can assign the channel to 
another group. If a channel has never been a member of another group, 
the system cannot determine a group to which it can move the channel. 
Therefore, it cannot remove the channel from the member list. If a 
channel has been a member of another group in the past, the system 
moves the channel to the group of which the channel was most recently 
a member.
Example: By default, the system creates two groups, Group 1 and Group 
2, and places all channels in Group 1. If you try to move a channel to the 
non-member list of Group 1, the operation fails. If you select Group 2, 
click Membership, move a channel from the non-member list to the 
member list, and then move the same channel back to the non-member 
list, the operation succeeds because the channel was previously a 
member of Group 1. If you then view the Group 1 membership list, it 
contains the channel you just removed from Group 2.
6Click Close.
Removing a BRI Group

To remove a group:
1Return to the Digital Line Cards tab.
2From the Select Device Type pull-down list, select ISDN BRI Group List.
3Click Apply.
4Select the group you want to remove.

Modifying BRI Card
ChannelsA 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:
1On the Digital Line Cards tab (Figure 98
), from the Select Device Type 
pull-down list, select ISDN BRI Channel List.
2Click Apply. The system updates the window to show the BRI channels. 
See Figure 88
.

3Select the channel that you want and click Modify. The Modify Channel 
dialog box (Figure 89
) appears.

Span ID/Device #The span number and device number.
Group NameA name that helps you identify this group in a list.
Channel NameEnter a unique name for the channel.
Trunk to TrunkUnrestricted enables and Restricted disables the transfer 
of incoming calls to another line card port. Example: You 
could enable Trunk to Trunk transfers to connect a Voice 
Over IP (VOIP) gateway to a line card port and let callers 
use the system to access the telephone system from a 
remote location and use it to make CO calls.
AutoExtThe extension to which an unanswered call on this line 
card port is directed. You can assign a different AutoExt 
for each period of the day: Open, Closed, Lunch, and 
Other.

Configuring and 
Managing E1 
Digital Line CardsThis section describes how to add and configure an E1 Digital Line Card 
(
3C10165A) to connect to an E1 service provided by the local telephone 
company. In the NBX NetSet utility, Digital Line Cards are referred to as 
either cards or boards.
This chapter covers these topics:
■Adding an E1 Digital Line Card
■Configuring the E1 Digital Line Card
■E1 Card Status Lights
■Modifying an E1 Card
■Adding or Modifying an E1 Group
■Modifying E1 Card Channels
■Modifying IP Settings for an E1 Card
■Removing an E1 Digital Line Card
You can configure an E1 Digital Line Card for ISDN PRI signaling only. 
						

							260CHAPTER 3: DEVICE CONFIGURATION
Adding an E1 Digital
Line CardThese sections tell you how to add an E1 Digital Line Card to an NBX 
system:
■Preparing the NBX System for E1 Cards
■Ordering DID, CLIP, and MSN Services for E1
■Inserting the E1 Digital Line Card
Preparing the NBX System for E1 Cards
Before you insert the E1 Digital Line Card into the chassis, order an E1 
line, with the specifications you want, from your telephone carrier, and 
have them install the line.
Ordering DID, CLIP, and MSN Services for E1
When you order E1 with DID, CLIP, or MSN services, the local telephone 
carrier assigns a block of telephone numbers to you. Usually, you can 
request a specific range of numbers, but sometimes the carrier assigns 
numbers other than the ones you request.
You may be able to request that the local telephone carrier pass you a 
specific number of digits for each incoming telephone call. Sometimes 
the carrier does not offer any choice. In either situation, you need to 
know how many digits the carrier passes.
Example: Carriers commonly pass either the last three digits or last four 
digits of the number for each incoming call.
Sometimes the last digits of the telephone numbers the carrier assigns to 
you do not match the telephone extension numbers you want to use for 
internal calls. You can create entries in your Dial Plan configuration file to 
translate the incoming numbers into the corresponding extension 
numbers.
Example: You want to use internal extensions from 4000 through 4999, 
but the local telephone carrier assigns you numbers from 617-555-3500 
through 617-555-4499. You can create translator entries in the Dial Plan 
configuration file to translate an incoming digit sequence such as 3795 
into extension number 4295, and a sequence such as 4213 into 4713. 
The configuration would require several translator entries to handle 
subsets of the total range. A unique set of entries would handle incoming 
digit sequences from 3500 through 3599, from 3600 through 3699, and 
each of the other sequences in which the first two digits were unique in 
the range from 37XX through 44XX.
