Device Configuration section is used for adding and configuring
hardware on your 3Com NBX System. The Administrator's Guide found within
the administrator's section of NetSet goes into great detail for each
topic listed below.
Adding, Removing, and Modifying Telephones
This section describes how to add, remove, and modify telephones in the
NBX NetSet utility. You can also review the status of each device and
configure button mappings for NBX telephones.
Adding a Remote Telephone
NBX system software (release R4.2 and higher) supports Network Address
Port Translation (NAPT, also called NAT overloading). NAPT allows you
to put an NBX Telephone behind a device that applies network address translation
at a remote location, such as a home office, and connect to the NBX call
processor through an Internet connection. One typical configuration is
to connect a cable/DSL modem to a small office/home office router that
includes a firewall and Ethernet ports. You connect the NBX Telephone
directly to one of the Ethernet ports. Another option is use the pcXset
soft telephone application instead of an NBX Telephone.
Creating and Managing Bridged Extensions
Bridged extensions allow you to have the extension of a primary telephone
appear on one or more secondary telephones. Most activities associated
with the extension can be performed on both the primary telephone and
any of the secondary telephones. However, you cannot use a bridged extension
on a secondary telephone to place a call.
Creating and Managing Telephone Groups
Telephone groups let you create common Button Mappings. Button mappings
let you assign specific actions to the buttons on an NBX Business Telephone.
When you associate a Group with a specific telephone, the telephone inherits
all the mappings of the Group.
For example, you can create a Group called Sales that includes Access
buttons mapped to a set of CO lines. When you add a new salesperson to
the group, you simply specify the Sales group for the telephone assigned
to that person. All of the Sales group’s Button Mappings are then
available on that person’s telephone.
Recording and Monitoring Telephone Calls
If you have call recording application software that runs on a PC that
is external to the NBX system, you can record and monitor telephone calls
to and from telephones on the NBX system. To enable call recording and
monitoring on the NBX system, you must purchase a system-wide license.
After you install the license, you can enable call recording and monitoring
for these devices:
- Analog telephones
connected to ports on an Analog Terminal Card or to a single-port Analog
- NBX Telephones
- Telephone Groups
and Managing Button Mappings
Button Mappings allow you to place features, such as speed dial numbers
and shortcuts, on telephone buttons for individual telephones or for telephone
groups. In addition, you can use Button Mappings to map CO telephone lines
to buttons and set up your system in one of these modes:
- Key Mode
system — In Key Mode, all outside lines map to individual
buttons on users’ telephones. You can share lines by assigning
one line to multiple telephones. Incoming calls ring on all telephones
that have that line assigned. Any of those telephones can answer the
- PBX (Private
Branch eXchange) system — In a PBX system, outside lines
are pooled and arbitrated by the Call Processor. To call an outside
number, a user must dial the line pool access number, typically 9, and
the Call Processor assigns the next available line.
Mode system — In hybrid mode, some lines are assigned
as keyed lines, while the rest are pooled.
You must use NBX
Business Telephones to operate the system in key mode or hybrid mode.
NBX Basic Telephones operate in PBX mode only.
Device IP Settings
If you are using Standard IP network protocol, you can manually change
the IP address of telephones, Line Card ports, Attendant Consoles, and
Analog Terminal Cards. You modify the IP settings of a device if you plan
to move the device to a different subnetwork than the one on which the
Call Processor resides. If the new subnetwork is served by a DHCP server,
the IP address you assign to the device must be outside the address range
that the DHCP server uses.
3C10116D T1 and
3C10165D E1 Digital Line Cards can be installed in a remote location and
communicate with their NCP over a routed network.
When you park a call, anyone can retrieve
it from any other telephone in the system by entering the Call Park extension
that is associated with that call. Example: You need
to transfer an incoming caller, but the person that you need to reach
is not available. You can park the call on any unused Call Park extension
and then page the person, announcing the Call Park extension where the
call is parked. The person can then retrieve the parked call from any
internal telephone by dialing the Call Park extension on which you parked
the NBX Attendant Console
The NBX Attendant Console provides
extended button mappings and displays the current status of each extension
mapped to it. A receptionist typically uses the Attendant Console to connect
incoming calls to telephone extensions.
and Managing Analog Line Card Ports
Each NBX Analog Line Card provides
access for up to four local telephone lines into your NBX system. The
Call Processor treats a line card port as an extension, so each line card
port needs its own extension number.
and Managing Analog Devices
An Analog Terminal Card (ATC) or
an Analog Terminal Adapter (ATA) allows ordinary analog (2500-series compliant)
telephones, including cordless telephones and Group-3 facsimile (fax)
devices, to operate with NBX systems.
and Managing BRI-ST Digital Line Cards
A BRI-ST Digital Line Card can be added and configured to handle a BRI
line with four BRI spans using the ST interface.
and Managing E1 Digital Line Cards
An E1 Digital Line Card can be added and configured to connect to an E1
service provided by the local telephone company. You can configure an
E1 Digital Line Card for ISDN PRI signaling only.
and Managing T1 Digital Line Cards
A T1 Digital Line card can be added
and configured to connect to a T1 service provided by the local telephone
Up a Digital Line Card at a Remote Location
Each 3C10116D T1 Digital Line Card
and 3C10165D E1 Digital Line Card can function as a standalone unit and
communicate with the NBX Network Call Processor over a routed network.
To function as a remote card, the card must have the normal IP settings
(IP address, default gateway, and subnet mask), and one extra setting,
the IP address of the NBX Network Call Processor.
Up T1/E1 Logging
The 3C10116D T1 Digital Line Card
and the 3C10165D E1 Digital Line Card can generate logging information.
The TEP (T1, E1, Primary Rate Interface) logs are stored on the system
disk drive and you can use the NBX NetSet utility to view, download, and
delete log files. Each card has a separate log, up to a maximum of five
log files. When a log reaches its maximum size, 5 MB, it begins to overwrite
the oldest data. Because TEP logging has a performance cost, it is disabled
by default. To enable TEP logging and to receive help interpreting the
log results, contact your 3Com NBX Voice-Authorized Partner.
CSU State Information and Statistics
3C10165D E1 cards and 3C10116D T1
cards have an onboard channel service unit (CSU). You can use the NBX
NetSet utility to view near end (local CSU) and far end (central office)
state information and statistics about each connected span.
The 3C10116D T1 and 3C10165D E1
cards can respond to commands from the Central Office to loop back data
at different points for diagnostic purposes. You enable each loopback
test using the NBX NetSet utility. You initiate the Local and Framer loopback
tests using the NBX NetSet utility. The Line and Payload loopback tests
must be initiated by the Central Office or by test equipment emulating
Central Office equipment.
