Introduction  
Lucent TURN-UP  
Lucent TURN-UP  
The CellPipe 20 Series Product Family supports the Lucent TURN-UPautomated  
CPE provisioning system. TURN-Up is enabled when a user powers up his unit and  
allows service providers to quickly and efficiently distribute and provision CPE gear  
without the use of truck-rolls. Furthermore, TURN-UP stores configuration  
information on a central server, making configuration management efficient and easy.  
Caution: If you attempt to manually configure the unit, TURN-UP will be disabled.  
To re-enable TURN-UP, you need to select the defaultcommand and reinstall the  
factory default configuration.

CellPipe 20 Series management  
CellPipe 20 Series units can be managed via three different connections:  
Console port  
Ethernet port  
WAN port  
CellPipe 20 series units are managed through a command-line interface (CLI). Also,  
rudimentary management can be accomplished with SNMP. You set up a connection  
between your computer and the device and use VT100 emulation software to display  
and change configuration information. See Chapter 3, Command-Line Interface,”  
for a description of all the commands in the command-line interface.

Setup  
Checking status lights  
Checking status lights  
Observe the activity pattern of the lights at the front of the CellPipe units to verify that  
they are connected properly.  
Figure 2-3. Status lights  
When all the cables are connected, verify that:  
The pwrlight comes on initially and remains on. If not on, make sure the power  
supply is properly connected.  
The actlight blinks during any LAN traffic. Otherwise it remains off.  
The lnklight is on if there is an Ethernet connection established. If not on,  
check to make sure your Ethernet cable is properly connected.  
The wanlight blinks until a connection is established and then it remains on.  
The conlight is on only during the unit self-test.  
Console setup  
You need to set up a serial connection between the unit and your computer to access  
the command-line interface and configure a CellPipe 20 Series unit.  
You need a 9-pin RS-232 serial cable to connect to the CellPipe unit through the  
console port.  
You also need a terminal emulation program, such as HyperTerminal, PROCOMM  
PLUS, Zterm, or any other program that supports VT100 terminal emulation, to open  
a session directly with the unit.

software to display configuration information on your computer and input commands  
and parameter values to configure and manage the unit.  
Syntax of command-line interface  
Syntax for the CLI is as follows:  
>> prompt means commands can be entered without password  
< > means the parameters are compulsory  
[ ] means the parameters are optional  
| between parameters means either/or  
...around parameters means the enclosed are key words  
A spaceis necessary between a command and its corresponding parameter

Using the commands  
The CLI of the CellPipe 20 Series consists of two hierarchical levels. Some of the  
second-level commands display values or status of the selected commands from the  
main level.  
Note: Access to the CLI is possible without a password. When user enables a  
password, the unit will time-out after 10 minutes if there is no activity on the unit.  
Re-entering password is necessary to resume activity.  
The CellPipe 20 Series units display two sets of main menu commands based on the  
mode of operationbridging or routing. The default list of main menu commands is  
for bridging. See Bridging commandson page 3-3. When selected for routing, the  
routing menus are displayed. See Routing commandson page 3-6.

This chapter provides general information for configuration of the various interfaces  
and procedures for administering a CellPipe 20 Series unit.  
Auto-provisioning  
All CellPipe 20 Series units support the Lucent TURN-UP automated CPE  
provisioning system. TURN-UP eliminates the need for user configuration of units  
and provides centralized management of configuration information.  
CellPipe20 Series Users Guide

Configuring a 20 Series CellPipe  
Configuring WAN interface  
When you power up the unit, it is set to default (factory settings) and the console will  
display the following message:  
Starting to download from remote server...  
This means TURN-UP is enabled and is downloading the latest configuration  
information.  
To disable the feature, interrupt the download and manually configure the system.  
To re-enable the feature, you need to select the defaultcommand and reinstall the  
factory default configuration.  
Configuring WAN interface  
Currently the 20 Series units support SDSL and ADSL WAN interfaces.  
SDSL commands and configurations  
The following is a list of the menus available under the sdslcommand:  
auto - <Enable>|<Fast>|<Scan>|<Disable> autobaud rate function  
cell - <Enable>|<Disable> idle-cell header  
dbit - configure the SDSL data bit as normal or reverse polarity  
default - set SDSL configuration back to factory setting  
enable - activate the last updated SDSL parameters  
maxrate - configure the SDSL autobuad max rate  
rate - manually configure the SDSL line rate  
scramble - <Enable>|<Disable> payload scrambling  
smbit - configure sign/magnitude bit sequence  
status - display the configuration and status of current SDSL  
setting

Preparing to upgrade  
To upgrade system software for a CellPipe 20 Series unit, you need to download to  
your computer the appropriate zipped file of the latest software release. Establish a  
serial connection between the unit and your computer for access to the CLI and also  
establish an Ethernet connection to the unit. Be sure the unit and your computer are  
configured properly so that you can successfully pingthe unit from your computer  
or vice versa.  
Obtaining software  
You can obtain the latest software release from the Lucent Technologies eSight™  
Service Center at http://www.esight.com.  
Note: Be sure you use the correct loads to upgrade. Your unit can lose all or part of  
its configuration if the wrong loads are used.  
Caution: Do not upgrade to an earlier software version. Newer units will not  
function properly when older software is loaded.

The Industry Canada label identifies certified equipment. This certification means  
that the equipment meets certain telecommunications network protective, operational,  
and safety requirements as prescribed in the appropriate Terminal Equipment  
Technical Requirements document(s). The Department does not guarantee that the  
equipment will operate to the users satisfaction.  
Before installing this equipment, users should make sure that it is permissible to be  
connected to the facilities of the local telecommunications company. An acceptable  
method of connection must be used to install the equipment. The customer should be  
aware that compliance with the above conditions may not prevent degradation of  
service in some situations.  
Repairs to certified equipment should be coordinated by a representative designated  
by the supplier. Any repairs or alterations made by the user to this equipment, or  
equipment malfunctions, may give the telecommunications company cause to request  
the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical ground connections of  
the power utility, telephone lines, and internal metallic water pipe system, if present,  
are connected together. This precaution may be particularly important in rural areas.  
Warning: Users should not attempt to make such connections themselves, but  
should contact the appropriate electric inspection authority, or electrician, as  
appropriate.
