DIAGNOSTICS
The Diagnostics menu provides feedback on the connection status of the
CPVA500 and the ADSL link. A description of each test can be obtained by
clicking on the help button associated with the test.
Without an active ADSL connection, many of the tests will not be activated, and
when the current network operating mode is in bridge, the default gateway and
DNS server tests will not be activated.
There are two buttons at the bottom of the screen:
Rerun Diagnostic Tests
Rerun Diagnostic Tests With OAM F4
When either of the Rerun Diagnostic Tests buttons are pressed, all the
diagnostic tests are repeated. Normally, if one or more tests return a failure
status, the user should rerun all the tests again to more thoroughly diagnose
the problems encountered.
When Rerun Diagnostic Tests With OAM F4 is pressed, ATM OAM F4 loopback
cells are also transmitted, in addition to OAM F5 cells. It is possible that the
ATM OAM F4 loopback or segment tests may not be supported by the ATM
devices in the DSL service provider's network. For this reason, the OAM F4 test
is separated from the general diagnostics tests. When an OAM F4 failure is
encountered, the output screen will appear as an F4 Fail.

The following figure shows an example of diagnostics page, when the PVC is
configured in MER mode.
The following table provides a brief description of each diagnostics test.
Tab. 15: Diagnostics test description
Test
Description
Ethernet Connection
Pass
: Indicates that the Ethernet interface from
your computer is connected to the LAN port of your
DSL Router. A flashing or solid green LAN LED on
the router also signifies that an Ethernet connection
is present and that this test is successful.
Fail
: Indicates that the DSL Router does not detect
the Ethernet interface on your computer.
USB Connection
Pass
: Indicates that the USB interface from your
computer is connected to the LAN port of your DSL
Router.
Down
: Indicates that the DSL Router does not
detect the USB interface on your computer.
ADSL Synchronization
Pass
: Indicates that the DSL modem has detected
a DSL signal from the telephone company. A solid
DSL LED on the modem also indicates the detection
of a DSL signal from the telephone company.
Fail
: Indicates that the DSL modem does not detect
a signal from the telephone company's DSL
network. The DSL LED will continue to flash green.

ATM OAM Segment Ping
The modem transmits OAM F4/F5 (if you rerun the test
with OAM F4, both F4 and F5 are sent, otherwise only
F5 is sent) segment loopback requests and expects a
reply within 5 seconds. This test verifies that ATM
continuity exists between the virtual channel link
segment from the modem to the DSL provider network
(typically this is a DSLAM at the DSL provider site).
Pass: Indicates that the DSL modem can
communicate with the DSL provider network.
Fail: Indicates that the DSL modem may not be able
to communicate with the DSL provider network.
This test may have an effect on your Internet
connection. Occasionally the DSL provider network
may intentionally block this traffic. Therefore if this
test fails, but you are still able to access the
Internet, there is no need to troubleshoot this issue.
ATM OAM end-to-end Ping
The modem transmits OAM F4/F5 (if you rerun the test
with OAM F4, both F4 and F5 are sent, otherwise only
F5 is sent) end to end loopback requests and expects a
reply within 5 seconds. This test verifies ATM
connectivity of the virtual channel link with the ATM
PVC endpoint, such as a remote broadband access
router located at the DSL provider or ISP site.
Pass
: Indicates that the DSL modem can
communicate with the DSL provider network.
Fail
: Indicates that the DSL modem may not be
able to communicate with the DSL provider
network. Occasionally the DSL network provider
may intentionally block this traffic. Therefore if this
test fails, but you are still able to access the
Internet, there is no need to troubleshoot this issue.
PPP Server
For PPPoA operating mode, the modem checks if PPP
(LCP and IPCP) are connected to the remote PPP
server. For PPPoE operating mode, this test verifies
that the modem can detect a PPPoE server by checking
if it can receive a PADO (PPPoE Active Discovery Offer)
packet from a PPPoE server after sending a PADI
(PPPoE Active Discovery Initiation) broadcast packet.
Pass
: Indicates that the DSL modem has
discovered a PPPoE server or can connect to a
PPPoA server.
Fail
: Indicates that the DSL modem failed to
discover a PPPoE server or connect to a PPPoA
server.
A
flashing green
PPP LED on the modem signifies
an attempt to establish a PPP connection.

Authentication with ISP
Verifies that the provided PPP username and password
stored in the DSL modem have been authenticated by
the PPP server within the ISP network.
Pass
: Indicates that your username and password
stored in the DSL modem has authenticated with
the ISP's network.
Fail
: Indicates that the PPP username and
password were rejected by the PPP server at the ISP
site. Either the PPP user name or password were
configured incorrectly, or the user account has not
been properly established at the ISP. The user
should re-enter the PPP user name and password
and retry. If a failure condition persists, contact the
ISP support.
Assigned IP Address
Verifies that the DSL modem has a valid IP address
(here, a PPP WAN IP address) from the PPP server.
Pass
: Indicates that the DSL modem has a valid IP
address from the PPP server.
Fail
: Indicates that the DSL modem does not have
a valid IP address from the PPP server.
Ping Default Gateway
Pass
: Indicates that the DSL modem can
communicate with the initial network entry point.
This is usually the IP address of the ISP router.
Fail
: Indicates that the DSL modem was unable to
communicate with the initial network entry point.
Ping Primary Domain Name
Server
Verifies that the DSL modem can communicate with
the primary domain name server (DNS).
Pass
: Indicates that the DSL modem can
communicate with the primary DNS.
Fail
: Indicates that the DSL modem was unable to
communicate with the primary DNS.

MANAGEMENT
In this menu it is possible to configure:
Settings (Provisioning, Backup, Update, Restore Default)
System Log
Access Control
Update Software
Save/Reboot
Provisioning
For large-scale networks, you can use a TFTP server to download a
configuration for each CPVA500. The TFTP server's URL and file name can be
provided (provisioned) from the DHCP server or can be configured via Web
page or Telnet/CLI. At the moment it is possible to configure the equipments
through TFTP about the VoIP functionalities.
In this mode of provisioning, at power-up, CPVA500 contacts the TFTP server
for a specific profile to download. If CPVA500 does not reach the TFTP server
after 30 attempts, it continues normal operation by using its locally cached
profile.
It is possible to configure a cfginterval (time in second). At cfginterval CPVA500
attempts to refresh its profile from the TFTP server.
CPVA500 updates the configuration file with frequency defined by cfginterval.
If any relevant parameter has changed, CPVA500 will be rebooted.
The default filename will have the following format: tlsxxxxxxxxxxxx, where
xxxxxxxxxxxx represents MAC address. The default cfginterval is 3600. The
default TFTP server's is 192.168.1.100.
If auto provisioning is configure in dynamic mode, TFTP server is mandatory
(default is not applicable).
In the filename is possible to configure the voice parameters.
The automatic configuration can be configured via Web page or via Telnet/CLI.
Example of configuration file via TFTP
For futher information regarding CLI command, please refer to CLI Chapter.
