3. If the 1600 DSL module still does not work properly, go to Possible Cause 4.
Possible Cause 4: The LAN connection is not established. The network connection of the 1600
DSL module can be checked by "standard" network troubleshooting tools. Lack of network
connectivity can result in two problems: no data connectivity to the internet and/or no voice
communications when a Pathstar gateway is used.
What to do: Follow these steps to check the LAN connection:
1. From the PC or PCs that are experiencing difficulty, ping the LAN interface on the 1600 DSL
module. If this fails check the following:
IP address and netmask on the PC and 1600 DSL module. Make sure they are on the
I
same subnet.
Verify that the Ethernet status/activity LEDs are lit on the PC, hub (if used), and 1600 DSL
I
module. If the LEDs are not lit, check the type (standard or crossover) and condition of the
Ethernet cables used to connect the various devices.
2. Ping the SDSL IP address (the PVC/DLCI associated with data) of the router. If this fails
recheck that the address is what you programmed into the 1600 DSL module.
3. Ping the gateway address that is programmed into the 1600 DSL module router. This address
is the router that is at the other "end" of the data PVC/DLCI that is situated at the ISP. If this
fails, confirm the following:
Has the gateway been programmed into the 1600 DSL module? From the Main Menu,
I
press "2," "s," and "f." If the default value is what was provided by the service provider/ISP,
press Enter.
Verify the address of the router and the PVC/DLCI associated with the data connection
I
from the service provider/ISP.
4. If the customer is experiencing problems loading webpages from a browser, ping the DNS
servers that the service provider/ISP has provided. If this fails, confirm with the service
provider/ISP the DNS IP addresses.
5. If there is no voice when a Pathstar gateway is used, do the following:
a. Verify the MGCP/NCS setting. There should be at least two (2) distinct addresses:
The "local" IP address of the voice PVC/DLCI interface on the SDSL port
I
The address of the Pathstar gateway
I
b. Verify the PVC/DLCI settings that the service provider has configured for the voice
connection.
