EITHER PATH
Q: Is the router powered?
A: The Power Adaptor LED and router’s POWER LED should both be on.
If the Power LED is off when the Power Adaptor LED is off - the power source may be
faulty or if OK replace
the power adaptor or mains cable.
If the Power LED is off when the Power Adaptor LED is on - replace the router.
Q: Are all xDSL connections correct and are they working reliably?
A: If SYN & DAT indicators are off please check connectors are well seated. If
connections seem OK swap the filter, cables, or adaptors between the line socket
and router. Customer-provided telephone line extension leads or sockets faulty may
need to be checked and replaced.
Q: Is the xDSL path now OK?
A: The SYN indicator should be on and stable and the DAT indicator should be on but
flashing to show data is passing through the router.
If the SYN is on & DAT indicators are on but not flashing then contact CSL Technical
Support to confirm the router’s xDSL path has been restored.
If the SYN indicator is off - the router may have recently been powered up or
rebooted, wait a minute and recheck.
If the SYN indicator persistently drops out or begins flashing then the router may be
unable to sync or randomly re-syncing. If all checks have been made to remove any
connection problems then retest with a spare router, otherwise, contact the CSL
support who will arrange for an xDSL test.
Q: Is the router configured correctly?
A: The CONFIG LED should be on or off but not flashing. If the CONFIG LED is flashing
then contact the M2M Support Team who will arrange the download of the site-
specific configuration.
Q: Is the mobile radio path now OK?
A: Ideally, one or more signal-strength LEDs should be permanently on. If all Signal
Strength LEDs are off it indicates no signal is available. If the signal strength is
usually OK this could indicate there may be a local transmitter fault. Contact the CSL
Technical
Support if this is suspected.
