2. If the ping is not returned, check the following parameters against the values listed on

3. If any of the above parameters do not match the site network plan, write the value using
the corresponding FIPS write command and reboot the RF-B! transmitter controller.
4. If all of the above parameters match the site network plan, there are a number of router
problems that will cause a disconnect, resulting in no data being transmitted to the RF-B!
transmitter controller:
Return Internet Protocol (RIP) is turned off on the external ethernet port.
Address Resolution Protocol (ARP) tables are corrupted.
Channel Service Unit-Data Service Unit (CSU-DSU) is not working [should say 56K
on the Liquid Crystal Display(LCD) CSU-DSU screen].
Frame Relay permanent virtual circuit (PVC) is not set up.
Cables or cable connections are bad.
Consult the router documentation for further explanation of the above. You may have to
reload the router configuration and reset the RF-B! transmitter controller to force
correction of the ARP tables. Do as much as possible to check the telco connections before
travelling to visit the site.
