Network connection not working when using Telnet & File Transfer
Protocol (FXS, FXO and E&M/E&M-OD)
Symptom
:
Cannot communicate with unit through a Telnet/FTP connection.
Cause
:
The power to the unit is not turned ON. Also, the unit IP address
is incorrect and/or the computer and unit are not configured as
members of the same domain (Gateway and subnet addresses.)
Finally, if communicating across a firewall, the Telnet/FTP
requests the Firewall restrictions parameter is not selected.
Action
:
Turn the unit’s power ON. Also, check the IP addressing scheme
for the computer host settings and the unit and correct them if
necessary. See BV1250 Installation Guide, Section 5.7, for
details.
Finally, if a firewall is present, configure the Telent/FTP requests
for Firewall restrictions. See BV1250 Installation Guide,
Appendix G for details.
Outgoing calls okay, but incoming calls are restricted (FXS, FXO and
E&M/E&M-OD)
Symptom
:
Units connected to the network through an Ethernet switch using
an ARP cache outgoing calls can be placed but cannot receive
incoming calls.
Cause
:
If an Ethernet switch using an ARP cache is configured with a
refresh rate that is shorter than that of the routers used to connect
network workgroups, the switch may not be able to accept the
incoming data and forward it to the correct node.
2
Action
:
Reconfigure the Ethernet switch ARP cache table refresh rate so
that it is longer than the router ARP table refresh rate. See the
Router’s documentation for details.
Unit installed a far end of network cannot make or receive calls (FXS, FXO
and E&M/E&M-OD)
Symptom
:
Even after checking all cabling and network connectivity, it is not
possible to setup calls. The problem unit is located on a branch at
the far end of the network.
Cause
:
The unit’s gateway address represents the network’s main router,
but there is another router that is closer.
Action
:
Change the unit’s gateway address to that of the router that is
closest to the unit. See BV1250 Installation Guide, Appendix G,
for details.

This conditions will not occur if a hub is used as the connection point for BV1250 units.
