OVERVIEW OF OPERATION
Simply put, POTTR is an analog telephone line (POTS line) monitor and reporter.
POTTR can detect if a phone line is working properly, disconnected, or
inoperable due to shorted or open line conditions. POTTR is valuable for any
installation that requires a working POTS line for safety use (911) or for vending
or security applications.
Network Reporting using SNMP
POTTR tests and records the POTS line status, and reports this information over
a standard Ethernet network using SNMP. Standard SNMP management
software can control and configure POTTR, so it fits easily into any managed
networked environment without any additional control software.
Powered by PoE
POTTR is completely powered by the Ethernet PoE connection. No external
power supply is required. Therefore you must have a proper configured PoE
network port in order to use POTTR.
If there is no available PoE Ethernet port, you may use a PoE Injector on the
Ethernet cable connection. POTTR works with any IEEE 802.3af compliant
injector.
Almost all powered Ethernet (PoE) switches and routers are IEEE
802.3af compliant, and will work seamlessly with POTTR.

CONFIGURING POTTR
PoE Ethernet

POTTR
RJ-11 RJ-45
POTTR should be configured for use with your Ethernet network so that it can be
properly identified by the SNMP management software. POTTR uses a static IP
address that is stored permanently in the unit. Other network variables, Netmask
& Gateway address, can be configured and saved as well.
The default network values for POTTR are listed below:
Device IP address = 192.168.1.200
•
Netmask value = 255.255.255.0
•
Gateway address = 192.168.1.1
•
Configuring Ethernet
Most likely you will need to configure the Ethernet interface values of POTTR in
order for it to work properly on your network. In order to configure POTTR, you
will need to attached it up to a private network that has a computer running
Telnet. See below:
Using the computer, open up a Telnet session to POTTR using the default values
previously listed (192.168.1.200). You will be prompted for the login credentials
for POTTR. Use the default values below:
Login: admin
•
Password: <MAC address of POTTR unit, hex characters lower case>
•
(ex. 00:11:aa:33:cc:55)
From here, you will be able to set the POTTR networking parameters. Once you
have completed the network configuration, you need to power cycle POTTR for
the new values to take affect.
Make sure you have programmed in the network values correctly. If
you make a mistake, try again to set the parameters correctly before
power cycling POTTR. Be sure to write down the new network
parameters! If you forget these values, you will need to reset POTTR

USING POTTR
POTTR communicates with standard SNMP and appears as a SNMP Agent on
the network. Any SNMP Manager application should be able to see and control
POTTR, as long as the Manager software knows the POTTR IP address on the
network.
SNMP Configuration
There is a MIB file available for your SNMP Manager application. Contact our
tech support department to get this file emailed to you :
techinfo@getpottr.com
MIB files are special device-specific files that tell the SNMP Manager
application what features and functions are available from a particular
SNMP device. They work with any SNMP Manager application.
POTTR Test Functions
POTTR performs two different tests on the POTS line to determine if it is
functioning correctly. It does a line voltage test and a off-hook dialtone test.
For a line voltage test, POTTR looks to make sure the line voltage
•
measures correctly for two different conditions, ON-hook busy and ONhook not busy.
The line voltage test occurs continuously at a settable time interval. The
•
default value is every 30 minutes.
For the dialtone test, POTTR goes off-hook briefly and listens for a
•
dialtone. This test is performed every time a line voltage test passes
and the line is not busy.
For all tests, the pass / fail values are programmable via SNMP, so you
•
may customize the test for your particular environment, though the
default values are already correctly set for standard POTS lines.
Reading POTTR Test Results
To quickly determine if the POTS lines are ok and functioning, you may do a
SNMP read (SNMPget) of two POTTR registers, 46610.3.3.0 and 46610.3.18.0.
These registers will reflect the current test status of POTTR. See the POTTR
Register table in the Appendix to interpret the results of these registers.

Test Pass
If the line voltage falls between lineBusyThresholdVolts (11v default) and
onHookMaxVolts (60v default), then the Line Voltage Test is considered OK and
a PASS is logged.
If the line voltage measures above onHookMaxVolts (60v default) or below
onHookMinVolts (1v default) the line is defective and a FAIL is logged.
Test Details - Line Voltage Test, Busy (46610.3.3.0)
If the line voltage falls between onHookMinVolts (1v default) and
lineBusyThresholdVolts (11v default), then the line is considered Busy and the
lineIsBusyFlag (46610.3.9.0) gets set. If the line is continuously busy past the
time interval set in maxLineBusyDuration (480 minutes default), then the line has
a possible short circuit and a FAIL_LINE_BUSY is logged.
When the line is being used for normal communications, the line will
test as Busy. Since most telephone lines are not used continuously for
8 hours (maxLineBusyDuration default), no fail conditions should be
logged.
Test Details - Line Dialtone Test (46610.3.18.0)
POTTR performs a dialtone test of the POTS line if the Line Voltage test Passes
and the line is not busy. For this test, POTTR goes off-hook briefly and listens for
a proper dialtone. If it detects a correct dialtone, then the line is considered OK
and a PASS is logged.
SNMP Testing of POTTR
POTTR contains several advanced testing parameters which are used internally
to report a simple PASS / FAIL status. Please refer to the POTTR register list,
which is in the Appendix of this manual for specific settings.

Resetting POTTR
If POTTR gets misconfigured or the configuration information (IP#, etc.) gets lost
such that you are unable to connect to it, you can reset POTTR back to the
factory default values by following the steps below:
1. Disconnect all cables from POTTR and open up the top of the unit.
2. Locate the Reset Jumper header pins as outlined below.
3. Attach a header shorting block to the Reset Jumper header pins.
4. Apply power to POTTR by attaching the PoE Ethernet cable.
5. Wait 20 seconds for POTTR to initialize.
6. Remove the PoE Ethernet cable and remove the Reset Jumper.
7. Re-install the POTTR top. POTTR will now be configured with the
factory default values.
