1 POTSwap General Description
The POTSwap allows landline telephones to replace their POTS (plain old telephone service) connection with a
wireless cellular connection. Both dial-in and dial-out data and voice applications are supported.
An FXS connection (RJ11 jack) provides complete Central Office emulation including dial tone, ringing and busy
signal generation as well as DTMF detection and generation. The POTSwap emulates all the functions of a wired
telephone connection, is fully compatible with all common modem standards and can be configured to emulate all
international telephone line standards.
Wireless connectivity is provided by the Janus line of Plug-In Terminus terminal modems which provide support for
all current mobile network technologies with service available from numerous wireless carriers.
Configuration of the POTSwap can be achieved via a local serial interface connection.
2 Plug-In Terminus
Cellular communication for the POTSwap is powered by Plug-In Terminus terminals. Plug-In Terminus offer easy
integration and interchangeability of communication protocols between GSM/GPRS, CDMA, UMTS, EVDO and more
by combining full M2M functionality with the flexibility of a standard “plug-in” DIP design. These terminals share
the same mechanical footprint and offer users the ability to configure their applications for communications via any
cellular protocol. The POTSwap provides one platform that supports current cellular technology with the future in
mind.

3 Operation
3.1 Set-Up:
Operating the POTSwap with voice (telephone) equipment can be achieved through the following steps:
1. Gather the required equipment:
• POTSwap
• Power Supply - This can be hard-wired from a user supplied power source via the terminal block header (See section 9 -
Compatible Terminal Block Connectors) or using the optional wall transformer (See section 10 - Accessories).
• Cellular antenna - A 2-band (‘dual-band’) CDMA cellular antenna is recommended. An optional cellular antenna is
available (See section 11 - Accessories).
• GPS antenna - On units equiped with a GPS antenna connector, a GPS antenna may be connected. (See section
11 - Acessories.)
• The POTSwap requires an activated cellular account with a cellular carrier (Verizon). You must provide the MEID
number of the POTSwap to the cellular carrier in order to establish an account. The MEID number is printed on
the POTSwap label, and is available through the IDENTIFY command from the terminal menu (see section 4 -
Configuration).
2. Connect a cellular antenna to the SMA connector labeled ‘CELLULAR’. This can be a local antenna or a
remote antenna connected by a coaxial cable. [Optional] Connect a GPS antenna to the SMA connector
labeled ‘GPS’. (See section 7 - GPS.)
3. Connect power to the unit.
Once powered, the unit should show a connection to the cellular carrier within a minute. This will be indicated
by a rapidly flashing GREEN ‘STATUS’ LED, a blinking ‘CELLULAR’ LED, and a steady signal strength
indication on the Received Signal Strength LED stack.
4. A POTSwap with a newly activated account with a cellular carrier must first be ‘provisioned’. This can be
accomplished by dialing *228 from a telephone device attached to the POTSwap (see section 6 - Provisioning).
3.2 Voice Operation
Voice operation requires a standard voice telephone device to be connected to the POTSwap.
3.2.1 Placing calls:
When the connected telephone device is taken off hook, the POTSwap will present an audio dial tone signal.
Dialing can proceed with up to 30 digits being accepted. If the Dialing Tone Timeout (30 second default) elapses
before the first digit is dialed, the dialing session is ended by an Open Switching Interval (900 millisecond default).
If the Dialing Digit Timeout (4 second default) elapses after a dialed digit, dialing is concluded and a call to the
dialed number is placed. At any time the number sign (‘#’) can be dialed and the call is placed immediatly,
avoiding the Dialing Digit Timeout. Note that if Fixed Format Dialing is enabled, the dialed number must consist of
a ten digit phone number that includes the area code, or an eleven number when the first digit is a ‘1’.
Firmware versions earlier than 150904 only allow dialing fixed format, 10 or 11 digit numbers.
The POTSwap CANNOT be used to dial 911.
Telephone devices that automatically take the phone off-hook and place a call to a fixed telephone number are
compatible with the POTSwap. Dialing digits should not be sent faster than 100 ms per digit, with a minimum
DTMF tone duration of 45 ms.
The POTSwap is compatible with DTMF dialing only. Pulse dialing will not work.

3 Operation continued
3.2 Voice Operation continued
3.2.2 Receiving calls:
Incoming calls will cause the POTSwap to generate a ringing signal on the phone line. Taking the connected
telephone line off-hook will answer the incoming call. Note that cellular carriers typically impose a 30 second limit
on unanswered ringing before a call is transferred to a voice mail system.
3.2.3 Call Disconnect:
A call can always be terminated by placing the connected telephone equipment on-hook. If a cellular call
is terminated on the carrier side (the result of a connected party ending the call or due to loss of signal) the
POTSwap will use an Open Switching Interval to aid in disconnecting automated type telephone equipment. It
removes the voltage from the phone line connection for a short time to signal that the call has been terminated.
The OSI interval can be adjusted using the user configuration menu.
3.2.4 Unconnected Busy:
In some instances when dialing a number that is busy, the cellular carriers will not make an audio connection
to a busy tone. If this occurs, the POTSwap will generate the busy tone locally for a period defined by the user
configurable Busy Dwell Timeout parameter. Following the busy tone, the POTSwap will terminate the call by
generating an Open Switching Interval (see section 4 - Configuration).

4 Configuration
Configuration of the POTSwap is available via communications with the SERIAL PORT connection. Configuration can
be accomplished by connecting a DTE terminal device (e.g. laptop or desktop computer running a terminal emulator)
to the SERIAL PORT using a straight-thru DB9 serial cable (DB9-M to DB9-F). Newer computers may require a USB
to serial port adaptor to complete the connection.
Figure 3 Serial Connection
Default communications protocol is 115200 baud, 8-N-1 (8 data bits, no parity, 1 stop bit) with no handshaking.
When the POTSwap is first powered on, it will output something similar to the following:

6 Provisioning
A new POTSwap (model EVDO910PS) will require provisioning by the cellular carrier before it can be used.
Provisioning occurs ‘over the air’ and sets up the cellular radio in the POTSwap to operate on the carrier’s network.
The phone number of the cellular radio is installed during provisioning.
When negotiating a service agreement with a cellular carrier, the MEID (Mobile Equipment IDentifier) of the POTSwap
cellular radio will be required. This 14 character code can be found on the label on the top of the POTSwap
enclosure. It can also be obtained using the ‘IDENTIFY’ command from the terminal configuration menu. See
section 4 - Configuration.
Provisioning can be performed by dialing *228 from a connected telephone device or from the terminal configuration
menu by entering the ‘PROVISION’ command. A signal strength indication of 3 or 4 LED ‘bars’ is recommended.
When provisioning using the *228 dialing option, a dial tone must be present before dialing. During provisioning, the
cellular carrier will provide an audio message about the success or failure of the provisioning process.
When provisioning using the ‘PROVISION’ command from the terminal configuration menu, the procedure can be
monitored by observing the output to the terminal. “Provisioning failed” will be reported if the provisioning was not
successful. Following provisioning using the terminal configuration menu, enter the REBOOT command restart the unit.

POTSwap models HSPA910PS V1.00 TAGFNG and EVDO910PS V3.00 TAGFNG have a GPS antenna connector
installed on the back plate and offer the ability to provide enhanced location information to emergency (911) operators.
A suitable GPS antenna must be used and the antenna must be properly located to receive the GPS signals.
The GPS operation is automatic, and is independent of the cellular radio operation. When the unit has acquired a
GPS location fix, the bottom LED on the RSSI indicator will blink several times for 1 second at 10 second intervals.
This indication is independent of the cellular signal strength indication. See section 5.1 – Front Panel. A GPS
location fix should be available within a few minutes of operation under normal conditions.
7.2 GPS Antenna
For best results, it is recommended that an active GPS antenna be used with the POTSwap. The GPS antenna
connector provides a 2.85V bias voltage to power an active antenna, and should easily be able to supply the 5 to
25mA of current that a typical active GPS antenna requires. Any standard off-the-shelf active GPS antenna that will
operate at the 2.85V bias voltage should suffice. See section 11 – Accessories.
7.3 GPS Antenna location
The ideal GPS antenna position would be an outdoors location with a clear view of the sky to the horizon in all
directions, with no obstructing structures or foliage. A higher antenna placement usually gives a better view of the
sky over surrounding obstructions. In the northern hemisphere, a southern sky view is preferable over a northern sky
view. If the antenna must be indoors, placement as near as possible to a window is preferable. Receiving a GPS
location fix deep inside buildings or in dense urban environments (“street canyons”) is normally not possible.
7.4 GPS Troubleshooting
With a terminal attached to the SERIAL port, debug messages are available that can be used to monitor the GPS
operation. See section 4 – Configuration, for information on attaching a terminal to the SERIAL port.
There are several types of debug messages output during normal operation. The message with the GPS information
includes “$GPSACP:” near the beginning of the output line, and is output about once per minute. The $GPSACP
message conveys 11 terms, separated by commas:
UTC UTC time (hhmmss.sss)
latitude format is ddmm.mmmm N/S
longitude format is ddmm.mmmm E/W
hdop x.x - Horizontal Diluition of Precision
altitude x.x Altitude - mean-sea-level (geoid) in meters
x 0 or 1 - Invalid Fix; 2 - 2D x; 3 - 3D x
cog ddd.mm - Course over Ground (degrees, True)
spkm x.x Speed over ground (Km/hr)
spkn x.x- Speed over ground (knots)
date ddmmyy Date of Fix.
nsat nn - Total number of satellites in use, 00..12
The final term can be used to provide some useful information about the quality of the GPS antenna system being
used. Generally, the better the antenna system, the greater the number of satellites will appear in the ‘nsat’ term.
Though it varies over time, the typical maximum number of satellites available is 10. A minimum of 4 is required to
get a location fix, and numbers of 8 or more indicate an excellent antenna system.
With no location fix, the $GPSACP message will appear as follows:
[$GPSACP: ,,,,,1,,,,,]
This would be expected after the unit has powered up but before a location fix is aquired. It would also be indicative
of a poor antenna system if it was still being reported after several minutes of operation.
A typical fix might appear similar to the following:
[$GPSACP: 183117.000,4147.6251N,08815.5097W,1.25,191.0,3,191.69,0.12,0.06,290716,07]
In this example the ‘nsat’ term indicates that 7 satellites are being used.
