Unable to program an ETP-400, ETP-500, or ETP-520 when connected to an ETP-CI-4G-V or ETP-CI-4G-GSM

Unable to program an ETP-400, ETP-500, or ETP-520 when connected to an ETP-CI-4G-V or ETP-CI-4G-GSM

Accessing configuration

Configuration of the ETP-CI-4G-V or ETP-CI-4G-GSM is available via communications with the CONFIG USB connection. Configuration can be accomplished by connecting a terminal device (e.g. laptop or desktop computer running a terminal emulator) to the CONFIG port using a USB cable with a USB ‘mini’ type B connector for the ETP-CI-4G-V or ETP-CI-4G-GSM. The USB connection requires a CP210x USB to UART Bridge VCP Driver. Normally this will be automatically installed by the operating system. Otherwise it can be downloaded from Silicon Laboratories at www.silabs.com.

Serial interface settings for the CONFIG port are
Speed: 115200 baud
data bits: 8
parity None
Stop Bits: 1

When the ETP-CI-4G-V or ETP-CI-4G-GSM is first powered on, it will output something similar to the following:
WireLine III Board - POTSwap - [FIRMWARE VERSION]
12.288MHz Codec Build
LE910 Power-Up Mode

WireLine_Open
      900 Open Switching Interval
      30000 Dialing Tone Timeout
      4000 Dialing Digit Timeout
      6000 Busy Dwell Timeout
      0 Fixed Format Dialing
      0 Fail Over Mode
      30 VoLTE DTMF Duration
      6 VoLTE DTMF Volume
      4 Inbound Audio Gain
      4 Outbound Audio Gain
      0 SMS Alert Period
      
The first line will contain the version number of the firmware in a YYMMDD (year, month, day) format. Following this are the current configuration settings. Several of these parameters are user configurable and can be adjusted by entering the CONFIG command during the power-up sequence. About 30 seconds following the application of power, the unit offers a short interval wherein the user can enter the terminal configuration menu. The following text will be output:

WireLine III Board - POTSwap
Entering Terminal Mode, 10 seconds to type first command
Type ? for help, Q to exit
FW: HH:MM:SS MTH DY YEAR
READY

After ‘READY’ is output the user has 10 seconds to enter one of the following commands followed by a line termination (‘Enter’ key on PC’s):

These commands are NOT case sensitive. Terminal menu commands operate as follows:
?, H: Entering a ‘?’ or ‘H’ character will output the Terminal menu command menu again. It can be useful if the menu has scrolled off of a screen.
Q ,QUIT: Entering ‘Q’ or ‘QUIT’ will exit the DEBUG menu and continue with the normal start-up and operation of the POTSwap.
XMODEM: Used for firmware upgrades.
REBOOT: Entering ‘REBOOT’ will restart the POTSwap, similar to pressing the RESET button.
CONFIG: Entering ’CONFIG’ will cause the configuration menu to be output
IDENTIFY: Displays the phone # and IMEI number of the cellular radio.  

Commands and Descriptions

The configuration menu lists the name of the parameter, the current setting (in brackets), and the range or values of settings available. These settings may vary depending on the model of Plug-In Terminus terminal used in the ETP-CI-4G-V or ETP-CI-4G-GSM. Following the list of parameters are options for changing the configuration settings or leaving this menu: M, D, X, and Q. These single character command options can be entered in upper or lower case, and no enter key is required.

M - Modify Commands:

Entering an 'M' command will cause the current setting for each parameter to be output, and allows changing the parameter setting. Currently, the following parameters can be modified:
Parameter
Default
Range
Function
Open Switching Interval
900 (milliseconds)
0-1200 (milliseconds)
Sets the period that the battery voltage is removed from the telephone line following the termination of a call from the carrier side, a dialing timeout, or a locally generated busy tone. (AKA Kewlstart.)
Dialing Tone Time-out
30000 (milliseconds)
500-60000 (milliseconds)
Sets time limit for first dialing digit to be entered following going off-hook. Exceeding the time limit will cause Open Switching Interval to be generated.
Dialing Digit Time-out
6000 (milliseconds)
250-15000(milliseconds)
Sets time limit for time between entering dialing digits. Exceeding the time limit will cause Open Switching Interval to be generated.
Busy Dwell Timeout
6000 (milliseconds)
1000-30000 (milliseconds)
Sets length of time a busy tone is generated locally on calls where the cellular carrier does not provide an audio connection to a busy tone. The Open Switching Interval will be generated following the busy tone
Fixed Format Dialing
0
0-1
Enables Fixed Format dialing. When set to ‘1’ (enabled), only 10 digit (or 11 digits when first digit is a ‘1’) dialing and 911 dialing is allowed. When set to ‘0’ (disabled), any number of dialed digits is accepted once the Dialing Digit Time-out is exceeded. Dialing the number sign (‘#’) short-cuts the Dialing Digit Time-out and immediately accepts the dialed digits
Fail Over
0
0-2
Dial tone availability: 0 - Any network availability, including emergency (911) ONLY. 1 - Home network registration 2 - Home or Roaming registration
VoLTE DTMF Duration
30
0-255
Sets inbound DTMF tone duration in cases where network uses OOB (out-of-band) DTMF signaling. 10ms increments, so range of 0 (OFF) to 255 (2.5 seconds). ( These commands are available on firmware shipped after July of 2022.)
VoLTE DTMF Volume
6
1-10
Sets inbound DTMF tone volume in cases where network uses OOB (out-of-band) DTMF signaling. Does not affect audio (voice) volume ( These commands are available on firmware shipped after July of 2022.)
Inbound Audio Gain
4
1-16
Sets inbound audio gain
Outbound Audio Gain
4
1-16
Sets outbound audio gain
SMS Alert Period


Phone numbers to which SMS alert messages will be sent. Enter 10 digit phone numbers with no spaces or dashes. Multiple numbers can be separated by commas or semicolons. (These commands are available on firmware shipped after July of 2022. If you have SMS enabled on a SIM card plan, you may incur additional fees from spam messages. Carriers can only enable or disable SMS service, they cannot provide plans that limit SMS to outbound messages only. SIM card plans offered by Janus for the POTSwap disable SMS)
APN
broadband (V1.00)
vzwinternet (V3.00)

Sets APN (Access Point Name).

D - Defaults Command:
Entering the ‘D’ command will change all of the settings back to the factory defaults. These settings will not be saved unless the ‘X’ Exit and Save command is issued. Older versions of firmware will request that the POTSwap be restarted to effect the changes; current versions will restart automatically.

X - Exit and Save Command:
Entering the ‘X’ command will save any changes made using the ’M’ Modify or ‘D’ Defaults commands. This will also exit the menu system and requires that the POTSwap be restarted either by pressing the RESET push button or by un-powering and re-powering the unit.

Q - Quit and Discard Command:
Entering the ‘Q’ command will discard any changes made using the ’M’ Modify or ‘D’ Defaults commands. This will also exit the menu system and requires that the POTSwap be restarted either by pressing the RESET push button or by un-powering and re-powering the unit.

Adjusting the VoLTE DTMF Volume

  1. Follow the steps outlined above for accessing the configuration.
  2. At the Configuration command menu enter 'M' for modify. The device will show the first variable value.
  3. Press the 'Enter' key unto you reach 'VoLTE DTMF Volume', then enter the new value.  It is recommended to be at least 6.
  4. Press the 'Enter' key unto you reach the end of the menu, then enter 'X' for Exit and Save.
  5. The device should reboot.

If 'VoLTE DTMF Volume' is not one of the available options then the device is running an older firmware and should be updated.
