CONNECTING THE GXW42XX V2 SERIES

Refer to the illustration below when following the instructions.

Here is the example for GXW4232 V2.

CONNECTING THE GATEWAY

  1. Connect a standard touch-tone analog telephone (or fax machine) to the FXS analog port on the front panel (GXW4248 V2 has no FXS port, and it needs to use the telco cable to connect the RJ21 port on its back panel, see section “Telecom Port Installation “ for details).
  2. Insert the Ethernet cable into the LAN port of GXW42XX V2 and connect the other end of the Ethernet cable to an uplink port (a router, a modem, etc.).
  3. Using the embedded web server or IVR (Interactive Voice Prompt) menu, you can further configure the gateway using either a static IP or DHCP.

GXW42XX V2 CONFIGURATION

Configure using Interactive Voice Prompt

From the analog phone, press *** to get into the IVR menu. Follow the voice instruction, and configure the setting.

Configure using embedded Web server

  1. From the analog phone, press *** to get into the IVR menu. Enter option 002 to obtain the Gateway’s IP address.
  2. Type the device’s IP address in your PC browser.
  3. Log in using the password printed on the label to configure the gateway.

You will need the following information to configure the GXW42XX V2 series via the web browser:

  • IP address, subnet mask, and gateway IP if using static IP.
  • Each SIP server and/or Outbound Proxy FQDN or IP address for one Profile (4 in total).
  • User subscriber information: User ID, Authentication ID, Password under FXS port label.
  • Please contact your ITSP for additional settings that may be necessary to configure the device.

TELECOM PORT INSTALLATION

GXW42XX V2 uses a 50-pin RJ21 Telco Amphenol port as an alternative interface (For GXW4248 V2, the telco port is mandatory) for connection to analog devices, such as analog telephones or fax machines.

When installing the telco port, a common RJ21 Telco Amphenol 50 pin 25 pair cable is needed (included in the GXW4248 V2 package only). You can connect the cable to an RJ11 patch panel, which could provide better cable management in most scenarios.

Note:

Only GXW4248 V2 package has telco cable included, and telco cable header will be RJ21 to 25 blunt pairs.

Below is a picture of an RJ11 female port patch panel.

The following table shows the correspondent relation between the No. of each Telco cable’s RJ11 crystal head and the real FXS port number of GXW42XX V2.

Note:

Row “Right” indicates the righthand side telco port, when you facing the back panel of GXW42XX V2, and “Left” is the left telco port.

The GXW42XX V2 Series is not pre-configured to support or carry emergency calls to any type of hospital, law enforcement agency, medical care unit (“Emergency Service(s)”) or any other kind of Emergency Service. You must make additional arrangements to access Emergency Services. It is Your responsibility to purchase SIP-compliant Internet telephone service, properly configure the GXW42XX V2 series to use that service, and periodically test your configuration to confirm that it works as You expect. If You do not do so, it is Your responsibility to purchase traditional wireless or landline telephone services to access Emergency Services.
