Here is the example for GXW4232.

CONNECTING THE GATEWAY

  1. Connect a standard touch-tone analog telephone (or fax machine) to the FXS analog port on the front panel (GXW4248 has no FXS port, and it need 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 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.

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 password “admin” to configure the Gateway.

You will need the following information to configure the GXW42XX 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 use 50-pins RJ21 Telco Amphenol port as alternative interface (For GXW4248, telco port is mandatory) for connection to analog devices, such as analog telephone or fax machine.

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

Note:

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

Below is a picture of RJ11 female port patch panel.

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.
