CONNECTING THE GXW42XX Series
Refer to the illustration below when following the instructions on the next page.
CONNECTING THE GATEWAY
- Connect a standard touch-tone analog telephone (or fax machine) to the FXS analog port on the front panel. Note: The GXW4248 does not have individual FXS ports on the front panel; instead, it uses female RJ21 Telco (Amphenol) connectors on the rear panel. Use the included male RJ21 Telco cable to connect the gateway to analog devices or a patch panel. For more details, see section “Telecom Port Installation.
- 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.).
- Using the embedded web server or IVR (Interactive Voice Prompt) menu, you can further configure the gateway using either a static IP or DHCP.

TELECOM PORT INSTALLATION
GXW42XX uses a 50-pin female RJ21 Telco (Amphenol) port as an alternative interface (for GXW4248, the Telco port is mandatory) for connecting analog devices such as telephones or fax machines.
When installing the Telco port, a standard male RJ21 Telco Amphenol 50-pin 25-pair cable is required (included with the GXW4248 package only). The cable can be connected to an RJ11 patch panel, which helps organize wiring in most installation scenarios.
Only the GXW4248 package includes two Telco cables, each featuring a male RJ21 (50-pin) to 25 blunt pair header for direct connection to analog lines.
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.
