The Fibramérica 4-Port FXS VoIP Gateway connects analog telephone equipment to a compatible IP voice platform. Four FXS ports provide access for phones or fax equipment in small offices, branch locations and distributed business installations.
SIP and H.248 support allow the gateway to work with a configured IP PBX or operator IMS/NGN platform. Four Gigabit Ethernet ports provide network interfaces, while the compact metal enclosure measures 212 × 149 × 26 mm.
The gateway supports common voice codecs, echo cancellation and T.30/T.38 fax protocols. Calling features are configured with the selected platform. Services such as wake-up calls, abbreviated dialing and do not disturb depend on the capabilities of the IP PBX or IMS system.
Local switching can support calls between extensions connected to the same gateway during an external-link interruption, subject to configuration. External calling depends on the availability of the network and voice service.
Routing and bridging modes, IP access options and traffic-priority controls support integration into an existing network. Configuration and monitoring options include a local web interface, SNMP, TR-069 and Syslog.
The gateway adds dedicated analog telephone access to a building network. It can complement Fibramérica FTTO & FTTR Systems when the project requires separate voice equipment. The network design determines whether a separate gateway is needed, since some access gateways already include FXS ports.
For installations requiring more analog telephone interfaces, explore the Fibramérica 8-Port FXS VoIP Gateway. Select the capacity according to the number of endpoints and the project configuration.
Specify the analog endpoints, voice platform, network arrangement and installation requirements. The quotation confirms the power input, adapter specification, service integration and any platform or licensing requirements.

The four FXS ports provide analog telephone interfaces for compatible phones or fax equipment. The connected endpoints use the configured IP voice platform. Four ports describe the physical analog capacity; service accounts, trunks and calling entitlements are defined with the selected platform.
Normal external calling requires a compatible IP PBX or operator voice platform and the appropriate service configuration. The gateway supports SIP and H.248 access. PBX software, service subscriptions and platform licenses are specified separately in the quotation.
The gateway connects to the IP network through Ethernet. The selected access equipment handles optical transport and termination. It can complement an FTTO/FTTR project or work with an existing Ethernet network when dedicated analog telephone ports are needed.
Equipment selection depends on the project. Some access gateways already include FXS ports. A separate voice gateway is selected when its port capacity, location or role is needed in the telephone network design.
The gateway lists T.30 and T.38 fax support. Fax operation must be checked with the fax model, IP network, provider and voice-platform configuration before deployment.
The gateway supports calling features such as caller ID, waiting, hold, forwarding and three-way calling according to the configured service. Functions such as wake-up/alarm services, abbreviated dialing or do not disturb require support from the selected IP PBX or IMS platform. Integration and licensing are defined for the project.
Configured local switching can allow calls between extensions connected to the same gateway. Calls outside the gateway depend on the availability of the external network and voice service. This feature does not establish a guarantee of uninterrupted external calling.
The listed power consumption is 15 W. The exact input rating and adapter specification must be confirmed for the supplied configuration in the quotation.
Provide the number and type of analog endpoints, the IP PBX or voice-service platform, network arrangement, installation country and any fax or hotel-service requirements. Fibramérica can then define the gateway configuration, power arrangement and integration scope.
Our engineering team can confirm compatibility, custom specs and OEM branding options.
