Product Description
The Adtran 1175407L2 module is an essential component for establishing external voice connectivity within the Adtran Total Access 750 and 850 platforms. It features four Foreign Exchange Office (FXO) ports, which are designed to interface directly with the Public Switched Telephone Network (PSTN) or analog lines provided by a telephone company's central office (CO). This allows the Adtran system to originate and receive calls from the external telephone network, effectively acting as a gateway for voice traffic. With the FXO ports, the module enables the Adtran system to connect to standard analog telephone lines, such as those used for POTS (Plain Old Telephone Service). This is critical for applications like direct inward dialing (DID) where external callers can reach specific extensions within the organization, or for providing outbound calling capabilities through the PSTN. The module ensures that the analog signals from the CO lines are properly managed and integrated into the Adtran chassis for routing and processing. This module is particularly useful in scenarios where a business needs to connect its internal communication system to the public telephone network for voice services. It supports various voice applications, including basic telephony, faxing, and modem connectivity over analog lines. The Adtran 1175407L2 is a key element for building flexible and robust voice solutions, allowing organizations to manage their external voice communications efficiently and reliably.
