Terratel SFP-E1 module is designed to integrate and connect IP-PBX, IVR systems, VoIP-gateways, other specialized solutions of the Asterisk project or FreeSwitch to office PBXs, as well as the public telephone network PSTN via the E1 interface.
Digital SFP-E1 module is designed to build digital telephony systems based on Asterisk IP-PBX and exchanges data/voice over E1 channels.
The new SFP-E1 module is the latest addition to the D-201E/D-401E digital phone card family for the Asterisk project.
The SFP-E1 module design uses unique technologies to support the E1/PRI environment. The SFP-E1 module is designed to connect traditional TDM systems with voice over IP technologies in a single network.
The SFP-E1 module is installed in the sfp-slot of network equipment, which allows it to be used in any place where the network is available, and not just at the location of the Asterisk server.
The SFP-E1 digital module is compatible with all Asterisk versions and connects to Asterisk using a special DAHDI-enabled driver. A special driver with DAHDI support is available for free on the terratel.eu website.
The SFP-E1 module has a hardware echo cancellation function for all voice channels of the E1 stream.
