EZLoop® PSTN Gateway FXO2/FXO4/FXO6 behaves as a
bridge between local PSTN and IP network for voice and
FAX services. The PSTN Gateway transports voice and FAX
services between PSTN and IP network without any distortion.

The EZLoop® PSTN Gateway FXO2/FXO4/FXO6 provides voice
and fax services over IP network with H.323 v3 or SIP RFC3261 protocol. By connecting with your existing ADSL or cable Modem service, this allows the use of a single network for voice and fax services and reduced telephone charges.

The EZLoop® PSTN Gateway is an ideal solution for providing
low cost communications between headquarters and branch offices in the world, as well as for SOHO and office telephony applications.

The EZLoop® PSTN Gateway FXO2/FXO4/FXO6 provides up
to six (6) FXO ports connecting to local PSTN. It is an interface
to access PSTN with IP-PBX solution. A 10Base -T interface
connects local Ethernet network with IP Phone and H.323 Gatekeeper or Call Manager. The data and voice services
are working in a local Ethernet network. The TOS setting
of EZLoop® PSTN Gateway FXO2/FXO4/FXO6 provides
voice priority in IP network.

Using two wire loop start Foreign Exchange Office (FXO) interfaces, EZLoop® PSTN Gateway FXO2/FXO4/FXO6 convert packetized Voice and FAX to local circuit switching PSTN network. It also converts the voice and fax traffic to IP network
with packetized form. The packetized data is sent via an Ethernet connection to IP network.

EZLoop® PSTN Gateway FXO2/FXO4/FXO6 provides management features for system Configuration, Debug and
Maintenance via RS-232C COM port and TELNET. TELNET/Web and COM port interface provide local / remote
configuration, Management and software download. By using this feature, for ITSP/ISP provides centralized
control to remote sites.
