1. Product Introduction
1.1 General Information
FXS Series Gateway are the performance Gateway, which developed by DBL Co. FXS
Series gateways built-in H.323 and SIP protocols. Highly reliable line detection prevents
the line hanging death in the largest tent. Convenient and practical function of a broken
network escape, when disconnect the network, or VOIP logon fails, FXS to mention the
opportunity to jump directly to the outside PSTN. It can forward outside Caller ID
Number under the SIP protocol, which is an important function of PBX application. Super
Echo Cancellation Algorithm and Balanced Circuit make line echo minimum. Low price,
Stable and performance are pronoun of the FXS Series products，it is the first choice of
PXS Manufacturers, Call Center and System Integrators.

C) The default IP address and mask of the PC port are 192.168.8.1 and
255.255.255.0 respectively.
Connect the computer with the PC port of the gateway through the IP address
of the PC port, and set the IP of the computer to dynamic IP or fixed IP as
192.168.8.xxx and the default gateway as 192.168.8.1.
