The Zed-3 GA90 modular gateway is a stand alone gate¬way for VoIP and PSTN. It converts the format of a phone call to allow it to pass between these networks.
The GA90 modular gateway comes with four modular slots; each can be used with an 8 port FXS card, an 8 port FXO card, or a T1/E1 card. This ensures the GA90 modular gateway can be fully connected to the PSTN.
The GA90 modular gateway is designed to connect to Internet telephony service providers (ITSPs) and any VoIP telephone systems using SIP. You will save money on making phone calls because of the low rates offered by ITSPs or creating toll by-passes among offices. You will also save money on infrastructure because the GA90 modular gateway can be easily integrated into your exist¬ing network.
The GA90 modular gateway can be mounted in a 19” rack and has four slots into which you can plug any interface module: 8 port FXS module, 8 port FXO module, and one port T1/E1 module.
The FXS port can connect to analog telephones or to a PBX (in which case, it appears as the telephone ex¬change). The FXO port connects as a subscriber to your PBX or to the telephone exchange. The T1/E1 port con¬nects as user side to the telephone exchange or network side to other equipment.
There are two working modes in which the GA90 modu¬lar gateway connects with other SIP devices, including interconnection with other GA90 modular gateways.
The basic working mode is similar to that of a SIP phone in which the GA90 modular gateway registers to another SIP device, such as a soft switch or IP PBX.
The second working mode is to connect to other SIP devices without registration. This permits the GA90 modular gateway to operate in back to back UAS mode.
The GA90 modular gateway has an IVR function that can prompt callers. This can be enabled or disabled separately for the IP, FXO, and T1/E1 ports.
When enabled, it provides authentication and two stage dialling. A call is answered by the GA90 modular gateway which then prompts the caller to enter a password, a number, or both, de¬pending on your criteria. When calls are received on the specific interface, the GA90 modular gateway will verify the password (if programmed), and collect the destination phone number. The call is then routed according to the routing table in the same way it would be if the IVR was not enabled on that port.
Most IP networks existing today support VLAN and using this feature can increase the voice quality of phone calls. The GA90 modular gateway fully supports IEEE 802.1Q VLAN tagging.
The system has an LCD on the front panel. This shows the status of the GA90 modular gateway and its IP address. This enables rapid deployment and troubleshooting.
The GA90 modular gateway provides Ping, Traceroute, and DNS Lookup for network diagnostic. These tools will help you identify most networking problems.
The GA90 modular gateway supports fax to devices connected to the analog FXS ports. This can be with fax pass through or with T.38 fax which is supported by most ITSPs.
The GA90 modular gateway has an HTML based administration UI so that it is not necessary to install any management software on a PC. The administration UI is intuitive and easy to navigate. You can access and manage the GA90 modular gateway from anywhere as long as you have a web browser and access to the Internet.
The administration UI provides various real time information and statistics of the GA90 modular gateway. These include operation state, system and network information, events and alarms, line status, and comprehensive call detail records (CDRs).
Zed-3 sells and supports its products worldwide. The GA90 modular gateway supports telephony protocols for many countries so it can connect directly to the local PSTN. You can navigate the GA90 modular gateway’s administration UI in English or Simplified Chinese.
