GATEWAY GXW450X OVERVIEW The GXW450X series are E1/T1/J1 Digital VoIP Gateways that allow digital PSTN and ISDN trunks to be integrated with VoIP networks. By connecting the GXW450X series with a VoIP network and traditional PBX or E1/T1/J1 providers, businesses can drastically increase the number of PSTN/ISDN trunks integrated with their VoIP network and the concurrent calls supported. The GXW450X series offer three models that provide 1, 2 or 4 T1/E1/J1 spans and support 30, 60 or 120 concurrent calls.

The following figure shows a configuration example: • If a host at IP address 192.168.2.5 initiates more than 100 TCP connections to the GXW450X, it will be added into GXW450X blacklist. This host 192.168.2.5 will be blocked by the GXW450X for 500 seconds. • Since IP range 192.168.2.10-192.168.2.20 is in whitelist, if a host initiates more than 20 TCP connections to the GXW450X within 1 minute, it will not be added into GXW450X blacklist. It can still establish TCP connection with the GXW450X.
