Avaya G250 Media Gateway OverviewThe G250 supports the connection of PCs, LAN switches, IP telephones, analog telephones, and trunks, via fixed analog and PoE ports on the chassis. A media module slot supports either of two WAN media modules, for connection to a WAN. There are several models of the G250, with various port combinations for support of analog, BRI, or T1/E1 trunks or DCP telephones, as described below.The G250 is available in the following models:Analog model (G250-Analog). The G250-Analog includes four analog trunk ports, two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.BRI model (G250-BRI). The G250-BRI includes two ISDN BRI trunk ports, one analog trunk port, two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.DCP model (G250-DCP). The G250-DCP provides twelve DCP (Digital Communications Protocol) ports, as well as four analog trunk ports, two analog line ports, a Fast Ethernet WAN port, and two LAN ports.DS1 model (G250-DS1). The G250-DS1 provides a T1/E1 and a PRI trunk port, enabling support of fractional T1/E1 and PRI. The G250-DS1 also includes one analog trunk port, two analog line ports, a Fast Ethernet WAN port, and eight PoE LAN ports.G250 Physical DescriptionsV1 — ICC/LSP SlotV2 — WAN Media Module SlotAnalog port LEDsAnalog trunksAnalog line portsSystem LEDsConsole portUSB portContact Closure (CCA) portEthernet WAN (ETH WAN) portETH LAN portsDCP portsDCP port LEDsFeaturesG250 and G350 features include:VoiceSupport for traditional telephones and trunks.
