The iMG1400 Series intelligent Multiservice Gateways, part of the Allied Telesis iMG family, provide IPTV and broadband services with optional voice and fiber to RF transceivers. Allied Telesis iMG1400 Series intelligent Multiservice Gateways are flexible customer premise offerings that deliver IP-based services including carrierclass telephony, high-speed Internet, IP television, and interactive two-way videobased services over a Gigabit active optical distribution network. Advanced services such as Gigabit Internet, VoIP, IPTV and Video on Demand can be quickly delivered in a scalable way with complete remote management. A single device interconnects all peripherals, computers, analog and VoIP telephones to a single broadband uplink. In addition, service providers can offer CATV over a separate fiber with iMG1400 RF models. AT-iMG1425 models offer two FXS ports, supporting analog POTS, FAX and dial-up modem services. They leverage the existing Allied Telesis SIP and/or MGCP protocols and established interoperability with major softswitch vendors to support analog-based voice, FAX and modem services for residential and SoHo environments. VoIP Quality of Service (QoS) is maintained through Type of Service (ToS) bits and IEEE 802.1p priority tagging. In addition, silence suppression and local generation of comfort noise results in excellent voice quality. iMG1400 RF models support both CATV RF video delivery and IP TV video simultaneously over two separate fibers. The fiber to RF video receiver can be activated and deactivated through remote CLI commands or via the AlliedView NMS, allowing graceful migration from CATV RF video to IP video without a truck roll. The iMG1400 Series supports IP TV multicasting along with IGMP snooping, proxy, and fast leaves and join, enabling multiple high-quality, high bit-rate video streams without impacting data traffic or IP telephony. Combined, this delivers the fast channel change that users expect from video services. The iMG1400 Series supports IEEE 802.11bgn wireless transmission frequencies, supporting wireless transmission within the premise and support services without additional wiring. The iMG1400 Series supports industry leading QoS through ISO Layer 2 and 3 prioritization techniques including priority tagging with IEEE 802.1p, ToS and DSCP fields. Extensive support for per-port rate-limiting in the iMG1400 Series enables service providers to deliver tiered data services for any end customer profile, and provides maximum flexibility in service differentiation. Further, the hardware fully supports Q-in-Q. Security is assured by an integral Stateful Inspection Firewall with NAT to protect end-user networks. The iMG1400 Series is designed to be easy to deploy and manage. With the AlliedView NMS software platform, these iMGs can be remotely provisioned and managed. The iMG1400 Series supports TR-069 and can be managed via an Auto Configuration Server (ACS). The iMG1400 Series can accept up to two single-strand optical fiber links for FTTH applications - one for CATV RF video and the other to provide IP-based voice, video and data. The iMG may be operated without a fiber interface and perform as an Ethernet-only gateway.
