Voice over IP
AT-iMG1425 model offers two FXS ports, supporting analog POTS, FAX and dial-up modem services. It leverages 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.
CATV and IPTV
iMG1400 RF model supports 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.
Data delivery and security
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.
Optical WAN interfaces
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.
