IDM IAD02 IP Voice Access Gateway

The IDM IAD02 is an integrated access gateway that provides two analog telephone-to-IP network transmission access. It uses the standard SIP protocol and can interconnect with standard SIP softswitch systems, delivering VoIP/FoIP solutions for carriers, enterprises, and residential community users.

I. Device Configuration:

1. Provides 1 WAN port and 4 LAN ports. The WAN port supports both electrical (RJ45) and optical (FC) interfaces. In optical interface mode, it can interoperate with 100M Media Converters;
2. Provides 2 analog telephone interfaces (FXS) and 1 lifeline interface (FXO). The first telephone can dial "0" to connect to the PSTN (or connect to PSTN via the configured method in network management). During a power outage, the first telephone automatically connects to the PSTN network.

II. Functional Description:

1. Supports the standard SIP protocol, supports dual-server registration settings, and supports dual-backup for the call control center, enabling rapid switching during network failures to ensure uninterrupted service;
2. Supports VLAN partitioning, supports 802.1q and 802.1p protocols, and allows setting QoS priority and VLAN tags for voice data streams, significantly enhancing service protection capabilities;
3. System supports VPN (PPTP & L2TP);
4. The system registers to the server via the WAN port and allows configuration login to the terminal through both WAN and LAN ports;
5. Supports T.38 real-time fax;
6. Supports multiple ITU-T codec standards such as G.711, G.729A, G.723.1, and supports dynamic jitter buffer management, echo cancellation (meeting ITU-T G.168/165 standards), packet loss compensation technology, Voice Activity Detection (VAD), and Comfort Noise Generation (CNG). It can be placed directly behind an ADSL Modem, automatically running the PPPoE protocol to activate the enterprise internet interface, with automatic redial upon PPPoE disconnection;
7. Supports DHCP and DNS client protocols, and supports automatic IP address acquisition;
8. Even if the uplink internet interface is interrupted, the IDM IAD02 device can still make internal calls and can make/receive calls through the traditional PSTN network, ensuring normal telephone service;
9. Supports WEB-based network management.

V. Application Examples:

Figure 1 Access to SIP Protocol IP Network (Electrical Interface Type)

This device can also register directly to a SIP server via the IP network to expand the IP phone capabilities of an existing system. Additionally, the device supports analog trunk interfaces for connection to traditional PSTN networks, adapting to complex network environments.

Figure 2 Used with Optical Ethernet Switch (6U) (Optical Interface Type)

Using our company's high-capacity optical Ethernet switching device, the IDM MSAP-G3CP, as the core switching center, which provides SIP registration services and softswitch functions, it directly connects to multiple remote IAD02 devices via optical Ethernet interfaces, enabling IP phone and Ethernet data service access applications.

Figure 3 Used with Optical Ethernet Switch (1U) (Optical Interface Type)

Using our company's compact optical Ethernet switching device, the IDM 2GE8FE, as the core switching center, which provides SIP registration services and softswitch functions, it directly connects to multiple remote IAD02 devices via optical Ethernet interfaces, enabling IP phone and Ethernet data service access applications.

Figure 4 Used with Media Converters

In locations with relatively long transmission distances, this device can be cascaded directly via optical ports with media converters and other equipment to meet IP phone access applications in edge networks.
