IDM-30AN Integrated Service Access Device

Overview:

The IDM-30AN Integrated Service Access Device adopts a modular structure design, integrating PCM and ADSL functions into one unit. It utilizes dedicated large-scale integrated circuits to complete signal processing for optical interfaces, E1 interfaces, and user interfaces.

Key Features:

◆ Flexible Optical Multiplexing Provides transparent transmission of up to 4 E1 channels, while offering 1-2 shared line-speed 100M Ethernet channels. The Ethernet interface features data frame filtering and MAC address auto-learning functions. The optical fiber rate is 155Mbps, with a transmission distance of no less than 40KM, optional SC/FC/ST interfaces, and support for single-fiber transmission mode.

◆ High Integration Provides 30 user interfaces in a 1U chassis, with over 20 optional service cards. The 4E1 cross-connection processing is currently the highest integration product available. Configuration can be selected based on traffic volume, enabling efficient resource utilization. The ADSL module has two slots, supporting multiple network modules, allowing users to conveniently upgrade from using one module to two modules simultaneously.

◆ Multi-functional Interfaces with Flexible Configuration Built-in 4 multi-timeslot card channels. Supports N×64K bandwidth V.35 cards and 10BASE-T cards. The multi-timeslot card channels can also be used to provide high-speed asynchronous RS232 or RS485 interfaces. The V.35 card can operate in both DTE and DCE modes, providing cost-effective V.35, 10Base-T and other multi-timeslot user interface cards. The PCM module adopts a board-card separation structure, supporting multiple integrated service sub-cards, allowing users to flexibly expand from the original number of integrated services to a maximum of 30 channels. The Ethernet multiplexer module supports hot-swapping, allowing two Ethernet multiplexer modules to be inserted into the ADSL slots simultaneously. Each access module connects to the G.SHDL Ethernet multiplexer module, aggregating traffic from 12 lines into one Ethernet port. Meanwhile, ADSL allows broadband data services and conventional voice services to coexist on the same telephone line. A built-in Ethernet module can connect the device to an Ethernet network, using Ethernet as the backbone to create a network providing G.SHDSL or ADSL services to hundreds of users.

◆ Rich User Interfaces with Flexible Access Methods The IDM-30AN/ADSL adopts an independent user module design, offering a variety of voice and data interfaces including 64K co-directional, V.24/V.28 (RS232/RS485), V.35 (N×64K), 10Base-T, polarity reversal and caller ID telephones (FXO, FXS), magneto, 2100Hz carrier magneto, hotline, carrier, EM 2/4-wire audio, high-fidelity audio, baseband trunk interface card, No.1 signaling card, telephone switching card, and over 30 other user interfaces. These can be freely changed according to user requirements. The large-capacity, high-integration design meets diverse user needs.

◆ Two-level Timeslot Cross-connection Function Built-in 128-timeslot cross-connection matrix. Enables user-to-user, user-to-line, and line-to-line data and signaling cross-connection. Therefore, this unit can also be used as a timeslot cross-connection device for 4 E1 lines.

◆ Multiple Clock Modes Supports master clock, external clock, line clock, and user clock modes. Can be configured as switch interface or user interface, compatible with both central office and remote end.

◆ Flexible Networking Capability Provides four directions of optical fiber line transmission/reception. Can be used in conjunction with the IDM-240 series, IDM-120 series, IDM-30 series, and IDM-mini series. Users can freely choose according to different capacity requirements and application scenarios, offering flexible, economical, and reliable networking.

◆ Network Management Function Features concise and comprehensive network management capabilities. Supports device configuration, query, fault statistics management, etc. The network management interface is available in both RS232 and RS485 formats. When using RS485, multiple devices can be cascaded simultaneously, and rack alarm output is also provided.

◆ Comprehensive Monitoring and Alarm Functions

The host unit can issue audible alarms when E1 status changes; panel indicators display specific alarm states; the device can output rack alarm information; the network management system can monitor device status at any time.

◆ Compact Structure with Easy Installation The device is 1U in height, mountable in a 19-inch rack, wall-mountable, or tabletop, significantly saving equipment room space. Available with 220V/-48V power supply, low power consumption at full configuration, adaptable to various installation environments.

◆ Dual Power Supply and Dual Ringing Current Backup Optional dual power supply and dual ringing current modules. The power supply operates in half-power mode, extending its service life. Additionally, if one module fails, normal operation continues.

Power supply and consumption: ~220V or -48V, power consumption less than 40W.

Typical Applications:

• Dedicated line access for integrated services such as voice, data, and video surveillance in electric power, public security, finance, education, and other systems
• Broadband/narrowband integrated service access for residential communities and intelligent buildings
• Data network extension for telecom, Netcom, and Unicom operators
