IDM-30AN Integrated Service Access Device

Overview:

The IDM-30AN Integrated Service Access Device adopts a modular architecture design, integrating PCM and ADSL functions into a single 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 also offering 1-2 shared line-rate 100M Ethernet channels. The Ethernet interface features data frame filtering and automatic MAC address learning. The optical fiber rate is 155Mbps with a transmission distance of no less than 40KM. Optional SC/FC/ST interfaces are available, with support for single-fiber transmission mode.

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

◆ Multi-functional Flexible Interface 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-rate 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 architecture, supporting multiple integrated service sub-cards, allowing users to flexibly expand from their existing integrated service capacity up to 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, while ADSL allows broadband data services and conventional voice services to coexist on the same telephone line. A built-in Ethernet module is available; connecting the module to an Ethernet backbone network enables the creation of 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 cards, No.1 signaling cards, telephone switching cards, and 30+ other user interfaces. These can be flexibly reconfigured according to user requirements. The high-capacity, high-integration design satisfies diverse user needs.

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

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

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

◆ Network Management Functionality Features comprehensive and user-friendly 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 daisy-chained simultaneously, with rack alarm output capability.

◆ Comprehensive Monitoring and Alarm Functions

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

◆ Compact Structure, Easy Installation The device is 1U in height, mountable in a 19-inch rack, wall-mountable, or desktop-mountable, significantly saving equipment room space. Available with 220V/-48V power supply options. 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 service life. Additionally, if one module fails, the system continues to operate normally.

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

Typical Applications:

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