24-Port IP DSLAM 2 combo ports 10/100 / 1000Base-T / SFP
Thanks to a network uplink-interface Gigabit Ethernet (GE), IP DSLAM DAS-3224 / E / C provides a cost-effective solution for direct connection to IP-based networks through the Internet router or switch LAN.
IP DSLAM enables service providers to arrange for subscribers of broadband networks using existing copper telephone lines. Device supports ADSL / ADSL2 / ADSL2 + and advanced IP-services, including QoS, multicast, and subscriber management. These functions help to eliminate overloading the bandwidth and provide noise immunity and efficient transmission of video, voice and data network. Triple Play technology allows simultaneous transmission of content, bandwidth intensive: voice, video and data - in a single infrastructure. The device series DAS-3224 / E / C supports uplink-channel aggregation (association of uplink-channel GE into one logical interface). In addition, thanks to options Daisy Chaining, all connected devices can use the same uplink-channel GE.
DAS-3224 / E / C support limiting and filtering MAC addresses using a MAC-level service. The device also supports a one-way Loop Testing (SELT) for determining the state line to connect the modem. Bilateral Loop Testing (DELT) is mainly used to check the line after installing the modem. This function provides troubleshooting on lines with low productivity. Administration and Operations Management (OAM) is performed to ensure control, testing and monitoring. OAM loop-back is used to confirm the integrity of the virtual path or channel between different nodes on the ATM network.
Web-based management interface supports various functions, including monitoring the status in real time. IP DSLAM also allows monitoring and management through the Network Management System Network Management System.
To ensure quality of service (Quality of Service) DAS-3224 / E / C support 8 IEEE 802.1p priority queues, and network architecture DiffServ, which defines a simple mechanism for a structured classification and bandwidth management. DiffServ allows minimum waiting for services sensitive to delays - for example, voice or video, while traffic is not delay-sensitive services, including Web-traffic or file transfer to be transmitted according to the employment of bandwidth. DAS-3224 / E / C also supports packet classification based on MAC / IP-addresses and ports TCP / UDP.
DAS-3224 / E / C IP DSLAM 1,2U made in a metal housing and is designed for table top or rack mounting. The device can be mounted in a 19 "or 23" rack using the mounting kit.
IP DSLAM DAS-3224 / E / C 24 is equipped with ADSL-ports and 2 combo ports (10/100/1000 Base-T or mini-GBIC).
Using uplink-ports can be combined into a stack IP DSLAM device and aggregate multiple connections as a general network connection.
Due to the wide range of functions IP DSLAM, DAS-3224 / E / C are cost-effective and efficient solution for the implementation of broadband access systems of the next generation
