Description:

 
Through a network interface uplink-Gigabit Ethernet (GE), IP DSLAM DAS-3248/E/C provides a cost effective solution for direct connection to IP-networks through the Internet router or switch LAN.

IP DSLAM allows providers to arrange for subscribers broadband access networks using existing copper telephone lines. The device supports ADSL/ADSL2/ADSL2 + and advanced IP-based services, including QoS, multicasting and subscriber management. These features help to eliminate bandwidth congestion and provide noise free and efficient transmission of video, voice and data network. Triple Play technology provides simultaneous transmission of content to the demanding bandwidth: voice, video and data - through a single infrastructure. The device supports the aggregation of a series DAS-3248/E/C uplink-channel (association uplink-channel GE into one logical interface). In addition, through option Daisy Chaining, all connected devices can use a single uplink-channel GE.

DAS-3248/E/C supports the restriction and filtering MAC address using MAC-level service. The device also supports one-sided test line (methods SELT) to determine the state line to connect the modem. Bilateral testing of the line (methods DELT) is mainly used for checking the line after installing the modem. This function provides troubleshooting on lines with low productivity. Administration and operations management (OAM) is to ensure control, testing and monitoring. OAM loop-back is used to confirm the integrity of the virtual route or channel between the various nodes in the ATM network.

Web-management interface supports several functions, including monitoring the status in real time. IP DSLAM also allows monitoring and administration from a network management Network Management System.

To ensure the quality of service (Quality of Service) DAS-3248/E/C supports 8 priority queues IEEE 802.1p and network architecture for DiffServ, which defines a simple mechanism for structured classification and bandwidth management. DiffServ allows for a minimum expectation for service, delay-sensitive - for example, voice or video, while the traffic is not delay-sensitive services, including Web-traffic or file transfers will be sent out depending on the employment of bandwidth. DAS-3248/E/C also supports packet classification based on MAC / IP-addresses and ports TCP / UDP.

DAS-3248/E/C IP DSLAM is carried out in 1,2 U metal case and is designed for desktop installation or rack mounting. The device can be installed in 19 "or 23" rack using a mounting kit.

IP DSLAM DAS-3248/E/C ADSL-equipped with 48 ports and 2 combo ports.

Using uplink-ports can be combined into a stack of the device IP DSLAM and aggregation of multiple connections to share a network connection.

With a wide range of functions IP DSLAM, DAS-3248/E/C are cost-effective and efficient solution for the implementation of broadband access next generation.
