Tanımlama

Description:
IP DSLAM DAS-3224 and DAS-3248 provide a connection of the user equipment by technology ADSL. 24-Port IP DSLAM DAS-3224 and 48-port DAS-3248 are equipped with a built-in splitter POTS. Due to the design of compact DAS-3224 and DAS-3248 can be easily installed in a standard rack height 1U. IP DSLAM DAS-3224 and DAS-3248 supports bandwidth management, traffic prioritization and filtering. In addition, DAS-3224 and DAS-3248 support the mechanism of QoS, the services required to implement Triple Play. Both devices support standard ADSL / ADSL2 / ADSL2 +. DAS-3224 and DAS-3248 is the ideal solution for network providers offering residential and business customers services that require high bandwidth (for example, video streaming, online gaming and Internet telephony).
 
Broadband subscriber for infrastructure
24/48-Port IP DSLAM DAS-3224 and DAS-3248 is ideal for installation in apartment buildings, hotels, universities and multi-office commercial buildings. With support for next-generation telecommunications technology DAS-3224 and DAS-3248 enable service providers to deliver an efficient, easily configurable, and inexpensive access to the Internet. Providing more services in one transport network to optimize bandwidth and simplifies network access control.
 
Guaranteed bandwidth through the mechanism of QoS
To ensure quality of service (Quality of Service) DAS-3224 and DAS-3248 supports 4 priority queues IEEE 802.1p, and DSCP, which ensures minimal waiting for services that are sensitive to delays, such as voice or video, while traffic is not delay-sensitive services, including Web-traffic or file transfer to be transmitted depending on the available bandwidth.
 
The mechanism of Seamless Rate Adaptation (SRA)
Seamless Rate Adaptation (SRA) - a mechanism for dynamic configuration and settings installed ADSL connection (no additional re-synchronization with the DSLAM), defined in the specifications of ITU-T Rec. G.992.5. When using a SRA, speed and physical parameters of incoming and outgoing flows are automatically adjusted depending on the copper line.
