ADSL IP-DSLAM
Loop-H 3780/ U1000
ADSL IP-DSLAM
Description
The importance of IP has been validated by the year-to-year increase of new Internet applications. The adaptation of IP gives service providers much more flexibility and efficiency than the traditional ATM infrastructure. New advances in IP networking technologies have been introduced to change the landscape of broadband service offerings.
The H3780/ U1000 is an IP-based DSLAM that terminates all of the ATM circuits and convert the traffic directly into the Internet environment. IP-based DSLAMs provide a distinct advantage over typical ATM-based DSL access systems, due to the fact that IP is the most natural approach for data transmission, offers better bandwidth utilization, ease of use, and provides a low-cost advantages.
H3780/ U1000 supports both ADSL over single copper pair. Each enclosure accommodates two 8-port ADSL module The versatile service availability makes H3780/ U1000 ideal for both multi-tenant unit (MTU) and central office applications.
The ADSL module bridges the traffic between each ADSL port and built-in 100M Ethernet port back and forth as conventional Ethernet switch does. Namely, the ADSL module terminated all the ADSL ATM cell traffics and converts to IP packets. The ADSL module provides 8 ADSL ports to customers and one 10/100M Ethernet interface for uplink connection. One H3780/ U1000 can accommodate 2 ADSL modules to support up to 16 ADSL channels. To separate POTS and data traffic, the POTS splitter circuitry is built-in. This compact design totally eliminates the need of additional space.
The H3780/ U1000 also offers service providers extensive management capabilities. The entire H3780/ U1000 is managed by using an element management system (EMS). The information on configuration control, system status, performance index, alarm trap, etc. are forwarded from the H3780/ U1000 to EMS, which delivers service providers a comprehensive service results report. In addition to remote management capability, a console port is used for local management.
With the award-winning design, service providers are able to meet the diverse and ever increasing broadband demands of customers quickly and at lower costs than previously possible.
