Zhone Feature-rich ADSL2+ 1U DSLAM enables IP video from the Remote Terminal/Street Cabinet in a native IP Ethernet DSLAM supporting multiple network connections

  Zhone - ADSL2+ 1U DSLAM w/ Modular Uplinks

Zhone's 4900 series of ADSL2+ 1U DSLAMs are ADSL ITU G.992.5 compliant IP DSLAMs, Ethernet based, environmentally hardened and small enough to fit in even the most crowded Remote Terminals/Street Cabinets. The 4929 uses EAPS for Ethernet ring topology support, for use with the IPD12000E DSLAM or other EAPS devices.

The 4929 is extremely feature rich, including IGMP snooping for IP Video support, SNMP Management, IP Traffic Management, enhanced security features, and up to 24 Mbps downstream bandwidth available on every port. Front loading, hot-swappable uplink module options called Media Interface Modules are available for installation into the DSLAM. MIMs include T1/E1, 100BaseFX, and 10/100 Ethernet for easy integration with other network elements as well as providing easy upgrades as bandwidth requirements increase. In addition MIM uplink options exist to add more Gigabit Ethernet Interfaces to the units

The 4929 interoperates with industry standard ADSL2+ modems over the local loop while still preserving the benefits of a packet based architecture.

Simultaneous voice and data support allows providers to take advantage of line sharing agreements and further reduces the cost of deploying the residential DSL services such as High-speed Internet Access, Multicast Video (IP TV), Video on Demand, Audio/Video streaming, Voice over IP, Gaming and LAN-to-LAN connections that will increase the providers Average Revenue Per User (ARPU).

ADSL2+ is an ideal voice and data solution for residential use, supporting data and POTS voice service over a single copper pair. By maintaining lifeline POTS, the voice connection is never terminated in the event of power loss.

ADSL2+ provides the high-speed bandwidth required to deliver IP video from the remote terminal.
