JL-2000MD
MED-DENSITY 9U 16 LINE CARD SLOTS CHASSIS

DESCRIPTION

JL-2000MD system is the MDU (Multiple Dwelling Unit) Routing Concentrator most suitable for Internet Service Providers with MDU network such as Hotel, Motel, multi-tenant apartment, multi-tenant commercial, multi-tenant student dorm, campus, and local loop. The access routing concentrator can accommodates up to 12 line cards. With the high bandwidth flexible backplane design, the system combines variety technologies to meet with different kinds of market requirements such as ADSL2+ Line Cards. The ADSL2+ Line Card supports the asymmetry data up to 24/1Mbps with rate control capability and distance up to18K ft.
The JL-2000 MDU Routing Concentrator also provides the gigabit Ethernet routing switch control card with network management for the end-to-end operation, network administration, maintenance, and provisioning of the MDU access concentration. Tc The phone line card can be operated either stand-alone or with the gigabit Ethernet routing switch control card. The wide AC voltage operating range supports worldwide operation.
The system provides flexible and variety bandwidth services depend on the subscriber demand. This solution brings faster 24.0Mbps ADSL2+ with long distance networking Internet services to the subscribers by using existing phone-line found in the home and business. Thus, the phone line cards share the existing POTS (Plain Old Telephone Service) wiring to provide connectivity to subscribers, eliminating the need for new wiring. With ADSL2+, the voice and data operates simultaneously over the same pair of copper wire without interfering with voice service. The Concentrator can be remotely managed and software upgraded. This function eliminates the need for field upgrade. All cards are hot swappable which minimize service outage times.
Product Features:
