Китайско-телеком 48 портов ADSL2 + IP DSLAM

DSLAM5048is a 48ports IP-based DSLAM with splitter built-in. It terminates all the ATM circuits and converts traffic directly to deliver the most popular broadband IP services. DSLAM5048offers better bandwidth utilization, ease of use, as well as the low-cost advantage and provides the least initial investment solution for internet service providers who want to start providing broadband service in a low subscriber density location. DSLAM5048is compliant with ITU G.992.5, G.992.3, G.992.1, and backwards compatible with early version of ADSL. Its maximum downstream/upstream rate is up to 24/1.2Mbps and maximum reach distance is over 6Km. It is most suitable to provide high speed Internet access on existing copper twisted pair telephone lines. With the highly compact (1U height) and temperature-hardened design, simple installation and easy adaptation to local POTS/ISDN splitter requirements,DSLAM5048is an ideal solution for riple-play requirements deployed in indoor and outdoor nclosures. ADSL2+ Interfaces: 48 ADSL/ADSL2/ADSL2+ Ports with splitter built Supports ANSI T1.413 Issue 2, ITU G.992.5, G.992.3,G.992.1 (G.dmt), ITU-T G.992.2 (G.lite) Provides optimal rate/reach performance Rates up to 24.0 Mbps Distance up to 6.0 Km Multimode (automatic modulation detection) Supports packets transmit and receive statistics report Bandwidth Management control on each port at 32kbps interval Extended power management capabilities to optimize power consumption for each application Management SNMP-based GUI EMS Local RS-232 CLI Remote in-band SNMP/TELNET management Firmware upgradeable via FTP or TFTP Protocol Support IGMP snooping/ GMRP/ GVRP/ LACP SNMP/UDP/IP/MAC/Ethernet System Features: 2 10/100/1000 BASE-TX ports, one for uplink and another one for cascade Support up to 8 units to be cascaded SNMP Management Agent and MIB II TFTP BOOTP Client, Boot Server IP packet size 64 byte to 1522 byte PPPoE Intermediate Agent DHCP Relay Agent 8 VCs per ADSL port Support multiple PVC QoS configuration 128 MAC address per ADSL port 48*128 MAC address Bridging 1.
