New Product: Corecess 6800 Intelligent Access Server
Product Overview (SPC configuration)
The Corecess 6800 is an IP-based Intelligent Digital
Subscriber Line Access Multiplexer (iDSLAM) that can be
used by service provider companies offer broadband multi-
services on copper-based local loop last mile access network.
Corecess 6800 is built to provide intelligent IP services as the
networks evolve. It delivers various DSL interfaces and
advanced IP services including. With these service features,
companies can greatly increase their revenues and maximize
Corecess 6800 intelligently and economically combines three
devices in one. As compared to the legacy DSL systems, the
Corecess 6800 system combines the functionalities of ATM
switch, DSLAM, NAS, and Router into one compact system. This design makes the Corecess 6800 the most
economical and the most suitable solution for the next generation broadband access platforms. It provides among
other advantages; easy maintenance and easy installation, which in turn reduce operating cost and network down
Key Features and Benefits
Multiservice Platform for MDU and MTU
Corecess 6800 supports high port density with effective network management.
Corecess 6800 is designed for Internet services such as interactive gaming at home and video
conferencing at office.
Corecess 6800 offers ADSL, SHDSL and VDSL to support wide range of services.
SHDSL interface provides a leased line service for MTU with low cost.
Corecess 6800 can route local traffics and then, relieves the burden to backbone network.

ACLs on all VLANs to prevent unauthorized data flows to be bridged within VLANs.
Private VLAN edge provides security and isolation between ports on a switch, ensuring that voice traffic
travels directly from its entry point to the aggregation device through a virtual path and cannot be
directed to a different port.
MAC-based port-level security prevents unauthorized stations from accessing the switch.
DHCP filtering also prevents unauthorized stations from accessing the switch.
Multilevel security on console access prevents unauthorized users from altering the switch configuration.
IP Service Creation Platform
IP service creation through Dynamic Host Configuration Protocol (DHCP) server.
Several kinds of Access Control Lists (ACLs) makes reliable network.
Static IP routing for manually building a routing table of network path information.
Inter-VLAN IP routing for full Layer 3 routing between two or more VLANs.
Equal cost routing for load balancing and redundancy.
Highly scalable in port density and speed. (See Ordering Guide)
Built-in Web-based Management Software provides an easy-to-use Web-based management interface
through a standard web browser. (Web Console)
Simple Network Management Protocol (SNMP) v1 and v2c, and Telnet interface support delivers
comprehensive in-band management, and a command-line interface (CLI)-based management console
provides detailed out-of-band management.
CLI provides easy-of-use user interface and command set
Through ViewlinXTM network management software user can manage Corecess 6800 in detail like as in-
band and out-band management.
Through Corecess 1500TM (A Corecess Operation Support System (OSS)), Corecess 6800 is manageable
end-to-end QoS policies (planned future software support). (Service Level Agreement (SLA)
VLAN trunks can be created from any port using either standards-based 802.1Q tagging or VLAN
IGMP snooping provides for fast client joins and leaves of multicast streams and limits bandwidth-
intensive video traffic to only the requestors.

Embedded Remote Monitoring (RMON) software agent supports four RMON groups (History, Statistics,
Alarms and Events) for enhanced traffic management, monitoring, and analysis.
Domain Name Services (DNS) provide IP address resolution with user-defined device names.
Trivial File Transfer Protocol (TFTP) reduces the cost of administering software upgrades by
downloading from a centralized location.
Network Timing Protocol (NTP) provides an accurate and consistent timestamp to all switches within
Multifunction LEDs per port for port status, half-duplex/full-duplex, 10BaseT/100BaseTX indication, as
well as switch-level status LEDs for system, redundant power supply provides a comprehensive and
convenient visual management system.
Auto-negotiating on all ports automatically selects half- or full-duplex transmission mode to optimize
Dynamic Host Configuration Protocol (DHCP) relay allows a broadcast DHCP request to be forwarded
to the network DHCP server.
The default configuration stored in Flash ensures that the switch can be quickly connected to the
network and can pass traffic with minimal user intervention.
