AccessGain DSLAM is a Digital-Subscriber-Line-Access-Multiplexer targeted to meet both typical carrier applications and access network needs.

Main Features

Faster and Easier Internet Access and Interconnection with ATM DSLAM infrastructure

Today’s bandwidth-hungry application such as Internet access, remote LAN Access, teleconferencing, workgroup and data sharing, telecommuting and numerous varieties of digital video services are driving today’s demand for high-speed data network Access.

S-Access GmbH designs, develops and markets transmission systems based on Digital Subscriber Line (DSL) technology for copper wire plant. They support all contemporary data rates, from 64 kbps to multi-megabit symmetric and asymmetric transmission for voice, video and data communications over a single copper pair. S-Access GmbH Access systems link enterprise LANs and Network Service Providers over private and public networks across the local loop, the connection between the customer and the first network node.

Using the latest DSL technology, S-ACCESS GMBH AccessGain series offers service providers a very cost-effective solution for immediate implementation of multiple services in private and public networks.

SA-ACE16 is one product of the AccessGain series, it acts as a standalone IP-based DSLAM, which can concentrate and manage up to 16 DSL lines. User can use local RS232 CID and/or remote TELNET/SNMP to manage the SA-ACE16 directly.

Since the ATM backbone coverage is not so general in the real broadband network environment. Instead of traditional DSLAM system provides ATM uplink interface, the SA-ACE16 concentrates 16 ports of the ATM over DSL traffic which is encapsulated by DSL CPEs, and maps each user’s data encapsulated in ATM-PVC to Ethernet-with/without VLAN-tag packet (depends on the VLAN was enabled or not for the specified ATM ports), and then uplink to Telco or ISP directly, User can enable VLAN-PVC mapping capability for each DSL port independently. The SA-ACE16 acts as bridge for the DSL ports without enabling the VLAN-PVC mapping feature. In addition, it also acts as a manageable SNMP- based layer2 concentrator.

SA-ACE16 provides both Ethernet-VLAN and non-VLAN to ATM-PVC mapping feature and bridge mode for the ISP to isolate user’s data with security and to provide lots of service enhancement capabilities. SA-ACE16 supports 2 ATM PVC links for each DSL CPE.
