The FireRack Dual-Mini is a firewall/router designed for bonding two ADSL/ADSL2+ lines.
Hardware Specification
- AMD Geode LX800 500MHz processor
- 512MB DDR400 RAM
- 2 x ADSL2+ Ports
- 2 x 10/100 Ethernet Ports
- 2 x USB ports (one external)
- Mini PCI socket
- Compact Flash socket
- RS-232 Serial
Although most of our customers use the FireRack Dual-Mini on the Netservers ADSL network, the device itself is compatible with any ADSL service that supports the industry standard Multilink-PPP protocol (MLPPP). This is the very same protocol used by Cisco and other standards compliant routers.
Annex-A and Annex-M support
Up until relatively recently, all ADSL in the UK was "Annex-A". This provides up to 24Mbps download and up to 1.3Mbps upload rates. The difference with Annex-M is that the upload rates can go as high as 2.5Mbps. This is done by trading some of your download bandwidth for additional upload bandwidth.
Comparing Annex-A to Annex-M
Max. Download Rate (per line) | Max. Upload Rate (per line) | |
Annex-A | 24Mbps | 1.3Mbps |
Annex-M | 16Mbps | 2.5Mbps |
