2 Product overview
2.1 Function
The XSLAN shdsl switch enables to extend an Ethernet network over
kilometres using one or two simple voice-grade twisted pairs
(telephone lines).
Point to point
1 pair (up to 2.3 Mb/s)
2 pairs (up to 4.6 Mb/s)
2.2 Shdsl operations
The XSLAN comes with 1 or 2 SHDSL interfaces which allow to extend
an ethernet network at up to 2.3 Mb/s with 1 pair or 4.6 Mb/s with 2 pairs.
2.2.1 Data rate
Each SHDSL interface features an adaptive data rate from 128 Kb/s up to
2.3 Mb/s.
The data rate is a function of the cable quality and the distance with the
next SHDSL switch. For instance, the maximum distance between 2
switches through a line is 13 Km (8 miles) with a 0.9 mm wire diameter
cable.
2.2.2 Distance between switches
The table in appendix 1 gives the data rate which can be expected over a
line versus the length of the line (distance between 2 switches).
