Page 8 User’s guide ref 9014709-01 XSLAN Shdsl switch

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).
