SHDSL option card
The SHDSL feature is used to transport 2 Mbit/s signals over copper lines in cases
where no fiber is available for transportation.
This option card can be used for the following applications:
• to connect UMTS base stations to the SDH network when only copper lines are
available
• to deliver ISDN PRI to customers over copper lines.
In the first application an n* 2 M bit/s connection to a UMTS base station is provided
over copper pairs (max. 3.5 km). In the base station, the termination of the SHDSL
signal (the NTU function) can be done by off-the-shelf modems. It is expected that
each UMTS service provider is expected will need four 2 M bit/s links; a base station
will be used by at most three providers. Another application consists of the delivery of
an ISDN 2 Mbit service over SHDSL.
The following figure shows an application with UMTS base station and NTU modems
The WaveStar® ITM-SC supports this option board on the 1643 AM or 1643 AMS.
The SHDSL option board can be added to the 1643 AM or 1643 AMS to provide
capabilities in addition to those that are provided by the main board: the option board
provides 12 Symmetrical single-pair high-bitrate Digital-Subscriber Line (SHDSL)
interfaces.
The SHDSL option card supports outloop loopbacks on all ports.
