XMP1 Release 5.5 System Description
SDSL extension in XMP1
Aastra Proprietary Information Page 5-3
In XMP1 subracks already available, the SDSL extension can be used in
two different modes:
• Integrated SDSL
• Stand-alone SDSL
Integrated SDSL
In the "integrated SDSL" mode, the SHDSL extension represents an
alternative to an external SHDSL solution and/or can be used as substitute
for HDB3 port modules. The ISHDSL module provides four internal 2 Mbit/s
interfaces to the XMP1 system. 2 Mbit/s signals from the switching matrix of
the XMP1 system can be routed via these interfaces and can be applied to
the SHDSL interface.
Stand-alone SDSL
In this operating mode, a XMP1 subrack can be used as low-cost SDSL
transmission system without multiplexing and cross-connect functions. Only
the external 2 Mbit/s interfaces are used. Cross-connections via the
switching matrix are not possible. In this application, the XMP1 subrack will
be equipped only with the central modules such as the Central Unit and
power supply module as well as with the SHDSL and FSP modules required
for the SDSL application.
The configuration is performed by means of the SOX LCT.
