Important! Please note that an in-service upgrade of the SHDSL option card from
an older release to Release 6.1 and later versions is not possible. It is always
necessary to unassign the X12SHDSL card completely, so that all connections are
removed. Then the upgrade can be done and the X12SHDSL card can be assigned
and configured from scratch.
E1 and TU12 payload mapping
The 1643 Access Multiplexer AM / 1643 Access Multiplexer Small AMS LTU supports
two types of payload mapping into the SHDSL signal:
• E1 mode, maps an E1 directly into the SHDSL signal
• TU-12 mode, maps a TU-12 containing a VC-12 into the SHDSL signal. The
VC-12 may contain various signal types, e.g. E1, Ethernet data, etc.
