Concatenation of SHDSL links
It is possible to combine the capacity of multiple SHDSL links that run in parallel.
Thus the bandwidth of a link between LTU and NTU can be increased. Ethernet traffic
of up to 8 Mbit/s can be transported via a VC-12-4v. The individual SHDSL links
carry one TU-12 which contains one VC-12 member of the VC-12-4v group. The
Ethernet frames are encapsulated using GFP (Generic Framing Procedure) before
mapping into the VC-12-4v group. The LCAS protocol is used to dynamically control
the size of the VC-12-4v group.
