Important! The power of the 1643 AM / 1643 AMS must be switched off before
the option card is inserted.
X8PL option card
The X8PL option card provides eight Ethernet interfaces in Private Line mode for the
1643 AM / 1643 AMS. The Private Line mode enables traffic to be mapped from each
Ethernet port one-to-one into an SDH container. Thus a private connection from an
Ethernet port through an SDH network to another Ethernet port at the remote end of
the link is possible.
The X8PL option card supports a flexible allocation of SDH bandwidth to LAN ports
by making use of the Link Capacity Adjustment Scheme (LCAS, see
). All LAN ports have the same capabilities. Each WAN port supports VC-12-Xv (X =
1...63) or VC-3-Xv (X = 1...3).
The VC-12s that form one VCG can be chosen from any TUG-3, in any timeslot order.
However, it is recommended to select the VC-12s in sequential order, preferably in one
TUG-3. In this way the end-to-end network design can be kept simple and easy to
maintain.
The X8PL option card supports loopbacks on outgoing Ethernet and Fast Ethernet
signals.
