Traffic provisioning
X8PL option card
The X8PL option card provides eight Ethernet interfaces in Private Line mode for the
1643 AM and 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
Adjustment Scheme (LCAS)" (p.
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 time slot
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.
Physical interfaces
The physical interface function provides the connection to the Ethernet network of the
end-customer. It performs autonegotiation, and carries out flow control.
The following physical interfaces are enabled on Alcatel-Lucent TransLAN
• 10BASE-T
• 100BASE-TX
• 1000BASE-SX
• 1000BASE-LX
The supported LAN interfaces for Ethernet and Fast Ethernet applications are
10BASE-T and 100BASE-TX. The numbers "10" and "100" indicate the bitrate of the
LAN, 10 Mbit/s ( Ethernet) and 100 Mbit/s (Fast Ethernet) respectively. The "T" or
"TX" indicates the wiring and the connector type: Twisted pair wiring with RJ-45
connectors.
The supported LAN interfaces for Gigabit Ethernet applications are 1000BASE-SX,
1000BASE-LX, and 1000BASE-ZX. Again, the number indicates the bitrate of the
LAN, 1 Gbit/s (Gigabit Ethernet). "SX" indicates a short-haul interface, "LX" and
"ZX" indicate a long-haul interface.
Ethernet switch
The Ethernet switch connects the LAN ports with the WAN ports. It performs learning,
filtering, and forwarding according to the IEEE 802.1D standard.
The physical Ethernet switch can be logically split in multiple, independent switches or
port groups, called "virtual switch". In the transparent tagging modes (LAN
interconnect or LAN-VPN), also the name "LAN group" is used instead of "virtual
switch".
