Ethernet WAN port capacity configuration rules
The encapsulated Ethernet frames are mapped in VC-12 (2 Mbit/s), VC-12-2v (4
Mbit/s), VC-12-3v (6 Mbit/s), VC-12-4v (8 Mbit/s), VC-12-5v (10 Mbit/s), VC-3 (50
Mbit/s) or VC-3-2v (100 Mbit/s). A user can provision the actual bandwidth per WAN
port. Since the cross-connect capacity of a Metropolis
®
AMU is limited, the total
combined bandwidth of all WAN ports together must follow the WAN capacity
configuration rules defined in the table below.

The throughput mentioned in the table above are the maximum settings, it is also
possible to have less throughput for a certain WAN port (for example 6 Mbit/s
(VC-12-3v)).
Notice that only the WAN port bandwidth dictates the effective end-to-end Ethernet
communication throughput, not the LAN ports. The Metropolis
®
AMU equipped with
the TransLAN
®
option board keep track of the available capacity according to the rules
defined in the WAN port configuration table above. If an attempt to configure a new
WAN port capacity violates the rules, not only the system will not grant the new
configuration but also an alarm (message) will be triggered and displayed.
Ethernet WAN port mapping
The WAN port mapping of the X4IP-V2 is shown in the following table. In case the
units in service do not use the same termination points, adaptation via the LO cross
connect is required.
