The following figure shows the front panel of the ESW4_E14 option card.
Transmission rates
The following transmission rates are supported with ESW4_E14:
•
Mapping Ethernet packets into VC12-Xv (X = 1...63)
•
Mapping Ethernet packets into VC3-Xv (X = 1...21)
•
Mapping Ethernet packets into VC4-Xv (X = 1...7)
Flexible bandwidth assignment
When the ESW4_E14 option card is inserted in tributary slot 1 of a 2m/4o or 1m/1o
version and the main unit is an M1-16/4, the total capacity of the unit is equivalent to
16 VC4s (2.5 Gbit/s) with which up to eight VCGs can be created and each VCG can
be assigned to a WAN port. For WAN ports 1 though 4, a capacity of eight VC4s (1
through 8) is available. By default, the 1st and 2nd VC4s are substructured in VC12s.
Similarly, the 3rd, 4th, and 5th VC4s are substructured as VC3s. Optionally, the 1st to
5th VC4s can be changed to unstructured VC4. The 6th, 7th, and 8th VC4s can only
be used as VC4s. As a result, VC12-Xv (X=1..63), VC3-Xv (X=1..9) and/or VC4-Xv
(X=1..7) groups can be created from at most 122 VC12s, 9 VC3s or 8 VC4s.
For WAN ports 5 through 8, a capacity of eight VC4s (9 though 16) is available. Of
these 8 VC4s, the 9th and 10th VC-4 are substructured in VC12s and the 11th, 12th,
and 13th VC4 are substructured in VC3s, by default. Optionally, the 9th to 13th VC4s
can be changed to unstructured VC4. The VC4s 14 through 16 can only be used as
VC4s. As a result, VC12-Xv (X=1..63), VC3-Xv (X=1..9) and/or VC4-Xv (X=1..7)
groups can be created from at most 126 VC12s, 9 VC3s or 8 VC4s.
