selection can be made between VC-12-Xv (X=1-63), VC-3-Xv (X=1-9), and VC-4-Xv
(X=1-7), based on the total number of containers that are available for each type.
The VC/VCG mapping is shown in the following figure:
Jumbo Frame support
The EPL4_E132_75 option card supports overlength Ethernet frames (also known as
Jumbo frames) on LAN ports 35 and 36.
ESW4_E14 option card
Interfaces
On the faceplate, the ESW4_E14 card provides:
•
Two LAN ports for Small Form-factor Pluggable (SFP) optical transceivers which
support 1000Base-X optical SFPs or can be used as 10/100/1000BASE-T electrical
ports using RJ-45 connectors.
•
Two LAN ports for dual rate Ethernet (10/100Base-T) using RJ-45 connectors.
•
Two RJ-45 connectors on the faceplate for four E1 interfaces with 75/120
Ω
(Selection can be made on port level via the user interface; default is 120
Ω
).
The ESW4_E14 option card provides 4 Ethernet ports. Two of these (5 and 6) support
10/100 Base-T line rates, while the other two (pairs 7/8 and 9/10) are multirate and
capable of 10/100/1000 Base-T/-X rates. For these ports, the selection between 1000
Base-T (electrical interfaces 8 and 9) and 1000 Base-X (optical interfaces 7 and 10)
must be done via the ITM-CIT. This selection can be done independently for each Port.
When an optical port is in use, the electrical counterpart is inactive and vice versa.
Each connector and each SFP has its own green LED (data link up: LED ON or down:
LED OFF) and yellow LED (transmission: LED ON or no transmission: LED OFF).
The total transmission backplane capacity is 16 x VC-4s. This capacity is only
available in combination with an MI-16/4 main card, provided the ESW4_E14 card is
placed in the first slot (TS1). In any other slot or when combined with the MI-14/4
main card, the maximum useable capacity is 10 x VC-4s.
