From the 8 VC-4s, two can be individually substructured to VC-12s to provide upto 2
x 63 VC-12s. In this case, the first 4 VC-12s are reserved for the E1 ports. Note that
in case E1 interfaces are used, the first VC-4 needs to be substructured, otherwise, they
are not available. In addition, 3 VC-4s can be individually substructured to VC-3,
thereby providing a total of 9 VC-3s.
The remaining 3 VC-4s cannot be substructured. For each of the 4 VCGs, a 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 following diagram illustrates the VC/VCG mapping for the EPL4_E14 option card.
Jumbo frame support
The EPL4_E14 option card supports overlength Ethernet frames (also known as Jumbo
frames) on LAN ports 7, 8, and 9, 10.
EPL4_E132_75 option card
Interfaces
On the faceplate the EPL4_E132_75 board provides:
•
Four RJ45 connectors for dual rate Ethernet (10/100Base-T)
•
Sixteen RJ45 connectors to cover 32 E1 interfaces with 75
Ω
only (2x E1 per
RJ45)
All four Ethernet RJ45 connectors have their own green and yellow LED which
indicates a LAN connection and traffic flow respectively.
The following figure shows the front panel of the EPL4_E132_75 option card.
