ECM
Placement
The Ethernet Protection ECM allows NGE, NGE Plus, and EoPDH electrical port
cabling using Category 5 twisted-pair copper cable with Telco 50 connectors. The
ECM has two Telco 50 connectors on the front and two 2 mm type B connectors on the
back.
The Ethernet Protection ECM plugs into the main backplane two 2 mm connectors of
any valid odd or even slot. The 2-slot design provides direct cable access to one card
(n+1 of the pair) and occupies the width of two slots (n and n+1) on the backplane. Plug
the ECM into the 2 mm connectors of the right-most slot (n) as seen from the rear view
of the shelf.

Port Mapping Scheme
Port mapping schemes vary depending on the Ethernet card type:
•
4-port GbE (LX, SX, or CWDM) plus 16-port 10/100BaseTX
•
4-port GbE (LX or SX) plus 16-port 10/100BaseTX with CEP
•
4-port GbE (LX or SX) plus 16-port 10/100BaseTX with CEP and EoPDH
•
2-port GbE SX plus 2-port GbE CWDM (40 km) plus 16-port 10/100BaseTX
Ports 1 through 4 on these cards are optical ports. Ports 5 through 20 are 10/100
electrical interface ports. Connect the 16 electrical interface ports as follows:
–
Ports 5 through 8 connect to the first Telco 50 connector (ECM PORTS 9–12)
–
Ports 9 through 20 connect to the second Telco 50 connector (ECM PORTS
13–24)
•
2-port GbE TX plus 2-port GbE (LX or SX) plus 16-port 10/100BaseTX
•
2-port GbE TX plus 2-port GbE (LX or SX) plus 16-port 10/100BaseTX with CEP
•
2-port GbE TX plus 2-port GbE (LX or SX) plus 16-port 10/100BaseTX with CEP
and EoPDH
Ports 3 and 4 on these cards are optical ports. Ports 1and 2 are GbE TX electrical
interface ports. Ports 5 through 20 are 10/100 electrical interface ports. Connect
the 2 GbE TX and 16 10/100 electrical interface ports as follows:
–
Ports 1and 2 connect to the first Telco 50 connector (ECM PORTS 1–2)
–
Ports 5 through 8 connect to the first Telco 50 connector (ECM PORTS 9–12)
–
Ports 9 through 20 connect to the second Telco 50 connector (ECM PORTS
13–24)
