Common use of Loopback (Optional) Clause in Contracts

Loopback (Optional). 5 The CFP module may support loopback functionality. Loopback commands are accessed via the MDIO 6 management interface. Suggested loopback orientation implementation is TX0 to RX0. The host loopback 7 and the network loopback are oriented per Figure 4-2 shown below. Host loopback loops the „M‟ host lanes. 8 Network loopback loops the „N‟ network lanes. The capability to support the loopback functionality is 10 block is application dependent. If PRBS checkers and generators are supported, they will be located in the 11 “Gearbox/CDR” block. The CFP MSA module vendor will specify which loopback functionality, if any, is 12 available. For details on controlling the loopback mode, please refer to “CFP MSA Management Interface 13 Specification”. 15 Figure 4-2: Optional Loopback Orientation
