14.9 Transponder and Muxponder Protection

Two types of protection are available:
•
•

14.9.1 Y-Cable Protection

Y-cable protection is available for the following ONS 15454 transponder and muxponder cards:
•
•
•
•
To create Y-cable protection, you create a Y-cable protection group for two TXP or MXP cards using
the CTC software, then connect the client ports of the two cards physically with a Y-cable. The single
client signal is sent into the Rx Y-cable and is split between the two TXP or MXP cards. The two Tx
signals from the client side of the TXP or MXP cards are combined in the TX Y-cable into a single client
signal. Only the active card signal passes through as the single TX client signal. The other card must
have its laser turned off to avoid signal degradation where the Y-cable joins.
Y-cable signal flow.
Loss of Signal–Payload (LOS-P) alarms, also called Incoming Payload Signal Absent alarms, can occur
Note
on a split signal if the ports are not in a Y-cable protection group.

Description
Green indicates that the port is carrying traffic (active) on the interface.
Amber indicates that the port is carrying protect traffic (MXPP_MR_2.5G).
