NTP-G33 Create a Y-Cable Protection Group
NTP-G33 Create a Y-Cable Protection Group
Note Loss of Pointer Path (LOP-P) alarms can occur on a split signal if the ports are not in a Y-cable protection
group.
Step 1 View the Cisco MetroPlanner Traffic Matrix (see Table 3-1 on page 3-3) for your site. Verify the TXP
or MXP cards that need Y-cable protection groups. (Cards requiring Y-cable protection are indicated
with “Y-Cable” in the Traffic Matrix table Protection Type column. Refer to the Cisco MetroPlanner
DWDM Operations Guide for more information.)
Step 2 Verify that the TXP or MXP cards are installed according to the requirements specified in Table 5-2. This
table describes the protection types available in the ONS 15454 for DWDM client cards.
Step 3 Verify that PPMs are provisioned for the same payload and payload rate on the TXP and MXP cards
where you will create the Y-cable protection group.
Purpose This procedure creates a Y-cable protection group between the client ports
of two transponder (TXP_MR_10G, TXP_MR_10E, or TXP_MR_2.5G)
or two muxponder (MXP_2.5G_10G, MXP_2.5G_10E, MXP_MR_2.5G,
MXPP_MR_2.5G) cards. For additional information about Y-cable
protection, see the “16.9.1 Y-Cable Protection” section on page 16-114.

Pairs a working transponder or muxponder card/port with a
protect transponder or muxponder card/port. The protect port
must be on a different card than the working port and it must be
the same card type as the working port. The working and protect
port numbers must be the same, that is, Port 1 can only protect
Port 1, Port 2 can only protect Port 2, etc.
Splitter TXPP_MR_2.5G
MXPP_MR_2.5G
A splitter protection group is automatically created when a
TXPP_MR_2.5G or MXPP_MR_2.5G card is installed. You can
edit the splitter protection group name.
