1.2T line cards
This section describes the supported card modes, card configurations, and procedures to configure the card modes on the 1.2T line card.
A 1.2T line card-
supports both module and slice configurations,
-
provides flexible trunk and client port assignment.
The line cards are equipped with trunk and client ports:
-
Two trunk ports (0 and 1), and
-
12 client ports (2 through 13).
Configuration modes
You can configure the line cards in these two modes:
-
Muxponder mode: both trunk ports are configured with the same trunk rate. The client-to-trunk mapping is sequential.
-
Muxponder slice mode: the client-to-trunk mapping is fixed.
This table lists the client ports assigned to each trunk for the 1.2T card in muxponder slice mode.

Supported data rates on the 1.2T line card
The 1.2T line card supports these data rates.

![]() Note |
In all x50G configurations, client traffic on the middle port is affected with ODUK-BDI and LF alarms after the power cycle or link flap on the trunk side. This issue is raised when the two network lanes work in coupled mode and move from low to high power. To solve this issue, create a new frame either at the near-end or far-end by performing shut or no shut of the trunk ports. |
Coupled mode restrictions
These restrictions apply to the coupled mode configuration:
-
Both trunk ports must be configured with the same bits-per-symbol or baud rate. Both must be sent over the same fiber and direction.
-
The chromatic dispersion must be configured to the same value for both trunk ports.
-
When trunk internal loopback is configured, you must configure it on both trunk ports. If you configure internal loopback only on one trunk, traffic loss occurs.
-
Fault on a trunk port of a coupled pair may cause errors on all clients including those running only on the unaffected trunk port.
Configure split client port mapping
Use this task to configure the trunk port to client port mapping for sub 50G data ratesin the default mode or in the split client port mapping mode.

Regeneration mode
In an optical transmission system, 3R regeneration helps extend the reach of the optical communication links by reamplifying, reshaping, and retiming the data pulses.
Regeneration helps to correct any distortion of optical signals by converting it to an electrical signal, processing that electrical signal, and then retransmitting it again as an optical signal.
In Regeneration (Regen) mode, the OTN signal is received on a trunk port and the regenerated OTN signal is sent on the other trunk port of the 1.2T line card and the other way round. In this mode, only the trunk optics controller and coherentDSP controllers are created.
Regeneration can be configured only on the 1.2T line card.
Configure the card in Regen mode
Use this task to configure the regeneration mode on the 1.2T line card. The supported trunk rates are 100G to 600G in multiples of 100G.

|
|
Step 2 |
Commit and exit the configuration. Example:
|
Verify the Regen mode

Procedure
|
