Card Reference

Figure 16-54

Two TXP_MR_10G cards can be joined in a Y-cable protection group. In Y-cable protection, the client

ports of the two cards are joined by Y-cables. A single incoming receive (Rx) client signal is injected

into the Rx Y-cable port and is split between the two TXP_MR_10G cards (connected to the Rx client

ports) in the protection group. The transmit (Tx) client signals from the two protection group

TXP_MR_10G cards are connected to the correspondent ports of the Tx Y-cable. Only the Tx client port

of the active TXP_MR_10G card is turned on and transmits the signal toward the receiving client

equipment. See the

information.

If you create a GCC on either card of the protection group, the trunk (span) port stays permanently active,

regardless of the switch state. When you provision a GCC, you are provisioning unprotected overhead

bytes. The GCC is not protected by the protect group.

16.8.1.2 Automatic Laser Shutdown

The ALS procedure is supported on both client and trunk interfaces. On the client interface, ALS is

compliant with ITU-T G.664 (6/99). On the data application and trunk interface, the switch on and off

pulse duration is greater than 60 seconds. The on and off pulse duration is user-configurable. For ALS

provisioning information, see the
