2.2.2 Optical Service Channel Cards

•PROT: Connected to the other MS-ISC-100T ports

The TCC is connected to the MS LAN by its front panel port. The back panel Ethernet port is disabled and cannot be used in the MS node.

2.2.2 Optical Service Channel Cards

The Optical Service Channel (OSC) is a bidirectional channel that connects all the nodes in a DWDM ring that transports general-purpose information without affecting client traffic. In its primary application, this channel carries data sub-channels for telemetry (supervisory) services for an optical system, provides orderwire applications, and provides transparent links between each node of the network for user-defined or proprietary functions.

The ONS 15454 has two OSC cards, the OSCM and the OSC-CSM.

Table 2-6shows the optical specifications for the OSCM card.
