TM-3000/II chassis is a high-capacity enclosure with up to 17 fullsized and up to 10 half-sized slots. The TM-3000/II can be configured

to a wide variety of network element (NE) types or combination of NE types.

The generic backplane imposes no restrictions on NE type or NE combinations. As an example, multiple fiber links can be connected to

a TM-3000/II node where the plug-in units are configured into terminal multiplexer, add-drop multiplexer (ADM) or ROADM functions. This flexible approach is unique and eliminates the challenges associated with static NE type, such as terminal multiplexer only or add-drop multiplexer only NEs.
