There’s a more economical way to connect multiple Tek-CARE®400 central equipment cabinets (CEs): Use the TC400 Network.
The TC400 Network uses NC554-series Ethernet switches to connect the PM451 Hub Control Module in the CE to the Tek-BRIDGE®, NC402TS masters, and NC465 Media Gateway. To connect multiple CEs together, just connect each of them to a single TC400 Network. See the diagram below for a visual representation of these connections. We’ve also updated the color system layouts:
This option makes the PM452 CE Communications Module unnecessary, so the PM452 has been discontinued.
