Network

Management

The unit is fully compatible with the Verilink Site Manager, the 8100A. The

8100A software system can be used to manage small to large networks of network

access products.

NMS Connection The two 6-pin modular connectors labeled NMS IN and NMS OUT on the rear

panel may be used for connection to the 8100A. This port is configured in this

manner to allow the connection of multiple collocated units in a daisy chain

IN/OUT bus arrangement as shown in Figure 2-4. The OUT port of one element is

connected to the IN port of the next element, and so on, to form a complete chain

among the group of elements.

All units on the same NMS chain must use the same NMS bit rate.

The NMS IN connector provides both the transmit and receive signal pair. This

port may be used for a modem connection or as a VT100 terminal interface (refer

to chapter Terminal Operation on page 45).
