The station timing is configured through the front panel (see Station Timing on
page 25) or through the terminal interface (see Station Timing on page 61). Pin
utilization is shown in the following table.
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).
