2-10 I NSTALLATION
NMS
Connection The PRISM 3001 is fully compatible with the TxPORT EM8000 Element Manager
and 8100A Site Controller. The EM8000 and 8100A software systems are used to
manage small to large networks of TxPORT network access products.
An element may be accessed by using an RS-232 connection from the serial port
of the computer running the EM8000 program to the element’s SUPV port or the
NMS IN and NMS OUT ports. The different connection methods are described in
the following paragraphs.
SUPV The EM8000 workstation or the 8100A Site Controller may be directly connected
to the 6-pin modular serial port connector labeled SUPV (also refer to Supervisory
Port Connection on page 2-9). When a group of elements is connected in an NMS
chain, the EM8000 or 8100A may be connected to the supervisory port of any one
of the elements. This element can then route messages onto the NMS chain to
reach the other elements. The call on alarm (COA) feature works through the
SUPV port only.
NMS
IN/ OUT
The two 6-pin modular connectors labeled NMS IN and NMS OUT on the rear
panel may be used for connection to the EM8000 or 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 2-7. 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.
