Table 5-2, “Allowable AS2000 shelf configurations,” on page 5-16 shows
several possible configurations of the AS2000 nodes.
Table 5-2 Allowable AS2000 shelf configurations
For a ConnecT1 Plus node, specify the arrangement of the shelves
accessed by this node. The only possible arrangements are such that the
number of
D s is equal to the number of shelves being used. (For
example, for the four-shelf maximum, the arrangement would be
D,D,D,D .)
The query path is used by Access Manager to query the node for status or
other information or to download to the node. The alarm path is used by
the node to report alarms to Access Manager.
Alarm Paths and Query Paths (and hence, their device types) are set from
the Node Definition screen
Before you can define these paths for the node, you must configure your
comlines to support the node’s access arrangement. The access
arrangement specifies the type of connection at each serial port of the
Access Manager PC.
Until now, if you wanted to set up an Alarm path or a Query path between
Access Manager and your system node, you were limited to using either a
direct connection, a modem, or a stat mux to connect.
If you’re using either Access System 2000 or ConnecT1 Plus equipment
with this new revision (Rev. 1.3) of Access Manager software, you also
have the option of using an X.25 PAD (Packet Assembler Disassembler).
This feature is not available with other Verilink ESF CSUs (for example,
the 551 series).
The options you have for connecting the Access Manager PC to the node
are summarized in Figure 5 -2, “How to connect the Access Manager PC
and the node,” on page 5 -17. An AS2000 node is shown because it’s the
only one which can use the X.25 PAD.
