Specifics are given in Table 5-4, “Selecting baud rates by equipment type

and access type”.

Table 5-4 Selecting baud rates by equipment type and access type

Note:

Newer revisions of the 551VST List 2, 551VST ML List 2, SIM,

and NC/E can be accessed in dial-up mode using the Hayes



protocol at either 1200 or 2400 baud with an external modem.

Existing revisions of the above products can be upgraded to this

capability with a firmware change.

The Enable Alarm Reporting option tells a node that alarm

messages should be sent to Access Manager either as they occur or when

the node is accessed.

Only a node that has alarm reporting capability can have this option set to

YES and then only if access to the node is through a direct connection,

modem, or ComDesign multiplexer. Access System equipment is also

compatible with the X.25 PAD (Packet Assembler Disassembler).

If access to the circuit elements in a node is through the ESF Facility Data

Link, set this option to NO.

The following types of nodes can report alarms:

■ 551VST List 2

■ 551VST ML List 2 without ASCII interface firmware
