Access Manager 2000 User Manual

The modes of access for near-end nodes are standard implementations of

RS-232 interface methods, that is, direct, daisy-chained, through a

statistical multiplexer, or by modem. The mode of access for far-end

nodes is through the ESF Data Link through the near-end node access.

Since the functional specifications of the various Verilink network access

systems differ, Access Manager presents a different set of menus for the

two different types of nodes.

The two basic types of nodes are:

■ AS2000 type node (includes Access System 2000 and ConnecT1

Plus network management systems). ConnecT1 Plus is a low-cost

implementation of AS2000 hardware available in a dual-line shelf

configuration only

AS2000 and ConnecT1 Plus nodes can have up to four shelves per

node. ConnecT1 Plus nodes have only dual-line shelves. AS2000

nodes can have a combination of dual-line and multiline shelves.

However, of the four possible shelves in an AS2000 node, no more

than two can be multiline shelves.

■ 551VST type node (551VST type single-line nodes; SIM, NC/E,

551VST ML List 1, and 551VST ML List 2 multiline nodes).

This manual presents information mainly through menu descriptions.

Access Manager has two types of menus:

■ The AS2000 type of menus that reflect the functions of AS2000 and

ConnecT1 Plus Nodes.

■ 551VST type menus for the other types of nodes.

The various configurations for these nodes are described in the following

section.

Single-Line Nodes

The single-line nodes with which Access Manager 2000 interfaces are as

follows:

■ 551VST List 1/A CSU

■ 551VST List 1/B CSU

■ 551VST List 2 CSU

1 2 ... 30 31 32 33 34 35 36 37 38 39 40 ... 399 400
