The circuit definition is also used by Access Manager 2000 during data
analysis. This allows you to access the data stored in both circuit elements
by the associated circuit name. The circuit definition is also used during
the configuration of a far-end CSU through the ESF Data Link.
A route consists of the two network circuit elements at DS1 network
circuit end points as accessed by Access Manager. For Access Manager, a
circuit and a route are functionally equivalent.
Access Manager Connections
Access Manager supports five types of network management ports. These
connect Access Manager to the devices it monitors. This information is
used in Chapter 4, Configuring Access Manager when configuring the
Comlines of the host PC.
■
Direct-connect port. This port can be:
• Hardwired to the network device.
• Connected through a pair of full-time (dedicated) modems using
a dedicated facility.
• Connected by a dedicated port into a multiplexer and conveyed
in the multiplexer’s payload.
■
Remote dial port. The remote dial port can dial-out and receive
dial-in calls from network devices. This port uses the Hayes
 AT
command set at 1200 or 2400 baud.
■
Remote dial-in port. This type of port can only answer dial-in calls
from network devices (normally used with INWATS lines).
■
Routing port. The routing port is designed to connect to a routing
multiplexer such as a ComDesign RS2000 Statistical Multiplexer.
Multiple network devices may be connected through this type of
multiplexer.
■
Serial device interface. This is a serial output-only port with no
flow control. Sends alarm messages to a printer or to another
computer using the Accumaster protocol.
An optional external Hayes  -compatible modem uses the auto-dial/auto-
answer feature to automatically forward changes in the status or alarm
conditions of the near-end or far-end CSUs to a central management site.
