ACCULINK 315x CSU
Alarm Message Capability
The CSU can be attached, either locally or remotely, to
an ASCII terminal or printer to display or print alarm
messages. Alarms can also be displayed on a PC that is
using a terminal emulation package.
Front Panel Emulation
The CSU offers functionality through Front Panel
Emulation software that is similar to that provided by the
CSU front panel. The functionality of the front panel is
available by clicking on the function keys with the mouse
rather than by pressing keys from the actual front panel.
Integral Modem
The standalone CSUs contain an integral low-speed
(2400 bps), V.22bis dial modem that enables
communication with remote devices such as another 3150
CSU, an ASCII terminal or printer, or a PC running the
3100 Series Front Panel Emulation software.
Async Terminal Interface Support
The DSU/CSU can be configured and managed from
an asynchronous (async) terminal. The async terminal's
full screen display uses a menu hierarchy similar to the
DSU/CSU's front panel. You can perform device
management and configuration operations as if you are
using the DSU/CSU's front panel, but you do not have the
limitation of the 2-line, 16-character LCD.

Telnet Access
Remote async terminal operations can be performed
using Telnet access. Telnet is a Transmission Control
Protocol/Internet Protocol (TCP/IP) service that supports
a virtual terminal interface.
SNMP Management Support
SNMP is a network management protocol that is used
to monitor network performance and status, and to report
alarms (i.e., traps). To function, SNMP requires a manager
consisting of a software program housed within a
workstation or PC; an agent consisting of a software
program housed within a device (e.g., the CSU); and a
Management Information Base (MIB) consisting of a
database of managed objects. The CSU can be managed
by any industry-standard SNMP manager.
Two link layer protocols, Point-to-Point Protocol (PPP)
and Serial Line Internet Protocol (SLIP), are supported for
connection to an external SNMP manager or network
device (e.g., a router).
The SNMP manager or network device can be directly
connected to the communications (COM) port. An
external LAN Adapter can be connected to either the
COM port or the auxiliary (AUX) port to provide Ethernet
connectivity. Also, the CSU can be daisy chained together
by connecting the COM port of one device to the AUX
port of the other, providing SNMP connectivity.
The SNMP management system can communicate to
the CSU remotely through the Facility Data Link (FDL).
