Chapter 1. System Overview and Modes of Operation
AMCU User Interfaces
The AMCU may be accessed in three ways:
•
An SNMP manager, such as Hewlett Packard's OpenView
accesses all Management Information Base II (MIB-II) parameters supported by the
SNMP agent, and all the DS1 MIB values supported by the current D/I Mux III
software. (See MIB-II and DS1 MIB in Appendix H.) Special configuration screens
allow the user to branch to either the LAN, and login parameters, or to the standard
screens supported by the CCU.
•
A local terminal (all values available by local terminal will also be available via the
Telnet connection except IP address and subnet mask) - The local terminal is an RS-
232 serial connection. The user must use the local terminal to enter an initial IP
Address and subnet mask. Using the local terminal will also lock out a Telnet
session. However, a keyboard idle timer can disconnect the serial connection and
allow a Telnet session.
•
A Telnet session - A Telnet session can be connected over Ethernet 10Base-T as a
virtual terminal (VT) connection, normally providing VT-100, or VT-220 functionality.
A Telnet client is required by the user to make this connection and, once connected,
the Telnet screen presentation is that of a serial connection.
