ONNECTING
The AMU-912 supports up to three simultaneous TELNET connections. You can use either the SNMP or the
Screens Interface to manage the AMU-912. The logical connection over TELNET provides the same functionality
and interface as a locally connected craft port. However, only TELNET clients fully supporting the VT-100 emula-
tion can adequately provide access to the Screens Interface. There exists a number of possible physical configura-
tions to access one or more AMU-912s and each is described below.

TELNET Client

The AMU-912 supports all TELNET client application software complying with (RFC854) "The TELNET Protocol"
standard. Additionally, TELNET client applications providing full support for the VT-100 standard may be used to
remotely access the Screens and Screens MultiShelf interfaces. Known VT-100 compliant TELNET client
applications are:
• ProComm Plus 3.x, 4.x
• Reflection X 7.x
Packages that do not provide the full VT-100 emulation have unpredictable display results. The AMU-912 TELNET
Server supports the TELNET negotiation options:
• Suppress Go Ahead
• Will Echo

MS LAN

Accessibility of the Multishelf Local Area Network (MSLAN) is dependent upon its physical connections. An MSLAN
can support from one to a maximum or 24 AMU-912s on a single segment. There are two different methods for
connecting one or more AMU-912s to a MSLAN:
• The preferred/recommended method to connect an MSLAN consists of one or more shelves connected by
means of 10Base-2 cabling and connectors on their respective backplanes. Each end of the daisy-chained LAN
must be terminated using 50 Ω BNC-terminations.
• A second/alternative method to connect an MSLAN consists of one or more shelves connected to a network by
means of 10Base-T cabling to the front panel of the AMU-912 in a star configuration. In this method, the
10Base-2 connections on the backplane must NOT be used.
To remotely connect with the MSLAN, at least one AMU-912 on the segment must have a 10Base-T connection to a
user's network. With this type of connection, the AMU-912 must have a correctly configured IP Address and Subnet
Mask. You can access these values from
assigned for IP connectivity.
An MSLAN must NEVER be connected to a network via both 10Base-T and 10Base-2. The only
WARNING
recommended method for connecting the MSLAN to the user's network is via a 10Base-T
connection.
Refer to the following four distinct topographies described in the following sections. These topographies can be
created to allow or restrict remote access to an MSLAN.
