elements is connected in an NMS chain, the EM8000 may
be connected to the supervisory port of any one of the ele-
ments. This element can then route messages onto the NMS
chain to reach the other elements. The call on alarm (COA)
feature works through the supervisory port only.
The supervisory port is an independent serial interface into
the PRISM 3000 and plugging into it does not interrupt the
NMS port traffic. The supervisory port bit rate must be set
by the front control panel (refer to ‘System Utilities’,
Sec-
tion 3.8 on page 3 -10 ).
The physical connection is a 6-pin modular jack with the
following pinout assignments. The port is a serial RS232
DCE port configured for 8 bits, no parity, and 1 stop bit.

2.10.3 LAN SNMP Connection
The PRISM 3000 may be equipped with an optional Ether-
net or Token Ring interface for connection to the user’s
LAN (local area network). The unit’s SNMP (Simple Net-
work Management Protocol) agent can then be programmed
to take advantage of the centralized status monitoring and
alarm reporting capability of SNMP managed networks. The
LAN interface is connected to Slot 1 on the rear panel.
Ethernet: The Ethernet interface consists of a 15-pin
female AUI (attachment unit interface) connection compli-
ant with ISO/IEC 8802-3 standards (formerly IEEE 802.3).
