SCM Overview
Verilink SCM 1-7
Figure 1-4 System Controller Module in a Multiple Application Network
Craft Interface
Port
The Craft interface supports up to four simultaneous sessions:
• One direct local connection
• Up to three Telnet sessions over Ethernet or SLIP. To prevent
lockups of the Telnet server, it is recommended that only one
Telnet session be used during periods of heavy alarm activity.
Ethernet connectivity conforms to DIX and IEEE standards and is
supported through the AAUI connector port on the rear panel and a
provided transceiver with both 10BaseT and 10Base2 ports.
SNMP Clients
The SCM supports SNMP-based clients such as Node Manager and
HP OpenView™, Manager of Managers (MoMs), over Ethernet or
SLIP.
Adherence to ITU/ANSI/IETF specifications is required to ensure
compatibility and interoperability with complimentary SNMP
products. For more information on SNMP and Verilink products see
the SNMP Management Manual.
The SCM supports AS2000 node configuration by allowing
appropriate values to be assigned to and collected from the
configuration management objects defined in the supported MIBs.
Management application protocols such as Node Manager make use
of the MIBs.
The SCM 3000 does not support MIB II.
