A. Real-time Alarm and Trap Screens
The Cellworx NMIC provides real time alarm monitoring capabilities to an
External Management System (EMS) via SNMP traps through an Ethernet port on
the NMIC EIM. This scheme supports remote retrieval of NMIC collected data for
user manipulation and report creation via ftp using four simple file types. These
files are comma, space, or tab delimited and cover the following categories of
collected data: Alarm history, Accounting, PM data, and Network Data Collection.
The NMIC serves as an ATM domain operations interface provided on a Cellworx
STN shelf configured as a Gateway Network Element (GNE), generally located in
the CO or manned site. The NMIC can process 1.6K TFTP (Trivial FTP)/FTP
packets as well as 0.8Mbytes of data per second, serving as an FTP server for each
of the NE Shelf Controllers (SCs). The alarm history from each of the NE SC traps
is stored up to 24 hours for future queries. The NMIC sends an SNMP request to
the destined NE based on legitimate SNMP requests received from the EMS, and
discards all IP packets that are different from its IP address.
The SNMP MIB for ring management is ATM Forum network view M4 based. The
NE processes up to ten SNMP traps per second also.
GR-1248, [213] is supported. The NMIC supports the user identification,
authentication, system access control, resource access control, security log, and
security administration requirements as stated in GR-1248 [213]. The administrator
can configure the option of allowing the user to only perform SNMP get requests
and receive SNMP traps.
