Extensive Statistics Gathering. Provides a complete view of the network’s
and each data port’s performance through the statistical data collected from
those interfaces to assist in determining the duration of a condition or event.
— A total of 96 intervals (24 hours) of user and Telco statistical data is kept,
seven per screen page, over a 24 hour period, in 15-minute intervals.
— A total of 32 intervals (8 hours) of Synchronous Data Port statistical data
is kept, over an 8 hour period, in 15-minute intervals.
— Quick and easy access to any of the 96 sets of statistics is provided by
selecting a specific interval or occurrence timeframe. (Specifying an
occurrence timeframe is useful when you know about what time a
specific event occurred.)
— You can select a set of statistics to display at the following times:
following an event, preceding an event, immediately preceding and
following an event, or only those statistics that occurred at or after the
event that is the specified interval or time.
— Statistics collected measure or count the following: errored, unavailable,
severely errored, and bursty errored seconds, as well as controlled slip
seconds and loss-of-frame counts. In addition, yellow alarm, loss of
signal, excessive error rate, frame-synchronization bit error, and
line-code violation counts are kept for each 15-minute interval.
— The worst interval for each statistic is provided as an additional aid in
selecting statistical information surrounding trouble spots.
Configuration Upload/Download and Software Download Capability.
Provides quick, cost-effective software upgrades, and quick transfer of
configuration options to and from nodes using a standard file transfer protocol
(FTP).
Security. Provides multiple levels of security, which prevents unauthorized
access to the unit.
Security can be controlled by:
— Disabling any form of access to the unit.
— Requiring logins (login ID/password/access level combinations), with
three access levels to select from: read-only, limited-access, and
full-access.
— Enabling SNMP management, and specifying a community name and
access level Read or Read/Write.
— Enabling SNMP management, and specifying the IP addresses of only
selected NMSs.
Redundant power supply. Redundant load sharing supply (both AC and DC
versions available) for 5-slot housing. Protects the system from a service
outage if one power supply fails.
Wall-Mount Bracket. Allows one 5-slot, or up to two 2-slot housings to be
mounted on a wall.
