Term
Definition
SNMP
See Simple Network Management Protocol, defined in RFC 1157.
SNMPv3
SNMP version 3
SNMP Trap
Capture of information that informs the network monitor through
Simple Network Management Protocol of a monitored occurrence
in the module.
Static IP Address
Assignment
Assignment of Internet Protocol address that can be changed only
manually. Thus static IP address assignment requires more
configuration time and consumes more of the available IP
addresses than DHCP address assignment does. RFC 2050 provides
guidelines for the static allocation of IP addresses. See
http://www.faqs.org/rfcs/rfc2050.html
. See also DHCP.
Subnet Mask
32-bit binary number that filters an IP address to reveal what part
identifies the network and what part identifies the host. The
number of subnet mask bits that are set to 1 indicates how many
leading bits of the IP address identify the network. The number of
subnet mask bits that are set 0 indicate how many trailing bits of
the IP address identify the host.
Subscriber
Module
Customer premises equipment (CPE) device that extends network
or Internet services by communication with an Access Point
Module or an Access Point cluster.
Sustained Data
Rate
Preset rate limit of data transfer.
Switch
Network element that uses the port that is associated with the
physical address of another to pass data to only the intended
recipient. Compare to Bridge and Router.
SYN/1
Second-from-right LED in the module. In the Access Point Module
or in a registered Subscriber, this LED is continuously lit to
indicate the presence of sync. In the operating mode for a
Subscriber Module, this LED flashes on and to indicate that the
module is not registered.
Sync
GPS (Global Positioning System) absolute time, which is passed
from one module to another. Sync enables timing that prevents
modules from transmitting or receiving interference. Sync also
provides correlative time stamps for troubleshooting efforts.
