SYN/1
Second-from-right LED in the module. In the Access Point Module or Backhaul timing
master, as in a registered Subscriber Module or Backhaul timing slave, this LED is
continuously lit to indicate the presence of sync. In the operating mode for a Subscriber
Module or Backhaul timing slave, this LED flashes on and to indicate that the module is
not registered. In the aiming mode for a Subscriber Module or a Backhaul timing slave,
this LED is part of a bar graph that indicates the quality of the RF link.
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.
TCP
Alternatively known as Transmission Control Protocol or Transport Control Protocol.
The Transport Layer in the TCP/IP protocol stack. This protocol is applied to assure that
data packets arrive at the target network element and to control the flow of data through
the Internet. Defined in RFC 793. See
http://www.faqs.org/rfcs/rfc793.html
tcp
Transport Control type of port. The system uses Port 3306:tcp for MySQL® database
communications, Port 9080:tcp for SSE telnet communications, and Port 9090:tcp for
Engine telnet communications.
TDD
Time Division Duplexing. Synchronized data transmission with some time slots allocated
to devices transmitting on the uplink and some to the device transmitting on the
downlink.
telnet
Utility that allows a client computer to update a server. A firewall can prevent the use of
the telnet utility to breach the security of the server. See
http://www.faqs.org/rfcs/rfc818.html
http://www.faqs.org/rfcs/rfc854.html
http://www.faqs.org/rfcs/rfc855.html
Textual
Conventions MIB
Management Information Base file that defines system-specific textual conventions. See
also Management Information Base.
Time of Last
Transaction
A field in the data that the cmd show esn command generates from data in the SQL
database in the Bandwidth and Authentication Manager (BAM) server. This field
identifies the time of day of the most recent authentication attempt by the SM.
Expressed in the database output as TLT.
TLT
Time of last transaction. A field in the data that the cmd show esn command generates
from data in the SQL database in the Bandwidth and Authentication Manager (BAM)
server. This field identifies the time of day of the most recent authentication attempt by
the SM.
TNAF
Total number of authentication requests failed. A field in the data that the cmd show esn
command generates from the SQL database in the Bandwidth and Authentication
Manager (BAM) server. This field indicates how many times the SM (identified by ESN
in the related data) attempted to authenticate but was denied by BAM.
