THGm (Ten/Hundred/Gigabit module)
A hardware device available from Finisar that allows the capture/transmit of net-
work data at full line rate and supports real-time monitoring functions for 10/100/
1000 Ethernets. The THGm card is for use with 1000BASE-SX, 1000BASE-LX,
and potentially other types of gigabit networks. The 1000Mbps network interface
for THGm is a removable G-BIC interface connector. THGm also supports 10/100
copper-wire networks. The 10/100 copper-wire network interface is an RJ45 con-
nector.
THGnotebook (Ten/Hundred/Gigabit notebook)
Portable undercarriage unit with one or two THGm analyzer cards designed to oper-
ate with a high-performance notebook computer. Connection to the notebook PC is
via PCI bus expansion. THGm devices in a THGnotebook can by accessed locally
or remotely by Surveyor software which provides the tools to diagnose, trouble-
shoot, and monitor any full or half-duplex 10/100 Ethernet copper or Gigabit Ether-
net fiber-optic network. THGp is often used in environments where a robust
portable analyzer is needed.
THGp (Ten/Hundred/Gigabit portable)
A Dolch PC-based portable network analyzing, troubleshooting, and monitoring
system available from Finisar. THGm devices in a THGp can by accessed locally or
remotely by Surveyor software which provides the tools to diagnose, troubleshoot,
and monitor any full or half-duplex 10/100 Ethernet copper or Gigabit Ethernet
fiber-optic network. THGp is often used in environments where a robust portable
analyzer is needed to analyze protocols such as IP, IPX, or iSCSI.
THGs (Ten/Hundred/Gigabit system)
A network analyzing, troubleshooting, and monitoring system available from
Finisar. THGs can by accessed locally or remotely by Surveyor software and pro-
vides tools to diagnose, troubleshoot, and monitor any full or half-duplex 10/100
Ethernet copper or Gigabit Ethernet fiber-optic network.

A counter that records events where the Token Ring Active Monitor does not detect
a token.
Total Tx Collision Counter
A counter showing the total number of collisions that have occurred when attempt-
ing to transmit.
Traffic
Transmitted and received frames or packets.
