• Manufacturer Part Number: TISP61089BSD
• Description: Dual Forward-conducting P-gate Thyristors Programmable Overvoltage Protectors
• Manufacturer: Bourns, Inc.

This test, Table 8, is for network equipment ports that do not serve outside lines. For standard plugable premise wiring, the wiring simulator
fuse shall be used for testing. Where direct wiring occurs, the simulator shall consist of a length of the wire used wrapped in cheesecloth. The
equipment fails if a hazard occurs or a wiring simulator open circuit occurs or the cheesecloth is damaged.
This test, Table 7, is for network equipment located on the customer premises. The purpose is to ensure that the feed wiring does not become
a hazard due to excessive current. This testing is similar to the Section 4.5.11 testing. If the equipment is directly wired, the wiring simulator
described in Section 4.5.11 is replaced by a one-foot section of 26 AWG wrapped in cheesecloth. The equipment fails if an open circuit occurs
or the cheesecloth is damaged. Table 7 shows the test conditions for this section. Columns 7 and 8 show the prospective currents using R
values of 25 Ω and 40 Ω. For the TISP61089BSD to survive, the series overcurrent protection to operate before the TISP61089BSD current-time
ratings are exceeded.
