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

This test is for network equipment ports that do not serve outside lines. Table 3 shows the 2/10 tests used for this section. Dedicated intra-
building ports may use an R
and 11 show the resultant currents for R
2x120 A and the TISP61089BSD will survive these tests.
Equipment that allows unacceptable current to flow during power faults (Figure 16) shall be specified to use an appropriate current-limiting
protector. The equipment performance can be determined by testing with a series fuse, which simulates the safe current levels of a telephone
cable. If this fuse opens, the equipment allows unacceptable current flow and an external current-limiting protector must be specified. For
acceptable currents, the equipment must not allow current flows for times that would operate the simulator. The wiring simulator fuse current-
time characteristic shall match the boundary of Figure 16. A Bussmann MDQ-1
