4 Insert the TP-260 board into the chosen PCI slot. Ensure that the front panel (bracket) of
the TP-260 board fits correctly into the opening in the rear panel of the PC's chassis.
Also, check that the edge of the PCI retainer bracket fits correctly into the PC’s PCI slot.
5
Secure the front panel of the TP-260 board into the chassis frame with a standard screw.
This also ensures chassis ground to the TP-260 board.
6
Replace and secure the PC's cover.

TM
operating systems, the PC prompts that new hardware has been
found. The driver for the TP-260 is found in the supplied software package
(
260_UNSeries.inf ).
Note that since the TP-260 PCI gateway operates independently and relies on the host’s
PCI only for its power, the driver is only used to prevent the Found new Hardware Wizard
to reappear each time the host PC restarts.
Cabling the TP-260
To cable the TP-260:
1 Connect the TP-260 E1/T1 interfaces to your E1/T1 trunks by using the four supplied TP-
260 E1/T1 cable splitters (shown in
Figure 31 ). Connect a splitter to each of the four RJ-
48 connectors labeled Trunks 1/5, 2/6, 3/7 and 4/8 on the TP-260 front panel. Each
splitter distributes each RJ-48 connector into two separate connectors (wired according
to
Figure 15 ): the first connector (labeled 1/4) on each splitter supports each of the first
four trunks, the second connector (labeled 5/8) on each splitter supports each of the last
four trunks.
The TP-260 E1/T1 cable splitter is part of the 8-span TP-260 product and is PSTN
certified. When using a
non -3Com E1/T1 cable splitter, 3Com cannot guarantee
compliance with PSTN homologations.
