3.3.4.1 Connecting the E1/T1 Trunk Interfaces
The TP-260 provides four RJ-48c ports for supporting up to eight E1/T1 spans.
¾ To cable the TP-260, take these 2 steps:
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 the figure below). 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 the figure below): 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.

Note: The TP-260 E1/T1 cable splitter is part of the 8-span TP-260 product and is
PSTN certified. When using a non-AudioCodes E1/T1 cable splitter,
AudioCodes cannot guarantee compliance with PSTN homologations.
