trunk CPs (except Tie Trunk CPs) can be connected to a three-way splitter cable (OR6016)
that concentrates the CP interfaces into one 25-pair cable. Up to two Tie Trunk CPs can be
connected to a two-way splitter cable (OR6015) that concentrates the CP interfaces into one
25-pair cable. Each splitter cable connects to an interface block at the TAE.
Cables are cut down or plug into the TAE blocks and plug into the telephone company
provided network interface (RJ21X or RJ2GX). Trunks and tie lines are cut down by the
Telco at the interface.
700A or 157B Blocks are usually used for the TAE connections (furnished by the installer).
