Check to see that the trunk has been connected to an RJ21X (for a
DID trunk) or RJ2GX (for a tie trunk) network interface by the
telephone company.
If the trunk is connected to an existing network interface, determine
the correct wires on the connecting cable. Cut them down to the
correct position on the TAE connecting block, following the
procedures under “Install Cross-Connect Equipment” in Section 2.
If the trunk is connected to a new network interface, connect it to the
TAE following the procedures under “Install Cross-Connect
