Connecting trunks and telephones

The "ground start" feature on 500/2500-type telephones connected to CO
trunks requiring a ground start condition is not required. Automatic ground
start is performed by the PFTU. However, rotary dials (dial pulse) are
required on telephones assigned to trunks that are not equipped to recognize
tone pulses (touch tone).
See the PFTU documentation for MDF cable terminations for telephones and
trunks associated with the PFTU. If the connections are not designated on the
connecting blocks, mark the blocks as shown in the documentation or install
the appropriate designation strips.
