Communication Server 1000M and Meridian 1 Large System Installation and Commissioning
c. Connect a #24 (or larger) AWG wire from the ground (GND)
connection on the auxiliary power supply to the PFTU termination
area on the MDF.
d. Connect a second #24 (or larger) AWG wire from the GND
connection on the auxiliary power supply to the Large System alarm
termination area on the MDF.
e. Plug in the A0367916 auxiliary power supply.
— If a UPS is used, you must plug the power supply into an
auxiliary output on the UPS.
— Without a UPS, plug the power supply into an outlet in the
equipment room.
6 For DC-powered systems, power the PFTU from the fused low-current
auxiliary power outputs on the DC power system. One 1.33 A fuse
supports up to six PFTUs.
End of Procedure
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.
Procedure 14
Connecting trunks and telephones
1 For each telephone assigned to the PFTU.
• Connect the tip and ring of the line card to the first pair of the
assigned PFTU.
• Connect the tip and ring of the telephone to the second pair of the
assigned PFTU.
