or second Port Cabinet in the System. The TN748C is not required if
the cabinet is the third Port Cabinet in the System.

when no CallVisor ASAI functions are supported, TN570 is required for
CallVisor ASAl.
Provided as required.
The TN768 Tone Clock is required in Cabinet B of an EPN with duplica -
tion. The TN780 is required when connecting to an external Stratum 3
clock.
One always required.
Maximum of one per System. Mount in the Control Cabinet when pos -
sible.

Use TN465 in G3i-Global where administrable timers and 16 kHz PPM
are required.
Use TN479 in G3i-Global where a 24 volt limit or Japanese ring
cadence is required.

5. Using the hardware Configuration Layout record, assign circuit packs to available port
slots on all completed Port Assignment Records.
6. Determine how many ports are available on each type of circuit pack using Table D. If a
circuit pack contains less than eight ports, strike out (do not use) the unavailable slots on
the Port Assignment Record associated with that circuit pack.
Some of the forms you will be completing require port information. When completing such a form,
first determine the type circuit pack that is required. Next, obtain the Port Assignment Record
and select the next vacant port on the appropriate circuit pack. Then, complete the following Port
Assignment Record items as required:
Jack #— to be completed by the installation technician. Used to denote the physical location of
