2. For each line/trunk and extension jack of each module, write the type of
jack (
X = extension; and L/T = line/trunk) and the associated logical ID,
keeping in mind the following:
■ Each 100D module is assigned 24 logical IDs, even though the
module has only 1 physical trunk jack.
■ Each 800 NI-BRI module is assigned 2 logical IDs per physical trunk
jack for a total of 16 logical IDs.
■ The 008 OPT module is assigned 12 logical IDs, even though the
module has only 8 physical extension jacks.
■ Power-failure transfer (PFT) jacks are not assigned logical IDs.
NOTES:
1. If the system will have one or more PFT telephones (maximum: 20),
indicate on the Control Unit Diagram the modules that will have PFT
telephones connected to their PFT jacks; write
PFT in the modules. A PFT
telephone can be connected to a PFT jack on a 400 LS, 400 GS/LS/TTR,
800, 800 GS/LS, 800 GS/LS-ID, 408, 408 GS/LS, or 408 GS/LS-MLX
module. Touch-tone PFT telephones must be connected to jacks with
touch-tone lines/trunks.
2. You need a ground-start button on a PFT telephone connected to a
ground-start trunk.
