Connecting Electrical Interfaces through the
TPU
The type of cable used to connect the I/O modules to the TPMs depends on the
type of I/O module being protected, as follows:
|
For PIM2_21s, 2 x 50 to 1 x 100 SCSI cables are supplied, to be connected
from four different PIM2_21s to connectors PIM2_21 #1, PIM2_21 #2,
PIM2_21 #3, and PIM2_21 PROTECT at the bottom of the TPM2_3.
Multipair traffic cables are connected to the DDF#1, DDF#2, and DDF#3
connectors at the top of the TPM2_3.
The connection between TPM2_3s and PIM2_21s is shown in the following
figure.
Connections are between a connector in the TPM and the corresponding
module in the shelf, where “P” denotes protection and 1, 2, and 3 are for
reference purposes.

| For PIM345_3 or SIM1_4/E modules, the supplied cables enable
connection from the DIN 1.0/2.3 connectors on the I/O module to the 8W8
MAIN and PROTECT connectors at the bottom of the TPM-H_1. The
traffic coaxial cables are connected to the OUT/IN connectors at the top of
the TPM-H_1. These connections are shown in the following figure.
