Note:
This switch setting is applicable for a system which adopts Associated Channel Interoffice Signalling
(ACIS).
2.4 Digital PAD Setting
The PA-24DTR card is equipped with a mask ROM in which the following typical PAD patterns have been
already written. PAD value is determined by selecting a desired PAD pattern, which can be done by key
setting of the SW 58 (elements 4, 5, 6) on the card, and programming of the PAD...

3.1 Mounting HUB (PA-M96) in a PIM
Mount the HUB (PA-M96) card in an appropriate slot of a PIM as shown below. When the MAT is con-
nected via a HUB card, be sure to use a dedicated HUB for the Fusion link.
Note:HUB (PA-M96) can be mounted wherever in a PIM of any IMG stack. However, if your system is 1-IMG
type, mount the HUB in PIM0.

3.2 Mounting FCH (PA-FCHA) and DTI (PA-24DTR) Cards
Mount the FCH (PA-FCHA) and the DTI (PA-24DTR) card in appropriate slots in a PIM. Mount the two
cards in adjacent slots since these cards must be connected on the front connectors. Figure 4-8 shows an
example with the FCH and DTI cards mounted in PIM 1.

4.1 Connecting DTI-FCH Front Cables
Connect the furnished front cable to the connectors on the DTI and FCH cards. Use DTI and CN2 connec-
tors on the FCH and DTI cards respectively. Since an FCH card is equipped with one Handler circuit, a
maximum of five FCH cards can be connected to a DTI card. (See Figure 4-10.) However, if a DCH card
is also cascaded, a maximum of three FCH cards can be added to the DTI...

4.2 Connecting 10 BASE-T Cables
Figure 4-11 shows sample cable connections, where HUB (PA-M96) cards are provided in a dual configu-
ration and the FCH (PA-FCHA) card is located in PIM 1 (1-IMG system/IMG0). When HUB cards are pro-
vided in a dual configuration, the two HUB cards must be connected on each front edge connector using a
10 BASE-T cross cable. However, when dual LANIs (LANI-A and LANI-B) are used for each CPU, the...

4.3 10 BASE-T Connection Procedure
The pattern for 10 BASE-T cable connections may vary, depending on the system configuration (such as
number of IMG stacks or the mounting location/number of the FCH/HUB cards, etc.). According to your
system configuration, connect necessary Ethernet cables:
