Note 1:
64Kbps is used for T1 or E1 interface.
56Kbps is used for T1 interface with bit stealing.
48Kbps is used for T1 interface with both bit stealing and Zero Code Suppression (or Bit 7 Stuffing).
Note 2:When n is bigger than 1, Time Slot Sequence Integrity (TSSI) must be guaranteed at the network side.
Note 3:The following is an example key setting when n = 2.
SW11-1 = ON
SW11-2 = ON

Note:
This switch setting is applicable for a system that 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 with the selection of 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 data by the ARTD
command - CDN = 30 (PAD). Refer to Ta b l e  4 - 5 for the PAD patterns and ARTD data.
Note:Stands for 3[dB] GAIN.

3.1 Mounting HUB (PA-M96) in a PIM
Mount the HUB (PA-M96) card in an appropriate slot of a PIM as shown in Figure 4-7. When the MAT is
connected via a HUB card, be sure to use a dedicated HUB for the Fusion link.
Note:HUB (PA-M96) can be mounted anywhere in a PIM of any IMG stack. However, if your system is 1-IMG
type, mount the HUB in PIM0.

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
connectors 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 4-9.) However, if a DCH
card is also cascaded, a maximum of three FCH cards can be added to the DTI card. (DCH is equipped with
two Handler circuits per card.)
