2.1.5 BUS Cable Connection

(1)Cable connection between BUS Card and the DAIA Card

Connect the DAIA card to the BUS card by the RMT PCM-0.3 CA and 17-TW-0.3 CONN CA-A, as shown in Figure 3-9.

Note: Up to three DAIA cards can be connected directly by a daisy chain connection on one PIM. If two or three DAIA cards are mounted on one PIM, the 17-TW-0.3 CONN CA-A is required. When the system is more than one PIM configuration, the DAIA cards must be mounted on the first/last PIM due to the number of connectors of a BUS card.
