12.9. AI-900TI Tie-Line Interface Card Exchange Interconnection

Up to 16 exchanges can be tie-line interconnected using the AI-900TI card.

[Connection]

To interconnect the exchanges, use 2 twisted pair cables for voice lines, and a 2-core shielded cable for data lines. A maximum of 4 voice lines can be connected. Refer to the following table for the maximum recommended length for each cable type between exchanges.

(As to the cable connection, see the figure on the next page.)

Cable type	AWG24 (0.52 mm)	AWG22 (0.65 mm)	AWG20 (0.82 mm)
Distance	0.6 km	1 km	1.5 km

[Termination resistance setting]

When interconnecting three or more exchanges, change the SJP10 connection on each card as shown below, with the exception of the cards in the rightmost and leftmost exchanges.
