2.22 The SX-200 Interconnect Card (Figure 2-5) provides a direct
connection between the consoles (J13, J14 and J15) and the
shelf backplane (P16 and P17). This board also contains the console
fuse for protection of the console. Directly opposite the fuse is the
RS-232 printer port J302. For a complete description of this port, see
Section MITL9105/91 lo-096-450-NA and Table 2-5. Plugs P301 and
P303 are the maintenance panel connector and the power supply
out-of-tolerance monitor, respectively. All power for the Interconnect
card is supplied through the power supply terminal block TB301 on the
board. Plugs J13, J14 and J15 are the console plugs. Plugs P16 and P17
provide interconnection between the Interconnect card and the shelf
backplane. Plugs P18 and P19 provide a connection between the Inter-
connect card and the Cross-Connect Field. P18 carries Night Bell Con-
tacts, Music on Hold, Tip and Ring for RMATS and Paging access
circuitry. P19 carries Tips and Rings for the card shelf slots 13 and 14.
