2. Installation
Making Signal Connections
• XPT 3 — The crosspoint card installed in the center-bottom slot: ‘C’.
• XPT 4 — The crosspoint card installed in the bottom slot: ‘D’.
Within each ‘XPT’ set, connections are labeled: ‘OUT 1’, ‘OUT 2’ and ‘OUT 3’, and ‘IN 1’, ‘IN 2’
and ‘IN 3’. Each ‘OUT’ and each ‘IN’ correspond to a segment of memory on the crosspoint card.
For more information, see
Frame Expansion on page 29. To connect two router frames together,
you connect the ‘OUT’ connection on one router (Router 1) to the ‘IN’ connection on a second
router (Router 2). One ‘OUT’ is connected to one ‘IN’ for each crosspoint card, as shown in
Figure 2-16 on page 55.
The signal expansion connections use 75 Ω BNC connectors and Belden 1694A cable.
How to make expansion signal connections
1 Locate the signal expansion connections on the rear of the router, as shown in Figure 2-15.
Figure 2-15. Signal Expansion Connections (Rear View)
Note The routers should be placed in close proximity; the cable has a maximum length
of 100
feet (30 m).
