Before making the electrical connections, fold the
chassis down to expose the backplane by following
these steps:
1. Lock the right knob, located on the side of the
assembly, by pulling the knob out and rotating
counter-clockwise until it has locked open. See
Figure 2 for an illustration.
2. With the right knob locked open, pull the left
knob outwards and rotate the chassis to the down
position. Release the knob allowing the chassis to
lock into place.
3. Using a small phillips head screwdriver, remove
the four (4) back panel screws and remove the back

4. Make appropriate connections outlined in the
following sections.
5. After the electrical connections have been made,
route all wiring through the semi-circle opening in the
back panel and secure with four (4) screws.
6. Route cable ties (provided) through the cable tie
holes on the right side of the assembly (see Figure 2)

edge connectors, (1) three-terminal barrier strip, (1)
two-terminal barrier strip, and (1) female DB-9
connector. The 50-pin male amphenol connector
interfaces with the T/R and T1/R1 connections for
each of the 10 channel slots. The (13) 36-pin card
edge connectors are used for BR1/10 common
equipment and channel units. The three-position
terminal strip, labeled JP16, supplies power
connections. The two-terminal barrier strip, labeled
JP18, is for future enhancements.
