Breakout box and cables — The breakout box provides a standard RJ-45 telephony interface for E1
and T1 PRI systems. It interfaces to a maximum of 16 cables. For each MA-16 shipped with the 8112
server, we include 16 telephony cables and two trunk interface cables (50-pin Amphenol connectors)
to connect each MA-16 to the breakout box; for each MA-4 shipped with the 8112 server, we include
four telephony cables and one trunk interface cable (50-pin Amphenol connector) to connect each
MA-4 to the breakout box.
