Four BCM50 main units, the BCM50a, BCM50ba, BCM50e, and BCM50be, have a Router card.
On a BCM50a and BCM50ba main units, the WAN port is an RJ-11 port. On a BCM50e and
BCM50be main units, the WAN port is an RJ-45 port.
The figure BCM50a,BCM50ba, BCM50e, BCM50be main unit WAN ports on page 211 shows
the WAN ports for the BCM50a, BCM50ba, BCM50e, and BCM50be.
