A 10/100 BaseT Ethernet RJ-45 connector for access to a LAN, WAN or computer. This port is by default used for uplink / WAN connection.
The Mediatrix 4400 may also offer the option to use this connector as a remote power feeding over Ethernet as per 802.3af when the
network offers the capability.

Bypass Feature (
)
4402plus/4404plus Models
In the event of a power failure or network failure, the optional bypass feature permits users to make and receive calls even when the Mediatrix unit is not
operating.
The Mediatrix unit BRI 1 and BRI 2 connectors may either act as a SCN bypass. For instance, if you decide to connect a SCN line into the BRI 2
connector, you can use a BRI telephone connected into the BRI 1 connector to make calls. Furthermore:
The connector on which the SCN line is connected must be configured as a TE.
The other connector must be configured as a NT.
Refer to the Software Configuration Guide for more details on how to configure the line type.
During normal operation, the direct connection between the BRI 1 and BRI 2 connectors is switched out through commuting relays and both ports resume
normal functions. When power is removed from the Mediatrix unit, the relay setting is restored to a connected state and the SCN line can be used as an
emergency line. Consequently, a BRI telephone used on the other port is directly connected to this SCN line. When the power is restored, this
automatically removes the Bypass connection; this means that any ongoing call on the Bypass connection is terminated.
