address and provides information to units in the same
Switchboard fleet that are also online. Any online units
will automatically populate in the Connections tab,
bypassing the need to know IP addresses of the units.
What is CrossLock?
CrossLock describes a new reliability layer that gets
established between Comrex devices in advance of a
connection. This layer takes the form of a Virtual Private
network (VPN) between the devices.
In addition to carrying the audio media, CrossLock

allows lots of other information to be shared between the
endpoints, including information about network quality
and far-end delay settings. This provides for much better
delay management on either end of the link.
Creating a CrossLock Connection

To set up a CrossLock connection, you must know the
MAC addresses of the units on both ends of the link.
This is input on the “Store New Remote” pop-up in the
MAC Address field. You will also need to check Use
←
Crosslock to Connect. Enter in a remote name for the
connection, the IP Address of the unit you are calling,
the audio connection password (default is blank) and
choose a factory profile to use.
In addition, the codec receiving the connection must

have a similar entry made, with the MAC Address of the
calling unit populated.
NOTE: This is important. The receiving unit must

have an outgoing connection programmed into its
address book, containing the MAC address of the
calling unit, even if that entry is never used for
outgoing calls.
Viewing CrossLock Statistics
When a CrossLock connection becomes active, the

CrossLock stats are available to view on the CrossLock
tab. The stats are a very powerful tool to diagnose the
quality of connections as well as manage the delay
settings during the connection.
To learn more about the CrossLock stats tab, consult

your product manual.
