Connecting And Disconnecting; Special Notes For Manual Crosslock Connections - Comrex ACCESS MultiRack Product Manual

connectIng And dIsconnectIng

Once the remote connection entry is completed in the Connections Tab, highlight the remote and select Connect.
When a connection is attempted, the State column in the connection table will change to reflect the progress of
the connection (Figure 43). If the connection fails, the reason for the connection failure will be shown in the State
column. When the remote connection succeeds, the encoder and decoder mode will be reflected in the Rx Status/
Tx Status column. To end a connection, highlight the remote and select Disconnect.

specIAl notes For mAnuAl crosslock connectIons

Manual CrossLock connections require special configuration options on both sides of the link. This primarily
involves programming the Switchboard ID for each unit (or primary Ethernet MAC address) into the outgoing
settings on the codec on opposite side of the link. This process for outgoing calls is described above. What isn't
mentioned is also important: the MAC/Switchboard ID of the outgoing unit must also be programmed into the unit
receiving the call.
Note that MultiRack instances #2-5 have special Switchboard IDs consisting of the primary Ethernet MAC followed
by a suffix (e.g. 00:01:0c:c0:78:19-4 for instance #4).
This is done by creating an outgoing connection describing the far-end unit, even if it is never actually used for
outgoing calls. In the case of this "dummy" entry, it's not actually important for the IP address field of the far-end
unit to be correct. The entry must be enabled for CrossLock operation and it must have the correct Switchboard ID/
MAC address of the far-end unit.
In the special circumstance where the default CrossLock port of UDP9001 cannot be used (e.g. several MultiRack
codecs sharing a single IP address), then manual CrossLock connections get extra complex. For more information on
these settings, refer to the Technote "Making CrossLock connections on non-standard Ports" on www.comrex.com.
