APPENDIX D - CONNECTIONS TO MULTIRACK
The purpose of this appendix is to describe how to make connections to Comrex ACCESS MultiRack.
BRIC NORMAL CONNECTIONS
The Comrex ACCESS MultiRack allows users to make up to 5 separate AES67 connections. This feature allows
additional setup including the assignment of separate UDP ports for each MultiRack Instance. UDP 9000 is the
default port for BRIC Normal connections. Instance #1 on MultiRack will use the UDP 9000 port by default. Comrex
generally recommends End Users with MultiRack then use UDP 9002-9005 for instances #2-5 respectively, leaving
UDP 9001 open for Crosslock.
When making Remote Entries for MultiRack, each instance needs to be its own separate entry. For BRIC Normal
connections, this is done by entering the Public IP Address the MultiRack is behind followed by ":9000" for instance
#1, and ":9002", ":9003", ":9004, and ":9005" for instances #2-5 respectively. For example, creating a BRIC Normal
entry for instance #3 on a MultiRack would read: "<IP ADDRESS>:9003".
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 UDP 9001 can not 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
Note: Comrex Devices must be running at least Firmware version 4.5 to designate MAC Address suffixes when
making Manual Crosslock Remote Entries.
