APPENDIX C - INformAtIoN for It mANAgErs
The purpose of this appendix is to describe all open ports and services available on the Comrex BRIC-Link.
The Comrex BRIC-Link is a device designed to move real-time, wideband audio over IP networks. The main network
interface is 1000BaseT-Ethernet. The device contains an optimized version of Linux kernel. The IP parameters are
set by a computer on the local LAN using a proprietary broadcast UDP protocol.
Comrex provides Device Manager, a Windows- or MAC-compatible application, on the included CD or available on
our website at www.comrex.com, to perform this function on the local computer. Once the unit is powered on your
BRIC-Link, you have five minutes before this function is disabled.
IP parameters can also be changed online using the Network Manager in the Web GUI Main Menu. Updates to the
system are provided by a custom online updater utility. This update process is password-protected and requires
access to TCP 80 and TCP 8081. In addition to the password protection, the update data itself must have a valid
cryptographic signature from Comrex, or else it is rejected.
