1-8 Physical Description
Timing
IPmux-1 maintains synchronization between TDM devices by deploying advanced
clock distribution mechanisms.
Available timing modes are:
• Loopback
• Adaptive
• Internal clock
• External clock.
For more details, see Timing Modes below.
Bundle Redundancy
IPmux-1/1E features a bundle redundancy capability. This feature enables the user
to backup the TDMoIP® traffic in case of fault at the bundle connection level
and/or the TDM level. This feature permits the user to set a different path for the
primary bundle and for the secondary bundle (different IP networks, different
links, different IPmux units, etc) and thus rely on two routes, which are not
influenced by the same faulty IP/Ethernet conditions. The following redundancy
modes are supported:
• 1+1: Both the primary and secondary bundles transmit TDMoIP traffic, but
only the active bundle receives TDMoIP traffic, while the redundant bundle
ignores the Rx path.
• 1:1: Only one bundle transmits and receives TDMoIP traffic while the
secondary bundle is kept on hold.
1.2 Physical Description
IPmux-1E is a 1U high 19-inch (IPmux-1 is a 1U high 8.5-inch), easy-to-install
standalone unit. An optional rack mounting kit option is available.
