Physical Description

QoS supports:  
•  Labeling IP level priority (ToS/Diffserv) for TDMoIP packets 
•  VLAN tagging and priority labeling according to IEEE 802.1p&q  for TDMoIP 

packets. 

The user can configure the ToS (Type of Service) of the outgoing TDMoIP packets. 
This allows an en-route Layer 3 router or switch, which supports ToS, to give 
higher priority to IPmux-1/1E TDMoIP traffic for delay-sensitive and secure 
applications. IPmux-1 allows you to configure the WHOLE ToS byte field, since 
different vendors may use different bits to tag packets for traffic prioritization. 
This also enables operation according to various RFC definitions (for example RFC 
2474, RFC 791). The user can also configure VLAN priority bits for  
Level 2 Priority. 

IPmux-1 maintains synchronization between TDM devices by deploying advanced 
clock distribution mechanisms.  
Available timing modes are: 
•  Loopback 
•  Adaptive 
•  Internal Clock 
•  External Clock.

IPmux-1E is a 1U high 19-in (IPmux-1 is a 1U high ½ 19-in), easy-to-install 
standalone unit. A rack mounting kit option is available (ordered separately).
