1-8 Physical Description
QoS
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.
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 in Section 1.3.
1.2 Physical Description
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).
Figure 1-7 shows a 3-dimensional view of IPmux-1 and IPmux-1E.
