RAD Data comm IPmux-1 - Manual (Page 17)

IPmux-1/1E Installation and Operation Manual Chapter 1 Introduction
Overview 1-9
IPmux E1/T1 working opposite IPmux-1E with BRI ports should work in Fractional
E1/T1 mode (no CAS). When working opposite IPmux-1E with FXS, use E1/T1 CAS
mode.
QoS
QoS support:
• Labeling IP level priority (ToS) 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 you to work 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.
