1-8 Overview IPmux-8/16 Ver. 6.00
Two network topologies are supported:
• Star (point-to-multipoint): Multiple remote locations transport one bundle
each to a central site that is capable of grooming the bundles into its E1 or T1
channel (see
Figure 1-7).
• Mesh: Any-to-any connectivity is supported at the bundle (DS0) level (see
Figure 1-8).
Internal Cross-connect
IPmux-8/16 allows for internal cross-connect of bundles between its E1/T1/CT3 ports.
QoS
QoS support:
• Labeling IP level priority (ToS) for TDMoIP traffic
• VLAN tagging and priority labeling according to IEEE 802.1 p&Q.
You 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-8/16 traffic for delay-sensitive and secure applications.
IPmux-8/16 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-8/16 maintains synchronization between TDM devices by deploying
advanced clock distribution mechanisms.
Available timing modes are:
• Loopback
• Adaptive
• Internal
• External (only for IPmux-16).
Standards
IPmux-8/16 follows the standards: G.703, G.704, G.706, G.823, ANSI T1.102,
ANSI T1.403, Bellcore GR-499, TR-AT&T62411, G.824, IEEE 802.3, IEEE 802.3D,
IEEE 802.1 p&Q.
Power
IPmux-8/16 can be ordered with dual redundant AC or DC power supplies.
IPmux-16 only
The following features are for IPmux-16 (not present in IPmux-8):
• External clock
• E3/T3/CT3 ports
• Out-of-band management via CONTROL ETH port.
