IPmux-8/16 Ver. 6.00 Functional Description 1-13
Figure 1-10. IPmux-8/16 in External Clock Mode – E1/T1
E3/T3
Only IPmux-16 has E3/T3 ports.
This topology enables point-to-point connectivity; in Figure 1-11 both IPmux-16
units have direct E3/T3 connectivity. In this timing configuration both mesh and
star bundle connection topologies are supported.
Figure 1-11. IPmux-16 in Loopback Timing Mode – E3/T3
Single Source Clock Network
Figure 1-12 illustrates an application when a common clock is not available on all
the ends of the network:
• E1/T1 Device Configuration:
One of the E1/T1 devices connected to IPmux-8/16 (or E3/T3/CT3 connected
to IPmux-16) should work as the master clock while the other or others work
in loopback timing.
• IPmux-8/16 Configuration:
The IPmux-8/16 ports connected to the master clock device work in loopback
timing, while the far-end IPmux-8/16 units work in adaptive mode.
