IPmux-24 Ver. 1.5 Configuring IPmux-24 for Operation 4-17
4.2 Configuring IPmux-24 for Operation
The recommended operation configuration procedure for IPmux-24 includes the
following stages:
1. Defining system clock.
2. Configuring IPmux-24 interfaces (Ethernet, E1, T1) at the physical level.
3. Creating bundles by allocating timeslots to them.
4. Connecting bundles by directing them to remote device.
Setting Device-Level Parameters
At the device level, you have to configure the system clock to provide a single
clock source for E1/T1 links of the device and a ring application to protect the
Ethernet transmission path.
Configuring the System Clock
IPmux-24 system timing mechanism ensures a single clock source for all TDM links
by providing the master and fallback clocks. If the system clock is locked to one
of the IPmux-24 TDM links, it is necessary to define clock source (adaptive or
loopback). See
Configuring the E1 TDM Interface for details.
³ To configure the system clock:
1. From the System menu, select System clock.
The System clock menu appears (See
Figure 4-17).
2. From the System clock menu, configure the following:
 Master clock (Master clock type):
 Adaptive (Clock is regenerated from an E1 bundle)
 Rx Clock (E1/T1 recovered Rx clock is used as the Tx clock)
 Master source (Source of the master clock, when the master clock type is
adaptive or Rx):
 Channel 1–4 (Master clock is provided via one of the TDM links. E1/T1
links can be locked to adaptive or loopback clock.)
 Fallback clock (Fallback clock type):
 Adaptive (Clock is regenerated from an E1 bundle)
 Rx Clock (E1/T1 recovered Rx clock is used as the Tx clock)
 Fallback source (Source of the master clock, when the fallback clock type
is adaptive or Rx):
 Channel 1–4 (Fallback clock is provided via one of the TDM links.
E1/T1 links can be locked to adaptive or loopback clock.)
