Chapter 1 Introduction IPmux-1/1E Installation and Operation Manual
1-14 Functional Description
The IPmux-1E FXS operation modes allow IPmux to work opposite E1, T1-D4, or
T1-ESF. Two parameters are set internally when choosing one of the options:
A-Law/µ-Law
A-Law when E1 mode is selected
µ-Law is used in PCM CODEC when T1 (D4 or ESF) is selected.
E1, T1-D4, and T1-ESF with CAS are structured differently in the TDM IP
interworking function. A different structure must be used when working
opposite each one.

The TS assignment in a Bundle for IPmux-1E with BRI (when working opposite
IPmux with E1/T1 or Megaplex) is assigned as follows:

Figure 1-11. TS Assignment in a Bundle for IPmux-1E/BRI
As shown in Figure 1-11, the 4 BRI channels consume 12 timeslots in the Bundle.
The E1/T1 IPmux should work in framed mode (no CAS).
The three TS groups in the bundle are assigned according to BRI channel numbers;
the first group is assigned to the lowest BRI channel that is enabled, etc.
FXS
The TS assignment in a Bundle for IPmux-1E with FXS is straightforward. Each
timeslot in a Bundle is assigned to a specific FXS channel. Time slots in the bundle
are assigned according to FXS channel numbers; the first timeslot is assigned to the
lowest FXS channel that is configured, etc. As shown in Figure 1-11, the 4 FXS
channels consume 4 timeslots in the Bundle.
The E1/T1 IPmux that works opposite the FXS channels should work in Framed
with CAS mode.
Testing
Diagnostic capabilities include E1/T1 or BRI S local and remote loopback tests for
rapid localization of faults. The E1/T1 or BRI S channel can be looped locally,
toward the line, or toward the remote end (see Chapter 4 for more information).
Remote Loopback and Tone Injection are available for the FXS port.
