Cascading Two Modules
The MG-IP units supports "external clock in" and "external clock out" via its dedicated mini-BNC
connector. Therefore, it can be configured as a TDM clock source (External Clock In). It may be used
as the TDM Tx clock for all connected TDM circuits. However, it may also be configured to export the
unit’s clock (Clock Out). This could be used to cascade two units in a system (see Figure 16) when, for
example, line timings are used.

Output Clock Options
The external clock connnector may be configured to output theMG-IP’s clock. For example, this may
be used when cascading two units.
The exported clock depends on the mode of operation as follows:
