Configuring a TDM clock source

Introduction to TDM clock source
When digital voice E1 interfaces perform time-division multiplexing (TDM) timeslot interchange, it is
important for them to achieve clock synchronization to prevent frame slips and bit errors.
Depending on your configurations on E1 interfaces, the system adopts different clocking approaches.
When there is a voice co-processing module (VCPM) on the main board, the clock distribution
principle is as follows:
•
If the clock mode is set to line for all interfaces, the clock on the interface with the lowest
number is adopted. If the interface goes down, the clock on the interface with the next lowest
number is adopted.
•
If the clock mode is set to line primary for one interface, the clock on the interface is adopted.
In one system, you can do this on only one interface.
•
If the line keyword is specified for one interface and the internal keyword for all others, the
clock on the interface is adopted.
•
Generally, you cannot set the clock source for all interfaces in a system to internal. This is to
prevent frame slips and bit errors. You can do this, however, if the remote E1 interfaces adopt
the line clock source.
