Figure 1-8. Frame Structures for E1/CEPT and T1 TDM Interfaces
For any station to receive and transmit on a TDM line, it is necessary for it to determine the
correct time slot boundary. The service provider or the PTT provides a 4-wire interface with
a continuous bit stream coming down the line. The T1 and E1 have information embedded
in the data stream that delineates frames. The bit pattern in position 193 in T1 over a period
of several frames establishes a synchronization pattern. A station may have the capability
to search for this pattern and thus find the correct time for frame synchronization. In a
similar way, time slots 0 and 16 are reserved not only for synchronization but also for
signaling in the E1 interface.
Depending on its capability, a node can either extract this synchronization information or
it can be supported by framer and time slot assigner devices.
