    E1 recovered receive clock (main E1 link or sub E1 link), from the user data ports, or from the internal oscillator. The ETU01C provide IDLE CODE mode, you can set any time slot and insert the idle code with ‘00'-‘FF', and the default code is ‘7F'.

  • Page 8: Typical System Applications

    PABX Figure 1-1: Example; Typical Application In a typical application (Figure 1-1), the ETU01C is used to connect the synchronous data channels of two routers and the local and remote LANs over an E1 line. The fractional E1 data service is based on the assumption that the combined user data rate of all channel modules plus Sub-Link is equal to or is a fraction of the full available E1 bandwidth, in multiples of 64K.
  • Page 9 Chapter 1 Introduction E1 transmissions utilize two main types of framing: Frame Alignment Signal (FAS) and Multi-Frame Alignment Signal (MFAS). Framing is necessary in order for equipment receiving the E1 signal to be able to identify and extract the individual channels. PCM-30 (CAS) transmission systems use MFAS framing along with FAS framing.

  • Page 10: Etu01C Capabilities

    The ETU01C E1 link receive path always operates on the receive clock. The ETU01C recovers the receive clock from the received E1 link data signal. The source of the ETU01C E1 link transmit clock can be selected by the user.
  • Page 11 The ETU01C E1 link transmit clock is derived from the internal clock oscillator. This timing mode is necessary in point-to-point applications over leased line. In this case, one ETU01C must use the internal oscillator, and the others must operate from the recovered clock.
