9.12.2.1
The DS26518 transmitters can be selected individually to meet the pulse templates for E1 and T1/J1 modes. The
T1/J1 pulse template is shown in
shape can be configured for each LIU on an individual basis. The LIU transmit impedance selection registers can
be used to select an internal transmit terminating impedance of 100Ω for T1, 110Ω for J1 mode, 75Ω or 120Ω for
E1 mode or no internal termination for E1 or T1 mode. The transmit pulse shape and terminating impedance is
selected by
measured for compliance at the appropriate network interface (NI). For T1 long haul and E1, the pulse shape is
measured at the far end. For T1 short haul, the pulse shape is measured at the near end.
