Alternate Mark Inversion (AMI)

Image
Alternate Mark Inversion (AMI) Extra information for course - not included in assessment. AMI (Alternate Mark Inversion) is a  synchronous  clock encoding technique that uses bipolar pulses to represent logical 1. The next logic 1 is represented by a pulse of the opposite polarity. Hence a sequence of logical 1s are represented by a sequence of pulses of alternating polarity. The alternating coding prevents the build-up of a d.c. voltage level down the cable. Example of AMI coding of NRZ data and the corresponding clock signal AMI (Alternate Mark Inversion) encoding was used extensively in first generation pulse code modulation networks, but suffers the drawback that a long run of 0's produces no transitions in the data stream (and therefore does not contain sufficient transitions to guarantee lock of a  DPLL ). Successful clock recovery therefore relies on the user not wishing to send long runs of 0's and this type of encoding is not therefore transparent to the sequence...

T1/E1 Basic Bit Error Rate Test

Image
T1/E1 Basic Bit Error Rate Test Overview The Bit Error Rate Test (BERT) application generates/detects unframed, framed, and fractional data that are defined in Pseudo Random Bit Sequence (PRBS). In addition to these, drop and insert capability is provided. A variety of standard data patterns are available for test purposes including static and user selected patterns. To open BER application, navigate to T1/E1 Analyzer > Intrusive Test > Bit Error Rate Test. Select the card on which BER test has to be performed. The screenshot given above displays the BER test application running on Card1: The functionality of the PRBS data stream is illustrated in the figure below: Framing Patterns selection for T1/E1 The framing patterns available in BER test are Unframed, Full-Framed, Fractional without Drop and Insert (D&I) and Fractional with Drop and Insert modes. These can be selected from the drop-down menu in the "Full-Fractional-Unframe" section. Unframed T1/E1:  Entire T1/...
