- Fractional E1: Configures the transmitter for fractional testing using N or M 64kbit/s timeslots. (Contiguous or non-Contiguous
timeslots).
In STS-1 mapping mode/Tributary set to E3, the Low Rate option are 34M or 2M Mux (E3//E1 Mux) or Fractional E1 Mux (E3//E1
Mux w/Nx64) where;
- 34 M: Configures the transmitter for full rate testing at 34Mbit/s
- 2 M Mux mode: Configures the transmitter for full rate testing at 34Mbit/s signal with E1 payloads (1 to 16 channels)
- Fractional E1 Mux mode : Configures the transmitter for full rate testing at 34Mbit/s signal with E1 payloads (1 to 16 channels)
for fractional testing using N or M 64kbit/s timeslots. (Contiguous or non-Contiguous timeslots).
FRAMING:
Depends on low rate selected;
In DS1 mode, the options are unframed, D4 (SF) and ANSI T1.107 (ESF)
In DS3 mode, the options are unframed, M13 and C-Parity
In E1 mode, the options are unframed, PCM31, PCM31C, PCM30, and PCM30C. Framing conforms to G.704 and G.706
recommendations and are briefly described below;
In E3 mode, the options are unframed, framed G.751.
7.4.5 Tx Setup > Pattern
Tapping the Tx Pattern box opens the Tx Pattern Setup screen.
PATTERN:
Use the pattern drop down box to select the test pattern which will be inserted into the transmitted signal. Pseudo
Random Bit Sequences (PRBS) defined by ITU-T 0.181 standards, fixed words and 24 bit user defined patterns are available.
INVERT:
Inversion of PRBS polarity is also available. Inversion of fixed words is not permitted.
7.5 SONET Receiver Setup
7.5.1 Rx Setup > Hierarchy
Tapping the Hierarchy setup box opens the Rx Hierarchy screen. The Hierarchy setup options for the Rx are the same as for the
Tx described previously.
