Anrtisu Site Master S331D - E1 Tester Mode Menus (Option 50)

E1 Tester Mode Menus (Option 50)
In E1 Tester mode (Option 50, S331D only), the FREQ/DIST and AMPLITUDE hard
keys are not used. Pressing the MEAS/DISP key in E1 Tester mode causes the soft keys,
below, to be displayed:
q
BERT — Activates menus that are used Bit Error Rate Testing (BERT).
q
Setup BERT — Activates menus that are used to set BERT testing op
-
tions.
q
Framing Mode — Selects the framing mode to be used.
q
Auto — Automatically detects the received framing mode.
q
PCM30 — Sets the E1 framing mode to PCM30.
q
PCM30 CRC — Sets the E1 framing mode to PCM30 with CRC.
q
PCM31 — Sets the E1 framing mode to PCM31.
q
PCM31 CRC — Sets the E1 framing mode to PCM31 with CRC.

q
Receive Input
q
Terminate — Terminates the circuit under test with either 75 or
120 ohms. Terminate mode is used to test out of service or newly
installed E1 lines when there is no traffic data.
q
Bridged — Bridged mode provides greater than 1 kW impedance to
test the in-service line by bridging the receiver input across E1
lines.
q Monitor +20 dB — Monitor mode adds 20 dB of gain, and is used
when the connection to the circuit under test is through a 20 dB
pad.
q
Back — Returns to the previous menu.
q
Pattern — Opens a list of available BERT patterns. Use the soft keys
or the Up/Down arrow key to highlight a pattern and press ENTER to
select.
q
Line Coding — Selects the line coding to be used.
q
HDB3 — High Density Bipolar. An E1 code in which bipolar vio
-
lations are inserted if the user data contains more than three con
-
secutive zeros.
q
AMI — Alternate Mark Inversion. A bipolar signal in which ones
are encoded as pulses with alternating polarity, and zeros are en
-
coded as zero amplitude.
q

q
Clock Source — Selects the clock source.
q
Internal — Uses the internal clock.
q
External — The clock is recovered from the receiver signal.
q
Back — Returns to the previous menu.
q
Setup Error Insert — Opens the error insert menu.
q
Bit — Configures the unit to insert bit errors.
q
BPV — Configures the unit to insert Bipolar Violations.
q
Framing Bits — Configures the unit to insert framing bit errors.
