11/01/00 19:23 HCD-E1 Command Set Description 4-19
HCD-E1 displays the BERT parameters data form:
PATTERN ERROR_INJECTION_RATE RX_INBAND
2E3-1 NO ERR DISABLE
The functions of the fields are as follows:
PATTERN Selects the test pattern. The available selections are the QRSS test pattern, and the following
pseudo-random sequences: 2E3-1, 2E4-1, 2E5-1, 2E6-1, 2E7-1, 511, 2E10-1, 2047, 2E15-1,
2E17-1, 2E18-1, 2E20-1, 2E21-1, 2E22-1, 2E23-1, 2E25-1, 2E28-1, 2E29-1, 2E31-1, 2E32-1.
ERROR_
INJECTION_
RATE
Enables the injection of a calibrated rate of errors in the transmitted test pattern.
The available selections are: 10E-1, 10E-2, 10E-3, 10E-4, 10E-5, 10E-6, 10E-7, NO ERR, or
SINGLE.
• Select NO ERR to disable the injection of errors
• Select SINGLE to enable the injection of single errors
• Select 10E-1 to enable the injection of errors at a rate of 10E-1 (one error in every 10
test pattern bits), and same with 10E-2, 10E-3, 10E-4, 10E-5, 10E-6, up to 10E-7 (one
error in every 10 million test pattern bits).
See DSP BERT CH command below for the error injection procedure.
RX_INBAND Controls the receipt of the in-band loopback activation pattern. The available selections are
ENABLE and DISABLE.
• Select ENABLE to enable initiation of the in-band loopback upon receipt of the
activation pattern.
• Select DISABLE to disable the in-band loopback activation pattern receipt.
2. Move the cursor to the desired field using the spacebar, and change, if
necessary, using the F or B keys. After making the desired selections,

the HCD-E1 prompt.
DEF CH
Purpose
Define the data channel parameters of HCD-E1.
Syntax
DEF CH X
Use
1. Define the channel parameters as follows:
•
To define channel 1 parameters, type:
DEF CH 1<CR>
•
To define channel 2 parameters, type:
DEF CH 2<CR>
HCD-E1 displays the first line of the channel parameters data form. A
typical form is shown below:
