*Column D equals deviation from 0dBm (TLP)
**Column E equals Customer's RCV OUT level
Note: During this procedure, all tones from STC are sent at TLP.
1)
Send 2713 Hz for more than 30 seconds. After detecting 2713 Hz for more than two seconds, INTELIPORT returns a 1Ćsecond,
alternating tone of 1014 Hz/414 Hz (Unit I.D. tone) indicating the unit being accessed as Westell's INTELIPORT 1, Model
SDS5486LN.
2)
After detecting 2713 Hz for more than 30 seconds, INTELIPORT sends 1014 Hz at +5 dBm (TLP). Record level received in Column
B. Remove 2713 Hz. Command mode initiated. (NOTE: if XMT OUT level requires adjustment it is accomplished after completing
Steps 3 through 12. Procedures for adjusting XMT OUT level is given on page 15, under Optional Tests).
Remote Alignment Mode
3)
While in command mode, send 1004 Hz.
4)
INTELIPORT returns 2814 Hz
5)
Record level at 2814 Hz in Column B, then send 2804 Hz
6)
INTELIPORT returns 414 Hz.
7)
Record level at 414 Hz in Column B, then send 404 Hz
8)
INTELIPORT returns 1814 Hz for 120Ćseconds.
9)
Record level at 1814 Hz in Column B. STC has option of aligning the circuit to either 3 tones or 4 tones:
3ĆTone Alignment
Ignore 1814 Hz tone from INTELIPORT After 120 seconds*, 1814 Hz tone times out. INTELIPORT aligns to
3 tones, sends rampĆup or rampĆdown tone, then enters loopback. *NOTE: Send 1004 Hz within 120Ćsec.
time frame to bypass timer circuit..
4ĆTone Alignment
Send 1804 within 120Ćsecond time frame. INTELIPORT aligns to 4 tones, sends Ćup or rampĆdown tone,
then enters loopback.
Loopback
10) Send 404 Hz. Record level received from INTELIPORT in Column C.
11) Send 1004 Hz. Record level received from INTELIPORT in Column C.
12) Send 2804 Hz. Record level received from INTELIPORT in Column C.
13) (OPTIONAL) Send 1804 Hz. Record level received from INTELIPORT in Column C.
14) Send 2713 Hz for 0.9 seconds. INTELIPORT returns to command mode. Remove 2713 Hz.
15) ReĆsend 2713 Hz 0.9 seconds. INTELIPORT returns to idle. Remove 2713 Hz.
16) Perform calculations for Columns D and E as required.
