Wire Test Mode
CAUTIONĆINTELIPORT places 1014Hz tone on the transmission pairs when TEST mode is activated. Be sure INTELIPORT
is not connected to an inĆservice circuit where this tone may cause interference.
Momentarily press the frontĆpanel TEST switch (less than five seconds) and release. Verify FAIL/TEST LED is flashing. ConĆ

When tones are verified, press TEST switch to end test mode. Test mode automatically times out one hour after initial acĆ

Serving Test Center's Procedures
Send 2713 Hz (>30 sec.*) at TLP to INTELIPORT's RCV IN port. Verify steady 1014 Hz at +5dBm (TLP) from INTELIPORT.

remove 2713 Hz. Command mode initiated.
Note: if 2713 Hz is present for two sec. but removed in less than 30 seconds, INTELIPORT sends a 1Ćsecond alternating
tone of 1014 Hz/414 Hz and enters loopback.

Remote (Manual) Alignment Mode
From command mode, verify/record level received at 1014 Hz, then send 1004 Hz to INTELIPORT.
Upon detecting 1004 Hz, INTELIPORT returns 2814 Hz.
Verify/record level received at 2814 Hz, then send 2804 Hz to INTELIPORT
Upon detecting 2804 Hz, INTELIPORT returns 414 Hz.
Verify/record level received at 414 Hz, then send 404 Hz to INTELIPORT.
Upon detecting 404 Hz, INTELIPORT returns 1814 Hz for 120 seconds.
Verify/record level received at 1814 Hz. At this point, STC has option of aligning to 3 tones or 4 tones.
3Ćtone alignment: Ignore 1814 Hz tone. After 120 seconds, 11814 Hz tone from INTELIPORT times out.
INTELIPORT aligns to 3 tones, returns a rampĆup or rampĆdown tone*, applies quiet termination for one second,
then enters loopback. NOTE: 120Ćsecond timer can be bypassed by sending 1004 Hz during the 120Ćsecond
time frame.
4Ćtone alignment: Send 1804 Hz in response to INTELIPORT'S 1814 Hz in response to INTELIPORT's 1814 Hz

within the 120 time frame. INTELIPORT aligns to 4 tones, returns a rampĆup or rampĆdown*, applies quiet
termination for one second, then enters loopback.
NOTE: Upon completion, if a level other than +5dBm (TLP) is required at the XMT OUT port the STC should access the
XMT OUT Level Adjust mode to set the desired output level.
Note: RampĆup tone (314 Hz to 3014 Hz) indicates alignment is within C5 conditioning. RampĆdown tone (3014 Hz to 314
Hz) indicates alignment is not within C5 conditioning.
AutoĆAlign Mode
Note: AutoĆalign is initiated by pressing the frontĆpanel TEST switch (more than five seconds) during the first five minutes
of initial powerĆup, or via command mode by sending 1804 Hz to INTELIPORT.
When activated, INTELIPORT sends 2913 Hz out of the RCV IN port to near end to put near end into command mode.
Near end, upon entering command mode, returns command mode tone to INTELIPORT. With both Stations set, tones are
automatically sent and received between both ends. Upon completion (approximately two to three minutes), INTELIPORT
returns to idle. Near end also returns to idle.
