NOTE: Optional tests are initiated from command mode. All tones sent from STC are TLP unless stated otherwise.

TLP Transponder Mode (804) Hz Activated)

1)

While in command mode, send 804 Hz.

2)

INTELIPORT applies quiet termination over the XMT IN port.

3)

STC performs noise measurements at the RCV OUT port.

4)

STC sends any tone from 300 Hz to 3200 Hz (except 2700 Hz), in 100 Hz increments, at TLP.

5)

INTELIPORT  returns similar tone (at a slight offĆset) for same duration tone is received, at +5 dBm (TLP or at the current XMT OUT

level established.

6)

Repeat Steps 4 and 5 as required.

7)

Upon completion and no other tone is sent by STC, INTELIPORT reapplies quiet termination and reĆsets 20Ćmin. timer.

8)

Send 2713 Hz for 0.9 seconds. INTELIPORT returns to command mode. Remove 2713 Hz.

9)

ReĆsend 2713 Hz for 0.9 seconds. INTELIPORT returns to idle.

DLP Transponder Mode (1304 Hz Activated)

1)

While in command mode, send 1304 Hz.

2)

INTELIPORT applies quiet termination at the XMT IN port.

3)

STC performs noise measurements at the XMT OUT port.

4)

STC sends any tone from 300 Hz to 3200 Hz (except 2700 Hz), in 100 Hz increments, at DLP.

5)

INTELIPORT returns similar tone for same duration tone is received, at Ć8 dBm (DLP) or at the current XMT OUT Level established.

6)

Repeat Steps 4 and 5 as required.

7)

Upon completion and no other tone is sent, INTELIPORT reapplies quiet termination and reĆsets 20ĆMin. timer.

8)

Send 2713 Hz for 0.9 seconds. INTELIPORT returns to command mode. Remove 2713 Hz.

9)
