9.1 Receive Test Procedure
Step Action
1. Connect oscillator set for 1khz at the RCV TLP, obtained in the receive alignment procedure, step 3, to
the RCV LINE jack.
2. Connect AC voltmeter terminated with 600 ohms to the RCV STA jack.
3. Verify the proper station equipment level as read on the AC voltmeter.
4. Adjust the oscillator for 2600Hz output. If equalizer is in, reduce 2600Hz oscillator level by the amount
of equalization.
5. Verify that the AC voltmeter reads –45dBm0 or less.
6. Remove plugs from the RCV STA and RCV LINE jacks.
9.2 Transmit Test Procedure
Step Action
1. Request the distant end to transmit 2600Hz idle tone.
2. Place –48VDC on the M lead (if CFM is conditioned for signaling mode) or a ground on the E lead (if
CFM is conditioned for trunk mode).
3. Connect the oscillator set for 1kHz at the XMT STA TLP, to the XMT STA jack.
4. Connect the AC voltmeter terminated with 600 ohms to the XMT LINE jack.
5. Verify the proper transmit line level as read on the AC voltmeter.
6. Disconnect oscillator from the XMT STA jack, and remove busy from the E or M lead.
7. Verify that the AC voltmeter reads –8dBm0 for approximately 400 milliseconds after E or M lead busy is
removed and then drop to a low level tone of –20dBm0.
8. Remove all test cords and place the circuit is service.
