d. Connect the RJ-11 6-pin connector of the Alignment Tool Headset to the RJ-11 utility
port of the SM.
Alternatively, instead of using the Alignment Tool Headset, use an earpiece or small battery-
powered speaker connected to Pin 5 (alignment tone output) and Pin 6 (ground) of an RJ-11
connector.
e. Listen to the alignment tone for
◦ pitch, which indicates greater signal power (RSSI/dBm) by higher pitch.
◦ volume, which indicates better signal quality (lower jitter) by higher volume.

Installing a PMP 400 Series SM
Installing a PMP 400 Series SM consists of two procedures:
• Physically installing the SM on a residence or other location and performing a course alignment using
the alignment tone.
• Verifying the AP to SM link and finalizing alignment using review of power level, link tests, and
review of registration and session counts (Procedure 24 on Page 404).
To install a PMP 400 Series (OFDM) SM, perform the following steps.
