Connect and Register Handsets
Set Up Diagnostic Modem
Each MCU has an internal modem feature that allows Polycom
technicians to dial into the system for troubleshooting and
maintenance. The modem is enabled on Line 1 when no handset is
registered to Line 1. When enabled, the modem will auto-answer an
incoming call to that line.
This internal modem uses proprietary communication software.
You cannot use commercial software packages to access this
software. If you have a multiple MCU system, you only need to
enable one modem line, on Line 1 of MCU 1. Line 1 positions on
the other MCUs can be used for handsets.
To set up the diagnostic modem:
1. Connect an analog Direct Inward Dial (DID) line to Analog
Interface MCUs (SCA-5XX) or a digital DID line to Digital
Interface MCUs.
2. Move the mode switch to the REGISTER position. The LED for Line
1 should be off, indicating that no handset is registered to Line 1.
If the LED is on then a handset is registered to the line. Refer to
Chapter 6, section Unregister Handsets.
3. Dial the number associated with the DID line. After one or two
rings, you should hear the high-pitched modem answer tone.
