6. Connect and Register Wireless
Telephones
6.1 Set Up Diagnostic Modem
Each MCU has an internal modem feature that allows SpectraLink technicians to dial into
the system for troubleshooting and maintenance. The modem is enabled on Line 1 when
no Wireless Telephone is registered to Line 1. When enabled, the modem will
autoanswer 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 Wireless
Telephones.
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 Wireless Telephone is registered to Line 1. If the LED is
on then a Wireless Telephone is registered to the line. Refer to 6.3 Unregister
Wireless Telephones.
3. Dial the number associated with the DID line. After one or two rings, you should
hear high-pitched modem answer tone.
6.2 Register Wireless Telephones
Before a Wireless Telephone can be used it must be registered to a line on one of the
MCUs. While Wireless Telephones are being registered, the system will continue normal
operation.
Use the Wireless Telephone Planning Worksheet filled out by the system administrator to
be sure you are correctly assigning each Wireless Telephone to its port and extension
number.
All lines are unregistered when shipped from the factory. However, if you are replacing
a failed MCU you may not need to register the Wireless Telephones. Refer to 8. System
Administration for details.
! !
Line 1 MCU 1 should be skipped to allow for remote access through the
diagnostic modem.
Each MCU supports eight simultaneous conversations. To optimize
performance and reduce the possibility of call blocking, distribute the
Wireless Telephones evenly across all MCUs.
