Change Companding
The factory setting on the SpectraLink 6100 MCU is compatible with
Mu-law companding (signal compression), which is the standard
used by most PBXs in North America. Systems outside North
America generally use A-law companding. If the PBX companding is
incompatible with the MCU’s, the handsets will have distorted or
hissing dial tone, and voice will be unintelligible.
Before you begin, if the system has more than one MCU, erase the
configurations from all MCUs except MCU 1. Refer to Chapter 8,
section Replace an MCU for instructions.
To change the default from Mu- to A-law on the SpectraLink 6100
MCU follow these steps.
1. Power the system off.
2. Slide the mode switch on the first MCU to the
ADMIN position.
3. Power the system on.
STATUS LEDs 2, 3, and 4 will be solid green.
4. Press the
STEP button once. STATUS LEDs 2 and 5 will be lit.
5. If the LED for
LINE 1 is lit, the system is set for Mu-law.
If the LED for
LINE 2 is lit, the system is set for A-law.
6. Press the
DEL/ENTER button to toggle between Mu-law and A-law.
7. When the correct
LINE LED is lit, return the mode switch to the
NORMAL position.
