Installation and Operation

Link WTS – Link 150 M3 MCU

11.2 Change Companding

The factory setting on the

Link 150 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 Wireless Telephones 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 8.5

Replace an MCU

for instructions.

To change the default from Mu- to A-law on the

Link 150 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

NORM

position.
