SpectraLink 6100 MCU: Installation and Operation: SpectraLink 6000 System

2. Power the system on. STATUS LEDs 5 and 1 should be lit,

indicating frequency selection mode. One of the LINE LEDs from 1

to 7 will be indicating the current frequency selected for the MCU.

3. Use the STEP button to select the desired new sequence.

4. Press the DEL/ENTER button. The LED indicates the new frequency

that has been selected.

5. Return the mode switch to the NORMAL position.

6. Repeat steps 1 through 5 for each MCU of a multi-unit

installation.

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.
