DTMF-A Unit

The DTMF-A provides an additional four DTMF receivers that may be used for detecting the
DTMF signal from the single line telephone port or central office line.
Installing the DTMF-A
1. Using a grounding strap, unpack the DTMF-A from its anti-static conductive bag in the
packing box.
2. Locate the CN13 and CN14 connectors (outlined) on the MPB.
3. Locate the CONN5 and CONN6 connectors on the DTMF-A.
4. Position the DTMF-A so CONN5 and CONN6 match CN13 and CN14 on the MPB.
5. Push the DTMF-A onto its connector making sure it is properly seated.
This completes the DTMF-A installation.
When using an analog voice mail system, the single on-board DTMF receiver is not
adequate to supply dial tone to single line devices and handle the demands placed
on it by voice mail. Therefore a DTMF-A must be installed.
