Installing Telephones and Adjuncts

Credit Card Verification Terminals

Connect the credit card verification terminal to one of the following, as described earlier in this section:

■012 module

■MLX telephone with an MFM

When connected through an MFM port, the transaction terminal places and receives calls independently of the MLX telephone.

Using a GPA is not recommended; the credit card verification terminal cannot dial out through the GPA.

Dial Dictations

Connect the dial dictation device to one of the following, as described earlier in this section:

■012 module

■MLX telephone with an MFM

■GPA and analog multiline telephone

Dial dictation can also be connected by using a commercially available “trunk adapter” or UPAM with a loop-start central office trunk jack and an external power supply unit.

NOTE:

Dial dictation equipment requiring contact closure cannot be connected via the MFM. Such equipment can be connected via the UPAM, as it provides the required contact closure.
