3.3.13 TMAMF (for selected countries only)

Introduction

The TMAMF (Trunk Module Analog for Multifrequency Code Signaling) board contains eight trunks for analog direct inward dialing. The system supports MFC-R2 signaling (default setting), MFC-R2 with caller ID, tone dialing, and dial pulsing. It is not possible to use DTMF and MFC-R2 (with or without caller ID) simultaneously.

You can use this board in Hicom 150 E OfficePro only.

Notes on DSP Diagnosis

You can use the trace function built into the TMAMF module to diagnose malfunctions or obtain more precise error analysis. After you run the trace, the subminiature D connector provides information about MFC-R2 signaling. To activate the trace function, you must connect a PC with a terminal emulation program (such as Microsoft HyperTerminal).

Terminal Configuration:

Bits per second = 19,200
Data bits = 8
Stop bit = 1
Parity = none
Flow control = none
