3.3.15 TMGL4 (for U.S. Only)

Introduction

A central office trunk module (TMGL4) connects up to four analog ground-start or loop-start trunks to the OfficeCom and OfficePoint.

Use Hicom Assistant E to select ground start or loop start. Ground start is the default.

 
Caution 
You must disconnect the power and remove the slip-on connectors from the TMGL4 Module before removing it from the system.  
Do not connect the slip-on connectors to the TMGL4 Module until the board is seated in its slot and the system power is on. 
Failure to follow these instructions may severely damage the system.
