A TMGL4 trunk module connects up to four analog ground-start or loop-start trunks to HiPath 3550 and HiPath 3350.
Ground start is the default.

You must disconnect the power and remove the slip-on connectors from the TMGL4 board before removing it from the system.  
Do not connect the slip-on connectors to the TMGL4 board until the board is seated in its slot and the system power is on.
