Reply To: Switch Planning for GSM


Hi Jani,

LTG its a siemens terminology, for Line Trunk Group.

DIU OR DSL: Digital interface Unit : is the interface where the actual E1s are terminated

Four DIU are connected to One LTG card.Siemens switch has a maximum of 256 LTG. that means u can have 256*4=1024 number of E1s terminated in a single switch.

I hope i have cleared u r doubt.
