Notes to Table 39
1 A satellite tie trunk connects a satellite or tributary PBX to a main PBX.
A tributary PBX does not have its own directory number for incoming
calls.
2 The toll office designation is for a trunk to an office in the public
switched network with a higher rank than the local office (class 5).
3 The 1.5Mb PRI and DTI have digital pads which are controlled by
Meridian 1 software to provide the insertion loss given above. The 2Mb
PRI and DTI have programmable digital pads. The default value for these
pads gives the insertion loss in Table 39. The pad values can be printed
and changed in LD 73.
