Description
Centrex/PBX Compatibility allows the System to be connected behind centrex or PBX lines.
The System supports up to 6 access codes for dialling centrex or a PBX. These access codes allow the
System, System Message Detail Recording (SMDR) (Call Logging) output to exclude the number
dialled to reach a centrex or PBX line.
When connected behind a PBX or Centrex, Toll Restriction Service (TRS) (Call Barring) can be used
to restrict calls.
The System also supports transmission of a flash signal over the centrex or PBX link.
