TRS/Barring checks only the dialled telephone number excluding the Host PBX Access code whenaccessing the telephone company through the host PBX. (® 1.9.1 Toll Restriction (TRS)/Call Barring(Barring))• ARSA pause is not automatically inserted between the user-dialled access code and the subsequent digitswhen the ARS mode is enabled. (1.10.1 Automatic Route Selection (ARS))• SMDRThe dialled number including the Host PBX Access code will be recorded on SMDR only if the modifiednumber setting is selected in the ARS setting for SMDR.• When a Host PBX Access code is assigned to a trunk group, calls to extensions of the host PBX are notrecorded on SMDR.• A Host PBX Access Code can be used to record only long distance calls on SMDR when a trunk port isconnected directly to the telephone company (not a host PBX). This is allowed when the long distancecode (e.g., "0") is assigned as the Host PBX Access code. All local calls (e.g., calls that do not require a"0" to be dialled first) are treated as extensions of the telephone company and do not get recorded onSMDR, because in this case this PBX recognises the telephone company as the host PBX.Therefore, only long distance calls are recorded on SMDR.PT Programming Manual References[471] Host PBX Access CodeFeature Guide References1.26.1 Station Message Detail Recording (SMDR)3.1 Capacity of System Resources86 Feature Guide1.5.4 Trunk Call Features
