1.25.6 Virtual PSDescriptionAn extension number can be assigned for a portable station (PS) without registering the PS unit itself. This isknown as temporary registration. If a forward destination is then assigned for this PS, all calls to that extensionnumber will be forwarded to the assigned destination. Using this setting to forward calls to outside destinationsor destinations at another PBX allows those destinations to receive calls as if they were within the PBX. Inaddition, depending on system programming, the forward destination can use some of the features of the PBX.This can be especially useful for a cellular phone user, who can use his cellular phone as if it were his extensionwhen he is away from his desk.[Example]PBX-1TIE Line NetworkTIE LinePBX-2Outside CallerTelephone CompanyVirtual PS 2Virtual PS 1Dials "201"Extn. 201Fwd to outsidedestinationExtn. 202Fwd to destinationat other PBXThe following features can be accessed using this method:Feature Description & ReferenceOutside Destinations inIncoming Call DistributionGroupA virtual PS allows calls to an Incoming Call Distribution (ICD) Groupto be answered by outside destinations or extensions at another PBX.® 1.2.2.3 Outside Destinations in Incoming Call Distribution GroupNetwork ICD Group Using virtual PSs in an ICD Group, up to 4 other PBXs can be calledat the same time.® 1.30.6 Network ICD GroupPS Roaming by Network ICDGroupOne PS can be registered at up to 4 PBXs.
