Discuss these factors with the System Administrator to ensure that
each user's requirements are considered before the method of
assigning a host switch extension number to the portable is
determined. The System Administrator ensures that the lines to the
host switch are wired and that the host switch is programmed
according to the method selected.
A portable is independent when the user is assigned a portable only.
The host switch directory number is assigned to the portable.
A portable that is assigned independently on the COMPANION 200
system is supported by an access line connecting the Controller to
the host switch. The access line is programmed at the host switch as
though it supports a standard analog telephone.
• Independent assignment can be used with any host switch.
• The portable can be given access to any host switch features
available to a standard analog telephone.
• A call in progress on the portable can be continued on any other
telephone by using Call Transfer, or any other similar host switch
feature. The call is interrupted briefly while the feature is
performed.
• Privacy of telephone conversations is ensured when independent
assignment of a host switch directory number is used. Since the
directory number is not shared, access to a conversation that is in
progress on the portable cannot be gained through any other
telephone.
A portable and a wired telephone are assigned in parallel when the
user is assigned both, and each has its own host switch directory
