Tenant Service; Tie Lines - Toshiba Strata DK14 General Description Manual

Features
System Features
With DK424, Release 3.2 and above, standard telephones and/or VM devices can establish tandem
analog CO line connections and then release them without disconnecting the tandem connection.
After releasing from tandem call, reconnecting to the call can be accomplished by dialing an
access code. This feature does not work if one or both of the CO lines are digital.
Tandem CO line volume level depends on the volume loss level of the Telephone Network CO
lines (see "Amplified Conference Interface" on Page

Tenant Service

Businesses in the same office building can share a system.
DK14 and DK40i each support up to two tenants
DK424 supports up to two tenants with RCTUA; all other processors support up to four
tenants
Tenants can have separate LCR and Toll Restriction plans, Page Groups/Zones, Night Transfer
ringing assignments, and flexible door phone and CO line ringing assignments.

Tie Lines

Tie lines can link the Strata DK40i or DK424 to other Strata DK systems or PBXs that support Tie
lines. Incoming Tie line calls can be routed to ring a number of destinations within the Strata DK
(see Table 29 on Page
Analog Tie lines are interfaced via the REMU PCB, each of which provides four circuits. The
interface options of Tie lines are: E & M Type I or Type II signaling, optional 2- or 4-wire
transmission, Wink or Immediate start. Digital Tie lines, available with DK424, are provided by
the RDTU2 and RPTU PCBs.
Tie lines do not reduce station capacity in DK424 Systems, Release 4.0. In DK40i, each Tie line
reduces the station capacity by one.
CO lines transferred from Strata DK to another system over Tie lines will recall back to the
originating Strata DK if the transferred call is not answered within a specified time (recall time is
flexible for each station). The recalling station number may display on the LCD of the telephone
being recalled.
An optional DTMF tone receiver PCB is required for Tie line operation:
DK14 does not support Tie lines
DK40i requires the K5RCU tone receiver
DK424 requires the RRCS tone receiver
Toll Restriction
Stations can be individually restricted from making toll calls. Separate restriction levels can be
defined, each allowing or denying specific area and office codes, long distance information calls,
international calls, and/or operator-assisted calls.
Each station is assigned any one of the available restriction levels or no restriction. Individual lines
can be defined as unrestricted. Restriction levels can also be assigned to verified account codes,
which require a user to enter an account code before dialing long distance.
