Tie Lines
Strata DK General Description 6/00 91
Tie Lines
Tie lines can link the Strata DK40i or DK424i 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 34 on Page 68).
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 DK40i and DK424i, are
provided by the RDTU2 and RPTU PCBs.
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
♦ DK424i requires the BRCS 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.
Toll Restriction Override by System Speed Dial
System Speed Dial numbers can be programmed to override Toll Restriction. When employees
need to access a toll number that falls into a restricted area/office code for work purposes, an
employer can assign the particular toll number as a System Speed Dial number. After overriding
Toll Restriction with system Speed Dial, the caller can be blocked from or allowed to dial
additional digits. Dialing long distance provider access codes (10XXX and 101XXX) is not
allowed, except when entered via a System Speed Dial number or LCR.
Traveling Class of Service
The normal Toll Restriction class of a station can be temporarily changed to another class. Each of
the Toll Restriction classes can be assigned a four-digit code.
If one of these codes is entered at any station, the station assumes the class associated with the
code for the next dialed number. Then the station reverts back to its normal Toll Restriction class
for subsequent calls. Traveling Class codes can be added, deleted, or changed by users from
stations selected in programming.
Traveling Class codes will not appear on the SMDR reports. Verified account codes, which can
also change Toll Restriction Class of Service, do print out on SMDR reports.
