256 Attendant Break-In with Secrecy
In an MCDN ISDN environment, BKIS is an enhancement of Network
Attendant Service (NAS) Break-In (BKI). Please refer to ISDN Primary Rate
Interface: Features (553-3001-369) for more information regarding Network
Attendant Service Break-In.
Operating parameters
The same feature requirements apply as for the Break-In feature.
Within an ISDN environment
• All conditions for NAS Break-In must be met.
• In order for this feature to operate correctly over the network, all nodes
connected to the attendant must have Break-In software equipped.
In all cases, when displays are equipped, the information displayed is
consistent with current operation (that is, when connected to only one party,
the display shows the number and name, if equipped and configured, of that
party, and when connected to more than one party, the display is blank).
Feature interactions
Other than the interactions described below, the feature interactions are the
same as for the Break-In and NAS Break-In features.
Break-In to Enquiry Calls
Break-In with Secrecy interacts with Break-In to Enquiry Calls (BIEC) when
the desired party has gone on-hook leaving an undesired party off-hook and
excluded. BIEC has enhanced the existing BKI feature by giving overflow
tone to the undesired party if it is a 500 type telephone (irrespective of
whether the undesired party was involved in an enquiry call or not). BKIS
does not change this operation for non-BKIS calls.
BKIS has a choice of options to be given to the undesired party if the desired
party goes on-hook while the undesired party is excluded. These are taken
from the AOCS options in the Customer Data Block. These options are not
given to the undesired party if the undesired party has a call on hold. This
only applies to analog (500/2500 type) telephones. The BIEC treatment of
giving overflow tone is done instead so that the undesired party can be
reconnected to the held party.
Therefore, it is possible for analog (500/2500 type) telephones and trunks to
get different treatment depending on the circumstances.
The following is a list of treatments for different circumstances:
• Existing BKI BIEC disconnects undesired parties when the desired
party goes on-hook, except for analog (500/2500 type) telephones
where overflow is given. Therefore proprietary telephones and trunks
are disconnected.
