Misoperation Handling
Misoperation Handling defines how calls are handled when a misoperation 
occurs. A misoperation can occur either:
nWhen a user with a call on hold goes on-hook before an operation 
completes. In some cases, going on-hook completes the operation, as in 
call transfer.
nWhen the system enters Night Service while attendant consoles have calls 
on hold.

1430 Misoperation Handling 
20
You can alter standard Misoperation Handling to ensure that callers are not left on 
hold indefinitely with no way to reach someone for assistance or that callers are 
not dropped by the system. See Misoperation Alerting and Intercept Treatment on 
Failed Trunk Transfers on the Feature-Related System Parameters screen for more 
information. 
Contact a Lucent representative for instructions on administering Misoperation 
Handling for use in France. 
Detailed description
Misoperation handling varies considerably, depending on how it is administered 
and what conditions are in effect when a call is placed on hold.
Standard operation
Standard misoperation handling is in effect when you set the Intercept Treatment 
on Failed Trunk Transfers field to 
y and set the Misoperation Alerting field to n.
The type of telephone that is in use when the misoperation occurs (analog 
single-line or digital multiappearance) affects standard misoperation handling.
The following scenario describes a typical misoperation on an analog terminal.
1. While connected to an incoming external call, an analog-terminal user 
flashes with the intent of transferring the call to another terminal.
2. The user hears dial tone, dials an invalid extension, and hangs up.
3. A misoperation occurs. The analog-terminal user receives priority ringback 
indefinitely.
The following scenario describes a typical misoperation on a digital terminal.
1. While connected to an incoming external call, a digital-terminal user with a 
call on hold goes on-hook during another feature operation before 
completing the operation.
2. The user hears dial tone, dials an invalid extension, and hangs up.
3. A misoperation occurs unless going on-hook completes the operation (for 
example, call transfer). The held call remains on hold indefinitely with a 
flashing call-appearance lamp.

1431 Misoperation Handling 
20
Enhanced operation
Once you enable Misoperation Alerting, calls are handled depending upon the 
type of call placed on hold and the type of telephone (digital multiappearance, 
analog single-line, or attendant console) in use when the misoperation occurs. The 
following list describes the 3 call types that determine misoperation handling.
nCall Type 1 — An outgoing public-network call is classified as Type 1 
when answer supervision is received or when the trunk group’s Answer 
Supervision Timer expires, even if the trunk is still ringing. An incoming 
call is classified as Type 1 when it is answered.
nCall Type 2 — An incoming external-public-network call is classified as 
Type 2 before it is answered. A misoperation cannot occur with a Type 2 
call because an unanswered incoming call cannot be placed on hold 
without first being answered.
nCall Type 3 — All internal calls, conference calls, and tie-trunk calls are 
classified as Type 3.
Analog terminal misoperation
The following 2 scenarios describe typical misoperations on an analog terminal.
Scenario 1. 
1. While connected to an incoming external call (Type 1), an analog-terminal 
user flashes to transfer the call to another terminal.
2. The user hears dial tone, dials an invalid extension, then hears intercept 
tone.
3. When the user hangs up, the call re-alerts the user for 15 seconds and 
eventually routes to the attendant.
Scenario 2. 
1. While connected to an incoming external call (Type 1), an analog station 
user flashes to place the call on hold while calling another extension.
2. The user hears dial tone and dials the CAS Remote Hold/Answer 
Hold/unhold access code.
3. The user dials an extension and talks with the user at the extension and 
hangs up.
4. A misoperation occurs because the first call is still left on hold.
5. The terminal is alerted for 15 seconds and the call routes to an attendant.
6. If the first call is not answered before the timer expires, the call drops.

1432 Misoperation Handling 
20
Digital terminal misoperation
The following scenario describes a typical misoperation on a digital terminal.
1. While connected to an incoming external call (Type 1), a digital-terminal 
user places the call on hold to transfer the call to another terminal.
2. The user hears dial tone, dials an invalid extension, and hangs up.
3. A misoperation occurs. The call on hold rings the terminal again (not 
priority ringing) for the number of rings administered for call coverage.
4.The call then routes to the terminal’s coverage path, which directs the call 
to an announcement and/or disconnects.
Attendant console misoperation
A misoperation occurs on an attendant console with calls on hold only when the 
system enters Night Service.
1. The system enters Night Service with calls on hold at an attendant console.
2. All calls on hold re-alert (as if the Held-Call Timed-Reminder had 
expired).
3. When the calls start re-alerting, a timer starts. The timer is set to the value 
assigned in the Alerting (sec) field on the Console-Parameters form.
4. If the attendant does not answer the calls before the timer expires, calls 
route to the system Night Service destination. Calls that are not answered at 
the night service destination before the night-service-disconnect timer 
expires are dropped.
Interactions
nAttendant Lockout
Attendant Lockout is temporarily disabled on calls that re-alert the 
attendant console following a misoperation. This allows an attendant to 
answer the calls.
nBridged Appearances
Misoperation Alerting calls do not re-alert on bridged call appearances.
nVoice Response Integration
Do not use Misoperations Handling with this feature if you are using 
analog boards with Conversant.

1433 Modem Pooling 
20
Modem Pooling
(Not available with Offer B) Modem Pooling allows switched connections 
between digital-data endpoints (data modules) and analog-data endpoints via pods 
of acoustic-coupled modems. The analog-data endpoint is either a trunk or a line 
circuit.
Detailed description 
Data transmission between a digital data endpoint and an analog endpoint requires 
conversion via a modem, because the Digital Communications Protocol (DCP) 
format used by the data module is not compatible with the modulated signals of an 
analog modem. A modem translates DCP format into modulated signals and vice 
versa.
Modem Pooling feature provides pools of integrated-conversion modems and 
combined-conversion modems.
Integrated-conversion modem pools have functionality integrated on the Pooled 
Modem circuit pack, providing two modems. Each one emulates a time-division 
multiplexing (TDM) cabled to a 212 modem. Integrated are modem pools not 
available in countries that use A-law companding.
Combined-conversion modem pools are TDMs cabled to any TDM-compatible 
modem. Combined-conversion modem pools can be used with all systems.
When the system needs a modem, it queries the digital-data module associated 
with the call to determine if the module’s options are compatible with those 
supported by the modem pools. If the options are not compatible, the originating 
user receives intercept treatment. If the options are compatible, the system obtains 
a modem from the appropriate pool. If a modem is not available, the user receives 
reorder treatment.
The system can detect the needs for a modem. Data calls from an analog-data 
endpoint require that the user indicate the need for a modem, because the system 
considers such calls to be voice calls. Users indicate this need by dialing the 
data-origination access code before dialing the digital-data endpoint.
The system provides a Hold Time parameter to specify the maximum time any 
modem can be held but not used (while a data call is in queue).
The integrated-conversion modems support the following options:
nReceiver responds to remote loop
nLoss of carrier disconnect

nSend space disconnect
nReceive space disconnect
nCF-CB common
nSpeed, duplex, and synch (administered)
Combined-conversion modems support the following:
nIBM bisynchronous protocols typically used in 3270 and 2780/3780 
applications. Both require 2400 or 4800 bps, half-duplex, synchronous 
transmission.
nInteractive IBM-TSO applications using 1200 bps, half-duplex, 
asynchronous transmissions
nDATAPHONE II switched-network modems supporting asynchronous and 
synchronous communications, and autobaud at 300, 1200, or 2400 bps
nThe DEFINITY ECS operating at up to 19.2 kbps
nDifferent pools with different data-transmission characteristics
Considerations
nOn data calls between a data module and an analog-data endpoint, 
Return-to-Voice releases the modem and returns it to the pool. The phone 
user connects to the analog-data endpoint.
nFor traffic purposes, the system accumulates data on modem-pooling calls 
separate from voice calls. Measurements on the pools also accumulate.
nWhen a phone user places a data call to a digital-data endpoint, does not 
transfer the call to another digital-data endpoint, and uses a modem or 
acoustically-coupled modem, the user dials the data-origination access 
code before dialing the distant endpoint.
nModem Pooling is not restricted. Queuing for modems is not provided, 
although calls queued on a hunt group retain reserved modems. 
nAvoid mixing modems from different vendors within a combined pool 
because such modems may differ in transmission characteristics. 
nWhen you administer data-transmission characteristics (speed, duplex, and 
synchronization mode), they must be identical to the TDM and optional 
modem selections made by the customer.
nEach data call that uses Modem Pooling uses four time slots (not just two). 
As a result, heavy usage of Modem Pooling could affect TDM 
bus-blocking characteristics.

nTandem switches do not insert a pooled modem. The originating switch 
inserts a pooled modem.
Interactions
nCall Detail Recording
Data call CDR records the use of modem pools on trunk calls.
nData Call Setup
Data calls to or from a TDM cannot use Modem Pooling.
nData Privacy and Data Restriction
The insertion of a modem pool does not turn off Data Privacy or Data 
Restriction.
nData-Only Off-Premises Extensions
Calls to or from a Data-Only Off-Premises Extension cannot use Modem 
Pooling, when this type of digital-data endpoint uses a TDM.
nDigital-multiplexed Interface Trunks
If you place a data call from a local analog-data endpoint to a DMI trunk, 
you must dial the data-origination access code to obtain a modem. Data 
calls on DMI trunks to local analog-data endpoints automatically obtain 
modems.
nDS1 Tie Trunk Service
Connect modems used for Modem Pooling to AVD DS1 tie trunks via Data 
Terminal Dialing or by dialing the feature-access code for data origination.

1436 Multiappearance Preselection and Preference 
20
Multiappearance Preselection and 
Preference
Multiappearance Preselection and Preference selects the call appearances you use 
to connect to when you lift the handset.
Multiappearance Preselection and Preference provides multiappearance telephone 
users with the following options for placing or answering calls on selected call 
appearances.
nRinging Appearance Preference
When a user lifts the handset to answer a call, the system automatically 
connects them to the ringing call appearance. If there is more than one call, 
the user automatically connects to the oldest (first-in) ringing call 
appearance. The in-use (red) lamp tracks the ringing appearance and the 
answered appearance.
nIdle Appearance Preference
When a user lifts the handset to place a call, the system automatically 
connects them to an idle appearance even if an incoming call is ringing at 
another appearance. The in-use (red) lamp tracks an idle appearance when 
the user lifts the handset.
nLast Appearance Preference
When a user lifts the handset, they connect to the call appearance or 
bridged appearance last used for a call, unless an audibly ringing call on a 
different appearance caused the line selection to move. If the line selection 
moves, a call may be originated, answered, or unheld, depending on the 
state of that appearance.
nPreselection
Before lifting the handset to place or answer a call, the user can press a call 
appearance button or a feature button to select an appearance when the 
in-use lamp is dark. Preselection reenters a held call or activates a feature 
or the speakerphone if the telephone is so equipped.
Preselection overrides both Preference options. If the user does not lift the 
handset within 5 seconds after using Preselection, the selected appearance 
returns to idle.
You can assign a preselection feature button. For example, if a user presses 
an Abbreviated Dialing button, a call appearance is automatically selected. 
If the user lifts the handset within 5 seconds, the system automatically 
places the call.
