Introduction

Attendant consoles are designed to assist in placing and extending calls into and out of a telephone switching system. The console is operated by an attendant who is the human interface between the system and the users.

The M2250 attendant console is a stand-alone, digital attendant console designed for telephone traffic control in the CS 1000 and Meridian 1. A Digital Line Card (DLC) connects the M2250 to the system.

The PC-based Console application software allows all functions supported by the M2250 to be performed on a computer workstation within a Windows 95®, Windows 98®, Windows 2000®, or Windows NT® operating system environment. The PC-based Console application operates with the PC Console Interface Unit (PCCIU). The PCCIU is typically installed under the attendant’s PC monitor, and provides connection to the Main Distribution Frame (MDF) and PC communications port. The PCCIU is configured as an M2250 attendant console in LD 12. Refer to Software Input/Output: Administration (553-3001-311) for configuration information

In the North America, Asia Pacific and CALA market regions, the PCCIU and the Attendant PC software are available as a bundled package. In the EMEA market region, the PCCIU is available on its own or with a separate PC software application called SMILE.

Connections

The line cord connects to the rear of the M2250 attendant console through a 25-pin subminiature D-type connector. The jack connector is attached to the line cord for user safety and equipment protection (pins are not exposed). Having the plug connector mounted in the console also prevents interchanges between the line cord and the serial data port connectors (the serial data port in the console has a jack connector).

Identical two-prong G3 type connectors are provided on each side of the console body to permit handset or headset connection at either side of the console. The M2250 attendant console is compatible with both carbon and electret handsets or headsets. The electret handset plug is orientation-dependent and is labeled accordingly.

The attendant console is connected to the system through two digital ports – one port for Call Service processing and one for Call Destination processing – with three additional ports for powering, for a total of five ports. The PCCIU interface used for the PC-based Console software application requires only three ports in total.

The attendant console requires a Digital Line Card (DLC) or an Integrated Services Digital Line Card (ISDLC) NT8D02 or later.

Local console controls

Visual contrast on the display panel can be adjusted using the Contrast option on the Options menu.

From the Options menu, four-line mode can be changed to two-line mode for easier viewing and to use larger fonts.

The pitch and volume of the buzz tone on the console can be adjusted by the user.

The following notes refer to Figure 17 on page 71, which illustrates the M2250 attendant console cross-connections.

Note 1: The M2250 is powered by means of the line circuits. In addition to the primary TN, secondary TN, and ASM TN, two TNs are cabled to the M2250 using the +AUX and –AUX leads. The maximum loop length is 3000 ft of 24 AWG wire.

Note 2: When additional options are used (BLF or display backlight option), an additional 16 V DC power supply is required. The 16 V DC source is cabled using +VPS and VPS RTN leads. The maximum distance from the console to the power source is 120 feet of 24 AWG wire. Please note: if both options are installed, only one 16 V DC power supply is required.

Note 3: Nortel recommends that five consecutive TNs on the line circuit be allocated for each console.

Note 4: When used with the ISDLC, the M2250 requires NT8D02 or later.

Note 5: The third TN must be cross-connected to the console cable WH/SL pair whether or not an ASM (Attendant Supervisory Module) is installed. This third TN provides additional console power which is required.

Table 8 on page 73 explains where each M2250 cable pair is connected. Table 9 on page 75 lists the M2250 typical cross-connections.

M2250 configurations

Attendant consoles Page 77 of 504

This section contains operating procedures for the M2250 attendant console. The attendant console faceplate layout is shown in Figures 14 through 16, starting on page 66. Refer to these figures as the basis for component location references throughout this section.

The M2250 attendant console can be configured to operate with the QMT2 feature, which is provided by a QMT2 add-on module incorporated in the console. Instead of having to add a keystrip unit, the technician can set a dip switch on the keyboard/controller Printed Circuit Panel (PCP) to ON (enable QMT2) or OFF (disable QMT2). It is important that the system software configuration and the QMT2 dip switch be set correctly.

For more information, refer to the section on LD15 in the following documents:

• Features and Services (553-3001-306)

• Software Input/Output: Administration (553-3001-311)

QMT2 feature disabled

When the QMT2 feature is disabled, the following conditions apply:

• If the console is not in Shift mode, keystrip AK is inactive.

• If the console is in Shift mode, the keys in strip AK function as Trunk Group Busy (TGB) keys, if configured in the system software.

• If the operator presses any of these keys, the associated trunk group is busied out.

• The triangle points aimed to the left of keystrip AK are never active.

• If the operator presses any key outside keystrip AK when the console is in Shift mode, the console performs the function associated with that key. The Shift indicator remains on.

• The keys in keystrip BK function as Incoming Call Identification (ICI) keys.

Telephones and Consoles Description, Installation, and Operation

Page 78 of 504 Attendant consoles

QMT2 feature enabled

When the QMT2 feature is enabled, the following conditions apply:

• If the console is not in Shift mode, the keys in strip AK and/or BK function as Incoming Call Identification (ICI) keys.

• If the console is in Shift mode, the keys in keystrips AK and BK function as Trunk Group Busy (TGB) keys. That is, they imitate the keystrips of the QMT2 add-on module as follows:

— The LCD indicators pointing to the left indicate busy trunks.

— The LCD indicators pointing to the right indicate incoming calls.

M2250 feature operation

Attendant consoles Page 89 of 504

Time and date

On the M2250, the time and date are automatically downloaded from the system on power-up or console reset. The time and date are downloaded by the switch whenever it runs a lamp audit. Only the visual format can be changed.

Trunk Group Busy indicators

Trunk Group Busy (TGB) indicators show the status of each group of trunks. If a TGB indicator is on steadily, the attendant has busied out all trunks in that group by pressing the Shift key plus the TGB key. If a TGB indicator is flashing, all the trunks in that group are actually busy.

In Supervisory mode, TGB indicators show the status of other consoles in the customer group. If the indicator is off, the attendant position is in a Position

Telephones and Consoles Description, Installation, and Operation

Page 90 of 504 Attendant consoles

Busy mode. When an indicator associated with a particular attendant is on, the attendant is available to service calls.

Note: The M2250 attendant console must be equipped with the Attendant Supervisory Module (NT7G10AA) to allow attendant supervision.

Incoming Call Indicators

Incoming Call Indicators (ICI) display the various types of incoming calls presented to the attendant console. They also indicate the number of calls and the length of time calls have been queued.

• If the indicator is on, one call has been queued for less than a certain length of time (as defined by software).

• If the indicator is flashing, one call has been queued for more than the defined length of time, or there is more than one call in the queue.

Night service/busy

When the Shift key is off, press the Busy key to put the attendant console into Position Busy mode. When the Shift key is on, press the Busy key to put the console into Night Service mode. To return to normal operating mode, press the Busy key again.

In a multi-console system, activating Night Service mode will busy out all attendant consoles in the system.

Enhanced Night Service

This feature allows Public Network (Central Office [CO], Direct Inward Dial [DID], Foreign Exchange [FEX], and Wide Area Telephone service [WAT]) trunks to be assigned to specific Directory Numbers (DN) during Night Service.

With this feature each customer will be able to assign Public Network trunks to one of nine Night Groups. Each Night Group will allow the customer to define up to nine Night DNs. During Night Service incoming calls will be routed to one of the Night DNs defined for the group. The actual DN the call will be routed to is determined by the Night Service Option number selected at that time.

553-3001-367 Standard 3.00 August 2005

Attendant consoles Page 91 of 504

The customer will also be able to define whether Night Call Waiting tone will be given to Night stations. With Night Call Waiting tone allowed, busy Night stations are notified when an incoming call is terminating on them. The incoming call will be queued on the Night station until it becomes idle. When the Night station becomes idle, the incoming call will be presented.

This enhancement allows incoming DID trunks to be queued against busy Night stations, thereby making the operation of the DID trunks the same as for all other Public Network trunks.

Attendant Blocking of DN

The Attendant Blocking of DN (ABDN) feature enables the attendant to block a DN for a telephone from receiving or making calls. This is particularly useful when a caller dials the attendant DN and requests an external (long distance) call. If the caller chooses to disconnect until the attendant successfully places the call, the requesting DN becomes idle and can receive or make calls. Therefore, the requesting DN could be busy when the attendant establishes the requested call.

To prevent the requesting DN from being busy when the requested call is completed, the attendant can block the DN from making or receiving calls. To callers attempting to contact the blocked DN, the line appears busy. To a caller attempting to use the blocked DN, the line is connected to the attendant.

When the attendant completes the external call, the attendant can call the blocked DN and extend the call. This feature applies to both stand-alone and ISDN network environments.

The Attendant Blocking of DN feature is available on the M2250 attendant consoles. It is not valid on M2616 telephones used as attendant consoles.

Attendant and Network Wide Remote Call Forward

This modification to the Remote Call Forward feature (RCFW) allows a user to program a call forward Directory Number from any attendant console or station throughout the network. An RFW key on the attendant console allows an attendant to view any station’s call forward status and to activate or deactivate call forward for a station.

Telephones and Consoles Description, Installation, and Operation

Page 92 of 504 Attendant consoles

Refer to ISDN Primary Rate Interface: Features (553-3001-369) for further details.

Network Attendant Services

This feature allows attendant services to be distributed anywhere within a Meridian ISDN network. If, at the time of an attendant request, attendant services are not available at a station’s local node, connection to an attendant at a remote node takes place. Call treatment is the same as for a connection to a local attendant node.

Call processing

The attendant answers an incoming call by pressing the flashing loop key.

To answer a specific type of incoming call, press the ICI key next to the appropriate ICI indicator. This removes the call from the queue and presents it to the attendant.

ICI key assignments

An ICI key may be assigned more than one call type. Refer to Software Input/ Output: Administration (553-3001-311). If the Attendant Call Party Name

Display (ACPND) feature is equipped, all incoming calls are displayed by calling party name or external call source. The following examples list possible ICI key assignments:

• Attendant Intercept indicates that a call is being made by a station to a facility to which that station is restricted, and the call has been routed to the attendant console.

• Listed Directory Numbers (maximum four) indicates that a call is being made to an attendant console associated with one of the listed directory numbers.

• Dial 0 indicates that a station that is not fully restricted has dialed 0.

• Fully Restricted Station indicates that a fully restricted station has dialed 0.

• Foreign Exchange indicates that the incoming call is from a foreign exchange.

553-3001-367 Standard 3.00 August 2005

Attendant consoles Page 93 of 504

• Wide Area Telephone Service indicates that the incoming call

originated at a wide area telephone exchange.

• Recall

indicates that a camped-on call or a call extended to an idle station

has not been answered for 30 seconds or that a station is recalling the attendant.

• Call Forward indicates that the call is being forwarded to the console

from a station within the system.

• Tie Trunk indicates that the incoming call is on a tie trunk.

Operating keys

The operating key/lamp strips CI/CK, DI, EI, and FI/FK allow the attendant to process calls from the console.

Key/lamp strips CI/CK and FI/FK have permanently assigned functions as given in the following list.

• Release

allows the attendant to release a call presented to the console.

When the LCD associated with the RLS key is lit, it indicates that no incoming calls are being presented to the console.

• Loop Keys/Lamps allow the attendant to answer and originate calls

from the console. The first call in the incoming queue is automatically presented to an idle loop key. Subsequent calls are queued and presented to a loop key when a loop becomes idle. Call selection is made by pressing the required ICI key. This action causes the call, which was automatically presented to the loop key by the system, to be replaced by the selected incoming call. In all cases, when the loop key is pressed, all ICIs go dark except the one associated with the call presented to the loop key.

• Position Busy enables the attendant to put the console in Position Busy

mode. All calls directed to a console in Position Busy mode are redirected to a free console in multiconsole installations or to the night connection in single console installations. When a console is in Position Busy mode, “BUSY” is shown on line 4 of the display.

Telephones and Consoles Description, Installation, and Operation

Page 94 of 504 Attendant consoles

• Night Service permits incoming calls to the attendant to be routed to a preselected station. The Night Service key enables the attendant to assign the Night Directory Number (DN) and to initiate Night Service. When assigning the Night Service DN, “NIGHT” flashes on line 4 of the display. When Night Service is on, “NIGHT” appears without flashing on the display.

• In a multiconsole system, activating Night Service will busy out all attendant consoles in the system.

• Hold allows the attendant to hold an active call at the console while serving other calls.

• Conference permits the attendant to set up a conference of up to five conferees plus the attendant.

• Release Destination

allows the attendant to release the called party from

a call held at the console while holding the calling party.

• Release Source allows the attendant to release the calling party from a call held at the console while holding the called party.

• Signal Source and Destination allows the operator to recall either party to a call held on the console.

• Exclude Destination excludes the called party from an established call held at the console, allowing the attendant to speak privately with the calling party.

• Exclude Source excludes the calling party from an established call held at the console, allowing the attendant to speak privately with the called party.

Feature keys

Any of the keys on keystrip FK can be assigned any of the optional features in the list that follows except the Barge-In and Busy Verify features. These require five LCD indicator states (off, on, and flash at 30, 60, or 120 impulses per minute). If Barge-In or Busy Verify is required, it must be assigned to keys FK-0 and FK-1.

553-3001-367 Standard 3.00 August 2005

Attendant consoles Page 95 of 504

All other features may be assigned to any of the keys on strip FK. Refer to Software Input/Output: Administration (553-3001-311) for additional information. The following are some of the more common feature keys:

• Attendant End to End Signaling enables the attendant to send dual tone

multifrequency (DTMF) signals to either the source or destination party.

• Busy Verify allows the attendant to confirm that a station returning a

busy signal is actually being used.

• Barge-In allows the attendant to enter an established trunk connection

for the purpose of talking to one or both parties.

• Paging allows access to a public address facility.

• Speed Call allows numbers to be dialed automatically by pressing the

SPEED CALL key and dialing a 1- or 2-digit code.

Call Waiting indicator

The Call Waiting indicator indicates that there is a queue of calls to be answered. When one or more calls are waiting, “CW” appears on line 4 of the display. The CW display changes from steady to flashing when waiting calls exceed a certain number or when a call has been waiting longer than a specified time.

The maximum number of waiting calls and the maximum hold time for each waiting call to be answered can be set with a data administration task. Refer to Features and Services (553-3001-306) for more information.

An optional buzz is available to indicate when the first call enters the queue. The number of waiting calls can be viewed on the LCD screen by pressing a key assigned on the attendant console. On the M2250, the number of waiting calls can be displayed continuously on line 4 of the display, if defined in LD15 and selected from the Options menu.

Alarm indicators

Alarms appear on line 4 of the display. “MN” indicates a minor alarm condition; “MJ” indicates a major alarm. A minor alarm is an indication of a minor system failure affecting a limited number of lines or trunks. A major alarm indicates that Emergency Transfer may have been initiated. See “Emergency Transfer” on page 96.

Telephones and Consoles Description, Installation, and Operation

Page 96 of 504 Attendant consoles

Emergency Transfer

If a major equipment or power failure halts local call processing, preselected CO trunks are automatically connected to preselected stations (predetermined and hard-wired at installation time) through relays in the system. Emergency Transfer can also be activated manually by a switch underneath the attendant console.

If the switch is activated while the console has power, the word “EMERGENCY” appears on line 4 of the display.

Attendant Administration

Attendant Administration is an optional feature that allows the attendant to modify some of the features assigned to selected telephone sets within the attendant’s customer group. The attendant can enter a special program mode with an assigned key.

Once in the program mode, the console key/lamp strips have different functions from those during normal call processing. A plastic overlay can be placed over the console keyboard to identify the altered key functions. Refer to Features and Services (553-3001-306) for Attendant Administration description and operating procedures.

Collect Call Blocking

The Collect Call Blocking feature enables a system administrator to block long distance collect call service calls on incoming Direct Inward Dialing (DID) and Public Exchange/Central Office trunks (analog or DT12).

Under the following conditions, the system sends a special answer signal to the Central Office to indicate that collect calls cannot be accepted:

• The Collect Call Blocking (CCB) package 290 is enabled.

• The incoming route has CCB enabled via the CCB prompt in the Route Data Block.

• The call is answered by a CCB user (that is, Collect Call Blocking Allowed Class of Service or option).

553-3001-367 Standard 3.00 August 2005

Attendant consoles Page 97 of 504

Classes of service and prompts are provided which enable administrators to inhibit specific users from receiving collect DID and Central Office calls. These can be configured for the following:

• PBX and BCS through the Collect Call Blocking Allowed/Denied (CCBA/CCBD) option

• Attendant and Network Alternate Route Selection calls on a per customer basis through CCBA/CCBD option

• Automatic Call Distribution (ACD) queues through the CCBA prompt

• Direct Inward System Access (DISA) through the CCBA prompt

• Tandem calls dialed with Coordinated Dialing Plan (CDP) (Trunk Steering Code, Distant Steering Code) through the CCBA prompt

• Tandem non-CDP calls through the CCBA prompt in the Route Data Block from the outgoing trunk route

When a call is answered by a CCB user, the system sends the CCB answer signal in place of the regular signal for incoming DID/CO calls from the routes with CCB enabled. If the call is a collect call, The CO will disconnect the call.

Alarm Management

The Integrated Alarm Management feature is a series of subfeatures which improve the handling of key alarm messages generated by the system and its Application Processors.

It also clarifies existing alarm messages and makes attendant console alarm lamp signals more meaningful. The system has three levels of alarm: critical, major, and minor. The attendant console alarm lamp will light when critical alarms occur.

Digital Trunk Interface – CIS

The CIS DTI trunk feature provides connectivity between the system and digital trunks used in the Commonwealth of Independent States (CIS).

The CIS 2 Mbps DTI feature enables the system to connect digital DID/COT trunks to a CIS Local Central Office and to a CIS Toll Exchange (through Local CO and Public Network, or directly for incoming toll call connections).

Telephones and Consoles Description, Installation, and Operation

Page 98 of 504 Attendant consoles

This link supports DID/COT trunking types, and requires that the system be equipped with at least one CDTI2/CSDTI2 digital trunks pack, as well as associated software.

DPNSS Executive Intrusion

Executive Intrusion (EI) allows an originating party to break into an established call between two other parties (the wanted and the unwanted parties) under certain circumstances. If intrusion succeeds, a conference takes place on the wanted node between the originating, wanted and unwanted parties.

EI succeeds in breaking into the call based on comparisons between the Intrusion Capability Level (ICL) of the originating party and the Intrusion Protection levels (IPL) of the wanted and unwanted parties.

The system provides Executive Intrusion from attendant consoles. Executive Intrusion from Telephone Sets is not supported. However, a Meridian 1, CS 1000M, or CS 1000S PBX will accept an EI activation request from an ordinary set on a third party PBX.

Attendant Monitor

Attendant Monitor is a customer-defined option which allows the attendant to monitor – in listen only mode – any established call involving a set or trunk on the customer with or without the connected parties being aware that monitoring is taking place (depending on the configuration of the customer tone option).

The differences between the existing Busy Verify and Barge-in features and the Attendant Monitor feature are the following:

• Attendant Monitor provides a listen only path for the attendant.

• There is no click sound given to the connected parties upon Attendant connection when the no tone option is configured.

• The tone to the connected parties may or may not be given depending on the customer tone options for Attendant Monitor.

• The display (if there is one) on any of the parties involved in the calls does not indicate that the Attendant is monitoring.

553-3001-367 Standard 3.00 August 2005

Attendant consoles Page 99 of 504

Busy Verify and Barge-in Enhancement

Attendant Monitor changes the operation of Busy Verify and Barge-in slightly. Tone is now configurable. Busy Verify and Barge-in restrictions relating to the Warning Tone Allowed/Denied Class of Service apply to Attendant Monitor as well.

Attendant Forward No Answer

Attendant Forward No Answer allows two enhancements to existing operations. The first enhancement permits calls presented to the attendant to forward to a second attendant or the night DN when a customer-defined time expires. The second enhancement allows DID or CO calls to any set during night service to disconnect if not answered within a predefined number of ring cycles.

Attendant Forward No Answer is selectable on a customer basis, and is included in the package 134, AFNA.

Semi-Automatic Camp-On

Semi-Automatic Camp-On is an option to the current camp-on operation. When the party to which a call is camped-on becomes free, the attendant is recalled first instead of the wanted party being rung immediately. The modification is implemented under the Semi-Automatic Camp-on (SACP) package.

When an external call is camped on to a busy DN by an attendant or a set, the called party receives a buzz (for digital sets) or a burst of tone (for analog [500/2500-type] sets), indicating camp-on. Without SACP, if the called party becomes idle within a customer-defined time, the camped-on call rings the station immediately.

With SACP, if the called party becomes idle, the camped-on call recalls the attendant instead of ringing the called party. The called party meanwhile is kept busy from receiving any calls (but is still able to originate calls).

A programmable key, the Semi-Automatic Camp-on Recall (SACP) key is included with the SACP feature.When a recall is presented to the console, the RECALL ICI lamp and the SACP lamp light up. After answering the recall from the calling party, the attendant can ring the called party by pressing the

Telephones and Consoles Description, Installation, and Operation

Page 100 of 504 Attendant consoles

SACP key. The attendant can then hold the call on the console, or release the call as usual.

When the attendant tries to present the call (after it has recalled to the attendant) to the wanted party, this party may have originated another call. In that case, the attendant receives the indication that the set is busy, and can then camp-on the call again or release it, as usual. On a second camp-on, the attendant must activate the SACP feature again, if needed.

The SACP feature is active either for all camped-on calls or on a per-call basis depending on the customer option. When the per-call basis is chosen, the attendant activates the feature by pressing the SACP key before camping-on the call. If the SACP key is pressed twice, the associated lamp goes dark, and the SACP feature becomes inactive for the call.

Series Call

The Series Call feature causes a source call (either an attendant-answered incoming call, or an attendant-originated trunk call), that has been extended to an internal destination party, to be recalled to the attendant when the destination party hangs up. The attendant can then send the source call to another destination party. This feature enables a caller to talk to more than one party without having to disconnect and call again. Recall to Same Attendant must be allowed, otherwise the recall is routed to the first available attendant. This process can be repeated for as many destinations as requested by the caller.

A Series Call is canceled if one of the following occurs:

• the attendant presses the SECL key while the associated lamp is lit

• the attendant extends the source to a trunk while the SECL lamp is lit

• the attendant enters Night Service after extending the call and prior to receiving the recall

• the destination is call forwarded to a trunk

• the source disconnects
