Type 1 if the speed is 56 kbps.

Type either 2, 3 or 4 if the speed is 64 kbps.

The system compares the speed setting that you assign here with the speed setting in an associated routing pattern. The system compares the two speed settings when calls that attempt to use the data module fail to complete.

The system displays the BCC field if the ISDN-PRI field or the ISDN-PRI Trunks field on the Optional Features screen is set to y.

In the Busy Out field, perform one of the following actions:

• To place the data line circuit (DLC) port in a busy-out state so that calls do not terminate at the data terminal equipment when the DTE control lead to the DLC drops, type y. Use this option for DTEs that are members of a hunt group.

• To keep the DCL .

The system displays the Configuration field only when the KYBD Dialing field is set to y.

• Type y if you want to view and change options from originating or receiving DTEs, such as non intelligent terminals.

• Type n if you do not want view and change options from intelligent devices such as computers.

In the KYBD Dialing field, perform one of the following actions:

• Type y if you want the users to dial calls from a keyboard, and to allow the data module endpoint to transmit and receive text during call origination or call termination.

  If you type y, you must also type n in the Low field in the Speeds area of the Data Module screen.

• Type n if you do not want the users to dial calls from a keyboard. If you type n, the data module endpoint cannot transmit and receive text during call origination and call termination. If you type n, data calls can be answered, but there is no text feedback.

In the Default Duplex field, perform one of the following actions:

• Type full for simultaneous, two-way transmission.

  This is duplex mode.

• Type half for only one transmission direction at a time.

  This is half duplex mode.

In the Default Mode field, perform one of the following actions:

• Type sync for synchronous data mode.

• Type async for asynchronous data mode.

In the Default Speed field, type the data rate. The valid entries are:

• 1200

• 2400

• 4800

• 9600

• 19200

• 56000 when the Default Mode field is set to sync

• 64000 when the Default Mode field is set to sync

Type dte if the Asynchronous Data Unit (ADU) is connected to DTE.

Type dte if the ADU is connected to an information systems network.

The Default Data Applications field identifies the mode that the system uses to originate calls when the calling parameters do not specify the mode. The system also uses the mode to terminate trunk calls that do not have administered connections or for which the bearer capability is unspecified. See the Uniform Dial Plan feature for more information.

In the Default Data Applications field, perform one of the following actions:

• Type M0 to specify mode 0. Use this option for a WCBRI endpoint that the system uses as an administered connection.

• Type M1 to specify mode 1.

• Type M2_A to specify mode 2 asynchronous.

• Type M2_S to specify mode 2 synchronous.

• Type M3/2 to specify mode 3/2 adaptable.

In the Default ITC field, perform one of the following actions:

• Type restricted for a WCBRI endpoint that is an administered connection.

• Type unrestricted for a WCBRI endpoint that is not an administered connection.

The display-only MM Complex Voice Ext field contains the number of the associated telephone in the multimedia complex. The system displays the MM Complex Voice Ext field only when the Multimedia field is set to y.

The field is blank until you type the data module extension in the MM Complex Data Ext field on the Station screen. When you type the data module extension in the MM Complex Data Ext field on the Station screen, the system associates the numbers in the MM Complex Data Ext and the MM complex Voice Ext fields as two parts of a one-number complex. The one-number complex is the extension of the telephone.

If the data module can send bits at speeds less than or equal to 56 kbps, type restricted. If you type restricted in the ITC field, the system uses a trunk group for which the COMM Type field on the Trunk Group screen is set to rbavd or to avd to complete a call from this data module endpoint.

A restricted transmission facility enforces ones density digital transmission. Ones density digital transmission is a sequence of eight digital zeroes that the firmware on the DS1 port board converts to a sequence of seven zeroes and a digital 1.

If the data module can send bits at a speed no greater than 64 kbps, type restricted. If you type unrestricted in the ITC field, the system uses a trunk group for which the COMM Type field on the Trunk Group screen is set to avd to complete a call from this data module endpoint. The value avd in the Comm Type field indicates that the trunk group provides both restricted and unrestricted transmission facilities.

An unrestricted transmission facility does not enforce ones density digital transmission. The DS1 port board firmware does not convert the digital information.

Leave the field blank if you do not want the data module to have an abbreviated dialing list.

Type e if you want the data module to have an enhanced abbreviated dialing list.

Type g if you want the data module to have a group list. If you type g, the system displays a field to the right of the List1 field. If you type g in the List1 field, you must also type a group list number in the field that the system displays.

Type p if you want the data module to have a personal list. If you type p, the system displays a field to the right of the List1 field. If you type p in the List1 field, you must type a personal list number in the field that the system displays.

Type s if you want the data module to have a system abbreviated dialing list.

Type the name of the user who is associated with the data module.

Leave the field blank.

The system displays the Answer Text field only if the KBDY Dialing field is set to y.

The Answer Text field applies to the following call messages:

• Incoming

• Answered

• Disconnected

• Disconnected other end

In the Answer Text field, perform one of the following actions:

• Type y to enable text feedback to the DTE when a user answers a call or the system disconnects a call. The text feedback includes both DLC-generated text and system-generated text.

• Type n to disable text feedback to the DTE when a user answers a call or the system disconnects a call, and when the DTE that answers a call is a computer or an intelligent device. The system still generates the text, but the DLC does not support delivery of the text to the DTE.

The system displays the Connected Indication field only if the KBDY Dialing field is set to y. If the Connected Indication field is set to n, DLC provides the connection indication when the DLC activates the Electronics Industries Association (EIA) 232C control lead.

In the Connected Indication field, perform one of the following actions:

• Type y if you want the system to generate a connected message to the DTE when the system establishes a connection.

• Type n if you do not want the system to generate a connected message to the DTE when the system establishes a connection.

The system displays the Dial Echoing field only if the KBDY Dialing field is set to y.

In the Dial Echoing field, perform one of the following actions:

• Type y if you want the system to echo characters back to the DTE.

• Type n if you do not want the system to echo characters back to the DTE and when an intelligent device provides keyboard dialing.

The system displays the Disconnect Sequence field only if the KBDY Dialing field is set to y.

In the Disconnect Sequence field, perform one of the following actions:

• Type long-break if you want a break that is greater than 2 seconds.

• Type two-breaks if you want a break that is less than 1 second.

The system displays the Parity field only if the KBDY Dialing field is set to y. The DLC generates the parities when the DLC sends call setup text to the DTE. The DLC does not check the parity when the DLC receives dial characters. Select the parity that matches the DTE that connects to the data module.

In the Parity field, type one of the following types of parity:

• even

• odd

• mark

• space

The Permit Mismatch field contains information that is used by an EIA interface to operate at a rate that differs from the rate that is agreed upon during the data module handshake. The rate that is agreed upon during the data module handshake is always the highest compatible rate among the speeds that each data module reports.

The information in the Permit Mismatch field eliminates the need to change the DTE or DLC speed whenever someone, or something, places a call to or from endpoints that operate at a different speed.

When the Permit Mismatch field is set to y, the DLC reports the highest optional speed and all the lower speeds, or the previously selected autoadjust speed, during the handshake process.

• Type y If you want the DLC to operate at the highest selected speed, which is a higher rate than the far-end data module.

• Type n if you do not want DLC to operate at the highest selected speed.

In the Low field, perform one of the following actions:

• Type y if you want the data line circuit to operate at a speed of 0 to 1800 bps.

• Type n if the KYBD Dialing field in the CAPABILITIES area is set to y.

In the 300, 1200, 2400, 4800, 9600, and 19200 fields, perform one of the following actions:

• Type y if you want the DLC to operate at the speed.

  You can choose any of the speeds for the DLC. The DLC matches the speed for the duration of the call.

  If you select multiple speeds, you must also set the Autoadjust field to n and select at least three speeds. The speed of the DTE must be the highest speed that you select. The DTE must have the highest speed because the system delivers feedback to the DTE at the highest selected speed.

• Type n if you do not want the DLC to operate at the speed.

The system displays the Autoadjust field when the KYBD Dialing field in the CAPABILITIES area is set to y. The Autoadjust field applies only to calls that a user originates from a keyboard.

In the Autoadjust field, perform one of the following actions:

• Type y if you want the DLC port to automatically adjust to the operating speed and the parity of the DTE to which the DLC port connects.

• Type n if you do not want the DLC port to automatically adjust to the operating speed and the parity of the DTE to which the DLC port connects.

Leave the field blank if you do not want the data module to have special dialing.

Type hot-line if you want the data module to have hot-line dialing. If you type hot-line, the system displays the Abbreviated Dialing Dial Code (from above list): field. Type the abbreviated dial code in the Abbreviated Dialing Dial Code (from above list): field. Valid entries are 0 through 999.

Type default if you want the data module to have default dialing. If you type default, the system displays the Abbreviated Dialing Dial Code (from above list): field. Type the abbreviated dial code in the Abbreviated Dialing Dial Code (from above list): field. Valid entries are 0 through 999.

To assign a 7500 data module, type 7500.

The 7500 data module supports:

• Automatic TEI

• B-channel, maintenance and management messaging

• Service Profile Identifier (SPID) initialization capabilities.

  BRI voice endpoints, BRI data endpoint, or both BRI voice and BRI data endpoints are assigned to either the ISDN-BRI - 4-wire S/T-NT Interface circuit pack or the ISDN-BRI - 2-wire U circuit pack. Each circuit pack can support up to 12 ports.

  You can administer more than one ISDN endpoint, either a voice endpoint or a data endpoint, on one port. You can administer more than one ISDN endpoint, because BRI provides a multipoint capability.

  For BRI, telephones that have SPID initialization capabilities use multipoint administration. Multipoint administration is allowed only if no endpoint that is administered on the same port is a fixed tie endpoint, and no station on the same port has B-channel data capability. The system restricts multipoint administration to two endpoints per port.

Type data-line to assign a data line data module.

Use the Data Line Data Module (DLDM) screen to assign ports on the Data Line (DLC) circuit pack for EIA 232C devices to connect to the system. The DLC, with a companion ADU, provides a less expensive data interface to the system than other asynchronous DCP data modules.

The DLC supports asynchronous transmissions at speeds of Low and 300, 1200, 2400, 4800, 9600, and 19200 bps over 2-pair (full-duplex) lines. These lines can have different lengths, depending on the transmission speed and the wire gauge.

The DLC has eight ports. The connection from the port to the EIA device is direct, which means that no multiplexing is involved. A single port of the DLC is equivalent in functionality to a data module and a digital line port. The system displays DLC as a data module to the DTE and as a digital line port to the server that runs Communication Manager.

The DLC connects the following EIA 232C equipment to the system:

• Printers

• Non intelligent data terminals

• Intelligent terminals, personal computers (PCs)

• Host computers

• Information Systems Network (ISN), RS-232C local area networks (LANs), or other data switches

Type pdm to assigns a DCE interface for processor data modules or trunk data modules.

Use these screens assign Modular Processor Data Modules (MPDMs) and Modular Trunk Data Modules (MTDMs). Use one screen to assign MPDMs (700D), 7400B, 7400D or 8400B Data Module. Use another screen for MTDMs (700B, 700C, 700E, 7400A). You must complete one screen for each MPDM, 7400B, 7400D, 8400B or MTDM.

The MPDM, 7400B, or 8400B Data Module provides a Data Communications Equipment (DCE) interface. Use the interface for a connection to equipment such as a data terminal, call detail recording (CDR) output device, on-premises administration terminal, Message Server, Property Management System (PMS), Communication Manager Messaging, and host computers. The MPDM, 7400B, or 8400B Data Module also provides a Digital Communications Protocol (DCP) interface to the digital switch.

Note that DCE is the equipment on the network side of a communications link that provides all the functions that are required to make the binary serial data from the source or transmitter compatible with the communications channel.

The MTDM provides an EIA DTE interface for connection to off-premises private line trunk facilities, or a switched telecommunications network and a DCP interface for connection to the digital switch. Note that DTE is the equipment that comprises the endpoints in a connection over a data circuit. For example, in a connection between a data terminal and a host computer, the terminal, the host, and their associated modems or data modules make up the DTE. The MTDM or the 7400A Data Module can also serve as part of a conversion resource for combined modem pooling.
