The HSU-AD 530/35 Card supports two RS-530 or V.35 CPE devices. The selection of RS-530 or V.35 is made on a port-by-port basis using on-board switches as described below. This card also supports V.25bis dialing (an inband dialing protocol) and RS-366 dialing through separate DB-15 RS-366 jacks on the card. The HSU-AD 530/35 Card also has a proprietary inband performance monitoring system.

1.2.4.1HSU-AD Card Jumper/Switch Settings

Set the card switches for operation of ports 1 and 2 in either the RS-530 or V.35 mode. These switches are shown in Figure 1-2; they are factory-set for RS-530 operation. To change a port to V.35 operation, reset its switch as shown. The ports can be set individually for either RS-530 or V.35 operation, but once you set them, they remain in that mode until the slide switches are reset. RS366 Dialing Port #1 and RS366 Dialing Port #2 are dialing ports for Port #1 and Port #2 (HSU RS530/V.35) respectively; they serve no other purpose.

1.2.6Four-Port HSU 530/35 Card Description (821570)

The four-port HSU 530/35 Card supports four RS530 or V.35 data ports. The selection of RS-530 or V.35 is made on a port-by-port basis using on-board switches.

CAUTION!

If used in a system using a T1 “Line Code” other than “B8ZS,” HSU card ports assigned to multirate circuits greater than or equal to 4 or more consecutive time slots at 64kbps must have DTE connected to the port prior to activation. Failure to attach DTE will cause a false carrier alarm.

1.2.6.1Four-Port HSU Card Jumper/Switch Settings

The four-port HSU 530/35 Card has four slide switches that must be set for the proper type of interface (either RS-530 or V.35) on ports 1 through 4 of the card. Figure 1-4 shows these switches, which are factory-set for RS-530 operation on both ports. To change a port for V.35 operation, reset its associated switch as shown. Ports can be set individually for either RS530 or V.35 operation, but once set, they remain in that mode until the slide switches are reset.

Note: When setting switch to V.35 mode it unbalances the CTS Lead. It does not change the voltage levels of the driver output. (The Personality Module will do the same thing as setting the switch).

CAUTION!

If used in a system using a T1 “Line Code” other than “B8ZS,” HSU card ports assigned to multirate circuits greater than or equal to 4 or more consecutive time slots at 64kbps must have DTE connected to the port prior to activation. Failure to attach DTE will cause a false carrier alarm.

1.2.7.1Features of the Four-Port HSU*4E 530/35 Card (821660)

This enhanced HSU card is a derivative of the 821570 card, with better clock performance and a true V.35 interface. The functionality of the 821660 will be the same as the 821570 except for the addition of a receiver clock invert option.

The 8216xx can be used in any DDS application where the circuit has many timeslots (>24). The enhanced clock jitter provides better tail-circuit performance. Additionally, the transmit and receive clock edges can be individually selected (refer to Tx and Rx CLOCK PLRTY descriptions later in this chapter).

1.2.7.2Four-Port HSU Card Jumper/Switch Settings

The four-port HSU*4E 530/35 SS Card has a dip switch that must be set for the proper type of interface (either RS-530 or V.35) on ports 1 through 4 of the card. Figure 1-5 shows the dip switch, which are factory-set for RS-530 operation on both ports. To change a port for V.35 operation, reset its associated switch as shown.

Ports can be set individually for either RS530 or V.35 operation, but once set, they remain in that mode until the slide switches are reset.

1.2.8V.35 Personality Module (1251)

When using the two-port HSU 530/35, HSU-AD 530/35, and four-port HSU 530/35 Cards, you may want to connect the RS-530 output jack to RS-232 external equipment (for all of these cards). The V.35 Personality Module is a adapter module that plugs into the female DB-25 port and connectors, then attaches via a male/female connector to the external CPE device. Figure 1-6 shows this module.

Note: The CPE connection cables should be less than 25 feet long. For RS232 operation, the recommended maximum cable length is less than 25 feet, and the speed should not exceed 56 kbps.

STATE

The State setting determines whether the port is active or inactive. An inactive port does not occupy time slots on a WAN link. Set State to standby (stdby) for ports you are not using or have not yet configured. Set it to active (actv) for ports that are ready for use. The control leads assume the status shown in Table 1-6 for the different states.

WAN/SRV

The WAN/SRV setting identifies the card to which the output of this port is directed. If wan is chosen, the data from this card port will be directed to a WAN port (the options are w1-1 to w4-2).

If user is chosen, the data will be routed to another HSU Card. First, highlight the selected user slot (U1 to U8). Then, if there is a compatible HSU Card in that slot, the system will ask for the number of the port to which you want to connect (1 to 2 or 1 to 4). Type in the number of the port desired. If a number higher than the possible number of available ports is chosen (e.g., 9), the system will automatically select port 1 on the destination user card.

Note: The serv setting is not available for the HSU-T V11 and HSU-T 35 Cards.

MODE

The Mode parameter appears only for the HSU-T V11 and HSU-T 35 Cards. It allows you to identify how the HSU port appears to the device on the other end of the interface cable. The dce option causes the port to be recognized as a DCE (data circuit-terminating equipment) device. The dte option causes the port to be recognized as a DTE (data terminal equipment) device.

Note that the choices appearing for some of the parameters that follow will depend on whether you choose dce or dte as the Mode. Those parameters and their available settings are described below.

HSU Card

TS

The TS (time slot) setting identifies the time slots on the WAN link when wan is the WAN/SRV setting. Unlike other user cards, the HSU Card can use many time slots on a single WAN port to create a super-rate circuit for an individual HSU port. One or all DS0 time slots on a single T1 or E1 link can be assembled for use by an HSU port in order to satisfy the speed requirements of the DTE.

The time slot numbers range from 1 to 24 for T1 links and 1 to 31 for E1 links. However, time slot 16 is not available on E1 links programmed for CAS or CCS signaling. Figure 1-9 shows the display when table is selected. Using the space bar to select and deselect the time slot, this example shows time slots 11 to 16 on WAN 1-1 assigned to this port. The time slot assignments do not have to be contiguous on any card port.

Note: Do not change this parameter when the HSU Card is linked to an ISDN-PRI connection.

HSU Card

HSU Card User Screens and Settings

RATE

The Rate setting allows you to select the bandwidth for all time slots assigned to this port. The available options are 56k or 64k. This selection is multiplied by the number of time slots assigned to the port, to define the overall port speed. For example, if you choose 64k as the port Rate and assign four time slots to that port, the overall port speed is 256 kbps.

Tx CLOCK

The Transmit Clock (Tx CLOCK) setting identifies the clock source for the SD (send data) signal from the external CPE. The int (internal) setting requires an external DTE to synchronize its transmitted data with the clock on the SCT leads. The ext (extended) setting requires the DTE to synchronize its transmitted data with the clock on the SCTE leads.

Use ext with a long cable run to ensure the data and clock are in-phase when they arrive at the system. The DTE must loop back the clock on the SCT leads to the SCTE leads.

If ext is selected but the system does not detect an incoming clock on the SCTE leads, the HSU Card automatically generates an internal clock. If this clock is not synchronized with the incoming data, reset the CLOCK PLRTY option to synchronize the clock and data. The Tx CLOCK PLRTY option settings are described in the next paragraphs.

On the HSU-T V11, HSU-T 35 and HSU*4E 530/35 SS Cards, the Transmit Clock option can be set only if the Mode for the card port is set to dce. The default TX Clock setting in the dce mode is int. For a dte port, the only available setting is n/a.

Tx CLOCK PLRTY (821660 card)

The Transmit Clock Polarity (Tx CLOCK PLRTY) setting provides another way to compensate for long cables in those cases where the DTE equipment does not provide SCTE. When you choose inv (inverted mode), the relationship between the clock and data is altered to compensate for long cable runs that the data signals must traverse between the card port and CPE. When you choose norm (normal), the relationship between the clock and data is unchanged. If you use inv, set the Tx CLK (Transmit Clock) option above to int (internal).

On the HSU-T V11, HSU-T 35 and HSU*4E 530/35 SS Cards, the Clock Polarity setting above can be set only if the port Mode is set to dce. The default setting in that node is norm. For a dte port, the only available setting is n/a.

DATA PLRTY

The Data Polarity (DATA PLRTY) option allows you to either send all data bits to the network as normal ones and zeros, or to invert all bits in the transmitted data stream. Choose norm (normal) to leave the transmitted data intact; or, choose inv (inverted) to invert all outgoing data. This can be helpful in ensuring minimum-ones density transmission over T1 links when

Data Cards

HSU Card

the data contains long strings of zeros. Inverting the zeros reduces the likelihood that the composite T1 stream will not meet minimum-ones density requirements. Both systems of the end-to-end HSD circuit path require the same DATA PLRTY option setting.

On the HSU-T V11 and HSU-T 35 Cards, the Data Polarity option is available only if the port Mode is set to dce. The default setting in that mode is norm. For a dte port, the only available setting is n/a.

CTS

The Clear To Send (CTS) setting controls when data is sent. Some DTE equipment must receive a CTS signal before transmitting data. Set the CTS option to perm (permanent) to make CTS permanently High (asserted). Choose rlocal (remote-local) to allow RTS to control both CTS on the local DTE device and RLSD on the remote DTE device.

Choose to ignor (ignore) to always force CTS Low (negated). Set the CTS option to locl (local) to make CTS follow RTS from the local DTE.

On the HSU-T V11 and HSU-T 35 Cards, the CTS settings are used only if the port Mode is set to dce. The default setting in that mode is perm. For a dte port, the only available setting is n/a.

CTS DELAY

The Clear To Send (CTS) Delay setting delays changes in the CTS signal in the local mode. Enter the value you need in milliseconds. The available options are 0, 30, 60, and 100 ms. If you do not know what value you need, start with 0 (zero) ms and increase the value gradually until you no longer experience problems. The CTS option above must be set to locl before the CTS DELAY setting has any effect.

On the HSU-T V11 and HSU-T 35 Cards, the CTS Delay settings are used only if the port Mode is set to dce. The default setting in that mode is 0 (zero). For a dte port, the only available setting is n/a.

LOCAL LB

The Local Loopback (LOCAL LB) option activates a loopback on the selected card port. Choose the dte setting to loop the outgoing data from the external DTE device back to the DTE receiver. This loopback (see Figure 1-10) allows you to check the local cabling and most of the circuitry in the HSU Card. It also disconnects the incoming data from the far end.

HSU Card

On the HSU-T V11 and HSU-T 530/35 Cards, the same choices above appear if the port Mode is set to dce. For a dte port, the choices are dce, local, and off. The dce loopback is functionally identical to the dte loopback depicted in Figure 1-10, and the local loopback is the same as the net loopback depicted in Figure 1-11.

LB GEN MODE

The Loopback Generation Mode (LB GEN MODE) setting defines the type of inband loop-up and loop-down codes that will be sent to the remote equipment. Three industry-standard codes are supported: dds, which sends a DDS-compatible latching loopback code in each of the DS0s that make up the circuit; v.54, which is compatible with CCITT V.54 standard and ft1, which is compatible with ANSI Fractional T1 standards. The final option, perf (performance data), activates an 8 kbps performance data monitoring channel (isolated from the total bandwidth of the circuit) that collects end-to-end performance statistics from a local HSU Card to a remote HSU Card.

On the HSU-T V11 and HSU-T 35 Cards, the same choices above appear if the port mode is set to dce. For a dte port, this setting is always n/a.

LB GEN

If you selected v.54, ft1, or perf as the Loopback Generation (LB GEN) mode setting, the Loopback Generation setting allows you to send an on (loop-up command) or off (loop-down command). If you selected dds as the Loopback Generation mode, this setting allows you to define the type of DDS loopback that you wish to generate. The four options are ocu (Office Channel Unit), dsu (Data Service Unit), csu (Channel Service Unit), and ds0 (a full 64 kbps loopback). Figure 1-12 through Figure 1-14 show where these loopbacks occur. You can also turn all DDS remote loopbacks off.

Note that you cannot perform loop-up and loop-down commands on more than one port of the same card simultaneously. You must finish all loopback operations on one port before starting them on another port.

On the HSU-T V11 and HSU-T 530/35 Cards, the same choices shown above appear if the port Mode is set to dce. For a dte port, the choices are llb (local loopback), rlb (remote loopback), and off. The llb setting loops the incoming signal from the network back toward the network and far end. This loopback occurs at the HSU-T V11 or HSU-T 35 Card. The rlb performs the same loopback at the far-end card.

LB DET

Depending on the selection you made for the Loopback Generation mode above, the HSU Card port will respond to any of the loopback codes generated by a remote system. The Loopback Detection (LB DET) setting lets you enable or disable this capability on each card port. However, this setting does not affect local loopback commands from a local control terminal.

Choose off to have the system ignore remote loopback commands. Choose on to make the system monitor the card ports for loopback commands sent from the remote equipment. Note that the system will detect only the loopbacks in the format selected as the LB GEN mode. When the system detects a loopback code, it loops the data back until the remote equipment releases the loopback. The w/to (with time-out) setting is the same as on, except that after 10 minutes the system automatically releases the loopbacks initiated by the remote equipment.

On the HSU-T V11 and HSU-T 35 Cards, the same choices above appear only if the port Mode is set to dce. For a dte port, this setting is always n/a.

ISDN CONN

This option is not available with this host release.

EER (821360 card)

The Excessive Error Rate (EER) parameter is only available on the HSU-AD 530/35 Card. This setting defines an error rate threshold which, when exceeded, causes an alarm to be declared. If the number of errors exceeds this threshold, an E will be placed in the Status Column of the card’s Performance Monitoring Screen. The available options are from 10e-4 (one error in 10,000 bits) to 10e-9 (one error in 1,000,000,000 bits), or none. Choose none if you do not want to report alarms for excessive error rates.

Rx CLOCK PLRTY (821660 card)

The Receive Clock Polarity ( Rx CLOCK PLRTY) setting provides another way to compensate for long cables in those cases where the DTE equipment does not provide SCTE. When you choose inv (inverted mode), the relationship between the clock and data is altered to compensate for long cable runs that the data signals must traverse between the card port and CPE. When you choose norm (normal), the relationship between the clock and data is unchanged. If you use inv, set the Tx CLK (Transmit Clock) option above to int (internal).

Only the HSU*4E 530/35 SS Card supports this parameter. For all other HSU’s this setting is n/a. The default setting in that node is norm. For a dte port, the only available setting is n/a.

BERT

The Bit Error Rate Tester (BERT) sends a data pattern and measures the bit error rate (BER) on the selected HSU port. The patterns that can be selected are off, mark (1111), space (0000), 1:1 (1010 alternating), 1:7 (0100-0000), 511 (511 test pattern), qrss (quasi-random signal source), and 2047 (2047 test pattern).

On the four-port HSU 530/35 Card, selecting the ds0 pattern will display another set of BERT patterns. Additional non-latching loopback patterns are ff (1111-1111), 7e (0111-1110), 32 (0011-0010), 40 (0100-0000), ocu-a (ocu-alternating byte), csu-a (csu-alternating byte), dsu-a (dsu-alternating byte), csu1a (csu–one repeater–alternating byte), and csu2a (csu–two repeater–alternating byte). The results of the alternating patterns (ocu-a, csu-a, dsu-a, csu1a and csu2a) appear in the Test Screen.

Also note that the Bit Error Rate Tester is supported on the HSU-T V11 and HSU-T 35 Cards only if the port mode is set to dce in their Card Main Screens.

1.3.3HSU Dial Screen

A call profile template must be downloaded to the HSU port before it can be used as a dialing resource by DTE devices, such as video codecs or LAN routers.

Each DTE device is assigned a telephone number which is stored on the HSU port Dial screen. This number will be used as the “Calling Number” on the download copy of a call profile template for outgoing calls. Additionally, this number is used by other DTE as the “Called Number” when placing a call to that device (an incoming call).

PRIMARY #

The Primary Number is the main phone number used to route incoming calls for this HSU port. This number must be unique throughout all HSU ports system.

HUNT GROUP #

The Hunt Group Number is an optional number that makes the port of this HSU part of a hunt group. The hunt group number is the same for all HSU ports in the hunt group. The system will route any incoming calls placed to the hunt group number to the first available HSU port in the group. A hunt group number must be within the range of numbers assigned by the carrier controlling the ISDN switch.

AUTO ANSWER

The Auto Answer feature allows the HSU port to automatically answer an incoming call either the primary number or the hunt group number. A value of yes means the equipment will always accept the incoming call for an unbusy port. A value of no means the HSU will not answer the call until the attached DTE responds with DTR high. RS530 ports will respond to auto answer with the Ring Indicator lead, V.35 ports must be set to auto answer for this version of the software.

ANSWER TIMEOUT

If the user chooses no for Auto Answer (above), the Answer Timeout parameter tells the system how long to wait for the DTE to raise DTR after the call has been sent to the DTE. This parameter is measured in seconds, and the valid choices are 1-60.

DIAL TRIGGER

The Dial Trigger tells the 821360 HSU card when to initiate dialing (see Dialing with High Speed Data Cards later in this chapter). In order for dialing to be initiated, there must be a call profile active for this HSU port.The values are n/a (all other HSU cards), off (do not dial any calls), dtr (dial the active call profile when the DTE raises DTR), rs366 (trigger dialing on this port when RS366 commands are received on the associated RS366 port) and v.25b (trigger dialing on this port when V.25bis commands are received on the associated V.25bis port).

ESCAPE CHARACTER

The Escape Character is the character used by RS366 dialing as a special character to initiate the dialing command (see next section). The options are: *, #, 5, 6, 7, 9, 0, 00.

IMUX PRIMARY #

The IMUX Primary Number is the main phone number used to route incoming IMUX calls for this HSU port. This number must be unique throughout all HSU ports in the system. The number must be within the range of numbers assigned by the carrier controlling the IDSN switch.

IMUX HUNT #

The IMUX Hunt Number is an optional number that makes the port of this HSU part of a hunt group. The hunt group number is the same for all HSU ports in the hunt group. The system will route any incoming IMUX calls placed to the hunt group number to the first available HSU port in the group, provided there is an available IMUX engine. A hunt group number must be within the range of numbers assigned by the carrier controlling the ISDN switch.

IMUX ADD #

The IMUX Add Number is the second number used to synchronize IMUX bandwidth. An IMUX call is placed to the primary number which begins to synchronize the call. Part of that synchronizing process is to report the additional number to the calling IMUX card. The calling IMUX card then dials the IMUX additional number to set up the rest of the bandwidth needed before completing the call. If there is no additional number, the IMUX card will synchronize the call on the primary number only.

CURRENT PROFILE

The Current Profile indicates if a call profile is loaded into the HSU port’s dialing memory. The options for this parameter are none (indicating that the copy of a call profile template has not been downloaded to this port) or loaded (indicating that the copy of a call profile template has been downloaded to this port).

1.3.4HSU Call Profile Screen

Once a call profile is copied from the Interface card template, it can be used by the DTE on the individual HSU port for placing calls to other devices throughout the network. The HSU Call Profile screen is shown in Figure 1-17. Table 1-11 lists the screen of actions and Table 1-12 lists the settings and defaults for each parameter.

HSU Card User Screens and Settings

Once the appropriate information is inserted or changed on the fields of this screen, you can place a call by pressing “D” (Dial) command from the Call Profile screen. When finished, the call can be disconnected by pressing “H” (Hangup) command from the Call Profile screen.

It is important to note that the HSU port used to dial the call must be in the standby (stdby) state when the call is placed. The state changes from standby to active after the call has been placed. The system will not allow a call to be placed from an active port.

Note: Any changes made to the loaded call profile will stay with the call profile copy until changed in a future session. Changes made to this copy will not change the call profile template on the Interface card.

DCHAN

The D Channel number identifies which D Channel to route all outgoing calls that use this call profile. The options are numbers 1-8.

CALLED #

The Called Number is the full telephone number of the device you are calling. Up to 25 numeric characters are allowed, although most calls use only ten digits. This parameter can be overridden on a call-by-call basis when RS366 or V.25bis dialing is used with the Model 8213 HSU card.

CALLED # TYPE

The Called Number Type identifies the type of network used to reach the called phone number. The options are natnl for domestic calls, intnl for international calls, and sbscr for VPN (Virtual Private Network) calls. Your carrier can provide more detail about this option.

CALLED # PLAN

The Called Number Plan refers to the type of numbering plan used to reach the device you are calling. The options are unkwn, isdn, phone and privt. Your carrier will provide more detail about this option.

CHANNEL RATE

The Channel Rate selection specifies the bandwidth to be used by the call. Different carriers support different rates, so it is important to check with your carrier before setting rates greater than 64Kbps. When using any Channel Rate other than MRate, the system knows the size of the bandwidth required and will automatically select the rate multiplier. If MRate is selected, the rate multiplier must be entered by the user.

The u (unrestricted) and r (restricted) in these selections are for data calls. An unrestricted call means the user can send any type of data information in the circuit. A restricted call means the user is responsible for maintaining the ones-density-integrity of the T1 data stream.

Note: Channel Rates of 1536r and 1536u require the use of NFAS.

If the IMUX CALL field is set to yes (see below), the channel rate shows either 56, 64 or H0 (384K).

RATE MULTIPLIER

The Rate Multiplier parameter is automatically set depending upon the Channel Rate (other than MRate or an IMUX call) chosen in the previous paragraph. Valid entries for MRate are 2-24. If an incorrect rate multiplier is input, the carrier equipment will reject the call.

If the IMUX CALL field is set to yes (see below), the channel rate shows either 56, 64 or H0 (384K).

IMUX CALL

The IMUX Call field indicates whether this is an IMUX call or a regular ISDN call. The options are no and yes. If yes is selected, the Channel Rate and Rate Multiplier selections will change (see above).

Since IMUX calls cannot be broadcast, if IMUX call is yes, the user will not be able to use the Broadcast Phones option mentioned later in this section.

SERVICE

The Service parameter is entered only if call-by-call service selection is supported on the D channel selected in the DCHAN parameter above. If call-by-call service selection is provisioned on the selected D channel, the first service type is entered in this field automatically. Valid service codes are those that were entered for this D channel in the Services subscreen of the D channel configuration screen.

To change this selection, highlight the selection with the cursor and press the <Enter> key. A list of all service options for this D channel will appear at the bottom of the screen. Move the cursor to the appropriate selection using the right and left arrow keys and press the <Enter> key again when the correct choice is highlighted.

CALLING #

The Calling Number is the phone number of the calling party that is presented to the called party when the incoming call is delivered. (This feature is often known as Automatic Number Identification or “ANI”).

If the user wants the system’s main (billing) number to be presented to the called party, this field must contain a number of up to 25 digits. If the user wants the specific phone number of the HSU port making the call to be presented, this field must be left blank.

CALLING # TYPE

The Calling Number Type identifies the type of network used by the calling party. The options are natnl for domestic calls, intnl for international calls, and sbscr for VPN (Virtual Private Network) calls. Your carrier will provide more detail about this option.

CALLING # PLAN

The Calling Number Plan refers to the type of numbering plan used by the calling party. The options are unkwn, isdn, phone and privt. Your carrier will provide more detail about this option.

PRESENT. INDCTR

The Present Indicator field determines whether or not the calling number may be displayed to the called party. The selections are yes and no.

BCAST. PHONES

The Broadcast Phones parameter allows the user to select the use of the Broadcast Option (See the following page). The selections for this parameter are no and yes.

1.3.5Broadcast Screen

One of the special features of the HSU Call Profile is the ability to establish a “two-way” connection to the Called # on the Call Profile and broadcast a “one-way” copy of the data sent by the Calling # to a series of additional users. The Bcast Phones parameter must be set to yes to enable this feature.

The Broadcast screen allows the user to specify up to eight additional phone numbers of other devices that will receive data from a “host” HSU port in the system. Figure 1-18 shows one of the ways the broadcast feature could work.

In this example, a two-way call is placed from HSU #1 to the primary number, 510-623-1574 (DEV #1). When the call is connected, the system will dial the remaining secondary numbers until all numbers have been dialed and all available connections are established. In this example, it will dial 415-731-6545 (DEV #2), then dial 415-940-7710 (DEV #3). A notation on the screen will signify if the connection is completed.

When the primary call is disconnected, the broadcast connections are also terminated, however secondary callers can disconnect with no disruption of service to the primary or secondary calls.

Selecting no on the Bcast Phones parameter on the Call Profile screen will disable this feature while keeping the list of broadcast phone numbers intact. Figure 1-19 shows the Broadcast screen.

1.3.6Broadcast Connection Status Screen

WHen the main ISDN call is placed, the system will attempt to establish connection with all of the numbers on the Broadcast screen. The Broadcast screen allows the user to monitor or change the status of each broadcast phone number on the list. Figure 1-20 shows how the example used in the previous section will look after the call is placed. In this example, the call to 415-731-6545 was “Not Connected” while the call to 415-940-7710 was “Connected.”

If the user highlights the “Not Connected” telephone number on the list and uses the “Connect” command, the ISDN card will attempt to place the call again. The status of the call will change to “Connecting.” When the call is completed the status will change to show “Connected.”

To disconnect one of the Broadcast phones prior to the disconnect of the main call, the user highlights the number and uses the “Disconnect” command. The system will prompt you with a yes/no message before action is taken. When disconnected, the call status will change to “Not Connected.”
