This field is used to limit the voice equipment display to channels associated with a particular service or function. This field is valid only if the Equipment: field is channel. If you leave this field blank, the system does not restrict the display to any one service. A special service name of “*DNIS_SVC” is available. If you enter *DNIS_SVC, the voice equipment display shows the number service based on the calling party’s number. 8 Press F3 (Save). The system saves the display settings to a file and returns to the Display Voice Equipment window with the modified parameters. Equipment Options The equipment options, talk or tdm, indicate to the voice system the functionality of the analog and/or digital circuit cards (also known as voice circuit cards).

If you enter talk, the circuit card indicated is used for speech processing. When you enter tdm, the circuit card indicated is not used for speech processing. If you have an SSP circuit card in the system, it is used for speech processing. > Equipment Options
3 Voice System Administration Voice Equipment Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 149 For E1/T1 circuit cards, the only valid option is tdm. No speech processing function is available. The SSP circuit card performs the speech processing function. For IVP4 and IVP6 Tip/Ring circuit cards, the option can be either talk or tdm. Table 12 on page 149 shows the valid equipment option settings. Note:If a system application uses background speech (or music), changing the equipment option may affect how the callers hears background speech. When the channel is set to tdm , foreground speech plays simultaneously with background speech. (Background speech plays at a lower volume than foreground speech.) If the channel is set to “talk,” foreground speech interrupts background speech. Table 12.

If you specify a circuit card, the option is set for all channels of that circuit card. 4 Enter a single number or range of numbers to select the voice circuit cards or channels to change in the Equipment Number: field, or all (default). 5 Press F3 (Save). The system saves the voice equipment options. Equipment State The equipment states, listed below, indicate to the voice system whether or not a voice circuit card/channel is ready and able to receive calls, process speech, etc. — in other words, whether it can perform the job required of it. The Change Equipment State menu option allows you to change the state, or maintenance state, of a card/channel. Some states are valid only for cards and cannot be used for channels. The following is a description of the different maintenance states for voice equipment:• MANOOS (manual out-of-service) — Indicates the circuit card or channel has been taken out of service with a command issued manually.
3 Voice System Administration Voice Equipment Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 151 Note:E1 (CAS) channel 0 and 16 are used for framing and signaling, respectively. They will always display as manoos even when the circuit card is in service and cannot be changed to inserv. Change an SSP circuit card to the manoos state only when there are no active calls on the system. The manoos state disrupts voice playback on all SSP circuit card channels (if only one SSP circuit card is installed) or negatively affects voice playback performance on all channels (if more than one SSP circuit card is installed).• INSERV (in service) — Indicates the circuit card or channel is in service and able to carry a transaction. • FOOS (facility out-of-service) — Indicates the circuit card or channel has been taken out of service by the voice system because the link to the switch is out of service (not physically connected, switch down, etc.). • BROKEN (broken) — Indicates the circuit card or channel did not pass the diagnostics and has been taken out of service by the system. Channels are placed in the broken state by the system. An administrator cannot change a channel to the broken state. • HWOOS (hardware out-of-service) — Indicates the circuit card or channel is out of service due to one or more of its dependencies being out of service, broken, or not physically connected.
3 Voice System Administration Voice Equipment Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 152 • NETOOS (network out-of-service) — For digital circuit cards/channels only: Indicates the system is ready for the channel to go inserv, but is waiting for the network switch to also be ready for the channel to be inserv. Channels may freeze in this state if the switch is not ready for the channel to be inserv. As indicated in the list, some maintenance states are reserved for the voice system only. A system administrator cannot place the equipment in these states. However, a system administrator can place the equipment into the manoos state, and then into the inserv state. See Table 13 on page 152 for a description of the valid administrator changes. Table 13.

Type a single number, a range of numbers, separated by commas or spaces, or all (default). 5 (Optional) Enter Yes or No in the Change Immediately: field. If you enter Yes, active calls on the specified equipment are disconnected abruptly. If you enter No, the state is changed after all current calls end. The changes may not be displayed immediately if you use the No value. If you leave this field blank, the No value is used as the default. 6 Press F3 (Save). The system changes the maintenance state of selected voice equipment. Suggestions for Changing the Maintenance State of Channels Use the following information to help you determine why a channel may be placed in a given maintenance state.Manoos E1/T1 Channels Using Line Side E1/T1 ProtocolCertain switches, or switch configurations, cannot remove a large number of channels from service in a timely manner. Therefore, a delay has been added to the /vs/data/mtc.rc file to change the time between taking a channel out of service and taking the next channel out of service for a E1/T1 circuit card using Line Side E1/T1 protocol. To change this delay for a circuit card using
3 Voice System Administration Voice Equipment Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 155 Line Side E1/T1 protocol, add or modify the following line in the /vs/data/mtc.rc file: LST1_D_REMOVE_DELAY= xxx where xxx is the amount of delay in milliseconds. The default is 200. Manoos E1/T1 Channels Using E&M Protocol The following suggestions apply only to individual manoos E1/T1 channels using the E&M protocol. Other E1/T1 protocols provide the ability to remove individual channels from service. At times, you may want to limit the number of calls the system handles by removing some of the E1/T1 channels from service. Removing E1/T1 channels, however, may negatively impact the system if the switch uses an inappropriate hunting pattern. The E&M protocol does not allow you to remove individual channels from service. If a switch using the E&M protocol does not recognize that a channel is in a manoos state, it continues to route calls to that channel. The system thus returns a busy signal to the caller if the switch directs the call to a manoos channel. For some hunting patterns (for example, those using a round–robin pattern for new call delivery), this is not desirable. With round–robin style delivery, the switch routes a new call to the next channel in the hunt group. When the switch reaches the end of the group, it starts again at the beginning. Consequently, the caller may receive a busy signal even though there may be other idle channels that are in service.
3 Voice System Administration Voice Equipment Intuity™ CONVERSANT® System Version 7.0 Administration 585-313-501 Issue 3 January 2000 156 Ideally, the switch should use all inserv channels before attempting to use any manoos channels. You can force the switch to use inserv channels before using manoos channels by requesting a switch hunting pattern that always scans for idle channels starting at the beginning of the hunt group. On a 4ESS switch, for example, this is achieved by requesting a “trunk hunt without memory.” You can then limit the number of simultaneous incoming calls by placing the least–used channels (channels at the end of the hunt group) into the manoos state. A new call is routed to a manoos channel only if all inserv channels are being used. Manoos E1/T1 ChannelsWhen all channels on a E1/T1 circuit card are in the manoos state, the circuit card generates a BLUE alarm to the switch. Calls are not routed to any of the channels on that E1/T1 circuit card. Manoos Tip/Ring Circuit CardCertain switches or switch configurations cannot remove a large number of channels from service in a timely manner. Therefore, a delay has been added to the /vs/data/mtc.rc file to change the time between taking a channel out of service and taking the next channel out of service for a Tip/Ring circuit card. To change this delay for a Tip/Ring circuit card, add or modify the following line in the /vs/data/mtc.rc file: TIP_RING_REMOVE_DELAY=xxx where xxx is the amount of delay in milliseconds. The default is 0.
