DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 851 Multifrequency-Signaling-Related System Parameters 17 Tones from CO on Outgoing Backward Calls — Group B Message codes between 1 and 15 display. Assign a meaning to each code. Refer to ‘‘ Definitions of Group I, II, A, and B signals’’ on page 851 for signal type. Definitions of Group I, II, A, and B signals Group I signals Group I signals are a set of forward signals generated by the originating switch. ani-avail Used in Hungary. If this signal is defined and ANI is requested on outgoing R2-MFC calls, ANI is sent to the CO before ANI caller digits are sent. This signal is sent after the ANI caller category signal. ani-not-avail Used on DOD calls in Brazil and Columbia. The switch sends this signal to the CO when it receives an ANI request and the caller’s number is not available. digits 1 to 10 The signals from group I.1 to I.10 are reserved for address digits 0 to 9. drop When this signal is received from the CO, the switch starts the disconnect sequence and drops the call. end-of-ani This signal is used on DOD and DID calls. The switch sends this signal to indicate the end-of-ANI digits when ANI digits are sent to the CO. Valid entries Usage busy congestion free mct tariff-free toll-busy intercept
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 852 Multifrequency-Signaling-Related System Parameters 17 end-of-dial This signal is used when open numbering is used on DID calls. The CO sends this signal to indicate the end-of-dial digits and the switch responds with a request for a group II signal. end-of-digits This signal is sent by the origination switch that makes outgoing calls, sends digits, and receives a next-digit group A signal from the destination switch when there are no more digits to be sent. This signal is also sent when the switch does not have end-of-ani assigned, makes an outgoing call, sends ANI, and receives a call-info-ani group A signal from the destination switch when there are no more ANI digits to be sent. If both end-of-digits and end-of-ani are assigned, the switch uses end-of-ani after it sends the last ANI digit and end-of-digits after sending the last called-number digit. ignored If this signal is received from the CO, the switch sends a corresponding signal (A.1, and so on) but no action is taken in the response and it is not counted as a digit. In Belgium, this signal is not acknowledged. maint-call The CO sends a signal to indicate that a call is a maintenance call and the switch prepares the special maintenance call sequences for the CO. This signal may be used on DID calls in Saudi Arabia. send-congestion When the switch receives this signal from the CO on a DID call, it returns a congestion signal (group A), in compel (not pulse) mode, to the CO. Group II signals Group II signals are a more elaborate set of forward signals generated by the originating switch. attendant If the switch receives this signal on DID calls, the call terminates at an attendant regardless of the extension dialed. On DOD calls, this signal is sent to the CO if the CO requests calling-category information and the originating extension is an attendant. This signal is used on both DID and DOD calls.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 853 Multifrequency-Signaling-Related System Parameters 17 busy-rt-attd If the switch receives this signal on DID calls, the call terminates at an attendant if the called extension is busy or at the called extension if it is not busy. This signal is used on DID calls. data-call This signal is treated the same as the data-verify signal except that it does not require a terminating extension to be a data extension. data-verify If the switch receives this signal on DID calls and the terminating extension is not a data extension, it sends intercept treatment. On DOD calls, this signal is sent to the CO if the CO requests calling-category information and the originating extension is a data extension. This signal is used on both DID and DOD calls. drop When this signal is received from the CO, the switch starts the disconnect sequence and drops the call. maint-call The CO sends a signal to indicate that a call is a maintenance call and the switch prepares the special maintenance call sequences for the CO. normal This signal indicates that the caller is a normal subscriber. If it is received on a DID call, the call is terminated at the called extension. For an outgoing MF signaling call that uses group II signaling, this signal is sent to the CO when the CO requests calling-category information and the originating extension is a station. This signal is used in both DID and DOD calls. send-intercept If the switch receives this signal from the CO on a DID call, it returns group B intercept signal to the CO. toll-auto This signal is used in China. This signal indicates that a call is an automatic toll call. When the call terminates at a busy station and a special busy signal is defined, the busy signal is sent to the CO. You can define the special busy signal by choosing the option toll-busy on the incoming group B signals.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 854 Multifrequency-Signaling-Related System Parameters 17 toll-operator This signal, used in China, is treated as a normal subscriber signal. See the normal definition. Group A signals Group A signals are backward signals generated by the destination switch. send-ani The CO sends this signal to request calling-party category and sends additional signals to request ANI digits. This signal is sent to the CO when DEFINITY ECS requests ANI digits on DID calls. This signal is used on both DOD and DID calls. congestion The CO sends this signal to indicate that it is experiencing network congestion. When the switch receives this signal on DOD calls, the switch drops the trunk and plays reorder tone to the calling party. This signal is used on DOD calls. drop When this signal is sent, the receiving switch starts the disconnect sequence. end-of-dial This signal is sent to indicate the end of the address digit string. For MF group II calls, this signal requests a group II signal and switches the sender over to the group B signaling mode. This signal is used on both DID and DOD calls. intercept The CO sends this signal to indicate the call has been terminated to an invalid destination. When the switch receives this signal on DOD calls, the switch drops the trunk and plays intercept tone to the calling party. This signal is used on DOD calls. resend-digit The switch sends this signal to adjust the outpulsing pointer so that the last digit can be resent again. This signal is used on DOD calls. last-digit The switch sends this signal to adjust the outpulsing pointer so that the last 2 digits can be resent. This signal is used on DOD calls.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 855 Multifrequency-Signaling-Related System Parameters 17 last-2-digits The switch sends this signal to adjust the outpulsing pointer so that the last 3 digits can be resent. This signal is used on DOD calls. last-3-digits The switch sends this signal to adjust the outpulsing pointer so that the last 4 digits can be resent. This signal is used on DOD calls. next-digit The switch sends this signal to request the next digit. This signal is used on both DID and DOD calls. next-ani-digit The switch sends this signal to request the next ANI digit. This signal is used on DID and DOD calls. restart The switch sends this signal to request the whole digit string again. This signal is used on DOD calls. setup-sppath The CO sends this signal to the switch to set up a speech path. This signal is used on DOD calls and on DID calls in Belgium. Group B signals Group B signals enhance group A signals for backward signaling from the destination switch by providing the status of the called party. In addition, if the originating switch uses group II signals, the destination switch answers with group B signals. Group B signals are as follows: busy This signal is sent to indicate that the called party is busy. On DID calls, the signal is sent to the CO if there is no coverage point to terminate the call. If the switch receives this signal on DOD calls, it plays busy tone to the calling party and drops the trunk. congestion This signal is sent to indicate that the system is congested and the call cannot be terminated successfully. On DID calls, the signal is sent to the CO to indicate that a resource is not available. On DOD calls, if the switch receives this signal, reorder tone is played to the calling party and the trunk is dropped.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1.1 June 2000 Screen reference 856 Multifrequency-Signaling-Related System Parameters 17 free This signal indicates that the called party is idle. On DID calls, the signal is sent to the CO to indicate that the called party is idle and the call is terminated successfully. If the switch receives this signal on DOD calls, it connects the trunk to the calling party. intercept This signal indicates that the called party number is not in service or is not correct. On DID calls, if intercept treatment is set to provide a tone, tone is sent to the CO to indicate that the called number is not valid. If the switch receives the signal on DOD calls, the switch plays intercept tone to the calling party and drops the trunk. mct This signal identifies the call as one that needs to be traced by the CO. DEFINITY ECS then generates an MFC Call Trace Backward Signal (administered on the Multifrequency-Signaling-Related System-Parameters screen) during call setup instead of the “free” signal. If the terminating station’s COR has this feature set to y, the CO collects trace information before releasing the calling party. NOTE: If the station’s COR has MF Incoming Call Trace set to y and the “mct” signal is not defined, then the “free” signal is sent. tariff-free This signal is sent when the trunk group provides an “800” service. DEFINITY ECS generates an MFC tariff-free backward signal (administered on the System-Parameters Multifrequency-Signaling screen) during call setup instead of the “free” signal, facilitating CO billing. NOTE: If the trunk is administered as a tariff-free trunk and the “tariff-free” signal is not defined, then the “free” signal is sent. tie-free This signal is used only when an incoming call is received and defined and the incoming facility is a tie trunk. Otherwise, the free signal is used. toll-busy This signal, used in China, is sent to indicate that the called party is busy if the call is an automatic toll call.
