Introduction

The Cisco BTS 10200 Softswitch supports special tones on various subscriber and operator features by sending MGCP messages to the gateways. These tones are based on the information in the following documents:

•Telcordia document GR-506-CORE, Signaling for Analog Interfaces

•Telcordia document TR-NWT-506, Issue 3, Signaling

•Telcordia document GR-590-CORE, Call Pickup Features (FSD 01-02-2800)

•Telcordia document GR-317-CORE, Switching System Generic Requirements for Call Control Using the Integrated Services Digital Network User Part (ISDNUP)

•Telcordia document GR-219-CORE, Distinctive Ringing/Call Waiting (FSD 01-01-1110).

•IETF document RFC 2705, Media Gateway Control Protocol (MGCP) Version 1.0

List of Tones Applicable to Specific Features

Table A-1 lists the tones used with each feature, and the condition that triggers the sending of each tone.

The called party presses Flash button or switchhook to place the current remote station on hold, and hears the stutter tone. The called party has the following options: •Press Flash button or switchhook again to return to the original call. •Dial a designated vertical service code (VSC)—typically *52—to be connected to the new calling party; the first calling party is kept on hold.
	TONES OFF	No tones are played for CW or CIDCW. (Tones are turned off under certain special circumstances.)

CCW	CONFIRMATION TONE	User in two-way call cancels call waiting.
	DIAL TONE	POTS or Centrex user picks up phone to cancel call waiting.
	STUTTER TONE	User places the other party on hold (CHD) and then activates CCW while call is still on hold.

CHD	STUTTER TONE	For Centrex subscriber (controlling party) currently on an active call: The controlling party places the other party on hold by pressing the Flash button or switchhook, and hears the stutter tone. Controlling party has the following options: •Press Flash button or switchhook again to return to the original call. •Dial a designated vertical service code (VSC)—typically *52—hear the stutter tone again, then dial the number of a third party. The first calling party is kept on hold.
	ALERTING PATTERN 1	Alerting pattern (ringing) is provided to the calling party and called party, as applicable, for all reconnect, re-ring, callback and recall scenarios.

(Note that "being rung" should not include being given call-waiting treatment.) •The call has been answered, picked up, or abandoned. •The requesting line is not allowed to pick up the particular call because of being assigned the fully restricted terminating or the denied termination feature.
DPU	STUTTER TONE	User has dialed DPU access code, and DPU access has been granted.
	REORDER TONE	Reorder tone is returned to the user who initiated a DPU request when any of the following occurs: •The dialed extension is not assigned in the business group dialing plan. •The line associated with the dialed extension is not assigned the DPU feature. •The line associated with the dialed extension is neither being rung nor involved in a stable two-way call. (Note that "being rung" should not include being given call-waiting treatment. Note also that DPU should not allow a user to barge-in on the controller of a multiway connection, that is, a call-waiting configuration, a call-hold configuration, or a conference call.) •The call is abandoned by the caller before the DPU request is recognized or has been picked up by a line without DPU assigned. •The requesting line is not allowed to pick up the particular call because of being assigned the fully restricted terminating or the denied termination feature.

MIDCALL	STUTTER TONE	After pressing Flash button or hookswitch and the system acknowledges it is as a valid midcall action.
	ALERTING PATTERN 1	User goes on hook with the other party still on hold; the system provides alerting pattern (ringing).
SC1D-ACT SC2D-ACT	STUTTER TONE	Stutter tone is used once after the user enters the *74 (SC1D activation) or *75 (SC2D activation) to begin the process of collecting the information required to provision one of the speed call slots. After a speed call slot has been successfully provisioned, the user will again receive the stutter tone to signify that the speed call slot was successfully provisioned.
VMWI 3	STUTTER TONE	User, who is subscribed to VMWI service, has a message waiting, but the serving MGW does not have a visual indicator.

1 When more than one condition is listed for a single tone, any one of the conditions can cause the tone to be played. 2 For more information on the screening list, refer to the Cisco BTS 10200 Softswitch System Description. 3 MWI = message waiting indicator; VMWI = visual message waiting indicator.

Tone Frequencies and Cadences

Table A-2 lists the frequency and cadence for tones applicable to subscriber and operator features. Tones are requested by the Cisco BTS 10200 Softswitch and delivered to the subscriber or operator by the MGW. Some MGWs can be provisioned to play tone cadences different than the ones described in this table.
