Octel Overture 200/300 Serenade 3.0

PB60014–01

6.3 APPLICATION

DELA

Application

delays are timing values set in the Octel Overture 200/300. Some of these delays are used to

detect the tone cadence that the PBX provides to the Octel Overture 200/300. The tone cadence indicates

a specific call condition; for example, a ringback tone indicates that the called extension is ringing, and a

busy tone indicates that the called extension is busy

When a PBX type is selected for System Parameter 3 — PBX TYPE/PBX MODEL, the default values

are set to match the tone cadence of the selected PBX. If the PBX type is not in the list provided by

System Parameter 3, select the PBX type

OTHER

. Because the tone-cadence values in that situation are

not known, the Octel Overture 200/300 defaults to generic/industry-standard values; for example, a

1-second-on/3-second-of

f ring cadence, a 500-ms-on/500-ms-of

f busy cadence, and a 250-ms-on/of

f for a

fast-busy cadence. These values could need to be changed to work correctly with your PBX when

OTHER

has been selected.

If the Octel Overture 200/300 can already detect ringback, slow-busy

, fast-busy

, and if configured, double

interrupted ringback, the application delay indexes do not need to be modified. However

, if the Octel

Overture 200/300 detects an answer condition while monitoring single or double interrupted-ringback,

slow-busy

, or fast-busy tones, you must modify the application-delay indexes. The application-delay indexes

that can be modified are described in the How to Modify Application Delays section in this chapter

How T

ones Are Recognized

When

the Octel Overture 200/300 screens a call, it is looking for single- or double-interrupted ringback,

slow-busy

, or fast-busy tones. T

o process the call transfer

, the Octel Overture 200/300 refers to

application-delay indexes 49 through 52. These indexes show the maximum and minimum ON/OFF

periods for any tone.

If the tone cadence detected does not comply with these delays, the Octel Overture 200/300 determines

that the tone is not a single or double interrupted ringback, slow busy

, or fast busy and that the call has

been answered. If this occurs, the message server completes the call transfer

. In a screen display of the

Print T

one (PR

T) and List T

race, an answer condition is indicated.

If the tone cadence is within the values set for delays 49 through 52, the Octel Overture 200/300 then

compares the tone cadence with application-delay indexes 53 through 76 for single interrupted ringback,

double interrupted ringback, slow-busy and fast-busy delays, to determine what the condition is. If it does

not comply with any of these delays, it is assumed that the call has been answered and the Octel Overture

200/300 completes the transfer. Figure 5-2 shows the sequence that the Octel Overture 200/300 follows to

screen calls.



If the PBX provides double interrupted ringback when an internal extension calls another internal

extension, System Parameter 26 — DOUBLE-INTERRUPTED RINGBACK, is set to YES. The

Octel Overture 200/300 looks for a double interrupted ringback versus a single interrupted

ringback when calling an extension.
