1.15 Optional Device Features

DISA Busy Mode

If the destination of a DISA call is busy, the call will be redirected to an idle extension ( Hunting Group Set [100]) in the destination's idle extension hunting group ( 1.2.1 Idle Extension Hunting). If no extension in the group is available, or if the destination of the DISA call is not a member of an idle extension hunting group, the call will be handled in one of the following ways, according to system programming ( DISA Busy Mode [506]):

a)Disconnect: The caller hears a busy tone and the call is disconnected.

b)Call Waiting: The called extension hears a call waiting tone if the extension has set Call Waiting.

c)DISA: The following procedure is performed:

1)If the assigned DISA OGM (busy message) has been recorded, the caller hears the DISA OGM (e.g., "The party you called is unavailable..."). If the assigned DISA OGM has not been recorded, the caller hears a busy tone and the call is disconnected.

2)After the busy message has been played, the DISA OGM that was sent before the busy message is sent to the caller again.

3)The PBX waits for the caller to enter a new destination. In this case, the PBX does not accept any Outside Line Access number regardless of the security type.

If the destination is a member of a DISA ring group, DISA Busy Mode will not function for the call. The PBX regards it as unanswered.

DISA Intercept Mode

If the destination of a DISA call does not answer the call within a preprogrammed time period ( DISA Ring Time before Intercept [508]), the call will be handled in one of the following ways, according to system programming ( DISA Intercept Mode [507]):

a)Disconnect: The call is disconnected.

b)Intercept: The call is redirected to preprogrammed intercept destinations in the following priority: DISA IRNA to BV—Day/Night/Lunch [438-440] Flexible Ringing—Day/Night/Lunch [408-410] This is useful for business calls. For example, the call can be forwarded to the operator, a Voice Processing System (VPS) or Built-in Voice Message (BV) automatically.

DISA No Dial Mode

If the PBX does not receive either DTMF (Dual Tone Multi-Frequency) signals or a fax (CNG) tone within a preprogrammed time period ( DISA Wait Time after OGM [505]), or if the PBX does not receive DTMF signals within a preprogrammed time period ( Intercept Time for Internal DISA [515]), the call will be handled in one of the following ways, according to system programming ( DISA No Dial Mode [510]):

a)Disconnect: The call is disconnected.

b)Intercept: The call is redirected to preprogrammed intercept destinations in the following priority: DISA IRNA to BV—Day/Night/Lunch [438-440] Flexible Ringing—Day/Night/Lunch [408-410]

DISA Security Mode

Security can be enabled for the PBX to control the types of calls that can be made by callers using DISA. When the DISA security mode is set to "All Security" or "Trunk Security" ( DISA Security Mode [511]), a caller is required to enter a DISA security code ( DISA Security Code [512]) before making intercom and outside (CO) line calls, or outside (CO) line calls only, respectively. The DISA security code and the number of digits required for the DISA security code ( DISA Security Code Digits [530]) can be assigned by the manager. After entering a DISA security code, if the code is the same as one of the preprogrammed security codes, the caller will hear a short beep. It is possible to eliminate the tone through system programming ( DISA Tone after Security Code [518]).

If the DISA security code is entered incorrectly 3 times when using DISA, a reorder tone will be sent to the caller and the call will be disconnected.
