Intercept Treatments

Intercept Treatments (for when a call fails) are set in LD 15, INT_DATA, and printed in LD 21.
An intercept situation is shown with the 4 possible call originators: Stations, Attendants, TIE or DID trunks. eg:

CTVN OVF OVF OVF ATN  - intercept treament for calls to vacant numbers (CTVN) for the four call types.

Call Types:

1st	2nd	3rd	4th
Sets/DISA	Attendant	TIE trunk	DID trunk

Intercept to:

• ATN - Attendant
• BSY - Busy tone
• NAP - Not Applicable
• OVF - Overflow tone
• RAN - Recorded Announcement (RANR)
• SRC1-8 - Announcement Source (1-8)
• OFA - Overflow, then attendant
• BST - Busy Tone

Intercept situations:

Intercept situations and default treatments:

INT	Intercept situation	SET	ATT	TIE	DID
ACCD	Access denied	OVF	OVF	OVF	ATN
CTVN	Call to vacant number	OVF	OVF	OVF	ATN
MBNR	Call to Maintenance busy numbers	OVF	OVF	OVF	ATN
CTRC	Toll restricted call	OVF	NAP	OVF	NAP
CLDN	Calls to a Listed DN	NAP	OVF	NAP	NAP
NINV	BARS/NARS invalid calls	OVF	OVF	OVF	ATN
NITR	BARS/NARS invalid translation calls	OVF	OVF	OVF	ATN
NRES	BARS/NARS restricted calls	OVF	OVF	OVF	ATN
NBLK	BARS/NARS blocked calls	OVF	OVF	OVF	ATN
MFVO	MFC Call to vacant office	OVF	OVF	OVF	ATN
MFVN	MFC Call to vacant number	OVF	OVF	OVF	ATN
MFCG	MFC Congestion	OVF	OVF	OVF	ATN
LCKT	Call to a lockout set	BSY	BSY	BSY	BSY
UBRI	Universal BRI	OVF	NAP	NAP	NAP
RCLE	Redirection count exceeded	ATN	OVF	ATN	ATN
CONG	Congestion tone	(OVF) BSY
DLT	Direct Inward System Access Lockout	(OVF) ATN or OFA
LLT	Flexible Line Lockout	(OVF) ATN or OFA
DNDT	Do Not Disturb intercept treatment	(BST) ATT or RAN

For RAN, a RAN Route (RANR) is required
MFC = Multifrequency Compelled Signaling

Vacant Number Routing:

Note: the NET_DATA block overrides the INT_DATA block. For example, when VNR (vacant number routing) in the NET data block is set to YES (and configured with an RLI), the call no longer follows the CVTN setting in the INT data block. This is a way of sending vacant number calls to the NRS (via IP trunks) for end-point resolution. If you are not using this feature, make sure VNR is NO to have calls follow the CTVN entries.

Intercept Example:

In the following example, we will make DID calls to vacant numbers (CTVN) hear a busy signal rather than goto the attendant.

First, print the data block and check how its set now: CTVN for DID is set to ATN (attendant)...

LD 21

REQ: prt
TYPE: int

TYPE INT_DATA
CUST 00
ACCD OVF OVF OVF ATN
CTVN OVF OVF OVF ATN     <----- calls to vacant numbers
MBNR OVF OVF OVF ATN
CTRC OVF NAP OVF NAP
CLDN NAP OVF NAP NAP
NINV OVF OVF OVF ATN
NITR OVF OVF OVF ATN
NRES OVF OVF OVF ATN
NBLK BSY OVF OVF ATN
MVFO SRC1 SRC1 ATN ATN
MFVN SRC1 SRC1 ATN ATN
MFCG SRC2 SRC2 ATN ATN
LCKT BSY BSY BSY ATN
RCLE BSY BSY ATN ATN
CONG BSY
DLT OVF
LLT OVF
DNDT BSY

Second, change the data block to the desired treatment: OVF = overflow (busy signal)...
