LDN Night Connection - Outside L-30
Service Conditions (cont’d)
19. When system is changed from Day Mode to Night Mode while a LDN call is terminating to ATTCON,
the LDN call is transferred to preprogrammed forwarding destination. If the LDN call cannot be
transferred according to normal priority by restriction for the forwarding destination, the LDN call is
processed in order of following precedence:
1. TRUNK ANSWER FROM ANY STATION [T-8] is provided
2. DELAY ANNOUNCEMENT-ATTENDANT [D-144] is provided
3. NIGHT CONNECTION-FIXED [N-1] is provided
Note 6:
When above feature is not set, the LDN call is queued.
Note 7:
The value of 1 is the highest priority, the value of 3 is the lowest priority.
Interactions
1. A maximum of 16 LDNs can be assigned per tenant; each with its own separate destination number.
2. If the outgoing route is busy or if the incoming LDN route is restricted from the outgoing destination route,
the LDN calling party will receive busy tone or will go to TAS, if programmed.
3. If using TYPE: 3 ADC parameter in the ALDN command, the ADC must first be assigned in the ASPD
command. TYPE: 3 must be used for outside numbers greater than eight digits.
Programming
STEP 1: ALDN - Assign LDN number and its transfer destination.
TN: Tenant Number
LDN: Listed Directory Number (must match station numbering plan.)
Night Transfer: Y/N
If no, then LDN will only go to Attendant.
If yes, then the following parameters will be enabled:
TYPE: Night Transfer Type
1: Station number
2: Outside (up to 8 digits)
3: ADC (when more than 8 digits are required)
STN: For Types 1 & 2.
For Type 1, assign station number here.
For Type 2, assign access code and outside number here.
(A CCIS remote office station number can be input here also.)
ADC:
For Type 3.
Input ADC number desired as assigned in ASPD command.
STEP 2: ASPD
- Assign an access code and outside number to an ADC (000-999). This step is required only if
access code and outside number are greater than eight digits.
STEP 3: ACFR
- Assign TSFI: 2 (Night Connection-Fixed) to be allowed CCI: 1 (LDN). This allows LDN to
go to Night transfer destination. Assign TSFI: 5 (TAS) to be allowed CCI: 1 (LDN). This allows LDN
to go to TRUNK ANSWER ANY STATION (TAS). Restrict if not using TAS.
STEP 4: ARRC - The incoming route of the LDN must allow trunk-to-trunk connection to the outgoing
destination route and to the LCR flag route; ARI-D-RES, Direct Connection.
