IP LDK-20 Programming Manual System Feature

Condition
1. There are 6 LCR modes. The mode is determined by ADMIN 220 – FLEX 1.
-
LCR Access Mode 00 (M00): LCR call is disabled.
- LCR Access Mode 01 (M01): Only Loop LCR is activated.
- LCR Access Mode 02 (M02): Internal LCR and Loop LCR are activated.
-
LCR Access Mode 11 (M11): Loop LCR and CO LCR are activated.
-
LCR Access Mode 12 (M12): All types of LCR are activated.
(When dialing ‘9’ or pressing Loop key, the system will wait next digits to compare LCR table
without seizing CO Line)
-
LCR Access Mode 13 (M13): All types of LCR are activated.
(When dial ‘9’ or press Loop key, the system will seize the first available CO Line and wait next
digits to compare LCR table)
2. The leading digits can be duplicated. FLEX 2 and DMT index make each entry unique.
3. Leading digit table is sorted by leading digits, FLEX 2 in LDT (INT, COL, BOTH) and DMT index.
4. Internal LCR is applied if the dialed digits are matched with one of leading digits and FLEX 2 is
INT or BOTH.
5. Loop LCR is applied if the dialed digits are matched with one of leading digits and FLEX 2 is COL
or BOTH.
6. Direct CO LCR is applied if the dialed digits are matched with one of leading digits and FLEX 2 is
COL or BOTH and the seized CO Line belongs to the programmed CO group in DMT.
7. To work Loop LCR and Direct CO LCR differently with the same leading digits, there should be the
leading digit entry for loop LCR prior to the leading digits for direct CO LCR. It is possible if the
DMT index for loop LCR is smaller than the DMT index for direct CO LCR.
8. While direct CO LCR is applied to ISDN CO, an ISDN Information message with called party IE,
which includes only numbering plan and numbering type, is sent to the network when a user dials a
digit. It is for the network not to disconnect the line.
9. For direct CO LCR, leading digits should be programmed in consideration for the dial tone time
provided by network.
10. Direct CO LCR does not use an alternative DMT index because a CO Line is already seized.
11. LCR always has the higher precedence than flexible numbering plan table.
12.
LCR can be applied to the following cases;
-
Dialing after seizing CO Line by dialing CO Line access code ( 0 or 9 ) only
- Dialing after seizing CO Line by {LOOP} button
-
Dialing without seizing CO Line
- Speed Dial
- Off-net Call Forward
-
Redial (if the previous call is LCR applied)
- ACNR (If the call is LCR applied when activating ACNR)
13. Any leading digit string at the LDT table can be sub-string another leading digit string as ‘012’
and ‘0123’.
14. Capacity for LCR Table:
- 3 Day Zones
- 3 Time Zones
- Number of ‘Dialed Code Bins’: 250 bins
- Number of ‘Modification Code Bins’: 100 bins
- Maximum number of ‘Dialed digits’: 12 digits
- Maximum number of ‘Added digits’: 25 digits
- Alternative DMT index: 1EA
