Dial From Station/CO Destination

• LCR for Station – Digit conversion table can be assigned about each station. – LCR can be supported with Digit Conv. Table.

• DID for CO line – Digit conversion table can be assigned about each CO line. – Received Digits from PSTN can be converted to the internal/external Destination – LCR can be supported with transit call.

Digit Conversion

Digit Conversion Usage

Basic Concept

• 9 Digit Conversion Table is provided and there are 300 index in a table• Apply Type – Unconditional / Follow Day/Night/Timed / Follow LCR Time• DNT/LCR Time Table Index – Time table index of System Time Table, NOT ASG-STA/CO Time Table Index• Name – DID Name • Apply Option – All / Station / CO line/ Disable

Digit Conversion Table

Basic Concept

• DID – Digit Conv.(PGM251) • Normal – Ring Assign(PGM167) – DISA/CCR • ICLID – ALT CO Ring Table(PGM181) • Alternative Dest. – ALT Dest. (PGM169) Related to CAUSE

CO Ring & DID Flow

• DID – Service Type : DID – Check Digit Conv. Table

• Digit Conversion Table – Unconditional – Follow D/N/T – Follow LCR

• Destination – Station (with Delay Ring) – Station Group – CCR / Drop – VMIB – ATD Call – CO Access – Page – Speed – CONF Room

DID Service

DID Service

• If DID number is ‘3XXX’, it is converted to ‘1XXX’

• DID number is 3500, it is converted to ‘1000’ in Day, to ‘620-Station Group’ in Night, to ‘670001-CCR 1’ inTimed

• DID number is 3600, it can be routed to specific station, Hunt Group, or VMIB announcement according to the Day/Time zone.

• Set CO Service Type to ‘DID’

• Assign Digit Conversion Table index of CO line

• Incoming call can be routed according to the Calling Party number.

- On System basis, calling party number is checked first (higher priority)

- On DN basis, calling party number is checked again (lower priority, PGM 71 each a station)

ICLID Routing

ICLID Service

• ICLID – Compare CLI – Check Ring Mode(DNT) – Alt Ring Table Index from ICLID Table – Follow Alternative Ring Table

• Destination – Assign Alt. CO Ring Table. – Station – Station Group – CCR – CCR Drop – DISA Tone

• Related PGM – ICLID Table (PGM262) – Alternative Ring Table (PGM181)

CO Hold Recall

1. External party calls station 1000 and talks.2. Station 1000 holds the CO call by pressing [HOLD] button and goes on hook.3. External party hears ‘Normal Hold Tone (CO)’ (PGM 290 – 55) for the tone timer.4. If the tone timer expires, station 1000 receives a hold recall ring.5. If station is under No Answer Forward (Normal, Pilot Hunt, or Preset Forward),

call forward no answer timer (PGM 143 - 4) is assigned. (Default is 15 sec) If call forward no answer timer expires, call goes to the forward destination.

6. Otherwise, ‘Recall Ring (CO)’ (PGM 265 - 4) timer is assigned. If ‘Recall Ring (CO)’ timer expires, call follows “Recall No-Answer” destination of “Incoming CO Line Alternative Destination” (PGM 169)
