DID (Direct in Dialing) Outside incoming calls connected to subscriber directly without PBX attendant’s help DIL (Direct in Line) DISA (Direct Inward System Access ) DOD (Direct Outward Dialing ) Subscriber calls directly without PBX attendant’s help CO Group Access code It follows flexible numbering and 8-digit sequence of number (Max. 73/25)
Introduction of CO Function I
Basic Concept
Outgoing CO Route Group (max. 72/24) Incoming CO Route Group (max. 72/24) ARS (Alternative Route Selection) Each CO Group access code has 2 ARS and it could be serviced CO access code or CO route group AND (Automatic Network Dialing) Digit Conversion According to 9 class, digit converted (max.16-digit )

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

DID Example
DID Service
• Normal – Service Type : Normal – Check Ring Mode (DNT) – Follow CO Ring Assignment Table
• Destination – Station (with Delay Ring) – Station Group – Announcement Table(CCR) – Announcement Table and Drop – DISA Tone – Direct VM Transfer – Networking Number – Company Directory(USA Only) – Digits
• Related PGM – CO Ring Assignment (PGM167)

• 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)

Incoming Alternative Service
Alternative Service
• Alternative CO Ring Table – System provides additional ring table except CO ring table. – It can be programmed as Alternative Destination, Holiday Destination, ICLI Destination. • Related PGM – Incoming/Outgoing Alternative Destination (PGM169, 173) – 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)
