FEATURES OF CPC 1. It is based on 80386 microprocessor, a 32 bit microprocessor controller. 2. 2 MB battery backup RAM for customer data. 3. 6 MB flash RAM for system switch and customer data. 4. 2 operator console circuit. 5. 1 conference chip ( 8 party conference) 6. Dial tone and ring tone generation. 7. Music on hold. 8. Performs activities like the call processing , switching, digital console interface, PCM interface, conference function etc. 9. It also hosts bty back up real time clock. it includes a watch dog circuit which starts the system in the event of system hang-up 10. There is supportive circuitry to carry out periodic diagnostics. ALC (ANALOG LINE CARD ) : - It is a 16 port card used to connect 16 ext. numbers for interfacing analogue telephones including Ports and PBTs, one LED for one cct for ON/OFF hook indication. ATC (ANALOG TRUNCK CARD) : - It is a 8 port card which provides terminal for DOT lines, hot lines etc. DTR (DTMF TRANSMIT RECEIVED CARD) : - It is 16 port card used for handling DTMF transmission and reception.
(VG) VOICE GUIDED CARD : - It is a 16 port card. It has 24 prerecorded voice, prompt can be modified. E & M CARD (EAR & MOUTH) : - It is a tie line card exclusively for networking. DLC (DIGITAL LINE CARD) : - Digital line card for 16 digital telephone. POWER SUPPLY CARD : - The power supply unit operates on -48V source. The DC to DC converter generates +5V 20A and -5V 3A. SYSTEM FEATURES : 1. Automatic attendant SVC : - It operates like a round clock, operator quickly and efficiently answers incoming calls and then directs them to their appropriate destinations. it frees employees to perform other tasks. 2. Category bearing: - through programming or data entry at operator console stations can be selectively restricted. 3. Conferencing: - the conference can be set up between minimum 3 parties to maximum of 8 parties with any combination of internal extensions and CO line. The only restriction is to have an at least one internal extension in the conference. 4. distinctive CO /inter com ringing :- incoming CO (central office means trunk line)lines ring with different cadence than do the internal calls users can easily distinguish the type of call. 5. External music: - one port in the system is dedicated for external interface through which music can be fed from and external system. 6. In built diagnostics and self tests: - it incorporates additional hardware which enables of the exchange. The diagnostic procedure is executed periodically and if any test failure is encountered, the same is reported to the following three interfaces. 7. LED mounted CPU board, operator console, PC or VDU connected for maintenance. 8. Live system programming : - programming can be p0erformed without taking the system out of service. 9. Memory protection: - it has its own battery backup to protect the system data in the event of power failure. 10. Metering information: - the system is capable of detecting the battery reversal being sent by the CO, for the first time when the call is established and for the second time when the call is disconnected.
11. Paging: - any of the trunk circuits can be programmed as paging port and public address system can be connected to this port. Using this port, any station user can send messages so that the message will be conveyed to all concerned parties simultaneously. 12. message waiting 13. newwork support 14. programmable class of service 15. software pad lock STD etc lock OPERATOR CONSOLE FEATURE 1. Abbreviated dialing comdt, 2 I/c etc 2. automatic call back ( busy stun/ trunk) 3. call forward 4. call park 5. call pickup 6. call transfer 7. call wait 8. conferencing 9. DND 10.emergency reporting 11. follow me/ remote follow me 12. hands free dialing 13. password setting 14. wake up alarm SYSTEM FEATURE 1. Automatic attendant service 2. category barring 3. conferencing 4. distinctive co/ intercom ringing 5. flexible slot assignment 6. hunting groups 7. paging 8. software pad lock 9. station message detail recording (smdr) 10. time based class of service and forwarding numbers 11. redundancy 12. power fail cut through 13. automatic call back (busy station/trunk) 14. busy over ride (with/ without warning) 15. call consult
SAFETY DEVICES USED WITH BPL EXCHANGE system have the following safety devices 1. 6.3 ampere fuse (power distribution board located at rear panel ) 2. SURGE SUPPRESSOR CARD (ssc) 3. low voltage cut off circuit in PSU 4. 750 ma fuse and res 300 ohm 1 watt in ALC card 5. proper earthing of exchange EXTERNAL LINE PROTECTION 1. integrated protection module (IPM) 2. Protection board frame (PBF) on crone module (GD tubes, movs, thermisters and fuses) SPECIAL FEATURES 1. Call transfer (i) press F fig 2 followed by desired no. (ii) normal push button phones press cradle once and dial desired no. 2. Automatic call back on busy press 5 and place hand set on cradle. 3. Call forward press 62 followed by extn no. 4. Call forward cancel press 66 followed by extn no. 5. Wake up alarm press 71 followed by time in 24 hrs formate. 6. Wake up alarm cancel dial 72. 7. Last call recall dial 73
