PART 10. ADDING CARDS TO THE SYSTEM
10.1 ADDING STATIONS AND TRUNKS
1. Remove the covers of the system cabinets in order to locate a suitable empty card
slot. Having located a suitable slot, insert the new card into the slot and push firmly
in the middle of both card ejectors on the card to ensure that it is fully inserted into
the back plane connector.
NOTE: While it is possible to insert and remove certain cards with the system switched
on, it is recommended that the system should be switched off whenever possible
before inserting or removing cards.
2. After the new cards are inserted, the system must be told to recognize the new
cards. This is done through the use of MMC 806 Card Pre-Install. Use this MMC for
each new card that is installed.
3. The new cards must be assigned directory numbers according to the system
numbering plan in MMC 724. The technician must know the software port
assignments of the new cards so the ports can be assigned correct numbers. These
software port assignments are detailed in
10.2 GRADING THE iDCS 500 FOR DTMF RECEIVERS
DSP's (Digital Signal Processors) are used in the iDCS 500 system as DTMF receivers.
Considerations must be made when using features of the system that require DSP's.
Different system traffic patterns may affect the availability of common resource DSP's.
Calculating or "grading" these DSP's is required to ensure adequate system
performance. There are 4 DSP's on each cabinet and 12 on each MFM processor
daughter board. These common use DSP's are shared and any card requiring a
receiver will be able to make use of them. After a DSP receives the expected number of
digits it is released and then assigned to the next call.
The following devices require DSP resources to receive DTMF digits: 1. Analog DID, 2.
Analog E&M, 3. Digital T1 DID, 4. Digital T1 E&M, 5. DISA trunks, 6. T1 ANI/DNIS, 7. 8
SLI, 8. 8MWSLI, 9. KdbSLI, 10. FKDBS, 11. 16 SLI, and 12. 16 MWSLI.
EXAMPLE CONFIGURATION: A single cabinet system with 16 single line ports and a
T1 with E&M trunks. There are 4 DSP's on the main cabinet. In this configuration there
would not be enough DSP's to provide an adequate number of DTMF receivers. A MFM
daughter board should be installed to add an additional 12 DSP's making the total
number of DSP's in the system 16.
