List of Cards9.10 Tables 9.2 and 9.3 provide an alphabetical and a numerical
list of the cards used in the 
OMNI SI PABX for both voice and
data.NOTE: The FB mnemonic, which is placed in front of each card
number, stands for functional board.
The following list, provided for your reference, gives of all the
cards in a 
OMNI SI PABX. Figure 9.8 shows the system data
connections.

NOTES:1. These cards cannot be removed or replaced without removing power from the cabinet in
which the card is located. (Refer to power-down procedures.)
2. These cards cannot be removed without first placing the card position in the maintenance
busy state. (Refer to power-down procedures.)
3.Disconnect the cables from the front of these cards before removing or replacing them.

Level IBFigure 10.2PCM (Pulse Code Modulation) Low-usThe use of time slots permits the system to coordinate the
placement of a phone call:
0 When a call originates, the system assigns a series of memory
locations to the originator within 10 milliseconds after the
phone is taken off-hook. This is called assigning a time slot.

sequences needed to complete a connection. The access

Time Switching10.2 Each group within the system has access to certain time
GKlUpSslots (Figure 10.3).
0 System hardware is divided into six time switching groups:
- Each group has twenty-four time slots.
- The Get Started File has two time switching groups that
correspond with groups A and S.
- The Expansion File has four time switching groups - two
are located in group C and two are located in group D.

TL-130500-1001Group Usage of10.2.1 The OMNI SI software makes extensive use of the time
Time Switchingswitching group division. One such use permits the system to
coordinate the placement of a phone call:
l When a call originates, the system assigns a series of memory
locations to the originator within 10 milliseconds after the
phone is taken off-hook. This is referred to as assigning a
time slot.
l Depending upon the signaling mode used when dialing, and on
the feature invoked by the phone user, the...
