Checking the FIM/CIM Carrier Cards
1. Verify that the cards with the interface module are installed in the cor-
rect card slot for the assigned bay.
2. Verify that the interface modules in the main control cabinet are
correctly connected to its peripheral bays.The configuration positions
are hard coded in the software.
3. Verify that the same distance variant of FIM is installed at each end
of the link.
4. Verify that the dip switch on the Control Triple CIM card is set
properly. Open switch 4 to set the card as a triple interface card and
close switch 4 to set the card as a double interface card. Opening
another switch substitutes a CIM circuit for the add on FIM II.
5. Verify that the PRI card in a peripheral cabinet has its own FIM II or
CIM.
6. Verify the System Options 71 and 72 in CDE Form 04.
7. Verify that the configuration in a seven cabinet system meets your
needs.
 With an MCC IIIEL control card, the Control Triple FIM Carrier
card and the Control Triple CIM card provide two links per
peripheral bay. Blocking may occur if two T1 trunk cards are
installed in a peripheral bay that connect to the Control Triple FIM
Carrier or the Control Triple CIM card.
 With an MCC IIIELx control card (installed in a SX-200 ELx
cabinet PN 9109-600-002-NA) the Control Triple FIM Carrier card
and the Control Triple CIM card provide three links per peripheral
bay. The MCC IIIELx card supports a non-blocking seven cabinet
system.
Setting the Control Triple CIM card as a triple interface card
without a MCC IIIELx provides a system for low traffic
configurations such as hotel/motel. For heavy traffic
conditions a MCC IIIELx should be used.
Place the first FIM carrier card or Control Triple CIM card in Slot
10; the second FIM Carrier card or Control Triple CIM card in
slot 11.
