LIGHTWARE 17 supports one digital bay with two T1 trunk cards
n
and the other digital bays with one T1 trunk card to total a max of 7.
If a T1 trunk card is installed in slot 10 of a bay, you cannot install a
n
peripheral interface cards in slot 5; if a T1 trunk card is installed in
slot 11, you cannot install a peripheral interface card in slot 6. T1
cards in slots 10 and 11 are seen by the software as slots 5 and 6.
The two T1 links from the T1/E1 module on a BCC III card also
n
occupy slots (in software) 5 and 6. The BCC III only supports one
T1/E1 module.
The BRI card is a low power peripheral interface card (slots 1-8) and
n
requires a BCC III in the same SX-200 ELx cabinet. If the BRI card
is in a control cabinet, the BCCIII must have a Maintenance module.
A cabinet holds a maximum of two BRI cards.
You can have one PRI card in a main control cabinet; up to two in a
n
peripheral cabinet. PRI cards are installed in slots 10 or 11 in the
SX-200 ELx cabinet Rev 4.4 or greater (PN 9109-600-002-NA ). The
PRI card requires a Statum 3 MCC. The system counts the PRI card
as a peripheral bay.
If a PRI card is installed in slot 10, you can install a peripheral
n
interface card in slot 5; if a PRI card is installed in slot 11, you can
install a peripheral interface card in slot 6. Because the system
recognizes the PRI card as a peripheral bay, the PRI card does not
occupy slots (in software) 5 or 6 in the bay that the card sits in.
LIGHTWARE 18 and greater allows a maximum of 4 high power
n
cards in any of the slots 1 through 8 (there are no high/low power
slots).High power cards are DID, Universal, COV and T1.
Low power cards are DNIC, OPS, ONS, BRI, LS/CLASS, and
LS/GS.Unlike the T1 card, the PRI card is a separate bay and is not
included in the count for the 4 high power cards.
If the cabinet has a BCC II, do not install more than seven
DNICs per bay in high traffic applications. If you have more
than seven DNICs per bay keep the device count to 84 or
less. With two T1 cards in a bay, do not add more than five
DNICs or 60 devices. With one T1 card in a bay, do not add
more than six DNICs or 72 devices.If the cabinet has a BCC
III, you can install eight DNICs per bay.
