Checking the T1 Card, T1/E1 Module,
and the PRI Card
In the SX-200 EL system, LIGHTWARE 17 supports one digital bay
n
with two T1 trunk cards and the other digital bays with one T1 trunk
card to total a maximum of seven T1 trunk cards.
LIGHTWARE 18 and greater supports a maximum number of eight
T1 links in the SX-200 EL system. These links can be from the T1
cards and from the T1/E1 modules. Any bay can have a maximum
of two T1 links to a total of eight T1 links in the SX-200 EL system.
The system (with MOSS option, Number of Links 0-8) allows a
n
maximum of eight T1 type links. Included in the count are T1 trunks
from the T1/E1 module on the BCC III and the T1 ISDN links from
the T1/E1 module on the PRI card.
The BCC III supports one T1/E1 module that provides one or two T1
n
links. The SX-200 ML system supports a maximum of two T1/E1
modules with a system maximum of four T1 links. The SX-200 EL
system supports a maximum of seven T1/E1 modules with a system
maximum of eight T1 links.
The T1/E1 module has two LT/NT connectors (jumpers), one for
n
each T1/E1 link. These connectors must be set to the NT position
(the default setting) for T1/D4 functionality.
If you install a T1 trunk card in slot 10 of a bay, you cannot install a
n
peripheral interface card in slot 5; if you install a T1 trunk card in slot
11, you cannot install a peripheral interface card in slot 6.
If you program the first T1 link from a T1/E1 module on the BCC III,
n
you cannot install a peripheral interface card in slot 5; if you program
the second T1 link from a T1/E1 module on the BCC III, you cannot
install a peripheral interface card in slot 6.
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 you program the
PRI card as its own bay, the PRI card does not occupy slots 5 or 6
in the bay that the card sits in. The T1 links from the PRI card occupy
the software slots 5 and 6 in its own bay.
The PRI card requires a SX-200 ELx cabinet and a Stratum 3 MCC.
