CIM Card. The FIM II modules are available with ranges of 1 km, 5 km, and 14 km. The FIM II
can connect with a FIM, however the fiber interface module at each end of the fiber cable must
have the same range. The FIM II is ideal for distributed systems (cabinets greater than 10
meters apart).
PRI Card - provides up to two links of ISDN connectivity with the T1/E1 module that is installed
on the PRI card. The PRI card requires LIGHTWARE 17 Release 4 or greater software and a
SX-200 ELx cabinet Rev 4.4 or greater ( PN 9109-600-002-NA).
The SX-200 ELx cabinet Rev 4.3 or less can support a PRI card if you use an RS-232 Adapter
(PN 9109-632-001-NA) to connect the cabinet to the PC. The PRI card can also hold a FIM II
or CIM. A PRI card installed in a control cabinet does not require a FIM II or CIM because the
card connects directly to the backplane of the control cabinet. A PRI card installed in a peripheral
cabinet does require a FIM II or CIM to connect the PRI card to the main control cabinet.
T1/E1 Module - contains two digital trunk connections which can be configured as either having
a T1 style interface (1.544Mbits/s) or an E1 style interface (2.048Mbits/s).The SX-200 only
uses the T1 style interface.The two T1 connections, also referred to as circuits or links, support
48 channels.The T1/E1 module can be programmed for Extended Superframe (ESF) and also
has Channel Service Unit (CSU) functionality. The T1/E1 module is installed on the PRI card
providing PRI connectivity or on the Bay Control Card III providing all the features and
functionality of the T1 card with 48 channels.
DSP Module (Single) - provides 8 CLASS generators for ONS/CLASS sets and provides 16
conference bridges for Record a Call. This DSP module also provides 16 DTMF receivers thus
eliminating the need for a Universal Card. The DSP module sits on the BCC III. For CLASS
functionality, the DSP module must be in the same cabinet as the ONS/CLASS Line card. For
the Record a Call conference bridges, the DSP module must also be in the same bay.
Peripheral Interface Cards - interface trunks and peripheral devices, such as telephones,
SUPERSET telephones, Programmable Key Modules, and datasets to the system. Up to eight
peripheral interface cards (PICs) can be installed in Slots 1 to 8. See PICs, page 53, for a
description.
System Software Storage - LIGHTWARE 19 is provided on a 4-megabyte PCMCIA memory
card (flash card). The core software occupies 2MB and the BCC III software occupies 2MB.
Because the remote software download requires an extra 2MB of free space, the remote
software download of LIGHTWARE 19 must be done in a two-step process.
When the system is powered up, call processing and maintenance software is loaded from
PCMCIA memory to the MCC III RAM. The BCC III software is also downloaded from the flash
card to the BCC III.
Customers with a 2MB flash card are not able to upgrade to LIGHTWARE 19.
Customer Data Entry Storage - CDE software is stored in NVRAM, and can also be stored
on an off-board personal computer. When the system is powered up, CDE software is loaded
from NVRAM to the Main Control card RAM.
Backplane - the Main Control Card III, the Bay Control Card, the PRI card, the Bay Power
Supply, and the eight Peripheral Interface Cards plug into connectors on the backplane.
