Sx-200 Ml System Configuration - Mitel SX-2000 EL Information Manual

SX-200 ML System Configuration

The SX-200 ML system is similar to the SX-200 EL system, page 36, except that the SX-200
ML control cabinet uses a Main Control Card IIIML (MCC IIIML), holds one Control Dual FIM
Carrier card or a Control Triple CIM card and supports only one peripheral bay.
Main Control Card IIIML - performs call processing and maintains overall control through
communication with one or two Bay Control Cards. Four megabytes of RAM, one megabyte of
non-volatile RAM (NVRAM), a System ID Module, a DX module, and a Stratum 3 or Stratum
4 clock are part of the Main Control Card IIIML. The MCC IIIML provides tone receivers, seven
DSP receivers, conferencing, and DTMF tone generation.
System Software Storage - LIGHTWARE 19 software 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 software 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.
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.
Bay Control Card - interfaces the peripheral cards with the main control card.The bay control
cards are installed in the main control cabinet and the peripheral cabinet. The SX-200 ML
system can use the Bay Control Card II (BCC II) or the Bay Control Card III (BCC III). The BCC
III may support a DSP module (single), page 39, a T1/E1 module, page 39, a Maintenance
module,, page 37, and a FIM II, page 51, or a CIM, page 51. Note that the BCC III does not
support a FIM II or a CIM in a main control cabinet.
Maintenance Module - This is an RS-232 driver module that sits on the BCC III in the main
control cabinet. This module provides a serial port in the main control cabinet for the
maintenance procedures on the BRI card.
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 be in the same cabinet as the
user's circuit.
Control Dual FIM Carrier Card - supports up to two Fiber Interfaces Module and connects
them to the backplane. It has a 1 km FIM onboard and a connector to plug in a second optional
FIM (either a 1 km FIM or an extended FIM).
Fiber Interface Module (FIM) - supports the transmission of voice and data signals over fiber
optic cables. The FIM plugs into the Control FIM Carrier. Three Fiber Interface Modules are
available with ranges of 1 km, 5 km, and 14 km. Both FIMs at each end of a fiber cable must
be the same type.
