SX-200 EL System
The SX-200 EL system contains one control cabinet with the following 
components:

A Main Control Card IIIEL (MCC IIIEL) or Main Control Card IIIELx 
(MCC IIIELx) in slot 12

One Bay Control Card (BCC II or BCC III) in slot 9

One Bay Power Supply

Up to two Control Dual FIM Carriers (CFCII), Control Triple FIM 
Carriers (CFCIII), or Control Triple CIM (CTC) cards in slots 
10 and 11

Up to 1 PRI card in unused slots 10 or 11

Up to two T1 Trunk cards in unused slots 10 or 11 

Up to eight Peripheral Interface Cards in slots 1 to 8.
The SX-200 EL Control cabinet with an MCC IIIEL card or MCC IIIELx 
card supports up to six peripheral bays. The MCC IIIELx card can also 
support up to two SX-200 IP Nodes. The peripheral bays can be SX-200 
EL peripheral cabinets, SX-200 LIGHT peripheral cabinets, SPINE 
Bays, ISDN Network Gateways, or PRI cards.
A seven cabinet system will provide a non-blocking system if a
MCC IIIELx card in the SX-200 ELx cabinet (PN 9109-600-002-NA) is 
installed with each of the following combinations:

Two CFCIII cards with LIGHTWARE 17 Release 3.1 or greater

Two CTC cards set to the triple interface setting with LIGHTWARE 
18 Release 2.0 or greater.The SX-200 IP Node requires LIGHTWARE 19, Release 3.0 
with Feature Level 4 enabled.

A seven cabinet system with a MCC IIIEL card and two CFCIII cards 
provides a system for low traffic configurations such as a hotel/motel 
environment.
The SX-200 EL and the SX-200 ML systems use the SX-200 ELx 
cabinet for the main control cabinet and the peripheral cabinets. 
Located on the rear of the cabinet are connectors for T1 trunks (J5 and 
J6), connectors for PRI maintenance (J10 and J11), a printer port, a 
maintenance terminal, and the SFT (System Fail Transfer) control port.

 IntroductionConnectivity from the Main Control Cabinet
The following cards with an interface module connect the main control 
cabinet to the peripheral bays. The Control FIM Carrier cards support 
fiber connectivity.The Control Triple CIM card and the PRI card support 
copper and fiber connectivity. 

Control Dual FIM Carrier card - allows the fiber connection of up to 
two peripheral bays

Control Triple FIM Carrier card - allows the fiber connection of up to 
three peripheral bays

Control Triple CIM card - allows the copper connection of up to three 
peripheral bays; a copper connection may be substituted with a fiber 
connection

PRI card - allows the fiber or copper connection of one peripheral 
bay
You can have either two or three links to each peripheral bay:

With a MCC IIIEL / ELx control card, the Control Dual FIM Carrier 
card provides three links per peripheral bay

With a MCC IIIEL control card, the Control Triple FIM Carrier card or 
the Control Triple CIM card (set to dual interface) provides two links 
per peripheral bay

With a 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 (set to triple interface) provide three links per 
peripheral bay
If you provide two links to each bay:

Calls must be evenly distributed across all bays

Maximum channel blocking ratio is 0.58. 
						

							Technician’s Handbook
8
If you provide three links to each bay

Maximum channel blocking ratio is 0.94.
Connectivity from the Peripheral Bays
Peripheral bays connect to the main control cabinet with the use of an 
interface module on the Peripheral FIM Carrier II card, Peripheral 
Interface Module Carrier card (PIMCC), BCC III, or PRI card. The 
Peripheral FIM Carrier II card supports a FIM. The PIMCC, BCC III, or 
PRI card support a FIM II or a CIM. A FIM II or CIM sits on a PIMCC 
when the peripheral cabinet does not have a BCC III. 
.
As a guideline to achieve a P.0001 grade of service (one 
failure in 10,000 calls) for a bay connected via a Control 
Triple FIM Carrier, the recommended maximum 
calls/hour is 500 based on traffic tables. With a typical 
call hold time of 2 minutes and 12 seconds the total 
Erlang rate is 18.33 (660 CCS) for the whole bay. The 
half bay would therefore be 9.17 Erlangs (330 CCS) at 
250 calls/hour. It is important that calls be evenly 
distributed across all bays.
Remember to use the same distance variant of FIM or FIM II 
at both ends of the cable. You can connect a FIM to a FIM II.
Remember that the system sees the PRI card as a separate 
bay and therefore a PRI card in a peripheral cabinet must 
always have its own interface module (FIM II or CIM). 
Remember that the CIM suits co-located systems; not remote 
systems. The CIM comes in only one variant. The CIM 
supports a distance of up to 30 meters or 100 feet between 
cabinets.

 IntroductionCabinet Configuration

The SX-200 EL system can have a maximum of seven bays.

The BCC III and the BRI card require LIGHTWARE 18 Release 2.0 
or greater. The BCC III, BRI card, PRI card, and Control Triple CIM 
card require the SX-200 ELx cabinet. 

In a main control cabinet: a FIM II or a CIM never goes on a
BCC III, a FIM II or a CIM can go on a PRI card. 

For CLASS line functionality on the ONS/CLASS Line card, you 
must install a DSP module (single) on the BCC III in the same 
SX-200 ELx cabinet. The ONS Line functionality on the 
ONS/CLASS Line card is backwards compatible with the older 
systems. The CLASS line functionality is dependant on 
LIGHTWARE 18 Release 2.0 or greater.

For CLASS on the trunk side, you can install a LS/CLASS Trunk 
card in the SX-200 ELx cabinet or SX-200 ML (FD) cabinet, slots 
1-8. The LS/CLASS Trunk card requires LIGHTWARE 19 Release 
2.0. Prior to LIGHTWARE 19 Release 2, the system required a 
LS/CLASS module with the SPINE, a T1 (ANI/DNIS), or ISDN BRI, 
PRI, or Network Gateway (CLID and CNID).

A DSP module (single) on the BCC III provides CLASS generators 
for 1-8 ONS/CLASS Line cards in the same bay. System wide, this 
DSP module provides 16 conference bridges for Record a Call and 
16 DTMF receivers.

MOSS System Option 96, Number of Links (0-8) monitors the 
number of T1 links from T1/E1 modules that the system will support. 
This count includes T1 links from the T1/E1 modules on the PRI 
cards and BCC III cards. This count does not include T1 links from 
the T1 cards.

LIGHTWARE 18 Release 2.0 or greater supports a maximum of 8 
T1 links (includes T1 links from T1/E1 modules and T1 cards) in the 
SX-200 EL system. Any bay can support up to two T1 links to a total 
of eight in the system.Remember to program CDE Form 04, Options 71 and 72, to 
match the configuration. 
						

							Technician’s Handbook

LIGHTWARE 17 supports one digital bay with two T1 trunk cards 
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 
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 
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 
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 
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 
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 
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.
