2.18 Line or trunk cards can be placed in positions identified with 
blue or black colour-coded strips. (Figure 2-l defines card 
positions which may be used). It is recommended that line cards be 
placed in the lowest numbered card positions and trunk cards in the 
highest numbered card positions. 
This arrangement allows ease of identification of card type during 
installation and maintenance. 
2.19 Peripheral Cards. The peripheral cards used in the peripheral 
shelves measure 254 mm (10 inches) high and 330 mm (13 
inches) wide. 
2.20 Digital Interface Card. The Digital Interface Card (DIC) is in- 
stalled in slot 18 of Bays 3, 4 and 5 to interface between the 
MCC and each Peripheral shelf through a PCM cable. Within each shelf, 
speech paths are analog, but speech paths over the PCM cable are 
digital. Figure 2-8 shows the Digital Interface Card. 
2.21 Peripheral Control Card. The Peripheral Control Card (PCC) is 
installed in slot 20 of Bays 3 and 4, to control the interface 
between the analog cards and the DIC on each Peripheral shelf. The 
PCC in Bay 3 controls Bay 3, and the PCC in Bay 4 controls both Bay 4 
and Bay 5.

Connecting Cables 
2.28 The connections between the MCC Control cabinet and the 
Peripheral shelves are made using connector-ended 12-pair 
PCM cables. 
Power Fail Transfer 
2.29 In the event of a major alarm condition, the power fail transfer 
relays located on the Power Fail Transfer (PFT) board, will con- 
nect Central Office (CO) trunks to selected station lines. Any of the 
following conditions will cause power fail transfer: 
a Commercial power failure (if no reserve power supply is used). 
l Common control failure. 
0 
Manual transfer from control cabinet. 
Each SX-200@ cabinet, providing it has an analog Bay 3 (including rear 
door power supply), may be equipped with a 12-circuit PFT board. 
Each Universal cabinet is equipped with one 6-relay PFT card; two 
additional 6-circuit cards can be added. A plug-in Loop Start to 
Ground Start module is available for 6-cct PFT cards. Each PFT relay 
can connect a standard telephone set directly to a CO trunk (dial pulse 
trunks must connect to rotary dial telephones and DTMF trunks must 
connect to DTMF telephones). SUPERSET@ Sets cannot be used for 
PFT. If ground start trunks are used, the PFT telephones must be 
equipped with either ground start keys or loop start to ground start 
converters. Calls in progress when PFT occurs will be dropped; how- 
ever calls made while in PFT mode will not be dropped when the 
system returns to normal operation, but will terminate normally at the 
end of the call. No PABX features are available while PFT is in effect. 
(a) Incoming Calls - After a power fail transfer has occurred, ring- 
ing of extensions for incoming calls is applied directly to the 
selected extension line from the CO. 
(b) Outgoing Calls 
- To place an outgoing call through a ground 
start CO trunk during PFT, press the ground start key, go off-

hook, and dial the required number. With a loop start trunk, go 
off-hook and dial the required number. Since the telephones 
are connected directly to the CO, usual PABX access codes are 
not dialed. 
Relays 
2.30 
Two relays are provided on the receiver module, which can be 
operated under control of the program, to control various sys- 
tem functions, such as night bells or alarms. 
relay contact ratings 90 Vrms at 0.1 A 
48 Vdc at 0.5 A 
Note: This relay contact may be connected only to a secondary 
circuit that has no direct connection to a primary cirucit, and 
receives its power from a transformer, converter, or equiv- 
alent isolation device situated within the equipment. 
Attendant Console 
2.31 
Attendant consoles may be connected to the SX-200@ DIGITAL 
PABX. Two consoles may be connected to a Universal Card, up 
to a system maximum of 11 consoles. Refer to Section MITL9108-093- 
315-NA, Console Description, for a detailed description of the Atten- 
dant Console. 
Reserve Power Supply 
2.32 The reserve power supply for the Control Cabinet is a stand- 
alone, uninterruptible power supply (UPS) or Standby Power 
Supply (SPS) comprising a battery pack, a charger, and an inverter. The 
UPS or SPS backup time is dependent upon the unit selected and the 
capacity of the batteries provided. The unit must be able to provide 
115 Vat at 15A. The Peripheral cabinet can have its own standard 
reserve power supply (in the base of the cabinet), or can be supported 
by an additional UPS. The UPS is an assembly not manufactured by 
MITEL Corporation. 
2.33 Mite1 Corporation has evaluated several Uninterruptible Power 
Supplies (UPS) and Standby Power Supplies (SPS) for this ap- 
plication. Transfer times of SPSs are generally unreliable under all 
conditions of line and load, resulting in dropped calls. However, several 
SPS and UPS do meet all requirements, and are recommended by 
Mitel. Marketing and Sales literature, which is available from authorized 
representatives, identifies the approved products. 
2.34 The UPS should be a true Uninterruptible Power Supply (except 
for the one SPS recommended by MITEL) which always supplies 
the output load from its inverter and which includes a reverse transfer 
switch to automatically bypass the UPS if it fails.

Several recommended manufacturers of Uninterruptible Power Sup- 
plies has provided samples of their equipment which have proved to 
be compatible with an SX-200a 
DIGITAL PABX in laboratory tests. 
Please note that compliance to electrical installation and building 
codes is the responsibility of the purchaser of the equipment. Consult 
local municipal and electrical utility authorities before proceeding with 
the installation of equipment. 
2.35 An Uninterruptible Power Supply (UPS) may have an external 
connection (from an internal relay) which provides a closed 
contact to remotely indicate status or condition. Conditions which may 
be indicated include: 
- an ALARM condition is present within the UPS 
- the UPS is operating from its batteries (probably because com- 
mercial AC power has been interrupted). 
The relay contact may be connected to a remote alarm or to a 
“Contact Monitor” line circuit to promptly indicate the condition. 
Refer to the Manufacturer’s Installation Manual, which describes con- 
ditions that are indicated. Refer to Section MlTL9108-093-105-NA for a 
description of “Contact Monitor” line circuit operation. 
Paging, Music on Hold Equipment 
2.36 The paging equipment and the music source for the ‘music on 
hold’ are located outside the SX-200@ DIGITAL PABX. They 
should be in an environment specified by the individual suppliers of 
the equipment and connected to the SX-200@ DIGITAL PABX through 
the cross-connect field.

E&M Trunk Module 
2.37 The E&M Trunk Module plugs into the Universal Card. It pro- 
vides interface to Types 1 or 5 E&M trunks. The module has a 
power consumption category of 3. Because of this, only three of these 
modules can be used per Universal Card. 
2.38 The E&M Trunk Module is set for the type of trunk in use by 
setting its eight DIL switches. 
2.39 
0 Facilities provided by the E&M Trunk Module include: 
selectable Type 1 or Type 5 signaling 
0 
selectable gain/loss plan for normal of satellite working trunks 
0 
selectable 600 ohm or AT&T Complex termination (350 ohms + 
1000 ohms in parallel with 0.21 bF) 
l selectable 2- or 4-wire transmission 
l on board fiIter/codec for analog/digital and digital/analog con- 
versions (plaw). 
2.40 Types 1 and 5 E&M trunks differ in the signaling applied to the 
E and M leads. In the on-hook condition, the Type 1 interface 
grounds the M lead and leaves the E lead open; the Type 5 interface 
leaves both leads open. In the off-hook condition, the Type 1 interface 
grounds the E lead and applies 
-48 volts to the M lead; the Type 5 
interface grounds both leads. 
Remote Maintenance of an SX-200@ DIGITAL PABX 
2.41 An auto-answer modem must be connected to the remote 
terminal connector on the maintenance panel and a remote 
terminal and modem connected to the local external auto-answer 
modem. Local and remote maintenance are performed in the same 
way; the only difference is the use of modems to extend overall cable 
length. Access is by dedicated trunk. CO trunk using DISA, or by 
Attendant transfer to a station port.
