Mitel Sx 50 Dpabx Instructions Guide

							General Description 
Generic Module 
2.19 The Generic Module is located on the right side of the Card Frame and connects to 
the Control Card via a 50 conductor ribbon cable. The Generic Module contains 
Erasable Programmable Read Only Memory (EPROM) which stores the system 
software, non-volatile RAM (NW) for the customer database and volatile RAM (VR) 
which stores current call status. The NVR is battery backed by the Lithium Ceil for a 
maximum of 
4,500 hours. Refer to Figure 2-19, Generic Module and Figure 2-20, 
Generic Module Dimensions.

							General Description 
Attendant Console 
2.20 Connection to the DPABX is made via a 3-pair cable. 
The Attendant Console has a 2 line x 40 column Liquid Crystal Display (LCD) which 
facilitates call processing and Customer Data Entry (CDE). The LCD guides the 
attendant by listing the required commands for.. data entry. Refer to Section 
9104-091-210-NA, Customer Data Entry for details. Beneath the’LCD is a row of five 
softkeys; they are not labeled but they perform the functions indicated above them on 
the LCD. The Attendant Console also has 21 hardkeys (Attendant Keys) arranged in 
three rows; their designations are printed above the keys. To the right of the Attendant 
Keys, there is a 4 row x 3 column telephone digital keypad; the keys are markgd 0 to 
9, “N and ^O. To the right of these keys there is a fourth column of keys. These are used 
to adjust the LCD contrast and the bell volume, in conjunction with the STATUS key. 
The Attendant Console is shown in Figure 2-21. 
The handset (or headset) plugs into the left side of the Attendant Console. Two jacks 
are provided allowing connection of a second handset or headset. At least one 
hand/headset is required for Day Service operation (the SX-50 system operates in 
Night Service if the hand/headset is removed; all calls are routed to a Night Inward Dial 
l&rcept Answer Point such as the Night Bells equipment).

’ SYSTEM CONFIGURATION 
General 
4.1 The SXSO system supports typical PABX applications within the following limits: 
Up to 160 lines, which can be: 
l ONS Lines: 16 per slot, up to 160 if slots are available 
l OPS Lines: eight per slot, up to 80 if slots are available 
l DNIC Lines: eight per slot, up to 32 if slots are available 
l COV tin&: eight per slot, up to 64 if slots are available 
Note: The combined total number of COV and DNIC line cards must not exceed eight. 
Up to 32 trunks, which can be 
l LS/GS Trunks: 8 per slot, up to 32 if slots available 
l E&M Trunks: 4 per slot, up to 32 if slots available 
l DID Trunks: 8 per slot, up.to 16 if slots available 
No more than 9 Universal Cards (if slots available), total of 34 modules. Module types 
are: 
l E&M Trunk Module 
l RMAT Module (1 per system) 
l MOH/Pager Module (1 per system)^N 
* An MOH/Pager Module is ignored by software when the Control Card 2 (MCC2) is 
installed. ‘, 
Identifying the Software Revision level 
4.2 Press the Attendant Console STATUS key once. The LCD shows the software 
identifier (e.g. MS%) and maintenance release number (e.g. MRO). Refer to Figure 
4-1, Software Identification.

							General Description 
Identifying Software Without a System Console 
4.3 To identify software without the use of a system console perform the following steps: 
1. Enter 
the programming access code from the test line (SUPERSt 4 and 
SUPERSET 
420 only). 
2. Enter command 999. The LCD display will show the software identifier. 
Card Configurations . 
4.4 
Peripheral cards can be installed in slots one through ten. The SX-50 is virtually a 
non-blocking DPABX. For optimum performance under heavy traffic conditions, it is 
suggested 
that the cards be installed in the following order: 
1. Starting at 
Slot One (1) and proceeding to the right, install the DNIC Line Cards. 
2. Install the COV tine Cards immediately to the right of the DNIC Line Cards. 
3. Install the ONS or OPS Line Cards immediately to the right of the COV Line Cards. 
4. Starting at 
Slot Ten (10) and proceeding td the left, install the LS/GS and DID Trunk 
Cards. 
5. Install any Universal Cards in the remaining slots.

System Operation 
user can enter the number of a programmed register, with no following . The 
contents of that register will be immediately displayed. Again, the cursor will be at the 
left of the display. 
Unlike the Console display, the RMATS terminal displays all 26 digits in the 
Digit 
Comparison Table and the Digit Modification Table. 
There are three additional commands used for programming the Digit Modification 
Table digit strings. These are P (uppercase) for a 5-second Pause, p (lowercase) for 
a l-second Pause, and W for Wait For Dial Tone. 
The Tim-f-Day Table, Commands 701 + 745, must be programmed in order. Refer 
to Section 9104491-220--NA, Automatic Route Selection. 
The backspace key is commonly used to delete ARS digit strings in Command 700. The 
entire digit string must be deleted by applying the backspace key while the cursor is on 
the “Time of Day” field (the terminal must be optioned to allow the backspace key to 
send
