Table 4.29 Memory 1.0 Megabyte (MEM4) PCB (S30819-Ql775-X-*-8900) 
DESCRIPTION: The MEM4 PCB, shown in Figure 4.44, provide 1.0 megabyte of dynamic Random Access Memory (RAM) 
and its supporting logic to store system data. The memory is organized as 512K words X 16 bits/word, 
and divided into 64K byte pages. Memory write protection is provided in 1K word segments. MEM4 is 
arranged for battery backup memory protection to safeguard stored data during short term power out- 
ages. Also, an Error-Correcting Code is provided to correct any single-bit errors and detect double-bit 
errors existing in a word. 
1. Switches. None, 
2. Strapping Options. MEM4 PC8 Vl and V2 must be strapped as follows to provide for 1.0 mega- 
byte of memory: 
Vl strapped between 1 and 2 
V2 strapped between’ 2 and 3 
OBSERVATIONS: Check LEDs for normal indications (Refer to Maintenance and Troubleshooting Section) 
OBSERVATIONS: None. 
INSTALLATION 
PROCEDURES: Locate in basic shelf slot number 27.

DESCRIPTION: 
. . The MEM3 PCB, shown in Figure 4.45, provide 256 kilobytes of dynamic Random Access Memory (RAM) 
and its supporting logic to store system data. The memory is organized as 128K words X 16 bits/ word, 
with memory write protection provided in 1K word segments. MEMB is arranged for battery backup memory 
protection to safeguard stored data durin short term power outages. Also, an Error-Correcting-Code

Table 4.31 Line/lhmk Unit Control (LTUC) PCB (S30810-Q428-X- * -8900) 
DESCRIPTION: The LTUC PCB. shown in Figure 4.46, provides the tim.ing signals necessary to address a line/trunk 
unit. It multiplexes and demultiplexes both signal and voice highways. It also provides fault monitoring 
and reporting of failures associated with the 128.ports it handles. 
1. Indicators. Three red LEDs, designated PRS, ALMO, and ALMl, provide visual indications of ex- 
isting malfunctions as follows: 
a. Protection Restore Signal (PRS), when steadily lit, indicates that one of the following mal- 
functions is present: 
1. No common control on line. 
2. +12Vdc under voltage. 
3 -5Vdc under voltage. 
4. -48Vdc under voltage. 
Note: The PRS is delayed 40 ms (nominal) after the occurrence of any 
one of the previous conditions: 
b. Alarm 0 (A&IO), when steadily lit, indicates that one of the following malfunctions is present: 
1. Loss’of CLK-A (2.048MHz clock) of common control 0 
2. Loss of SYP (4ms time pulse) of common control 0 
3 Loss of SYNR (ring sync) of common control 0 
c. Alarm 1 (ALMl). ALMl is not used in the SATURN IIE 
2. Switches. None. 
OBSERVATIONS:

PROCEDURES: 3. Strapping Options. None.

4.08 Attendant Console. The attendant console is used handling special system functions such as paging, message 
primarily to answer external calls (i.e., incoming trunk calls) and waiting and conference calling. A maximum of 12 attendant con- 
extend such calls to the appropriate internal stations. The con- soles can be interfaced with a particular system. Refer to Table 
sole may also be used to assist in placing outgoing calls and 4.32 for furthei information on the attendant console. 
DESCRIPTION: 
Table 4.32 Attendant Console (L30808X5130&% * -8900) 
The attendant console, shown in Section 2.00, is a desk-top unit with which the attendant processes 
calls and accesses special system features using pushbutton keys and an alphanumeric display. It is 
46.99 cm (18.5 in.) wide, 13.08 cm (5.15 in.) high, 
and 26.47 cm (10.42 in.) deep. A telephone handset 
is furnished with the console. An optional headset may be substituted for the handset. 
*’ 1. Indicators. None. 
2. Switches. None. 
3. Strapping Options. None. 
OBSERVATIONS: 
INSTALLATION 
PROCEDURES: None. 
1. Connect the modular coiled cord to the handset and console. 
2. Connect the modular line cord into rear of console and a standard modular jack receptacle. Check 
that the connections in the modular jack receptacle coincide with those shown in Figure 4.47. 
3 Insert the appropriate key labels into the plastic caps and lock into their corresponding positions 
in the console. 
4. After the system has been tested, perform the appropriate MDF crossconnections to one PIMD 
circuit per console. Refer to Section 600 in this practice for details.

SECTION 5.00 SYSTEM SIGNAL AND POWER/GROUND CABLING ARRANGEMENTS 
5.01 General. This section provides the signal and pow- 
er/ground-cabling arrangements for the SATURN IIE System. 
Tables 5.00 and 5.01 list all the cable reference numbers used 
throughout this practice. The tables provide point-to-point ca- 
ble terminations and refer users to the appropriate cabling 
illustration for quick reference. The following illustrations are 
included in this section: 
NOTE: When an LTU shelf is not equipped its correspond- 
ing signal cable connector on the basic shelf must 
: have a Berg jumper inserted across pins 29 and 30 
in order to suppress LTU shelf failure alarm. The 
connectors are designated as follows: ’ c. Basic shelf connectors J57 and J59 , jumpered if LTU3 
shelf is missing.
