SATURN IIE EPABX General Description A30808-X5130-AllO-l-8918 Issue 1, May 1986 3.02 Line/Trunk Unit Shelf. The LTU shelf, shown in Figure 3.03, can contain eight channel groups of LTU modules, con- sisting of the DTMF receiver, line, and trunk PCBs, two LineiTrunk Unit Control (LTUC) PCBS, and an LTUPS. The LTUCs interface with the common control area in the bas- ic shelf and communicate with the LTU peripheral PCBs. The LTU peripheral PCBs provide the interface between the SATURN IIE System and the external devices, which include the station lines, trunks, and attendant consoles. All of the types of LTU PCBs used in the LTU shelf and the LTU portion of the basic shelf are listed in Table 3.00. The LTUC cards are assigned to slot 6 and/or 19 of the applicable LTU shelf. As- signment of the other LTU PCBs is as described in the In- stailation document in this series of Practices.

The basic shelf is shown in Figure 3.04. The basic shelf contains seven channel groups of LTU mod- ules and all the PCBs that make up the common control and switching circuitry of the SATURN IIE System. Figure 3.04 shows the locations of all the PCBs in the basic shelf. The common control and switching PCBs are listed in Table 3.01. Note that two RAM printed circuit boards are provided: one 1 megabyte PCB (MEM4) and one 256 kilobyte PCB (MEM3). This is the minimum RAM configuration. Two additional memory slots (for a total of 4) are provided for future inclu- sion of more memory if needed. In case of failure of the com- mercial power source, the Memory Support Module (MSM) protects the data stored in memory for 5 minutes (at present, only three of the memory slots are wired for this protection).

SATURN IIE EPABX A30808-X5130-AllO-l-6918 General Description Issue 1, May 1986 SECTION 4.00 POWER SUPPLIES 4.01 Main Power Section. As noted previously, the SATURN IIE System makes use of distributed power in the cabinet. Several power supplies are used within the system, some in the main power section located at the bottom of the basic cabi- net, some on the LTU shelves (see Figure 4.00). These pow- er supplies provide +5 Vdc, -5 Vdc, +12 Vdc, -12 Vdc, -48 Vdc, and 90 Vat at 20 Hz for ringing voltage. The standard input power for the system is a 110 Vat, 60 Hz commercial source. The main power section consists of the Power System Unit (PSU) and one or two -48 Vdc power supplies: one if there is only the basic cabinet, two if the expansion cabinet is also equipped. (In systems where only the basic cabinet is used, there is a single ac power inlet at the rear of the cabinet; when the expansion cabinet is also used, a second ac power inlet at the rear of the basic cabinet is provided. The Installation practice in this series gives a full description of the steps necessary when making this change.) Two floppy-disk drives (FDDO and FDDl) are located on the same shelf as the main power section. 4.02 Power System Unit. The PSU is an integrated assem- bly containing the following functional elements (described in paragraphs 4.03 through 4.07): a. Basic shelf power supply b. Memory Support Module (MSM), optional c. Control logic d. Ring generator e. Power supply circuit breakers 4.03 Basic Shelf Power Supply. The basic shelf power sup- ply is an ac-to-dc converter that provides +5, -5, +12, and -12 Vdc power to the basic shelf. 4.04 Memory Support Module. The Memory Support Mod- ule (MSM) assembly is an optional battery backup package that provides +5 Vdc to the RAM memory when the commer- cial ac power source fails. In the event of such failure, the battery maintains the data stored in memory for at least five minutes. When the ac power source is restored within this period, the memory does not have to be reloaded from disk; system operation can begin immediately. The MSM is capa- ble of another 5-minute backup cycle after 30 minutes of recharging. (The unit includes the battery charging appara- tus and is under a “float” charge during normal operation.) For power failure periods longer than 5 minutes, program memory is automatically reloaded from floppy disk when pow- er is restored.

SATURN IIE EPABX General Description 4.05 Control Logic. The control logic performs the follow- ing functions: a. Power Failure Interrupt (PFI). Generates a nonmaska- ble interrupt to the CIOP when input power drops to the brown-out level (95 to 97.5 Vat) and returns to nor- mal when power becomes higher than 100 Vat. b. Ring synchronization. Generates the timing signals for operating and releasing ringing relays. c. Ringing/message-waiting control. Selects either ring output or message-waiting output for connection to the ringing bus. d. Fuse alarms. Monitors each fuse z -?d causes an alarm upon any fuse failure. 4.06 Ring Generator. The ring generator is a single- frequency power supply that provides 90 Vat rms at 20 Hz for station ringing, and 97 Vdc (nominal) for message waiting indications. It provides sufficient power to ring up to 42 sta- tions simultaneously (21 stations each on two different phases A30808-X5130-AllO-l-8918 Issue 1, May 1986 of ringing) and to provide a message-waiting indication on 108 stations simultaneously. 4.07 Power Supply Circuit Breakers. There are circuit breakers for each of the ac inputs to the system (e.g., to the basic shelf power supply, each LTUPS, each -48PS etc). 4.08 Line/Trunk Unit Power Supply. The LTUPS module as- sembly is an ac-to-dc converter which provides +5, -5. +12, and -12 Vdc power to its associated LTU shelf. This supply,lo- cated adjacent to the left side of each LTU shelf, powers one entire LTU shelf. 4.09 48-Volt Power Supply. The -48 Volt Power Supply (-48PSn, where n is designated 0 through 1 in the cabinet) module assembly is an ac-to-dc converter that provides two -48 Vdc outputs. One -48 Vdc output is used for talk battery for analog lines (SLTs), and the other -48 Vdc output is used for PlMDlSLMD applications (i.e., powering attendant con- soles and SDTs, respectively) and power input to the ringing generator in the PSU. The system cabinet may contain either one or two -48PS module assemblies: one for the basic cabi- net and a second when the expansion cabinet is equipped. 4-3 (4-4 blank)

Two FDDs are used as random- access storage devices, each using a floppy disk as the back- up memory storage medium. The double-sided, quad-density, 5-114 inch, removable disks are capable of storing one mega- byte of formatted data each.
