2-1 Definitions General rules Apply the following rules for system engineering when arranging various Universal Equipment Modules (UEMs) within an SL- 1. Note: This document has been updated to include new naming conventions. Acronyms and abbreviations for the new names are identified in the text using parentheses.
2-2 Definitions through the I/O panels or EM1 filters. In addition, all vertical routing of the internal signal cables should be done on the right side of a column. The InterGroup UEM should be located at the top of a column and adjacent to the CE UEMs.
Definitions 2-3 Peripherals - One superloop (the equivalent of four regular loops) should serve two, four, six, or eight segments. A segment is one-fourth of the Intelligent Peripheral Equipment (IPE)(NT8D37AA/DC) shelf containing four slots.
2-4 Definitions Traffic distribution - The traffic distribution in the SL- 1 is illustrated in Figure 2-1. This illustration is valid when considering individual customer or system traffic.
Definitions 2-5 - Line=IT+OO+IOT+IOO where: Line = Line traffic in CCS IT = Incoming Terminating traffic in CCS. 00 = Originating Outgoing traffic in CCS IOT = Irma-Office Terminating traffic in CCS 1.
2-6 Definitions Equipment utilization Equipment is provided and maintained throughout the SL-1 location life at an 85% utilization level. Network loop traffic The recommended traffic level for a Netwo.
Definitions 2-7 Network loop assigning When assigning the loop number in systems equipped with two Network UEMs, the load should be distributed evenly across both UEMs. Loops should be assigned in the order shown in Table 2- 1. Record the loops used .
2-8 Definitions PE card distribution Using Worksheet M (provided at the end of this document), determine the total number of each type of PE cards (500, SLl, TRK, DTR, etc.) per PE UEM. Using Worksheets N and 0 (also provided at the end of this document), determine the number of Multiple Appearance Groups (MAG) assigned to each loop.
Definitions 2-9 Intelligent Peripheral Equipment (.IPE) card slot assigning Card slot priority Input messages from card slots 1 and 0 in each IPE module (card slot 0 in each EPE shelf) are directed to a high priority input buffer.. The input messages from the remaining slots on each -lPE module are directed to a low priority input buffer.
2-10 Definitions Attendant consoles - Attendant consoles should never be assigned to a high priority card slot. Too many high priority messages from attendant consoles assigned to these card slots can result in delays in output messages to attendant consoles, sets and trunks.
Definitions 2-11 Assigning cards - Procedure 2-1 Order for assigning cards 1 Assign cards requiring a card slot 1 assignment (high priority slot). 2 Assign cards for high-usage trunks, such as CO trunks. 3 Assign cards for low-usage trunks, such as paging and dictation.
2-12 Definitions Terminal number assigning Once the cards are assigned to the PE UEMs, the individual units on each card can be assigned. Use Worksheet Q (at the end of this document) to record the Terminal Number (TN) assignments. TN 0000 cannot be used on superloop 0.
Definitions 2-13 Equipment relief - When additional equipment is installed, assignments should be concentrated into the new loop or shelves until the first threshold study. At that time, the loop profile would be updated and a new loading plan developed.

32 System grounding - Single Point Ground This system does not, by design, require an isolated AC ground (IG) system (although local codes may require it). The system does require a single point ground (SPG) system. The SPG is needed because several conductors are used as returns.
System grounding 33 like ground system with local ground references like the LRE and ACIG coming together at a main ground window, while small systems tend to use a ground bar or plate for several purposes and it ends up taking on the name of it’s primary function.
34 System grounding Non-isolated ground topology In a non isolated system the AC equipment ground (ACEG) connects to the metal panel, and the associated conduit may also contact various structural metal. This ground alone is not adequate for the SL-1 system.

38 Operating power requirements System power calculation guidelines The SL- 1 system was designed so that there would be no restrictions as a result of power or thermal limitations. In other words, any card can go in any slot, and all modules can be filled to capacity with any (logically) valid combination of cards, with no engineering rules.
Operating power requirements 39 For calculations normally done in apparent or complex power (such as AC wire and panel size, UPS rating for AC reserve power, etc.), simply divide the total real power (in Watts) by the typical system power factor of 0.
