Page 21: What Is The Switch Performance Monitoring System
What is the switch performance monitoring system? The switch performance monitoring system (SPMS) is a series of index values that describe how well the switch is operating. Performance results are displayed in a report. Index values are computed from switch-generated operational measurements (OM) on a daily and customer-defined monthly basis.
Page 22 1-2 What is the switch performance monitoring system? SPMS provides a medium-term review comprising detailed as well as summary level index values. This makes deviations from desired results easy to trace back to their origin. SPMS produces performance indices covering all areas of switch operation. Each index is standardized so that an index result of 100 indicates perfect performance an index result of 95 indicates average performance as observed over a...
Page 23 What is the switch performance monitoring system? 1-3 In many cases, events and conditions flagged by SPMS will have already been acted upon, or may reflect the results of maintenance actions. It is important to keep a record of all maintenance actions affecting the operation of the switch, from parameter changes through card changes.

Page 47: The Indexing Hierarchy
The indexing hierarchy SPMS generates approximately 300 indices, covering all aspects of switch operation. This is too much information to handle all at once. The indices are therefore arranged in a hierarchy, or “tree.” Indices at higher levels in the tree summarize the performance that is described in detail at lower levels.
Page 48: Spms Structure For Dms-100
3-2 The indexing hierarchy error counts, fault counts, or outage durations for the various switch components. The provisionable resources index (PROVRES) summarizes the performance of traffic provisionable resources for both hardware and software within the switch. Most of its basic indices track rates of overflow or blocking.

Page 65: How To Interpret Spms Reports
How to interpret SPMS reports SPMS indices has been calibrated using OM data from a large number of switches under normal working conditions. Day-to-day fluctuations in the indices of a few percent is normal, and not a cause for concern. If large variations in values do occur, they should be immediately investigated.
Page 66: Daily And Report Month Results
How to interpret SPMS reports 4-2 with successive days (if applicable) printed in separate columns across the page. The two final results shown for each index are the report month averages for the current month to date and the previous complete month (these are the only results shown if 0 days are requested).
Page 67: Demand Reports
How to interpret SPMS reports 4-3 At 23:50 each evening, under normal circumstances, the following events take place: SPMS swaps accumulating registers so that OMs from midnight onwards are added into a new set (which has previously been initialized to zeros). The old set is available for further calculations. SPMS completes the work needed prior to index calculation by acquiring various equipment counts needed as normalization factors.
Page 68: Operation In Abnormal Circumstances
How to interpret SPMS reports 4-4 shows total call volume for each day and flags those days on which reload restarts or reboots caused loss of data. Operation in abnormal circumstances Warm and cold restarts during the day interfere to some extent with the OM transfer process.
Page 69: Date Changes
How to interpret SPMS reports 4-5 what is happening with the journal file subsystem, not on the time of the restart itself. At times other than the first calculation after a reboot or reload restart, no check of the status of the journal file is made. If the journal file subsystem is not operating on any particular day, that day’s results are vulnerable to loss if a reboot occurs.
Page 71: Spms Service Index Descriptions
SPMS SERVICE index descriptions The following chapter provides index descriptions for the SERVICE branch of SPMS. The service index (SERVICE) summarizes switch performance as seen by the users of the switch. The high-level SERVICE index has two main branches, the maintenance service index (MTCESERV) and the provisioning service (PROVSERV) index.

Page 389: How Spms Index Values Are Calculated
How SPMS index values are calculated SPMS calculates switch performance by using two kinds of index: basic and aggregate. Basic indices A basic index consists of an operational measurement (OM) and a weighting factor. The factor is a calculation that uses constants derived from field results for a broad sample of offices so that index results are relative to this sample.
Page 390 9-2 How SPMS index values are calculated The value R is converted into an index with the help of a curve defined by five points. The curve consists of straight line segments joining these points. The points are as follows in table 9-1 and the curve in figure 9-1. Note: The SPMS R95 and R80 values may be changed at any BCS to represent the correct network performance as seen in the field.

How SPMS index values are calculated 9-3 Figure 9-1xxx Curve of R values SPMS index corresponding to R 2xR80 4xR80 Scaled Normalized Ratio Calculating aggregate indices Aggregate indices are summaries of their component basic indices. SPMS output gives the relative weight that is applied to each basic index under the heading WT.
Page 392 9-4 How SPMS index values are calculated The weighted average is a fraction. The top of the fraction is equal to the sum of the basic index values multiplied by their weights. The bottom of the fraction is simply the sum of the weights alone. In calculating an aggregate index, any basic index is ignored if it displays an NA instead of a numerical value.
Page 393: List Of Terms
10-1 List of terms AOSS See auxiliary operator services system. auxiliary operator services system (AOSS) A service-related system in which operators provide subscribers with such services as directory assistance (local and long distance) and call intercept. CCS7 See Common Channel Signaling No. 7. Common Channel Signaling No.
Page 394 10-2 List of terms failure rate The rate per working unit per unit time at which persistent malfunctions of equipment occur. Failure rate is the reciprocal of mean time between failures (MTBF). integrated services line module (ISLM) A line concentrating module that supports ISDN line cards. The ISLM works in association with the ISDN access controller.
Page 395 List of terms 10-3 link peripheral processor (LPP) The DMS SuperNode equipment frame for DMS-STP that contains two types of peripheral modules: a LIM and an LIU. For DMS-STP applications, CCS7 link interface units 7 (LIU7) are used in the LPP. See link interface unit.
Page 396 10-4 List of terms signaling connection control part (SCCP) A level of CCS7 layered protocol. It supports advanced services such as E800/SSP service and the Automatic Calling Card Service feature. The main functions of the SCCP include the transfer of signaling units with or without the use of a logical signaling connection and the provisioning of flexible global title translations for different applications.
Page 397 List of terms 10-5 total incoming attempts The total number of call attempts on the office incoming from trunks or operator positions, from the point of view of the central controller (CC). This is the sum of: OFZ NIN (with NIN2) TOPSTRAF TOPSNIN (with TOPSNIN2) minus TOPSCAN in TOPS offices...
