Single Access Serving System (SASS) (anonymous) PROCESS DOCUMENTATION Santa Ana, April 8, 1997 SUBJECT Single Access Serving System (SASS). REASON FOR ISSUANCE This document will provide an EM Communication Technician with installation procedures for the Single Access Serving System (SASS) SWITCH TYPES AFFECTED 5ESS, DMS100 and 1AESS GENERIC/BCS REQUIRED None WORK FUNCTIONS AFFECTED Local Field Operations (LFO) EM Communication Technicians EFFECTIVE / CRITICAL DATES Effective immediately. TRACKING CODE Baseline QUESTIONS Questions regarding this document may be directed to Michele Baker at (714) 430-6640 GENERAL INFORMATION SASS is a transmission conditioning unit, a printed wiring card that employs a microprocessor control of test functions and provides voice prompting. The card is installed in an MFT bay and connected to the switch through an outgoing trunk. A dedicated POTS line is required for the ringback feature. This Single Serving Access System will allow both outside field technicians as well as LFO technicians the ability to perform multiple test functions using one access number. The Unit Test Features are: - ANI - Single Tone Generation - Three Tone slope - Ten Tone Slope - Full Tone Sweep - Caller ID Transmission - Data Sweep - Quiet Termination - Keypad Test CENTRAL OFFICE (CO) REQUIREMENTS 1. An MFT slot 2. An outgoing trunk OR A D4 port equipped with a DPT Channel Unit. 3. A new Trunk Group assignment will be established 4. The SASS Access Number wil need to be route indexed to the trunk or port assigned. 5. Assignment and cross connect to a POTS line for ringback capabilities. CENTRAL OFFICE (CO) PROCESS (1) Wiring the Circuit 1. You will receive two service orders for your SASS circuit. One for the design itself (se word) and one for the POTS line (1ML) associated with it. The POTS order will consist of only an OE assignment used for ringback capabilities. NOTE 1) The design portion of your order will resemble a DID circuit. NOTE 2) Every effort will be made to use a digital trunk assignment, however, if none are available, an analog trunk will be used in its place. NOTE 3) Make sure the channel unit used in the circuit is a D4CD200 (terminating). CENTRAL OFFICE (CO) PROCESS (2) Installing and Optioning The Channel Unit Install the SASS Unit into the designated MFT slot. Once the plug-in has been installed it should be optioned according to the manufacturers instructions on the card. CENTRAL OFFICE (CO) PROCESS (3) Initial Power-Up Verification Once the SASS unit is installed and optioned the Initial Power-up verification must be performed at the unit itself. CENTRAL OFFICE (CO) PROCESS (4) Procedure for Setting Transmission Levels Once the SASS unit has passed the Initial Power-up verification the Transmission Levels must be set for the unit. The following is the procedure for setting transmission levels on a newly installed SASS Unit. This function must be performed at the mainframe to any pair assigned to an OE in the respective switch in which the SASS unit was installed. The pair must be open and the reading taken toward the line card. STEP ACTION 1 At the mainframe, remove the coils from any working pair assigned to an OE in the respective switch. 2 Draw dial tone on the OE side of the open and dial the SASS access number. 3 Enter the SASS Security Code after the number announcement. The default Security Code is 222-2222. 4 Press 3 to Read or Change Prefixes 5 Press 5 to Generate Test Tone. 6 Enter * to Generate System Tone 7 Measure Tone with a transmission measurement test set. Should measure a level of 0dbBRNC. NOTE 1) Adjustments may be made by; entering a 6 to increase level by 0.1 dB each time the 6 is depressed, or entering 7 to decrease the level by 0.1 dB each time the 7 is depressed. 8 When you have completed setting the db levels, hangup to terminate the call. 9 A test must be performed on least three (3) prefixes to determine whether the db levels were set correctly in all prefixes.. A deviation of + or -1/2 db is acceptable. If tests reveal any variance greater than + or -1/2 db, you must repeat the procedure for Setting Tranmission Levels for every prefix. CENTRAL OFFICE (CO) PROCESS (5) Testing The Newly Installed SASS Unit When the SASS installation is complete, call the Test System Health Group to test the newly installed unit. They will in turn close the order out with OCS. CENTRAL OFFICE (CO) PROCESS (6) Troubleshooting A Newly Installed SASS Unit When the SASS installation is complete, the Initial Power-up verification has been performed, the transmission levels have been set and your circuit is still not turned up, try the following troubleshooting procedures.
