Bandwidth means a distributor’s defined tolerance used to flag data for further scrutiny at the stage in the VEE process where a current reading is compared to a reading from an equivalent historical billing period. For example, a 30 percent bandwidth means a current reading that is either 30 percent lower or 30 percent higher than the measurement from an equivalent historical billing period will be identified by the VEE process as requiring further scrutiny and verification;
Tier 2 Support means the Esri Technical Support provided to the Tier 1 Help Desk when a Case cannot be resolved through Tier 1 Support.
Tier 3 Wire Centers are those Embarq Wire Centers that are not Tier 1 or Tier 2 Wire Centers.
Digital Signal Level 0 (DS-0 means the lowest-level signal in the time division multiplex digital hierarchy, and represents a voice-grade channel operating at either the 56 Kbps or 64 Kbps transmission bit rates. There are twenty-four (24) DS-0 channels in a DS-1.
Digital Signal Level 1 (DS-1 means the 1.544 Mbps first level signal in the time division multiplex hierarchy.
Tier 2 means the portion of the design- related information contained in the generic DCD that is approved but not certified by this appendix (Tier 2 information). Compli- ance with Tier 2 is required, but generic changes to and plant-specific departures from Tier 2 are governed by Section VIII of this appendix. Compliance with Tier 2 pro- vides a sufficient, but not the only accept- able, method for complying with Tier 1. Compliance methods differing from Tier 2 must satisfy the change process in Section VIII of this appendix. Regardless of these dif- ferences, an applicant or licensee must meet the requirement in Section III.B of this ap- pendix to reference Tier 2 when referencing Tier 1. Tier 2 information includes:
Tier 1 Help Desk means Customer's point of contact(s) to provide all Tier 1 Support within Customer's organization(s).
Digital Signal Level 3 (DS-3 means the 44.736 Mbps third level signal in the time division multiplex hierarchy.
Rated Voltage means the manufacturer’s design voltage at which the transmission system is designed to operate or such lower voltage at which the line is charged, for the time being, in consultation with Transmission System Users;
Switched Access Service means an offering of facilities for the purpose of the origination or termination of traffic from or to Exchange Service customer in a given area pursuant to a Switched Access tariff. Switched Access Services include: Feature Group A, Feature Group B, Feature Group D, 800 Series, and 900 access. Switched Access does not include traffic exchanged between LECs for purpose of local exchange interconnection.
Tier 1 Support means the Technical Support provided by the Tier 1 Help Desk.
Generator Maintenance Outage means the scheduled removal from service, in whole or in part, of a generating unit in order to perform necessary repairs on specific components of the facility, if removal of the facility meets the guidelines specified in the PJM Manuals.
Synchronous Optical Network (SONET) is an optical interface standard that allows inter-networking of transmission products from multiple vendors. The base rate is 51.84 Mbps (“OC-1/STS-1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.
Semi-annual (2/Year) sampling frequency means the sampling shall be done during the months of June and December, unless specifically identified otherwise.
Vapor balance system means a combination of pipes or hoses which create a closed system between the vapor spaces of an unloading tank and a receiving tank such that vapors displaced from the receiving tank are transferred to the tank being unloaded.
Custom Local Area Signaling Service Features (CLASS Features) means certain Common Channel Signaling based features available to End Users, including: Automatic Call Back; Call Trace; Distinctive Ringing/Call Waiting; Selective Call Forward; and Selective Call Rejection.
Digital Signal Level 0 or "DS0" means the 64 Kbps zero-level signal in the time-division multiplex hierarchy.
Basic generation service or "BGS" means electric generation
Switched Access Detail Usage Data means a category 1101xx record as defined in the EMI iconectiv Practice BR 010-200-010.
Tier 2 Wire Centers means those CenturyLink Wire Centers that are not Tier 1 Wire Centers, but contain at least three (3) Fiber-based Collocators, at least twenty-four thousand (24,000) Business Lines, or both. Once a Wire Center is determined to be a Tier 2 Wire Center, that Wire Center is not subject to later reclassification as a Tier 3 Wire Center.
Synchronous Optical Network (SONET means the optical interface standard that allows inter-networking of transmission products from multiple vendors. The base rate is 51.84 Mbps (“OC 1/STS 1”) and higher rates are direct multiples of the base rate, up to 13.22 Gbps.
Semi-annual (2/Year) sampling frequency means the sampling shall be done during the months of June and December, unless specifically identified otherwise.
Retail Service and Maintenance Sector Means the service and maintenance of retail facilities which includes financial institutions, retail businesses, schools and hospitals but does not include commercial premises as defined.
Digital Signal Level 3 or "DS3" means the 44.736 Mbps third-level signal in the time-division multiplex hierarchy. In the time-division multiplexing hierarchy of the telephone network, DS3 is defined as the third level of multiplexing.
Generator Planned Outage means the scheduled removal from service, in whole or in part, of a generating unit for inspection, maintenance or repair with the approval of the Office of the Interconnection in accordance with the PJM Manuals.
Digital Signal Level means one of several transmission rates in the time-division multiplex hierarchy.
