2、using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or authority to issue an inte

Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised o

Purchasers of American National Standards may receive current information on all standards by calling or writing the American

Transport category equipment may be located in a central office, co-location area, outside plant cabinet,
6、controlled environment vault, customer located telecommunications closet, customer located indoor cabinet, or any similar location. In all cases, Transport category equipment is owned by the carrier. Examples of Transport category equipment include, but are not limited to: SONET/SDH ADMs, MSPP, and
7、similar equipment. “OTN” (Optical Transport Network) equipment. Digital Cross Connect Systems (DCS). ROADM/WDM and similar equipment. Video transport equipment. Storage area networking equipment. Free space optics. Point-to-point wireless transport (e.g., Microwave). 4.2 Optical Access Equipment The
8、 optical access network refers to the network between the local exchange and the subscriber with point-to-point interfaces and point-to-multipoint interfaces (e.g., G.PON), which are adapted to traditional services such as the voice, leased lines, and data transmission. Examples of Access category e
9、quipment include, but are not limited to: ONT Optical Network Terminal. OLT Optical Line Terminal. DPU Distribution Point Unit. 5 Metric Definition 5.1 Preamble Todays transport and optical access products are multi-service. A single chassis can simultaneously support a variety of circuit packs addr
10、essing everything from Layer 0 photonic/wavelength switching, Layer 1 time division multiplexed (TDM) switching, Layer 2 packet processing, and more. In cases when a system consists of a chassis or shelf with multiple slots that can be equipped with a variety of modules, a system can be configured i
11、n tens or even hundreds of ways. Consequently, there could be as many ATIS-0600015.02.2016 5 TEER reports for a given chassis-based system as there are ways of configuring it. Furthermore, in order to provide flexibility and scalability, some systems can be extended by adding shelves or external per
12、ipherals. Therefore, this standard will not define a single TEER, but rather it will define a method for computing the ratio of the raw data rate (in Mbps) to power consumption (in Watts) for any desired configuration. In this manner, for a given transport and optical access networking scenario, mul
13、tiple products or solutions can be evaluated. The metric can be used to evaluate the many possible configurations for one product as well as to compare multiple products. The higher the TEER, the more efficient the solution. This standard also shows how the methodology can be extended to the calcula
14、tion of the TEER of an entire network configuration. 5.2 Transport however, if the application requires unidirectional operation, the standard data rate shall be halved. If line or facility protection scheme such as 1+1 is requested, the data rates of both physical interfaces shall be included in th
15、e summation (in such traffic protection schemes, there are multiple physical interfaces carrying data and the data rate of each is included in the calculation). For asymmetrical interfaces, the standard data rate shall be half the sum of the transmit and receive rates. If an equipment redundancy sch
16、eme is requested where one physical line or facility is associated with more than one module (such as 1:N equipment protection), only the data on the shared physical line or facility should be counted (in such equipment protection schemes, one or more physical interfaces share two or more modules vi
17、a a splitter/coupler/selector; however, the power consumed by the working and protection modules needs to be included in the power calculation). If a module supports more interfaces and/or data rates higher than specified by the application description, these cannot be included in the summation. How
18、ever, additional TEERs could be voluntarily computed assuming that a module is more fully utilized for comparison. 5.2.5 Module Power, P The power of all required common equipment is to be included in the calculation along with the service interface, pluggable modules, and any auxiliary or periphera
19、l equipment required to satisfy the requested configuration defined in the application description. The application description should specify whether optional redundant equipment is required for the application. If a module supports more interfaces than specified in the application description and
20、such a module has the ability to conserve power when the unused (unequipped) interfaces are disabled, it is possible to use the more accurate input power number for the partially-utilized module. Given that it is not practical to obtain test data for all possible configurations of a system, an equip
21、ment supplier shall comply to the general test method and environmental conditions specified in ATIS-0600015 to build a database of module-level power that can be used to calculate the typical power of any possible configuration. It is understood that an application may call for one or more modules
22、still in development that may not have certified energy consumption data. A declared TEER response can include an engineering estimate for such modules provided this is clearly indicated in the report. Though a TEER report should address a requested application description in its entirety, it may no
23、t be possible to specify a practical solution to address it. Occasionally, a slight modification can be proposed that is technically equivalent (such as substituting four OC-48 inter-shelf links with one OC-192 link). The TEER report shall include a list of any deviations from the original applicati
24、on description. ATIS-0600015.02.2016 9 6 Test Procedure 6.1 Equipment Configuration The test methodology and conditions used to measure the equipment input power used as part the TEER calculation are addressed in ATIS-0600015. 6.2 Traffic Generation/Operational Conditions The operational conditions
25、used to independently measure the equipment input power used as part of the TEER calculation are addressed in ATIS-0600015. The TEER calculation requires that power measurements be obtained at three configuration data utilization levels: 0%, 50%, and 100%. PCERT_0is the measured configuration power
26、at data utilization of 0%, noted as D0. PCERT_50is the measured configuration power at data utilization of 50%, noted as D50. PCERT_100is the measured configuration power at data utilization of 100%, noted as D100. The PCERT_100 value is obtained when the system under test has all interfaces fully e
27、xercised carrying 100% port line rate data using a test set(s) that generate appropriate test patterns. The practice of daisy-chaining, cascading, or looping back ports in order to ensure that all interfaces are fully exercised with the test traffic stream(s) is acceptable. For Ethernet ports, the t
28、raffic mix shall follow the simple IMIX profile at 100% of the port bandwidth. The PCERT_50 value is obtained when the system under test is left as in the PCERT_100 configuration and the test set(s) are reconfigured to generate traffic at 50% of the ports line rate. For Ethernet ports, the traffic m
29、ix shall follow the simple IMIX profile at 50% of the port bandwidth. For non-Ethernet mapped ports (such as OC-N/STM-N, DS-3, DS-1, etc. as listed in Table A.1 and OTN mappings as listed in Table A.2), the test traffic shall be left at the protocol-defined line rate on 50% of the available ports, w
30、hile the remaining 50% of ports shall be left unloaded (i.e., with link management traffic but no data traffic). During this test, the equipment under test may experience alarms on the unloaded ports, which is acceptable. The PCERT_0value is obtained when the equipment under test is left as in the P
31、CERT_100 configuration and the test set(s) are reconfigured to generate traffic at 0% of each ports line rate. The equipment under test may experience alarms during this test, which is acceptable.
