Common use of Categories of Loop UNEs Provisioned Over Copper Loops Clause in Contracts

Categories of Loop UNEs Provisioned Over Copper Loops. There are six categories of unbundled loop UNEs that are provisioned over Copper Loops: (a) 2-Wire Analog Loop is a voice grade transmission facility that is suitable for transporting analog voice signals between approximately 300-3000 Hz, with loss not to exceed 8.5 db. A 2-wire analog loop may include load coils, bridge taps, etc. This facility may also include carrier derived facility components (i.e. pair gain applications, loop concentrators/multiplexers). This type of unbundled loop is commonly used for local exchange services. CenturyTel does not guarantee data modem speeds on a 2-wire analog loop. In addition, CenturyTel does not guarantee CLASS features will perform properly on a 2-wire analog loop provisioned over subscriber analog carrier. Rates for the loop, inclusive of the NID, are reflected in Appendix D along with associated non- recurring charges. (b) 4-wire Analog Loop conforms to the characteristics of a 2-wire voice grade loop and, in addition, can support simultaneous independent transmission in both directions. CenturyTel does not guarantee data modem speeds on a 4-wire analog loop. In addition, CenturyTel does not guarantee CLASS features will perform properly on a 4-wire analog loop provisioned over subscriber analog carrier. Rates for the loop, inclusive of the NID, are reflected in Appendix D along with associated non- recurring charges. (c) 2-Wire Digital Loop is a transmission facility capable of transporting digital signals up to 160 kpbs, with no greater loss than 38 db. end-to-end, measured at 40 kHz without midspan repeaters. Dependent upon loop make-up and length, midspan repeaters may be required, in which case loss will be no greater than 76 db. at 40 kHz (ISDN-BRI). In addition, 2- wire digital loops, dependent on loop make-up, may be configured to support Enhanced Copper Technologies (ECTs), such as ADSL. When utilizing ADSL technology, CD is responsible for limiting the Power Spectral Density (PSD) of the signal to the levels specified in Clause 6.13 of ANSI T1.413 ADSL Standards. These loops will be provisioned without load coils or bridged taps. A 2-wire digital loop is not available for ECTs where CenturyTel has provisioned its local network utilizing Digital Loop Carriers (DLCs). Also, CenturyTel does not provide the electronics required for ECTs provisioned via 2- wire Digital Loops. Rates for the loop, inclusive of the NID, are reflected in Appendix D along with associated non-recurring charges. (d) 4-Wire Digital Loop is a transmission facility that is suitable for the transport of digital signals at rates up to 1.544 MBPS. Dependent on loop length, this facility may require midspan repeaters. When a 4-wire digital loop is used by CD to provision HDSL technology, the insertion loss, measured between 100W termination at 200 kHz. should be less than 34 dB. The DC resistance of a single wire pair should not exceed 1100 ohms. These loops will be provisioned without load coils or bridge taps. A 4-wire digital loop is not available for ECTs where CenturyTel has provisioned its local network utilizing Digital Line Concentrators (DLCs). Also, CenturyTel does not provide the electronics required for ECTs provisioned via 4- wire Digital Loops. Rates for the loop, inclusive of the NID, are reflected in Appendix D along with associated non-recurring charges. (e) DS-1 loop UNEs will support a digital transmission rate of 1. 544 Mbps. The DS-1 loop will have no bridge taps or load coils and will employ special line treatment. DS-1 loops will include midspan line repeaters where required, office terminating repeaters, and DSX cross connects. Rates are as reflected in Appendix D, including non-recurring charges. (f) DS-3 loop UNEs will support the transmission of isochronous bipolar serial data at a rate of 44.736 Mbps. This DS-3 type of loop provides the equivalent of 28 DS-1 channels and shall include the electronics at either end. Rates are as reflected in Appendix D, including non-recurring charges.
