Common use of Categories of Loops Clause in Contracts

Categories of Loops. There are six general categories of loops: 4.2.1 2-wire analog voice grade" loops will support analog transmission of 300-3000 Hz, repeat loop start or ground start seizure and disconnect in one direction (toward the end office switch), and repeat ringing in the other direction (toward the end user). This loop is commonly used for local dial tone service; 4.2.2 4-wire analog voice grade" loops conform to the characteristics of a 2-wire voice grade loop and, in addition, can support the simultaneous independent transmission of information in both directions; 4.2.3 2-wire digital" loops will support industry standard specifications for digital transmission. Special provisioning (removal of bridge taps and/or load coils) will be required to conform to these industry standards. The price for 2-wire digital loops shall be the price for the basic 2-wire loop plus the loop facility NRC to recover the cost of the special provisioning. 4.2.4 4-wire digital" loops will support industry standard specifications for digital transmission. Special provisioning (removal of bridge taps and/or load coils) will be required to conform to these industry standards. The price for 4-wire digital loops shall be the price for the basic 4-wire loop plus the loop facility NRC to recover the cost of the special provisioning. 4.2.5 DS-1" loops 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 span line repeaters where required, office terminating repeaters, and DSX cross connects. Prices for DS-1 grade loops are the prices set forth in the appropriate GTE intrastate special access tariff. 4.2.6 DS-3" loops 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.
