4. A data cable having a plurality of twisted pair conductors, a cable covering, and an interior support comprising:
said interior support being unshielded and having:
a longitudinally extending central portion forming a portion of said support; a plurality of projections extending from said central portion;
each projection of said plurality of projections being adjacent to two other projections of said plurality of projections, said plurality of projections forming a plurality of adjacent projections;
an open space defined by each of said plurality of adjacent projections;
said cable covering contacting each projection; only one twisted pair conductor from said plurality of twisted pair conductors disposed in each open space.
5. The cable of claim 4 wherein each of said projections is a projection selected from a group consisting of a prong, a spline, and an arm.
6. The cable of claim 4 wherein said open space is an open space selected from a group consisting of a channel, a groove, a duct, and a passage.
7. A data cable having a plurality of twisted pair conductors, a cable covering, and an interior support comprising:
said interior support being unshielded and having:
a longitudinally extending central portion forming a portion of said support; a plurality of projections extending from said central portion;
each projection of said plurality of projections being adjacent to two other projections of said plurality of projections, said plurality of projections forming a plurality of adjacent projections;
an open space defined by each of said plurality of adjacent projections;

The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
What is claimed is:
1. A system for rescheduling material procurement according to altered demand, the system comprising:
a production planning module for scheduling production and generating production scheduling sheets; and
a procurement rescheduling module for rescheduling material procurement according to the production scheduling sheets, the procurement rescheduling module comprising:
a time span management submodule for managing procurement time spans for different materials,
a demand calculation submodule for calculating revised demand for materials in each procurement time span,
a delivery date calculation submodule for calculating delivery dates for materials procurement according to the production scheduling sheets, and
a material purchase order generating submodule for automatically generating material purchase orders.
2. The system as claimed in claim 1, further comprising a database that stores inventory data and bill of material data.
3. The system as claimed in claim 2, further comprising a material management module for managing inventory data and bill of material data stored in the database.
4. A method for rescheduling material procurement according to altered demand, the method comprising the following steps:
receiving a purchase order modification from a customer;
calculating a total demand for material for at least one preset procurement time span;
calculating a balance of material according to the total demand for material and supply of material;
determining at least one delivery date for material required for the at least one procurement time span; and
generating and sending out a material purchase order.
5. The method as claimed in claim 4, further comprising the step of:
rescheduling production and generating a production scheduling sheet according to the purchase order modification.
6. The method as claimed in claim 4, wherein there is a plurality of procurement time spans, and the procurement time spans vary according to the material required.
7. The method as claimed in claim 4, wherein the supply of material comprises material provided according to an original purchase order and available inventory.
8. A method of material procurement arrangement comprising:
receiving an initial product purchase order from a customer;
arranging an initial material purchase order for at least one preset procurement time span;
receiving a modified product order from the customer;
calculating a total demand for material for said time span;
calculating a balance of material according to the total demand for material and supply of material;
determining at least one delivery date for material required for said time span; and
generating and sending out a modified material purchase order.
