For use in exchange and campus areas, direct buried or installed in-duct.

Suitable for voice frequency use on all pairs and carrier frequency, both analog and digital, on a selected pair assignment basis.

For full pair utilization at carrier frequencies, a core-dividing screen is required. (See T1 cables.)

Specifications:

• Solid, annealed, bare copper conductors
• Conductor insulation is foamed polyolefin with a solid skin of the same material. Color-coded to telephone industry standards
• Insulated conductors are twisted into pairs of varying lengths of lay to minimize crosstalk
• Pairs are stranded into units (and super units, if required by pair count)
• The cable core is filled with a waterproofing compound and wrapped with a non-hygroscopic core tape
• Specifications permit six varieties of shielding, four of which are considered gopher-resistant
• A flooding compound is applied over the core and to all surfaces of the shield/armor to resist moisture entry and corrosion
• The cable is finished with a black polyethylene jacket which is sequentially printed with footage marker at regular intervals
