Telecommunications facilities covered

This above-baseline standard applies to central offices and similar-type facilities in public telecommunications networks in which a special measure of resistance to damage from high-altitude electromagnetic pulse (HEMP) is desired. It describes electrical protection measures that extend beyond the baseline-level measures against the normally encountered electromagnetic threats included in T1.308-1996 (R2002) and T1.313-2003. The measures of this standard are intended for telecommunications facilities that contain electronic communications equipment, including switching centers, central offices, signal transfer points, head-ends, Electronic Equipment Enclosures (EEE), routers, and any other subsystem upon which the call process is dependent.

Application of protection measures

This standard is intended to provide practical and cost-effective electrical/electromagnetic protection measures that will impart a basic level of protection against HEMP for central offices and similar type facilities of public telecommunications networks (PTN). It presents a background of generalized measures to be applied to a specific site. The protection measures of this above-baseline standard shall be negotiated with each individual service provider (local exchange carrier, interexchange carrier, etc.) as each situation arises.

Measures not covered

This standard does not cover the specialized and comprehensive measures that would be needed for near- absolute immunity to HEMP on special-purpose, hardened telecommunications routes. Detailed site-specific measures are beyond the scope of this standard and are subject to negotiation between user and supplier. The measures described in this standard apply at the facility level, and do not provide techniques for the protection of specific network equipment or components.
