NEBS Deployment Site Requirements
NEBS Deployment Site Requirements
The NEBS GR-1089-CORE and GR-63-CORE compliance statements and requirements are listed in this
section. These statements only apply for deployments where NEBS compliance is mandated.
Warning
The intra-building port(s) (LAN, WAN, Serial, and T1 (NIM-xMFT-T1/E1 module)) of the equipment or
subassembly must use shielded intra-building cabling/wiring that is grounded at both ends. Statement 7003
Warning
The intra-building port(s) (LAN, WAN, Serial, and T1 (NIM-xMFT-T1/E1 module)) of the equipment or
subassembly is suitable for connection to intra-building or unexposed wiring or cabling only. The intra-building
port(s) of the equipment or subassembly must not be metallically connected to interfaces that connect to the
OSP or its wiring for more than 6 meters (approximately 20 feet). These interfaces are designed for use as
intra-building interfaces only (Type 2, 4, or 4a ports as described in GR-1089) and require isolation from the
exposed OSP cabling. The addition of Primary Protectors is not sufficient protection in order to connect these
interfaces metallically to an OSP wiring system. Statement 7005
Warning
The AC power ports have been evaluated for deployments where an external Surge Protective Device (SPD)
is utilized at the AC power service equipment (see definition in National Electric Code). Statement 7012
Warning
This product is designed for a Common Bonding Network (CBN) installation. Statement 7013
Warning
This product can be installed in network telecommunication facilities or locations where the National Electric
Code applies. Statement 8015 and 8016
Warning
The DC return connection to this system should remain isolated from the system frame and chassis (DC-I).
Statement 7016
The following instructions and requirements are mandated for the C1100TG series when the NIM-LTEA-EA
module is installed in a NEBS deployment utilizing cables connected to outdoor antennas:
• Additional surge protection is required if an outdoor antenna is being connected to the GPS connector
• Lightning protection must be mounted at the location where the antenna cable enters the building. The
• Surge arrestors should support DC-pass and suitable for the frequency range with low attenuation.

and/or the LTE TNC connectors. The Lightning Protector must be able to provide a low clamping voltage
(less than 600V).
primary lightning protection must be capable of conducting all potentially dangerous electrical energy
to PE (Protective Earth).
