Network Equipment Building System
(NEBS) The Point System
has been built to meet NEBS (Network Equipment Building System)
requirements. NEBS is a major test of quality that is extremely valuable
for any organization supplying or purchasing network equipment. A product
that is NEBS certified has passed a suite of tests ensuring that the
product will: - Operate reliably
and be serviceable
- Not negatively
affect other service providing equipment
- Operate properly
in adverse environmental conditions
- Not cause harm
to the environment or personnel
NEBS criteria are designed to accomplish the following: - Ensure equipment
compatibility with the telephone industry's electrical
environment
- Simplify
equipment planning and installation
- Protect
telecommunications equipment from service outages caused by
incompatible equipment
- Prevent
interference to licensed radio transmitters and other close proximity
telecommunications equipment
- Minimize the
risk of fires to telecommunications equipment
- Ensure equipment
operation under the range of temperature, humidity, vibration, and
airborne contamination present in telecommunications
locations
- Ensure equipment
and service survivability in the event of earthquake
- Protect
personnel from injury
| There
are three levels of NEBS approvals. Transition Networks's Point
System meets the NEBS Level 3 requirements: | | | Level
1: | - Minimum
environmental compatibility
- Applications:
Prototype equipment, equipment used for non-vital services
| Level
2: | - Assures limited
equipment operability in controlled or normal environment
- Applications:
equipment used in data centers or failure-tolerant services
| Level
3: | - Assures maximum
equipment operability
- Applications:
critical network equipment (e.g. switches, transport products, power
systems)

| | CISPR Class
B (back to top) | CISPR is the
acronym standing for the Comité International Spécial des
Perturbations Radioélectriques (International Special Committee on
Radio Interference) of IEC.
CISPR Class B is an
international standard that covers the amount of interference from
electromagnetic signals allowed from electronics in homes and
multi-tenant dwellings. It is more stringent than the Class A
certifications required of most electronics. Point System products have
been tested to meet all requirements of Class A. Transition's
18-slot Point System chassis (CPSMC1800-200) is also FCC Class B and
CISPR Class B compliant (residential). In order to
maintain Class B rating all devices in the system must also be Class B
rated. |
| | FCC Class A
& B (back to top) | FCC (Federal
Communications Commission) is the regulatory body that establishes
standards for interstate telecommunication services in the United States.
Part of the FCC's responsibilities is to establish standards for
radiated emissions for a variety of operating environments such as
residential and commercial structures. FCC Class A describes requirements
for radiated emissions in commercial structures while FCC Class B
describes emissions requirements for residential applications. In addition to
being FCC & CISPR Class A compliant (commercial use)
Transition's 18-slot Point System chassis (CPSMC1800-200) is also
FCC Class B and CISPR Class B compliant (residential). |
