Reliability Testing for Telcordia (Bellcore) Test Requirements:

Many products in the telecommunications industry are required to meet various Telcordia (Bellcore) Generic Requirement (GR) specifications to establish product quality and reliability. Several of these specifications require environmental/thermal testing and often refer to other MIL STD and EIA / TIA test specifications. CSZ offers a full line of test chambers capable of meeting these requirements. Our chambers simulate environmental conditions that these telecommunications products will be exposed to during the product’s use, transportation, and/or storage.

Listed below are a few common Telcordia test specifications that require the use of environmental testing. Outlined are the test conditions related to our test chambers along with the CSZ model we recommend to perform the test. For more information on Telecordia General Requirements or to purchase a copy of the full specification, visit Telcordia’s web site at www.telcordia.com.

Telcordia (Bellcore) Generic Requirement Description/Applicable Product
GR-49-CORE for Outdoor Telephone Network Interface Devices
GR-63-CORE for Network Equipment-Building System Requirements (NEBS): Physical Protection
GR-326-CORE for Single Mode Optical Connectors and Jumper Assemblies (Fiber Optics)
GR-468-CORE for Optoelectronic Devices Used in Telecommunications Equipment
GR-487-CORE for Electronic Equipment Cabinets (Enclosures)
GR-974-CORE for Telecommunications Line Protector Units (TLPUS)
GR-1209-CORE for Fiber Optic Branching Components
GR-1221-CORE for Passive Optical Components
The above list is not intended to be inclusive of all Telcordia Generic Requirements that require environmental testing. If you have a test requirement for other Telcordia specifications, contact us to see how we can meet your needs.

CSZ also provides ports of various sizes (circular, square and rectangular) for your cable routing needs. You simply specify your port location and fixture needs. Every Telcordia (Bellcore) specification referenced above requires testing at the low temperature of -40°C. Our new Tundra system can efficiently test your product down to the low temperature of -45°C and be included in any environmental chamber.
