Drawing on its Telcordia, Bellcore
and Bell Labs heritage, Applied Communication Sciences excels at creating innovative technologies and services to solve the most difficult, complex information and communications problems.
* MAPS-ISDN application now supports 4ESS & Bellcore
The task of keeping the systems synchronized kept quite a few AT&T and Bellcore
Founded by two leading Bellcore
scientists, the company has been helping customers prove the integrity of their electronic records since 1994.
It was built in 1985 by Torcon for Bellcore
, the research group for the seven original Bell operating companies.
Mr Ahuja was previously president of Telcordia Technologies - formerly Bellcore
- the world's largest provider of operations support systems, network software and consulting and engineering services to the telecommunications industry, providing consulting services and communications software used by 80 per cent of the US telecoms network.
Conforming to Bellcore
and ETSI requirements, they are capable of accepting a range of input voltages from 36 to 75 Vdc.
These transceivers exhibit exceptionally low levels of jitter over the full Bellcore
operating temperature range of -40 degrees to +85 degrees C.
It also meets Bellcore
1217 specifications for telecom equipment.
The S/UNI-1x155 jitter performance meets all Bellcore
GR-253 intrinsic jitter, jitter tolerance, and jitter transfer specifications.
This Stratum 3E Clock meets or exceeds all Bellcore
GR-1244-CORE requirements, meaning it is able to deliver less than 10 ppb total frequency change in holdover mode for a period of 24 hours.
* A fully Bellcore
compatible GR303 family of interfaces allowing for direct connection to the leading manufacturers of Class 5 telephone switches, DMS 100, DMS 10, 5 ESS and soon-to-follow releases for the GTD 5 and EWSD type installations.
