FOLSOM, Calif., Aug. 4 /PRNewswire/ -- Orckit Communications Ltd.
(Nasdaq: ORCTF) will introduce a new feature of their ORvision ADSL modem which can deliver ADSL service and two telephone lines simultaneously on a single copper pair wire line. This feature enables a Digital Added Main Line (DAML) system to be shared on the same copper pair line as an ADSL modem by allowing the DAML and ADSL signals to coexist simultaneously.
Orckit's DAML splitter provides a solution for the growing demand for second residential or SOHO phone lines created by the popularity of the Internet, home fax machines and teenager lines. The solution will be tested next month in conjunction with two leading DAML manufacturers: Raychem of Menlo Park, CA (www.raychem.com) and Charles Industries of Rolling Meadows, IL (www.chasind.com).
While DAML equipment has become a common method for enabling two telephone lines to be carried over a single copper pair, DAML systems prohibit deployment of any xDSL based service on the same line. With almost 10 percent of some regions of the U.S. using DAML, Orckit has developed the ideal solution to this problem. Last year, local phone companies reported that the percentage of homes with second lines increased significantly. The high cost for installation and wiring of second lines which required a new dedicated copper pair has found many local exchange carriers increasingly deploying DAML
to achieve cost efficient added second lines. "For telephone companies to move beyond xDSL trials, some practical operational problems needed to be solved," said Orckit's Vice President of Business Development, Nigel Cole. "The second line problem has grown into a key issue for carriers who are planning to deploy xDSL based services. Our solution not only overcomes the problem, but requires minimal impact on operational processes and enables continued use of these systems."
ADSL, the acronym for Asymmetric Digital Subscriber Line, is a
transmission technique that allows multi-megabit data transfer on regular telephone copper wires. That allows telecom operators to offer high speed data services to their customers without incurring a costly infrastructure investment. |
