Excel, Inc. achieves CE mark for Euro-ISDN; Company also meets BABT DASS 2 compliance.

HYANNIS, Mass.--(BUSINESS WIRE)--June 25, 1996-Excel, Inc. announces its achievement of CE Mark for Euro-ISDN compliance for its LNX programmable switch. Euro-ISDN compliance is the standard that is established to achieve the CE Mark for ISDN communications in the European Community. Compliance testing was completed during May. Excel met all three Directives (described below) for Euro-ISDN, as well as the Deviations defining the French and German deltas.

Excel has also achieved Country-Specific Approvals for BABT compliance for DASS 2 as well as E1/75 Ohm standards operating on the LNX.

"This achievement marks another milestone in Excel's compliance program," said Bob Madonna, president of Excel. "Our North American compliance program includes NEBS, UL/CUL and FCC certifications for both the U.S. and Canada. European compliance is part of a corporate strategy to achieve compliance in our key markets worldwide. Our strategy is to continue achieving country-specific approvals based on the areas of the world where our systems are being deployed; the next test will be conducted with Australia." said Mr. Madonna.

To meet the requirements for Euro-ISDN and achieve CE Mark, companies must meet a set of Directives, including Low Voltage Directives for safety and electrical compliance, EMC Directives for emissions, and Telecommunications Terminal Equipment Directives which apply to "harmonized" standards where common technical requirements can be tested. CTR 4 applies to harmonized ISDN standards, while CTR 12 applies to harmonized E1/120 Ohm telecommunications standards. Excel met the requirements for both CTR 12 and CTR 4, which includes pan-European approval. The next category includes Deviations, of which there are only two for ISDN compliance: German and French; Excel completed compliance testing with both.

In addition to Euro-ISDN, Excel achieved the Country-Specific Approval for DASS 2 throught BABT.
