FRANKFURT (dpa-AFX Broker) - Shares in Adtran Holding recovered somewhat from their recent slide on Tuesday. The papers of the parent of telecom equipment maker Adtran Networks (formerly Adva Optical) gained more than 6 percent, but had also recently slumped more than 15 percent from their October high.

Operationally, however, Adtran was not convincing in the third quarter. In August, the holding company had already indicated that sales were likely to be up to one fifth below average analyst expectations - even this figure has now been missed./ag/tih
