July 19 (Reuters) - JPMorgan Chase ( JPM ) said it is

working to restore service to automated teller machines (ATMs)

affected by a global digital outage while a majority of its ATMs

are operating normally, according to an emailed statement on

Friday.

The largest U.S. bank declined to comment on how many of its

ATMs were offline. It has 16,000 ATMs across the U.S. and 4,800

branches.

Financial firms were among many snarled by a global digital

outage on Friday that caused hourslong disruptions to computer

systems at hundreds of companies.

Bank teller stations were not working at at least two

JPMorgan ( JPM ) branches in New York, according to employees at

different locations who declined to be identified discussing the

outage. Both employees said they were unsure when their

computers would be restored.

Branches have remained open, and at the sites affected by

the outages, customers were able to access banking services by

making manual transactions with tellers or using ATMs, a source

familiar with the situation said.
