MERLIN LEGEND Communications System Release 6.1 Issue 1 Maintenance and Troubleshooting 555-661-140 August 1998 Page A-20 Other Security Hints It is strongly recommended that customers invest in security adjuncts, which typically use one-time passcode algorithms. These security adjuncts discourage hackers. Since a secure use of the Remote Access feature generally offers savings over credit-card calling, the break-even period can make the investment in security adjuncts worthwhile.
