FeaturesSystem Features20 Strata DK Feature Description 5/99Amplified ConferenceOne or more customer-provided automatic gain, switched, two-way line amplifiers can beconnected to proprietary station ports in the system. The amplifiers are automatically activatedwhenever a user conferences two CO lines together. Up to two amplifiers can be connected on theDK40i and up to four amplifiers on DK424 systems.With Strata DK systems using Amplified Conference, there is negligible loss through the system,and the amplifier compensates for loss in volume over the public network. Any customer-supplied,two-way line amplifier that is FCC registered with Automatic Gain Control (AGC) should becompatible. The Reliance Electric model VFR 5050 has been successfully used.The amplifier increases signal strength between any two outside CO lines. If Tandem,Call-Forward External, or Direct Inward System Access (DISA) CO line connections are providedin the system, the CO line-to-CO line connection is amplified.Amplified connections are available on a first-come, first-served basis. On Strata DK systems,amplified conference is available to a standard telephone as well as digital or electronictelephones.Each amplifier requires two EKT station ports, and reduces the station capacity by two. The twoports supporting the amplifier must be designated ports on a PEKU card. One PEKU supports oneexternal amplifier.BenefitsEnables the external parties of a conference call to hear each other. Conference calls are shorterand more efficient, since time is not wasted repeating inaudible parts of the conversation. Shortercalls are cheaper calls. When conferees can hear clearly, they get accurate information.System AvailabilityStandard on Strata DK40i/DK424Unavailable on DK14
