It features a complete digital interface to other Vortex products using the digital expansion bus. The EF2201 interfaces telephone audio to the Vortex family of products and allows up to 8 callers to be added to the same conference by using 8 EF2201s. Telephony signals are communicated with Vortex devices over the digital "P-bus" channel of the EF Bus without the need for an analog input and output. The EF2201 can be controlled via RS-232, Vortex Expansion bus, and via the front panel controls. The EF2201 has audible ring indications, user configurable entry and exit tones, and controllable levels of DTMF and dialtone signals. The EF2201 settings are configured using the Conference Composer software and can be stored as user presets within the EF2201. The EF2201 connects directly to an analog (PSTN) telephone line, connecting an outside caller to your meeting. In addition to providing crystal-clear telephone audio to all participants, the EF2201 significantly reduces background noise coming in on the telephone line to keep unwanted sounds from interfering with your conference.

The equipment shall be connected to a socket-outlet that provides a protective earthing connection. North American Requirement CAUTION-To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. MOUNTING THE EF2201 The EF2201 can be mounted in a rack enclosure using four large screws (10-32x1/2") included with the unit. One EF2201 fits in a single rack space. Recommendation For Easy Access Instructions for Securing Power Supply to Back of EF2201 While not required, leave a single rack space in between the EF2201 and other units in your rack. This gives you easier access to the back panel. · · · · · Locate the cable clamp on the back panel of the EF2201 above the power connector. Remove the screw and thread the power cord through the cable clamp. Attach the cable clamp to the back panel of the EF2201 and tighten the screw. Align the clamp so that the power cable does not interfere with the connectors on the EF2201 back panel. Plug in the power supply. We recommend that you also Ty-wrap the power supply to the rack. The purpose of securing the power supply to the back panel is so that if the power supply were to drop, it would pull where the cord is attached with the cable clamp and not pull the plug out of the EF2201. Caution! Do not use any other power supply other than the one provided with this unit.
