Configurations: CONFERENCING

This configuration provides 24-caller conference switching with spectacular ease and sound clarity. System operation:

• The EA24 interfaces with the telephone network in ISDN or T-1 mode for inbound calls
• The TGD24 detects and generates MF or DTMF (touchtone) digits to route calls
• The SS96 is the switch that connects the calling party to a particular conference
• The SB96 provides multiple-party call capabilities
  --up to 24 members in two-way or listen-only mode
• The MSI interfaces to local operators or monitors
• The D/240SC provides 24 ports for menus/prompts

DEBIT CARD

This configuration provides either ISDN or standard T-1 inputs and outputs, call tone detection, dialing, and room for expansion. This system can be used in a variety of ways:

• Calling card verification
• Least cost routing
• ISDN conversion
• ANI checking
• Concentrator for several different long distance carriers

CALL CENTER

This configuration provides either 96 ISDN or standard T-1 channel inputs and outputs. 48 call analysis resources for high-volume outbound calling, and 48 operator extensions. Perfect for:

• Telemarketing applications
• Inbound 800 or 900 promotions
• Automated or operator-assisted dialing
• Predictive dialing

INTERNATIONAL CALLBACK This configuration provides complete network connections and call switching control for international callback. System operation:

• The DID/120 board receives the international customer's callback signal request
• The EA24 interfaces with the telephone network to complete the callback to the proper location
• The SS96 provides switching capability
• The SS192 generates the callback
• The TGD24 detects incoming, and produces outgoing MF or DTMF routing digits or custom tones and allows voice path control gain
