Analog Trunk

Overview

The analog trunk protocols allow callers to enter tone only, numeric display, alphanumeric and voice pages. Analog trunks are supported within the Verizon Business network for incoming, outgoing, and two-way traffic and direct inward and outward dialing.

Benefits
 

• Two-way calling. The direct inward-outward dialing (DIOD) trunks offer inward and outward calling.
• One trunk group. Traffic studies are easier to evaluate in terms of traffic capacity/requirements.
• Direct station dialing. Incoming calls are automatically directed to the station’s user without attendant assistance. This feature reduces the requirement for attendant positions, reducing or eliminating attendant labor costs.
• Analog trunking. No additional equipment is needed to replace existing DID trunks.
