Voice over IP (VoIP) is a dominant form of communication in the workplace. Internet telephone calls can originate from traditional phones via analog trunk gateways by either PCs using software or embedded devices such as IP Phones. Internet telephony integrates a variety of services provided by the current Internet and Public Switched Telephone Network (PSTN) infrastructure.

The DIV-140 Analog Trunk Gateway is the bridge between local PSTN phone lines and an Ethernet IP network. The result is a combination of phone and fax services that assimilate with your data network. The DIV-140 features four RJ-11 analog FXO ports for connecting to the local PSTN phone lines and one 10/100Base-TX connector for a local Ethernet network.

The DIV-140 Analog Trunk Gateway is an ideal solution for converging your business phone requirements to next generation communication services and can be used in a variety of possible solutions.

Solution A:
A solution for routing current phone systems over the Internet. This can be used for connecting phone systems for a company with many branches, or as toll-bypass for phone systems located in most Internet accessible locations in the world.

Solution B:
A solution for expanding your current phone system. It can be used to connect cost-effective Ethernet IP telephony devices, like an IP Phone, to most standard phone systems.

Solution C:
A solution for adding new technology to your current phone system. It can be the gateway for Wi-Fi Session Initiation Protocol (SIP) IP Phones or Hybrid Phones.

Solution D:
A solution for routing current phone systems to Internet Telephony Service Providers (ITSP), which give you low per minute or flat-rate phone services.

Solution E:
A solution to provide your SIP IP PBX access to local PSTN phone lines. It allows IP telephony products access to inbound 800 phone numbers, outbound 911 services, and back-up routes to ITSP.

The DIV-140 includes a Layer 3 IP TOS QoS engine, which prioritizes voice data packets to enable smoother voice quality. In addition, it also offers 802.1Q compliance for Layer 2 VLAN segmentation. Traffic management mechanisms improve call quality and reliability and can be tuned to fit your data network. The DIV-140 is hardened against network attacks with its built-in packet inspection engine. Access to its phone services is securely handled by SIP standard challenge-response authentication.

Lightweight and compact in design, the DIV-140 Analog Trunk Gateway is designed for any size business. With voice detection, echo cancellers, and a comfort noise generator (CNG), the DIV-140 delivers a high quality, cost-effective solution to any business IP network.
