QWhat does the Motorola VT2142 Voice Gateway do?

AThe VT2142 Voice Gateway is a stand-alone media terminal adapter (S-MTA) containing a home router:

•

•

•

As an S-MTA, it converts analog voice signals to and from a standard telephone to digital data that can be transmitted through a broadband connection across the Internet. It provides an alternate means to make voice calls.

Its built-in router provides full network connectivity, a firewall, and VPN passthrough.

VT2142 prioritizes voice calls to enable simultaneous voice and data communication with no loss of voice call quality. For a description of the VT2142 features, see “Overview” on page 1.

QWill the VT2142 Voice Gateway work with a cable modem or DSL modem?

AYes. The VT2142 Voice Gateway supports DHCP, which is specified for DOCSIS® cable modems, and PPPoE, which is used by most DSL providers.

QCan I operate a virtual private network (VPN) application behind the VT2142?

AYes. The VT2142 Voice Gateway supports IPSec and PPTP, the most common VPN protocols.

QCan I play online games through my VT2142?

ABy default, the voice gateway blocks all unsolicited messages to the computer or local network as a standard security measure. However, for online games that require some unsolicited messages to be transmitted through the voice gateway, you can specify ports and IP addresses on which to allow unsolicited messages. The VT2142 enables you to set up virtual servers or a DMZ.

QHow do I configure the VT2142?

AMost people can send and receive calls immediately after completing Installation! You can configure your home or office network through a GUI using a connected computer configured to obtain its IP address using DHCP. Or, you can configure the computer statically to 192.168.15.xxx (xxx is from 2 to 254), subnet mask 255.255.255.0, and default gateway 192.168.15.1.

QWhat is included with the built-in router?

AThe VT2142 supports a firewall, RIP, port triggers, advanced ALGs such as RSVP, POP3, SNMP, and streaming media. No separate routers are needed. To connect more than one computer or other Ethernet device, an Ethernet hub, switch, or router is required.

QIs any Quality of Service (QoS) implemented on the VT2142 Voice Gateway?

AAlthough VoIP service is typically best-effort, the VT2142 provides upstream voice prioritization to ensure that upstream voice data has priority over other Web data. This ensures good voice quality even during heavy upstream data transfers, such as e-mail synchronization or file sharing.
