VX-2039 Dual 4-Wire Audio Adaper As ISDN becomes more widely available, access to dial-up and private 4-wire circuits is increasingly difficult. The VX-2039 4-Wire Adapter for ISDN provides two independent true 4-wire circuits on a single ISDN-2 service, either in a 1U-high rackframe or in a robust aluminium enclosure for desktop / portable use. Two independent 4-wire circuits are presented on balanced line-level XLRs, for simple integration with existing comms equipment. Both ports can be used for conventional telephone calls to PSTN numbers via ISDN, as well as 4-wire circuits directly over ISDN or to PSTN hybrids. A standard TouchTone telephone can be used to set up outgoing and manually answered incoming calls, and the user may select automatic or manual call answering. Status indications are provided on both portable and rackmount models. |

The Anatel 200 Voice Adapter The Anatel 4000 is a simple, pocketable device which converts the ISDN S-Bus to two analogue telephone ports. With the Anatel, you can use ISDN-2 for telephone calls, faxes, modem access (to the web or whatever) and to connect telephone codecs (such as the HotLine and Vector) via ISDN. With just one ISDN2 connection and a Connect 200 users will benefit from greater flexibility of existing equipment:
Both analogue and digital services can be distributed around the house or office with just one cable |
