ISPs and corporates thinking about upgrading their connection to the Net, could do worse than looking at Tricom's PortMaster 3. The PortMaster is an integrated access server designed "to cut communication overheads by reducing facility costs incurred by modem racks, cables and power supplies".
The switch supports ISDN, modem, router, Frame Relay and leased-line through a single point of presence. It uses a digital technology to intelligently switch analogue and ISDN network traffic onto high-bandwidth capacity lines (see feature PC Week 26 November). This allows providers to offer low-cost, high-density flexible lines (the switching feature means the client pays only for the bandwidth used).
Martin Bond, Tricom's marketing manager, said, "PortMaster 3 can maintain numerous communication protocols including Frame Relay, it also provides an ideal migration path for enterprise wide digital connectivity."
The PortMaster 3 offers one or two primary rate ISDN ports, six expansion slots for True Digital modem cards, ethernet (BNC, AUI, 10BaseT) and an asynchronous 115.2Kbps console port. The True Digital modem cards are hot-swappable and support 10 33.6Kbps (V.34) modems per card.
