LMC DEBUTS LOW-COST T1+E1 WAN ADAPTER WITH ONBOARD CSU/DSU.

LAN Media Corporation (LMC), San Jose, Calif., has introduced a new Wide Area Network (WAN) adapter for PCI that supports both T1 and E1 line interfaces on the same card.

The new adapter, priced at $749, includes full CSU/DSU functionality on the adapter card itself, thereby eliminating the requirement for an external device to complete the WAN connection with a service provider.

The company has announced support for Open Source operating systems in general, and for the Linux operating system environment in particular. The company stated that Solaris drivers would also be available with first customer shipments.

The new adapter, called the LMC1200P T1+E1 WAN Adapter for PCI, includes several innovative features to enhance its flexibility and performance. For example, selections for T1 or E1 operation, short haul or long haul signaling (CSU/DSU), and 100 ohm or 120 ohm impedance are all made within software to enable the adapter to operate in a wide range of environments.

Additional flexibility is reflected by the inclusion of special hardware headers to enable synchronization with other communication devices via transmit-clock-in and receive-clock-out. The adapter's bezel provides a standard RJ-48 connection and four separate LED's for precise status display and telco service alarms.

As with all LMC high performance WAN adapters, the LMC1200P utilizes a state-machine architecture with HDLC functionality occurring in hardware. The result is very low latency and a reduced component count that enhances reliability.

Along with release of its new T1+E1 Adapter LMC has announced the availability of driver source code for Linux and several other Open Source operating systems including BSD/OS, FreeBSD, and NetBSD.

The new drivers, including documentation, will be included with any LMC WAN Adapter shipment where UNIX or Linux is specified as the operating system environment and will also be available on the company's FTP site at no charge.

"We are very excited about the growing trend toward combining open source operating systems with open hardware systems for networking applications," said Dave De Puy, chief operating officer for LMC. "Thanks to this convergence, users have the opportunity to experience the benefits of very reliable, high performance routers at a fraction of the cost associated with their proprietary counterparts."

He went on to say, "For example many of our customers are using standard out-of-the-box PC's, directly connected to the WAN with LMC Adapters, running firewall and routing applications. Not only are they paying much less than the cost of dedicated proprietary routers and CSU/DSU equipment, they are securing their networks at the very point of entry."

The LMC1200P T1+E1 WAN Adapter is available now. Two versions have been released. The LMC1200P-U ships with LMC's full set of Linux and Open Source driver source code. It is also available as the LMC1200P-S, which includes drivers for Solaris operating systems. Both are priced at $749, including software, documentation, and a one-year limited warranty.

LAN Media Corporation is a leading developer of high performance WAN technology and products based on industry standard bus architectures for the next generation of WAN solutions. The company is located in Sunnyvale, Calif.
