New Low Cost T1+E1 WAN Adapter With Onboard CSU/DSU
Aug 14th, 20:35 UTC
Along with release, ADCOMTEC has announced the
availability of driver source code for Linux and several other Open Source
operating systems ADCOMTEC today announced the availability of 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 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 the new T1+E1 Adapter ADCOMTEC has announced the
availability of driver source code for Linux and several other Open Source
operating systems including BSD/OS, FreeBSD, and NetBSD.
The LMC1200P T1+E1 WAN Adapter is available this month. 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.
