2-WIRE IDSL LINE DRIVER RACK CARDS
2. Introduction
2.1 Description
The 2-Wire IDSL Line Driver Rack Card allows synchronous or asynchronous data
to be transmitted up to 11 miles (17.7 km) over one or two twisted pair (2- or
4-wire). Supporting synchronous speeds up to 128 kbps and asynchronous speeds
up to 38.4 kbps, the Card is perfect for LAN interconnection or high-speed
Internet links.
To compensate for poor line quality, the Card supports 2B1Q encoding, automatic
equalization, and auto gain control. The Card is fully SNMP manageable using the
Managed Micro Rack SNMP/HTTP Card (part number RM261C-SNMP). Software
configuration is performed via the VT100™ screens. Swappable interface driver
boards and interface cards allow you to easily change applications between
10BASE-T, G.703, RS-530, V.24, V.35, or X.21. The Card also features convenient
front-panel diagnostic switches and LEDs that allow for easy setup, configuration,
and testing.
The Card is designed to fit into the 16-Port Managed Micro Rack (part number
RM260), a 2U-high (3.5") rack chassis. This chassis uses a mid-plane architecture,
allowing front cards to be plugged into different rear cards.
