Remote Terminal Adaptors
Remote Terminal Adaptors (RTAs) are basically serial connection blocks which provide a
number of ports depending on type. RTAs come in three main varieties, the RTA 8 (providing
8 ports) and RTA 16 and RRC16 (providing 16 ports). Each unit is available in a number of
variations as shown in the next table.

Long Distance Module (LDM)
The RIO Long Distance Module (LDM) allows you to extend your RIO sy stem via a leased
line. Using a RIO Long Distance Module you can make connecti ons over thousands of miles
using synchronous (X.21/X.21bis) or asynchronous i nterfaces. The long distance module
comprises two long distance units (LDUs). One is installed at the host site and the other at
the remote site. See also Installing a Long Distance Module (LDM) on page 177 in
