The ADTRAN FSU is a stand-alone frame relay access device (FRAD) that
provides a cost-effective means of transporting multi-protocol data over
frame relay networks. The ADTRAN FSU provides an easy-to-use interface
for customers migrating existing services or developing new applications
for operation over frame relay networks.
The FSU provides two independent DTE interfaces for connecting non-
frame relay devices to the frame relay network. The DTE ports support
synchronous data rates from 2.4 to 512 kbps and asynchronous from 2.4 to
38.4 kbps. Both EIA-232 and V.35 physical interfaces are available for con-
nection to the customer’s DTE equipment. The FSU’s concentrator feature
allows the connection of two frame relay devices to a single frame relay
network interface.
The FSU may be purchased with an integral 56/64 DDS DSU/CSU or
an external DSU/CSU may be connected to the DCE interface. Network
speeds up to 512 kbps and both EIA-232 and V.35 physical interfaces are
supported through the DCE port.
The FSU supports SNA, SDLC, Bisync, SLIP, IP, PPP (both synchronous
and asynchronous), frame relay, BOP, and asynchronous protocols. The
DTE ports can be configured independently, providing support for multi-
protocol applications.
Embedded SNMP and Telnet are available in-band. SNMP is provided
with support for RFC 1315 and MIB II. Through the Management
Information Base (MIB)-II standard and an ADTRAN-supplied enterprise
MIB, the FSU can be configured, monitored, and diagnosed using standard
SNMP network management programs such as HP OpenView
®
, NetView
®
,
and SunNet Manager
®
.
Complete control, configuration, and diagnosis are available through a
16-position keypad and a two-line by 16-character LCD display. A VT100
terminal configuration and control mode is also available through the con-
trol port. Flash download capability is implemented for installation of new
features and enhancements.
