H Integral modem for standalone DSU/CSUs.
H Asynchronous (async) terminal interface support.
H Telnet access for remote async terminal operations.
H Network management provided through industry-standard Simple Network
Management Protocol (SNMP).
DTE Drop/Insert (DSX-1) Interface
The DTE Drop/Insert interface allows DTEs/PBXs that support the DS1 signal
format to share the T1 network with other high-speed equipment. This is available
on 2-port and 4-port DSU/CSUs.
Alarm Message Capability
The DSU/CSU can be attached, either locally or remotely, to an ASCII terminal or
printer to display or print alarm messages. Alarms can also be displayed on a PC
that is using a terminal emulation package.
Front Panel Emulation
The DSU/CSU offers functionality through Front Panel Emulation software that is
similar to that provided by the DSU/CSU front panel. The functionality of the front
panel is available by clicking on the function keys with the mouse rather than by
pressing keys from the actual front panel.
Integral Modem
The standalone DSU/CSUs contain an integral low-speed (2400 bps), V.22bis
dial modem that enables communication with remote devices such as another
316x DSU/CSU, an ASCII terminal or printer, or a PC running the 3100 Series
Front Panel Emulation software.
Async Terminal Interface Support
The DSU/CSU can be configured and managed from an asynchronous (async)
terminal. The async terminal’s full screen display uses a menu hierarchy similar
to the DSU/CSU’s front panel. You can perform device management and
configuration operations as if you are using the DSU/CSU’s front panel, but you
do not have the limitation of the 2-line, 16-character LCD.
Telnet Access
Remote async terminal operations can be performed using Telnet access. Telnet
is a Transmission Control Protocol/Internet Protocol (TCP/IP) service that
supports a virtual terminal interface.
