PERATION
Introduction This chapter describes the screens and menus associated with the TxPORT PRISM
3001 terminal interface, which is a firmware application program embedded inside
the unit.
The terminal is connected to a 6 -pin modular jack on the PRISM 3001 . Refer to
the Installation chapter for more information on user connections. Cables are
available for most typical connections. Standard cables and ordering numbers are
listed in Table 1-2 on page 1-8. Contact TxPORT for any assistance in cable
selection.
In addition to the 54016 and T1.403 protocols, proprietary messages can be sent
over the facility data link (FDL) from the near-end PRISM 3001 to the far-end
PRISM 3001. A local RS-232 terminal connected to the unit may access a far-end
PRISM 3001. Thus, the remote unit may be queried for status and statistics,
configured, or looped for testing as if the terminal is connected to it directly.
System
Description The terminal interface requires an ANSI-compatible VT100 terminal (ASCII), or a
computer running an ANSI terminal emulation program. The terminal interface
uses ASCII break and escape functions, which are implemented differently with
various terminal emulation programs. The software supplied with the emulation
program should be consulted for further reference.
The 3001 unit has two serial interface RS-232 ports. Either of these ports may be
used for the terminal interface program or as a connection to the EM8000 Element
Manager or an 8100A Site Controller. One port is a pair of daisychain-type rear
panel connectors labeled NMS IN and NMS OUT. The other port is located on the
front panel and labeled SUPV. Serial bit rates of 1200, 2400, 9600, or 19200 bps
may be selected using option switch S6 (refer to the SUPV and NMS port bit
rates, Configuration Switch S6 on page 2-5).
Both serial ports support the same custom protocols that allow the terminal
interface, EM8000, or 8100A to request and receive performance and configuration
data from the unit. The unit automatically determines which protocol is needed.
Modem
Compatibility
The PRISM 3001 terminal interface supports the use of an AT-command-set-
compatible modem on either, or both, of the NMS IN and SUPV serial ports. The
modem should be optioned to ignore DTR, enable auto answer, inhibit command
echo, and return verbose result codes.
