PERATION
Introduction This chapter describes the screens, menus, and parameters applicable to the DSU
MP card that are associated with the PRISM 3060-10 terminal interface, an
application program embedded inside those units. Chapter 3 discusses the screens
and menus associated with the front panel interface. Although the options are
essentially the same for both interfaces, the terminal interface shows more
parameters on each screen.
System
Description The Terminal Interface requires an ANSI-compatible VT100 terminal (ASCII), or
a computer running an ANSI terminal emulation program. The Terminal Interface
utilizes ASCII break and escape functions, which are implemented differently by
the various terminal emulation programs. The documentation supplied with the
terminal emulation program should be consulted for further reference.
In addition to the TR 54016 and T1.403 protocols, proprietary messages can be
sent over the facility data link (FDL) from the near-end unit to the far-end unit. A
local RS-232 terminal connected to the unit may access a far-end unit. 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.
Interface
Connection
The terminal may be connected to either of two 6-pin serial RS-232 ports on the unit.
One of the modular ports is a pair of daisy-chain type rear panel connectors labeled
NMS IN . The other port is labeled SUPV . Refer to NMS Connection on page 11 for
further information. Cables are available for most typical connections. Standard cables
and ordering numbers are listed in Ordering Numbers on page 66. Contact TXPORT
for any assistance in cable selection.
A serial bit rate of 1200, 2400, 9600, or 19200 bps may be selected using the front
panel control (see Supv Bit Rate on page 33).
Both serial ports support the same custom protocols which allow the terminal
interface or the TXPORT 8100A Site Controller to request and receive
performance and configuration data from the unit. The unit automatically
determines which protocol is needed.
