PERATION
Introduction This chapter describes the screens and menus of the Verilink PRISM 3030 terminal
interface, an application program embedded in the unit. The Operations chapter
discussed 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 with
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 can access a far-end unit. Thus, the
remote unit can be queried for status and statistics, configured, or looped for
testing as if the terminal is connected to it directly.
Interface
Connection
The terminal can 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 Supervisory Port
Connection on page 16 for further information. Cables are available for most
typical connections. Standard cables and ordering numbers are listed in Ordering
Numbers on page 121. Contact Verilink for any assistance in cable selection.
A serial bit rate of 1200, 2400, 9600, or 19200 bps can be selected using the front
control panel (see Supv Bit Rate on page 42).
Both serial ports support the same custom protocols which allow the terminal
interface or the Verilink 8100A Site Controller to request and receive performance
and configuration data from the unit. The unit automatically determines which
protocol is needed.
Modem
Compatibility
The terminal interface supports 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.
