SCNT1 Family Reference Design Board
The SCNT1 Family Reference Design Board (SCNT1-
RDB) is a printed-circuit board platform that provides
an example implementation of an ISDN NT1 circuit
based on the Lucent T7256 or T7234. In addition, it can
be configured as an ISDN terminal adapter (TA) based
on the Lucent T7237. With the T7234 or T7256
installed, it is a fully functional NT1, with the exception
of power status monitoring circuitry (which can be
added by the user). It can be used as an evaluation
platform as well as a reference design. With the T7237
installed, it can be used to develop U-interface terminal
adapter applications (external control hardware is
required in this case). For complete information, con-
sult the SCNT1 Family Reference Design Board Hard-
ware User Manual (document # MN96-011ISDN).
SPEC_V2 Test Board
The SPEC_V2 is a circuit board that connects to a
T7256 or T7237-based product in order to provide vari-
ous control and status operations. The SPEC_V2
board is controlled via an RS-232 terminal interface
(DB-25 connector J2). A PC running a standard termi-
nal emulation package can be connected to J2 via one
of the PC’s COM ports.
The SPEC_V2 allows the operations in Table 33 to be
performed on the unit under test (i.e., the SPEC_UUT).
Table 33. SPEC_V2 Functions
Note: Optional command-line parameters are shown in brackets.
Following is an explanation of the command syntax for
each command. Command-line parameters enclosed
in brackets [ ] represent optional parameters.
rd
['hex-addr']
Read SCNT1 register(s).
The
rd
command, when entered with no command line
parameters, reads and displays each internal register
address and the corresponding contents in the follow-
ing format, where the top row (beginning with A:) dis-
plays the hexadecimal address and the bottom row
(beginning with D:) displays the register data corre-
sponding to the address directly above it. For example,
if each register contained its address, the resulting dis-
play would appear as follows:
A:00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d
0e 0f 10 11 12 13 14 15 16 17 18 19
D:00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d
0e 0f 10 11 12 13 14 15 16 17 18 19
When the
rd
command is entered with the optional
command line parameter representing the hexadecimal
address of the desired register to read (for example,
“rd c”
), the resulting display is as follows:
Addr: 0x0c Data: 0xff
mon
['hex-addr'] [/s]
Continuously monitor SCNT1 register(s).
This command is identical to the rd command, with the
following exception—the address and data of the spec-
ified register (or all registers if no ‘hex-addr’ parameter
is specified) are continuously read and updated on the
terminal screen. In addition, there is an optional param-
eter, /s, that can be specified. This causes each suc-
cessive register refresh to appear on a new line (as
opposed to the same line). Thus, the terminal display
will scroll as the values are updated. This can be useful
for terminal emulators that have a scrollback buffer,
since a history of the register contents and changes is
available on screen.
To exit this mode, press the ESC key.
wr
'hex-addr' 'hex-data'
Write SCNT1 register.
This command allows ‘hex-data’ to be written to the
register at ‘hex-addr’. For example, to write the value
0xef to register address 0x0a, the following would be
entered.
wr a ef
