REMOTE CONTROL INTERFACE
When installed in an IMUX 2000 remote controllable shelf, the RFL TMX and TMR modules can be
operated under local control using DIP switches, or remote control using either Simple Command
Language (SCL) or Network Management Software (NMS). When under remote control, certain
configuration parameters can only be changed through the RS-232 remote port on the multiplexer. The
remote interface for these modules involves two codes: a “P” (parameter) code, and an “S” (status)
code. See the IMUX 2000 instruction manual for more information on the remote control interface.
The RFL TMX reports itself as a “Type 122” module when installed in a T1 or E1 system.
The RFL TMR reports itself as a “Type 123” module when installed in a T1 or E1 system.
REMOTE CONTROL USING SCL
“P” CODES
“P” codes, when used in the parameter field on a “SET” command, allow the user to set certain
parameters on the module by remote control, just like setting the switches on a module under local
control. “P” codes also appear in the response to a “CONFIG?” query, showing the current parameter
settings on the module.
There are eleven “P” codes for the RFL TMX module: P1 through P11 . There are eighteen “P” codes
for the RFL TMR module: P1 through P18. Each of these P codes can be a decimal number from 0 to
255, which can also be represented as an eight-digit binary number (in parenthesis). Table 13 describes
the meanings of the “P” codes for the RFL TMX module and Table 17 describes the meanings of the
“P” codes for the RFL TMR module.
A typical TMX or TMR response to a “CONFIG?” query of a T1 or E1 system looks like this:
* OK
CHANNEL CARD 3, TYPE 122 (or 123)
UNDER REMOTE CONTROL
SVCE = ON
P01 = 3 (B00000011)
NOTE
When using binary numbers with a SET command, they must be preceeded by the letter “B”
as shown in the following example:
<MULTIPLEXER ADDRESS>:<CARD ADDRESS>:SET:P1 = B00000011;
Besides using the P code, it is also possible to turn module service on or off by sending one of the
following in the parameter field with a SET command:
SRVC = ON
SRVC = OFF
For example: 15:C6:SET:SRVC = ON
