REMOTE CONTROL INTERFACE
When installed in an IMUX 2000 remote controllable shelf, the RFL VF-15C module can be operated
under local or remote control. 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 VF-15C reports itself as a “Type 78” module when installed in an E1 system, and reports
itself as a “Type 69” module when installed in a T1 system.
“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 two “P” codes for the RFL VF-15C when operated in “normal” mode in T1 or E1 systems:
P1 and P2. There are six “P” codes for the RFL VF-15C when operated in “enhanced” mode in T1 or
E1 systems: P1, P2, P3, P4, P5 and P6. 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). The binary
representation is more useful for setting and interpreting the “P” codes, since each binary digit (0 or 1)
corresponds to the ON or OFF setting for a particular switch on the module. Table 5 describes the
meanings of the “P” codes for the RFL VF-15C in normal mode. Table 6 describes the meanings of the
“P” codes for the RFL VF-15C in enhanced mode.
A typical RFL VF-15C response to a “CONFIG?” query of a T1 or E1 system in normal mode looks
like this:
* OK
CHANNEL CARD 3, TYPE 78 (or 69)
UNDER REMOTE CONTROL
SVCE = ON
P01 = 3 (B00000011)
P02 = 1 (B00000001);
NOTE
When using binary numbers with a SET command, they must be preceded 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
