REMOTE CONTROL INTERFACE
When installed in an IMUX 2000 remote controllable shelf, the RFL VF-10D 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-10D reports itself as a “Type 75” module when installed in a T1 or E1 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 is one “P” code for the RFL VF-10D when operated in “normal” mode in T1 or E1 systems: P1 .
There are three “P” codes for the RFL VF-10D when operated in “enhanced” mode in T1 or E1
systems: P1, P2, and P3. 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-10D in normal mode. Table 6 describes the meanings of the “P” codes for the RFL
VF-10D in enhanced mode.
A typical RFL VF-10D response to a “CONFIG?” query of a T1 or E1 system in normal mode looks
like this:
* OK
CHANNEL CARD 3, TYPE 75
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
