(Target to
Controller)
Group GRP 1 byte Command or Query
Group a modulator/demodulator pair into a modem
A grouped mod and demod will respond to either address
0=Both sides ungrouped
1=Left side (as viewed from back of chassis) grouped
2=Right side grouped
3=Both sides grouped
Example: GRP=3 (both sides of chassis are grouped into modems) GRP=
GRP?

GRP#
GRP$
GRP^ GRP? GRP=x
T1 Line
Build-Out LBO= 1 byte, value of
0 though 4
Command or Query.
Valid only for T1 interface, where:
0=0 to 133 feet
1=133 to 266 feet
2=266 to 399 feet
3=399 to 533 feet
4=533 to 655 feet
Example: LBO=2 LBO=

(see description
arguments)
IP Address IPA= 18 bytes
numerical
Command or Query
Used to set the IP Address and network prefix for the 10/100
BadeTX Ethernet management port, in the format:
xxx.xxx.xxx.xxx.yy where:
yy is the network prefix (0 to 31)
Example: 010.006.030.001.24 IPA=
IPA?
IPA*
IPA#
IPA? IPA=xxx.xxx.xxx.xxx
.yy
(see description of
arguments)
Request to Send RTS= 1 byte, value of
0, 1, 2
Command or Query
Defines how RTS/CTS will operate at the main data interface
0=RTS/CTS Loop, No Action
RTS and CTS are looped, so that CTS echoes the state of RTS,
but RTS does not control the ON/OFF state of carrier.
1=Loop, RTS Controls TX O/P
RTS and CTS are looped, so that CTS echoes the state of RTS
and RTS controls the ON/OFF state of carrier (in order words,
the modem will not bring up its TX carrier until RTS is asserted.
2=Ignore RTS, Assert CTS
Example: RTS=0 (RTS/CTS Loop, No Action) RTS=
RTS?
RTS*
RTS#
RTS^ RTS? RTS=x
(see description of
arguments)
HSSI handshake
control (valid only
for HSSI
interface) HHC= 1 byte, value of
0,1
Command or Query.
Defines how TA/CA control the HSSI interface.
0 = TA to CA loop (default)
1 = RR control CA, TA control Tx output.
Example: HHC=0 (TA to CA loop) HHC=
HHC?
HHC*
HHC#
HHC^ HHC? HHC=x
