Preliminary W6691
Publication Release Date: Sep 2001
61 Revision 1.1
XACT Transmitter Active
Setting this bit activates the D_ch HDLC transmitter. This bit can be read. The transmitter must be in active
state in order to transmit data.
Note:
The transmitter is deactive after hardware reset or software reset.
S_RLPD S Interface Remote Loopback with D channel Loopback
Setting this bit to "1" activates the remote loopback function. The received 2B channels from the S interface
are looped to the transmitted 2B channels of S interface. The received D channel from the S interface is also
looped to transmitted D channel of S interface in the loopback function.
MFD Multiframe Disable
This bit is used to enable or disable the multiframe structure on S/T interface :
0 : Multiframe is enabled
1 : Multiframe is disabled
L2_DLP Layer2 Digital Loopback
Setting this bit activates the layer2 digital loopback function. The transmitted digital 2B+D channels are
looped to the received 2B+D channels. Note that after hardware reset, the internal clocks will turn off if the S
bus is not connected or if there is no signal on the S bus. In this case, the C/I command ECK must be issued
to enable loopback function.
S_RLP S Interface Remote Loopback
Setting this bit to "1" activates the remote loopback function. The received 2B channels from the S interface
are looped to the transmitted 2B channels of S interface. The received D channel from the S interface is
not
looped to transmitted D channel of S interface in this loopback function.
