0
Force Transmit LOS (To the Line Side)
This bit permits the user to configure the transmit direction circuitry
(within the channel) to transmit the LOS pattern to the remote terminal
equipment, as described below.
0 - Configures the transmit direction circuitry to transmit “normal” traffic.
1 - Configures the transmit direction circuitry to transmit the LOS
Pattern.

Single Rail Mode
This bit can only be set if the LIU Block is also set to single rail mode.
See Register 0x0FE0, bit 7.
0 - Dual Rail
1 - Single Rail

Framer Loopback Selection
These bits are used to select any of the following loop-back modes for
the framer section. For LIU loopback modes, see the LIU configuration
registers.

TYPES OF LOOPBACK SELECTED

Normal Mode (No LoopBack)
01
Framer Local LoopBack:
When framer local loopback is enabled, the transmit
PCM input data is looped back to the receive PCM out-
put data. The receive input data at RTIP/RRING is
ignored while an All Ones Signal is transmitted out to
the line interface.
10
Framer Far-End (Remote) Line LoopBack:
When framer remote loopback is enabled, the digital
data enters the framer interface, however does not
enter the framing blocks. The receive digital data from
the LIU is allowed to pass through the LIU Decoder/
Encoder circuitry before returning to the line interface.
11
Framer Payload LoopBack:
When framer payload loopback is enabled, the raw
data within the receive time slots are looped back to the
transmit framer block where the data is re-framed
according to the transmit timing.
