Reserved: This bit should always be ignored.
Loss of Signal, DS1 Channel n: Each DS1 channel is monitored for loss
of signal, which sets the associated bit LOSn to 1. The selection of monitor-
ing transmit DS1 channels or receive DS1 channels is determined by the
state written to control bit 1LOSSEL, bit 6 in register 20H. A 1 selects the
transmit DS1 channels. A DS1 channel loss of signal is defined as between
eight and sixteen DS2 frames of consecutive 0s. Recovery occurs after the
first 1 is detected.
Reserved: This bit should always be ignored.

Device ID 0: This bit is used to identify whether an M13X or an M13E
device is installed in an application. If this bit is always 0 then the device is
an M13X device. If this bit is a read/write bit then it is an M13E device. The
M13E device is the predecessor of the M13X device.
Internal DS1 Idle Channel/Loopback: The IDLn bits in this register are
used for generating and transmitting a DS1 idle pattern or for setting up a
local DS1 loopback for channel n. When register 1EH is written with a code
to disconnect the loopback on a channel in this register, and the corre-
sponding IDLn bit is written with a 1, the M13X generates and transmits a
DS1 idle pattern in that channel which is determined by the idle code selec-
tion bits (IDLB and IDLA in location 02H). When a code to connect a loop-
back on a channel in this register is written to register 1EH, and a 1 is
written into the corresponding IDLn bit, the DS1 channel is looped back
instead. The loopback is from the receive to the transmit direction. When
the IDLn bit is written with a 0, the DS1 transmit source is from the chan-
nel’s DTn/CTn leads.
