9.2 Receive Side Code Generation
In the receive direction there are also two methods by which channel data to the backplane can be
overwritten with data generated by the DS2152. The first method, which is covered in Section 9.2.1, was
a feature contained in the original DS2151, while the second method, which is covered in Section 9.2.2, is
a new feature of the DS2152.
9.2.1 Simple Code Insertion
The first method on the receive side involves using the Receive Mark Registers (RMR1/2/3) to determine
which of the 24 T1 channels should be overwritten with either a 7Fh idle code or with a digital milliwatt
pattern. The RCR2.7 bit will determine which code is used. The digital milliwatt code is an 8-byte
repeating pattern that represents a 1kHz sine wave (1E/0B/0B/1E/9E/8B/8B/9E). Each bit in the RMRs
represents a particular channel. If a bit is set to a 1, then the receive data in that channel will be replaced
with one of the two codes. If a bit is set to 0, no replacement occurs.

Receive MARK Registers.
0 = do not affect the receive data associated with this channel
CH1
RMR1.0
1 = replace the receive data associated with this channel with
either the idle code or the digital milliwatt code (depends on the
RCR2.7 bit)
9.2.2 Per-Channel Code Insertion
The second method involves using the Receive Channel Control Registers (RCC1/2/3) to determine
which of the 24 T1 channels off the T1 line and going to the backplane should be overwritten with the
code placed in the Receive Channel Registers (RC1 to RC24). This method is more flexible than the first
in that it allows a different 8-bit code to be placed into each of the 24 T1 channels.
