9.4 T1 Receive-Side Digital-Milliwatt Code Generation
Receive-side digital-milliwatt code generation involves using the receive digital-milliwatt registers
(T1RDMR1/2/3) to determine which of the 24 T1 channels of the T1 line going to the backplane should
be overwritten with a digital-milliwatt pattern. 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 T1RDMRx registers
represents a particular channel. If a bit is set to a 1, then the receive data in that channel is replaced with
the digital-milliwatt code. If a bit is set to 0, no replacement occurs.
