CH4-0
Channel 4-0.
This 5 bit number specifies the channel time HDLC1 will be attached to if
enabled. Channel 0 is the first channel in the frame. Channel 23 is the last channel available
in a T1 frame. If enabled in a channel, HDLC data will be substituted for data from DSTi on
the transmit side. Receive data is extracted from the incoming line data before the elastic
buffer.

Custom Pulse.
These bits provide the capability for programming the magnitude setting for
the TTIP/TRING line driver A/D converter during the first phase of a mark. The greater the
binary number loaded into the register, the greater the amplitude driven out. This feature is
enabled when the control bit 3 - CPL of the Custom Tx Pulse Enable Register - address 11H
of Page 2 is set high.
