receive channel.
After reset, the B- and D-channel shift registers and shadow registers are initialized to all ones.
13.2.2
The maximum transmission rate for each GCI/IDL port is 144 Kbps: the sum of two 64-Kbps B channels
and one 16-Kbps D-channel. Frames of B
receive side.
Because the reception and transmission of information on the GCI/IDL interface is deterministic, a
common interrupt is generated at the 2-KHz rate. It is expected that a common interrupt service routine
services the transmit and receive registers.
After reset, the B- and D-channel shift registers and shadow registers are initialized to all ones.
