7.6.4 T_COND_SIG
Organization: 32 bytes × 8 lines
Base address: 400h
Index: 10h
Type: Read/Write
Function: Stores the transmit conditioned signaling.
Initialization: Initialize to the conditioned signaling value for the channel. This value typi-
cally depends on the type of channel unit that is connected. For example, a Foreign
Exchange Office (FXO) needs a different conditioning value than a Foreign Exchange
Subscriber (FXS).
Format: One nibble per byte, two bytes per word, 16 words per line. Refer to the following
table.
